This chapter summarizes the possibilities ofdisplay and operation with the SF 3 controlblock.

1.1 Display and operating units on the SF 3 control block

The diagnostic interface of the SF 3 control blockcan be used either for programming or diagnosiswith a PC or for communication with a displayand operating unit (ABG).

The SF 3 control block can be operated in auser-friendly manner with the aid of a displayand operating unit (ABG), as most ABGs have atext display and keyboard. Simple conventionaloperation by means of switches and keys, aswell as the display of operating states by meansof LEDs, is also possible via the digital in-puts/outputs.

Depending on the display and operating unitused, the following applications are possible:

– displaying user-defined texts (e.g. outputtingmessages);

– displaying values (e.g. number of items,pages, etc.);

– entering parameters (value entry, machinediagnosis, sequence control).

The display and operating units are controlled bymeans of special program or function modules(CMP/CFM). These software modules providethe functions for communication between SF 3and certain display and operating units. Thesesoftware modules are therefore also referred toas drivers.

The \LIB directory of the FST software packagecontains various MAK files ("Make" files) for thispurpose. Depending on the ABG type, you can"make" (create) the appropriate software mo-dules.

1-4 9708b

The FST software package contains the follow-ing programs and functions for user-friendly textwriting, programming and commissioning of thedisplays:

– display editor for creating the display textswhich are to be shown later on the ABG;

– functions for creating out of MAK files theappropriate software modules for a display.Depending on the display: a) in the menu Utilities via Include moduleb) in the display editor via Generate CMP/CFM

for standard mode.

– Emulators for Festo ABGs, in order toemulate the ABGs during commissioning(with PC connected).

– A program for testing the displays and withwhich you can access texts stored in thedisplay.With the display editor you can also outputtexts from the PC on the display.


9708b 1-5

1.1.1 Division of ABG types

Various display and operating units can be usedwith the SF 3 control block. The followingfunctions are possible:

– Display textoutput texts which are stored in the SF 3

(internal texts)- output texts which are stored in the SF 3

(external texts)- output variables (values) from a user

program currently running

– Keyboard scanning (direct key monitoring; theappropriate flag must be scanned cyclicallyby program)

– Keyboard buffer (enter up to five charactersin an intermediate memory/register, indirectscanning)

– Switch on/off key LEDs

Displays enable the most important alphanumeri-cal characters to be represented. Depending onthe ABG, 1 to 4 lines with 16 to 40 characterscan be represented. The display texts can bestored both in the SF 3 ("standard mode") and inthe ABG.

Entries on the keyboard are scanned by pro-grammed cyclic monitoring of the keys. Severaldispay and operating units have a keyboardbuffer which intermediately stores the valuesentered.

As a further possibility, additional LEDs on theindividual keys can be switched on (e.g. with theABG2).

1.1.2 Operating principle of the software modules

The software modules for the currently availabledisplay and operating units are accessed cycli-cally from a program. Communication betweenthe calling program and the software module ismade by means of operands, e.g. registers, flagsand special function units (FU).

1-8 9708b

The ABGs are connected to the diagnosticinterface of the SF 3 (RS232). The softwaremodule controls communication to the display viathis RS232 interface.

A distinction can be made between two types ofsoftware modules according to their function:

– Keyboard modules or entry driversSoftware modules used for scanning/monitor-ing the key functions of display and operatingunits.

– Text modules or display driversSoftware modules used for controlling the textoutput functions of display and operatingunits.


9708b 1-9

1.1.3 Text output procedure (operating modes)

The following posssibilities exist for showingtexts on the display of the ABG, depending onthe display type:

– Texts in the SF 3 control block (internal texts)This possibility is referred to as standardmode and is generally suitable for all types ofdisplay with serial interface. The texts can bemodified easily and quickly, but they occupymemory space in the SF 3 and requirecapacity for calculating (thereby reducing theperformance of the system.

– Texts in the display (external texts) - RAM mode – for displays with

integrated RAM memory- EPROM mode – for displays with

EPROM memory - Field bus mode – for displays with

RAM or EPROM memory and field bus interface.

This possibility reduces the amount of dataexchanged between the SF 3 and the dis-play. The texts do not occupy any memoryspace in the SF 3 and thereby reduce theprogram cycle time. The texts cannot, how-ever, be modified so easily.


1-10 9708b

Selecting the operating mode

Depending on the commissioning phase, youmust decide whether the text is to be stored inthe SF 3 control block or in the display. Thefollowing considerations should help you inmaking this decision:

• Which operating mode makes the displaypossible?

• Is the text to be stored irrespective of batterycapacity and interference?

• Should it be possible to quickly revise thetext?

• Is there sufficient storage space in the SF 3control block for the texts?

• Will the cycle time for program processing beunreasonably extended due to the transfer oftexts from the PLC to the display?

During the development phase, it is a good ideato store display texts in the SF 3 (standardmode, texts in the display). It then takes lesstime to modify texts.


9708b 1-11

1.2 Summary of software modules for the SF 3 control block

The following MAK files for creating softwaremodules are an integral part of the FST softwarepackage and are installed in the library directory(\LIB). You can incorporate software modulesfrom the directory \LIB into the current projectwith the function Include module.

1.2.1 Selecting the software modules

Proceed as follows in order to select the correctsoftware module:

1. Look for your dispay in the following table andfor the desired operating mode in the col-umns "Function" and "Brief description of theoperating mode."

2. Select one of the MAK files in the appropriateline. Files with the underline (_) are used forcreating a CMP, those with a circumflex (^)are used for creating a CFM.

3. In the key to the MAK file you will find outhow the software module is to be created.– with the display editor of the FST200,

generate function CMP/CFM for standard mode.

– with the FST software, function Includemodule

The further procedure and detailed informa-tion can be found in the following chapters:– Creating the software modules

⇒ Chapter 3– Description of the software modules and

access in the user program⇒ Chapter 4

9708b 1-13

When the FST200 as from version 3.2 – revision8 (as at 8/97) is installed, these MAK files willautomatically be installed on your PC (directory\LIB). In order to display the version of your FSTsoftware, press key F10 in the main menu. Theversion will then be shown in the status line (e.g.3.2 - 0008).

The MAK files must be incorporated as softwaremodules into the current project with GenerateCMP/CFM for standard mode or with Includemodule.

1.2.2 MAK files for further displays and other controllers

Further displays or other controllers are alsosupported by MAK files. However, these are notan integral part of the FST200 software package.The display drivers supplied are imported auto-matically by the installation program.

Display drivers which are not an integral part ofthe FST200 software package must be importedinto the directory \LIB (library directory) with theaid of the FST software. Please refer here to therelevant documentation for the display driver.

1.2.3 Software, devices and accessories required

You will require the following for commissioningan ABG:

– SF 3 control block as from software versionV1.2 and valve terminal hardware of yourchoice. (Software version V 1.5 is required if youwish to use the module for characterinput/output via the diagnostic interface(3_ETMV5.MAK/3^ETMV5.MAK). You candisplay the version number with the functionOnline mode).

– Programming software FST200 with manual.

– Display and operating unit with suitableconnecting cable (see Appendix B).

1.3 Differences between SF 3 and SB202

All program modules which are available for theSB202 are also available for the SF 3. In thecase of the SF 3, function modules (CFM) canalso be used for controlling display and operatingunits. From the designation of the MAK file, youcan tell for which controller and module type thefile is intended.

Example:

2FD_240S.MAK3FD^240S.MAK

2.1 Accessing the display editor

A display file is part of a project. You mustalways select the project before the displayeditor is started.

You can only start the display editor from theFST software. To do this activate the functionConfiguration in the Utilities. Then enter theappropriate specifications in the mask Programcall (F4) (see following diagram).

These entries are made by the installationprogram when the FST software is installed.

Fig. 2/1: Specifications for program access

F4


9708b 2-5

The installation program enters all the necessaryinformation. By means of the parameters (#1 #2#3 #4), the display editor recognizes the com-puter configuration, the current project path andthe controller type used (see FST manualchapter 3.10.1).

The installation program enters Display editor asthe program name. If you activate the functionProgram execution under Utilities in the FSTsoftware, this name will appear in the selectionwindow (see diagram below).

You can start the program by activating thisentry. You can request a situation-related helptext with key F9, exactly as in the FST software.

Fig. 2/2: Accessing the program


2-6 9708b

2.2 Creating a display file

The display editor supports further functions inaddition to the editing of texts. When the displayeditor is accessed, you will see the choice offunctions (see following diagram). You can:

– edit new or existing display files,

– delete existing display files,

– print display files,

– load display files into an EPROM or into theRAM memory of the display,

– create a program module or function modulefor standard mode,

– exit the display editor.

In order to create a display file, activate thefunction Edit file.

Fig. 2/3: Function selection menu in the displayeditor


9708b 2-7

Your next step depends on whether the selectedproject:

– does not yet contain a display file or,

– already contains a display file.

Project does not contain any display files

If there is no file for the active project, only thefunction New file name will appear in the fileselection menu.

The function New file name enables you tocreate a new file in the current project. When thefunction is activated, the following window ap-pears.

Fig. 2/4: File selection menu

Fig. 2/5: Enter file name


2-8 9708b

Enter here a file name with maximum eightcharacters. This may consist of letters, figures orthe underline ( _ ). When the entry is confirmed,the display type selection will appear.

By selecting the display type, you communicateto the program whether the display consists of asingle line or of several lines and the controlcharacters which it can process. You can thenedit the file (see chapter 2.2.1).

Fig. 2/6: Select display type


9708b 2-9

Project already contains display files

If the project already contains display files, thefollowing file selection menu will appear:

Next to the file names you will see the displaytypes for which the files have been created. Youcan now select the file which you wish to edit.With the function New file name, you can addanother file to the project.

Fig. 2/7: Select file


2-10 9708b

2.2.1 The screen layout of the editor

When a file has been selected or created, theeditor is activated. The editing level depends onthe type of display selected. The name of thecurrent display file can be seen in the header.The diagram below shows the editing level for atwo-line display.

Fig. 2/8: Editing level of a two-line display


9708b 2-11

There are four windows:

– Control sequence window (top left): Showsthe control characters entered for the currentcursor position of the text window. All thesecontrol characters together are referred to asthe control sequence.

– Control character menu (top right): Containsthe control characters permitted for this typeof display together with an explanatory text.

– Text window: Enter here the text which is toappear later on the display.

– Valid set of characters (below right): Showsthe set of characters valid for the display.

When you are working with the keyboard and themouse, the same possibilities are available aswith the FST software.

Basic principles

A display file consists of text and controlcharacters. You normally enter the text charac-ters in the position in the text window where theyare to appear later on the display. The controlcharacters of some displays enable you torepresent texts in different ways (e.g. by under-lining individual characters) or similar. You cantherefore assign several control characters toeach position in the text. The maximum numberof control characters depends on the memory ofthe display and on the length of the controlsequence window. All the control characters ofone position are referred to as the controlsequence (see following diagram).


2-12 9708b

The control sequence window shows the controlsequence belonging to the current text charac-ters. If the cursor is placed in the position E ofTEXT, the control character ESC N will be seenin the sequence window.

How to transfer texts

1. Each position, beginning with the first (left-hand) position in the first row, is processedone after the other.

2. If a position contains a control sequence, thiswill be transferred before the text character.

3. The text character is transferred after the con-trol sequence (if this exists).

4. The next position is processed. This repeatsitself until all the text positions have been pro-cessed.

9708b 2-13

2.2.2 Editing mode

When the editor is accessed, the text modebecomes active. With function key F1 or byclicking the appropriate window, you can switchbetween the editing modes for:

– text or

– control characters

Depending on the mode, you can insert ormodify text or control characters in the file. Thetable below explains this briefly. More detaileddescriptions can be found in subsequent sections.

Text character Control character

Before entering the character Select the text number for which youwish to enter text.

Before entering the character Position the cursor under the textcharacter for which you wish to enter acontrol character.

Activate the function Enter text (F1) or activate the text window with the mouse if it is not already activated.

Activate the function Control character (F1) or activate thesequence window or the controlcharacter window with the mouse.

Entry is made Via the keyboard.

Entry is made By selecting the control character in thecontrol character menu with the mouse(click twice) or with the Cursor andEnter keys.

You can see the character entered In the text window.

9708b 2-15

Entering and deleting text

Use the cursor keys or the mouse to select thetext number for which you wish to enter ormodify text. You can then edit the text in theusual manner. You can delete a character withthe DEL key (Delete). The relevant controlsequence is then also deleted (see section2.2.4).

Entering and overwriting text characters

With the INS key (= Insert) you can switch fromthe insert mode to the overwrite mode and viceversa. You can tell which mode is active fromthe way in which the cursor is represented. Inthe insert mode it is represented as a rectangle;in the overwrite mode as a line. In insert modenot only the text characters but also the relevantcontrol characters are shifted to the right.

Text characters and control characters pushedout to the right will be lost.

In the overwrite mode you can overwrite textcharacters. Control characters, however, will notbe modified or deleted.

DEL

INS


2-16 9708b

Blank character (Tab character)

The blank character or Tab character is a specialtext character. When a new text is accessed inthe display, the positions at which a blankcharacter is transferred are not modified. The oldtext remains unmodified at these positions.

You can place texts one on top of the other,thereby forming a text out of several textnumbers (see following diagram).

The blank character cannot be used with alldisplay types.

Fig. 2/11: Superimposing texts


9708b 2-17

The diagram shows that some characters of thefirst text may then be overwritten (here letter Aby letter B).

If the display is deleted by a control characterand a text is then transferred, the blankcharacter will be represented in the same way asan empty space. However, you should use herethe blank character rather than the empty spacein order to save memory space. When a displayfile is created, all the display texts will be writtenwith the blank character (see Fig. 2.8).

Entering a blank character

If you wish to overwrite a text character with ablank/Tab character, activate function F7 Tabulatorcharacter. Control characters will not be modifiedhere.

F7


2-18 9708b

2.2.4 Control character mode

You can enter control characters in this mode.Their scope and performance depend on thedisplay used. The following editing functions canbe used in this mode:

– Enter or delete a control character or controlsequence (several control characters) for atext character.

– Modify a control sequence by inserting ordeleting control characters.

Control sequences can also be deleted in textmode.

Entering control characters

First place the cursor in text mode at the positionin the text file for which you wish to enter ormodify control characters. Now activate the function Controlcharacter (e.g. with F1). Then select the controlcharacter in the control character window.

Depending on the type of display, this windowshows at first only a few of the control characterspermitted for this display. By paging or scrollingwithin this window you can see the other controlcharacters.

F1


9708b 2-19

When you have selected a control character, itwill be shown in the control sequence window. Inthe case of control characters which require anadditional numerical specification, an entry fieldopens up in the sequence window (see followingdiagram).

The permitted value range for the entries can beseen in the control character window. You canconfirm your entry with the Enter key.

When a control character is entered, the relevanttext character, that is the text character at thecurrent cursor position, will be marked in colour.The way in which this happens depends on thetype of monitor used, as shown in the followingtable.

Fig. 2/12: Entry field in the sequence window

If you delete a text character marked in colour,the relevant control characters will also bedeleted.

You can enter several control characters foreach text character or for each cursor position.The amount is limited by the size of thesequence window and depends, therefore, onthe length of the individual control characters.The control characters are separated from eachother by a slash (/).

The cursor position has a bright background. Ifthe sequence window is filled with controlcharacters, you cannot enter any control charac-ters for the current text characters.

Fig. 2/13: Control sequence


9708b 2-21

Modifying the control sequence

Position the cursor in text mode at the textcharacter for which you wish to modify thecontrol sequence. The control sequence canthen be seen in the sequence window (see Fig.2.11).

Then activate the function Control character. Youcan now modify the control seqquence with thekeyboard or with the mouse, as shown in thefollowing table.

2.5 Loading the display RAM via the RS232 (V24) interface

In order to load a display file into the RAMmemory of the display, you should make thefollowing preparations:

– Connect the PC and the display with asuitable cable. Further instructions on thechoice of cable can be found in Chapter 1and Appendix B.

– Check that the communication settings of theFST software and of the display correspond.

– Some displays require appropriate switch orjumper settings for loading the texts. (Seehardware descriptions for the displays andAppendix B).

– For saving the display texts (external texts),some displays require a memory extensionmodule (e.g. E.ABG-1).

Activate the function Load display RAM (V24) inthe function selection. You then come to the filemenu in which you can select the file you wishto load. The interface selection then follows (seediagram below).


9708b 2-31

By activating the appropriate entries, you can setone after the other the address of both theinterface and of the configuration which you areusing. The interface configurations which youhave selected are then shown on the screen(current interface configurations). When youactivate the function Load text, loading starts.

The interface configuration selected here must correspond with the setting on the text display.Please make sure that the text display is in theprogramming mode (see manual for text display).

Fig. 2/20: Interface selection


2-32 9708b

Loading procedure

Various status messages are shown during theloading procedure. With the E.ABG-1 (EL, LED,VF) and E.ABG-80-EL additional messages alsoappear on the display.

2.6 Programming EPROMs

The display editor supports the programming ofEPROMS for saving display texts.

General information

The programming of EPROMs is a two-stageprocess. First of all, the display files areconverted into an Intel-hex format file. Thecontents of this file are saved in the EPROMwith the aid of an EPROM programmer. Thisprocedure is also known as "programming."

Programming requires special software which issuited to the programmer. Some commonmodels are supported directly by the displayeditor.

In addition, almost all EPROM programmerssupport files which have been created in Intel-hex format. These files can be created with thedisplay editor and loaded into the EPROM withthe aid of the software of the EPROM pro-grammer.


9708b 2-33

There are two procedures for programming theEPROMs for displays:

– Procedure 1 (for all ABGs with EPROM)Programming the EPROMs for all displayswhich support this procedure (including 8kEPROMs for displays E.ABG-EL, -LED, -VF).These EPROMs are programmed with thefunction Load EPROM in the main menu ofthe display editor (FST202C: also possible viathe menu Utilities).

– Procedure 2 (for E.ABG-1)Programming so-called OEM mode EPROMsfor the displays E.ABG-EL, -LED and -VF.The texts for the display and the operatingsystem of the display are combined in a 32kEPROM.

This combined file is generated with thefunction EPROM utility ("ABG-EL/VF OEMEPROM Utility Program" as from version 7/97– V.8 – integrated in the display editor). Startthe program in the display editor of theFST200 (key F3 EPROM utility). You canaccess further help texts with key F9.F9

F3


2-34 9708b

Programming EPROMs – procedure 1

If you activate the function Load EPROM in thedisplay editor or (only FST202C) under Utilities,the file selection will appear on the screen.Select here the file which you wish to save in theEPROM. When the selection is made, the file willbe converted into a data format which thedisplay can understand.

You can follow the conversion process through awindow in which the converted text numbers arecontinuously shown.

When the conversion process is finished, you willsee the following on the screen:

Fig. 2/21: Following the conversion process


9708b 2-35

The name of the active project and the currentinterface configuration is shown in the lower halfof the screen. With the aid of the functionsrepresented you can:

– specify the type of EPROM programmer (F1),

– configure the interface used on your com-puter (F2),

– select the EPROM type (F6),

– start the EPROM programmer (F4),

– return to the function selection (F8).

Selecting the EPROM programmer

When you activate function F1, the followingselection window appears:

The FST software supports the EPROM pro-grammers DATA I/O, PROM1000 and SE4943. Ifyou use one of these programmers, you will notneed any additional software nor will you need tomake any settings on the EPROM programmer.The appropriate unit will be selected when thisentry is activated.

However, please make sure that the specifiedinterface parameters correspond to the settingson the programmer.

Fig. 2/23: Selecting the programmer


9708b 2-37

Other EPROM programmers

You can use any other EPROM programmer,providing it operates with the Intellec-hex format.The last two entries in the window Programmertype serve this purpose.

Please read the operating instructions for theEPROM programmer completely through.

Intellec-hex dump

Your display file will be converted into theIntellec-hex format and output directly via theinterface specified.


2-38 9708b

Intellec-hex dump to file

If you activate this entry, your program will beconverted into the Intellec-hex format and into afile which you must name. Enter here a file namewhich gives information about the relevantdisplay file. You can then use the softwaresupplied with your EPROM programmer forprogramming the EPROMs and thereby accessthis file again. You can also enter a DOS devicename here (e.g. LPT1), in order to address theEPROM programmer via the parallel interface.

Selecting the interface configuration

If you activate function F2 Select Com-, you willsee on the screen a selection for determining theinterface and its parameters. By activating therelevant entries, you can set the addresses ofthe interface which you are using (COM1 orCOM2), followed by its configuration. The con-figuration which you select will then be shown onthe screen.

If your PC only has a serial interface, you mustfirst interrupt the connection to the controller andconnect the EPROM programmer to the sameinterface.

F2


9708b 2-39

Selecting the EPROM type

Before starting to program the EPROM, youmust specify the EPROM type which you areusing. To do this, activate function F6 or F7. Inthe centre of the screen you will see a selectionwindow with the possible EPROM types (seefollowing diagram).

PLEASE NOTEThe interface setting of the PC must corre-spond to the setting on the EPROM pro-grammer.

By activating the appropriate entry, you canselect the desired EPROM type. A new entry ismade on the screen immediately under EPROMtype.

2-40 9708b

Programming EPROMs

When you have made the necessary basicsettings for EPROM programming, you can startprogramming the EPROM.

Your PC must be connected correctly to theEPROM programmer. To do this, you require aspecial cable. The diagram in Appendix B showswhich pins are to be connected.

You can start the programming or burningprocess with function F4.

The data bytes transferred are counted up in asmall window. You can interrupt this procedureat any time by pressing the ESC key.

If transmission faults occur, then either theconnection to the EPROM programmer is faultyor the entries in the basic setting for EPROMprogramming are not correct. You can requesthelp with function F9.

If you have used one of the supported EPROMprogrammers, you can insert the EPROM intothe display as soon as the programming proce-dure is completed.

9708b 2-41

Programming EPROMs – procedure 2

The second procedure can only be used for thedisplays E.ABG-EL/-LED/-VF). These displayscontain their internal operating system on a 32kEPROM in socket U3 on the printed circuitboard. There is still sufficient memory space forthe texts in this EPROM. The texts for thedisplay and the operating system of the displayare stored together in this 32k EPROM.

If you have to provide a series with the sametexts, this variant has the advantage of beingmore rational and you can save the costs of apossible extension to the memory of the ABG.

On the other hand, creation and modification ofthe text files are less flexible. This procedure isnot, therefore, to be recommended, e.g. duringcommissioning.

CAUTIONMake sure that you insert a faultlessly createdEPROM (operating system) in the socket ofthe ABG.The operating system on the EPROM controlsthe microprocessor of the ABG. Faulty or un-suitable EPROMs can cause irreparable dam-age to the display.


2-42 9708b

Proceed as follows:

1. Create all the display texts for your projectand save them.

2. Connect the ABG to the PC and make surethat:- you are using suitable cables and that- the interface parameters are set identically

on both sides.

3. Switch on the display.

4. Activate function F3 EPROM Utility in the dis-play editor. The following will appear on thescreen.

5. Set the appropriate interface parameters onyour PC with key F3.

You can access further help texts with F9.

6. With F2 select the display file which you wishto save in the ABG.

Press key F1 to generate the file for theEPROM.The following process consists of the followingsteps:

– the display text is compiled (OBJ file);

– the operating system of the display is readand saved on the hard disc;

– these two files are combined and saved onthe hard disc.

2-44 9708b

Whilst this is taking place, status messages areshown on the screen. If the process is success-fully concluded, an appropriate status messagewill appear in the status line.

The completion message contains the followinginformation:

– the DOS path in which the new file is stored,

– the file name of the new Intel-hex file (*.32k)

The EPROM for the ABG can now be pro-grammed with this file and inserted in theappropriate socket of the ABG. Please observehere the instructions in the ABG manual.

CAUTIONMake sure that you insert a faultlessly createdEPROM (operating system) in the socket ofthe ABG. The operating system on the EPROM controlsthe microprocessor of the ABG. Faulty or un-suitable EPROMs can cause irreparable dam-age to the display

The creation of the software modules for linkingthe display and operating units depends on thetype of module. A distinction can be madebetween four different types according to theirmethod of operation.

– Display driver, texts stored in the SF 3

– Display driver, texts stored in the display

– Keys/keyboard driver (input driver)

– General driver for character input/output.

If you wish to enter and output texts, you mustusually create at least two software modules foryour ABG (one display driver and one keyboarddriver). The following table shows the function ofthe software module to be incorporated andwhere you can find further information on how tocreate the module.

3.1 General data for module creation

When creating software modules, you mustmake some specifications concerning the con-figuration. These are mostly operands which areused by the module, but also settings forsequence control.

Whilst the module is being created, the specifi-cations are interrogated in a window (seefollowing example):

Create the necessary software modules:

• with the display editor (chapter 3.2) or

• via Include module (chapter 3.3).

Fig. 3/1: Parameter entry during module creation (example)


9708b 3-5

The following specifications are typical and areinterrogated during the creation of most softwaremodules:

Edge detection

If the edge detection is activated, the softwaremodule will suppress the output of the sameconsecutive texts.

The edge detection has no effect if a variable isoutput together with the text.

The edge detection can be activated/deactivatedwith the following entries during module creation:

– 0 deactivate or

– 1 activate.

Sign detection

Sign detection is only of importance for theoutput of variables. It is determined via thestatus of the flag specified when the module iscreated. If its logical status is:

– 0, no sign is output. The variable value thenlies in the range 0 to 65535

– 1, we require one extra output column for thevariable output, because the sign is output aswell. The variable value then lies in the range-32768 to +32767.


3-6 9708b

Output delay

Time delay which must elapse before eachcharacter is output. It ensures reliable operationof the display (recommendation for E.ABG-2:1 ms).

Operands (flags, registers, timers)

Further specifications, e.g. about the flags andtimers used by the module, depend on therelevant module. Information on this can befound in the description of the relevant module insections 3.2 und 3.3.

The specified operands are entered in theallocation list.

Check in the allocation list before creatingthe modules to see which operands oroperand ranges are still free.

PLEASE NOTENo error message is shown if the entries inthe allocation list cannot be made correctlywhen the modules are created. You musttherefore check the error list for the createdmodule (function Show error list).


9708b 3-7

3.2 Creating the module with the display editor

The standard mode (texts in the SF 3) isintended mainly for text displays without textmemory. but can also be used for some displayswith their own text memory. A software module(CMP/CFM) must be generated from a MAK fileand from the display file (text) for this operatingmode. The software module is loaded into theSF 3. When the module is accessed, the text istransferred to the display (see chapter 4).

Fig. 3/2: Creating modules with the display editor


3-8 9708b

This procedure can be used for the followingMAK files:

– 3FD_XABG.MAK / 3FD^XABG.MAK

The MAK file must exist in the \LIB directory forthis purpose. The MAK files described in thismanual are automatically incorporated when theFST200 software is installed. Other MAK filesmust first be imported into the library directory\LIB with the function Import file.

Creating CMP/CFM

1. Activate the project for which you wish to cre-ate texts (function Select project).

2. Start the display editor of the FST200.

3. First decide whether you wish to create a pro-gram module or a function module(CMP/CFM) by using key F1 to select the ap-propriate entry in the starting menu of the dis-play editor. The function which is currently setwill be shown in the message line.

4. Then activate function CMP (or CFM) Gener-ate function CMP/CFM for standard mode.You will then see a file selection menu con-taining all the display files/texts of the activeproject.

F1


9708b 3-9

5. Select the file which you wish to incorporatein the module. Further specifications are thenrequired.

6. Specify in which CPU and with which numberthe module is later to be accessed (alwaysCPU number 0 for the SF3 control block).

Select a non-assigned number between 0and 15 for program modules; a number be-tween 90 and 99 for function modules.

7. Then activate the function Translate (F1).

If a module with the specified module dataalready exists, the following question will appearon the screen:

Fig. 3/3: Entering module data

3-10 9708b

Module xx/ZE0 (or function xx/ZE0) alreadyexists in the project directory.

Overwrite? (Y/N)

Yes The module will be created further. The already existing module will be overwritten.

No Module creation will be aborted. You thenreturn to the function selection.

You can follow the conversion process by meansof a window in which the text numbers arecontinuously shown.


9708b 3-11

Parameter entry for creating a module

The parameters to be specified depend on thetype of module. Make sure that the operands arenot already assigned in the allocation list. Youmust specify the following when creating thesoftware module:

• 3FD_XABG.MAK / 3FD^XABG.MAK"Display driver ABG, texts in SF 3 (internaltexts)"

+-----[FST V3.2 display driver ABG, internal texts]----+| With edge detection? (1=Yes/0=No) : 1 || Activate sign detection with flag : F 00.00 || Module transmitting text (Busy) : F 00.01 || Character output delay in ms (0,1,2) : 0 |+---------------------------------------------------------+

Parameters to be entered:

– edge detection (see chapter 3.1)

– sign detection (see chapter 3.1)

– module transmitting text; this flag is set by themodule providing texts or variables are sentto the display

– output delay (see chapter 3.1).

When you have entered all the parameters,activate the function Execute (F1). This con-cludes the module creation and you can nowload the module into the controller.

The parameters with which the module can beaccessed in the program are described inchapter 4.

3-12 9708b

3.3 Creating a module with the function Include module

By means of the function Incorporate module inthe FST software, you can create the followingsoftware modules from the MAK files in thedirectory \LIB:

– Display driver, text in the display (externaltexts)- 3FD_216S.MAK / 3FD^216S.MAK- 3FD_240S.MAK / 3FD^240S.MAK

– Keyboard/input driver- 3_EABG.MAK / 3ÊABG.MAK- 3_EABG2.MAK / 3ÊABG2.MAK- 3_ABG80.MAK / 3ÂBG80.MAK

– Driver for general character input/output viathe diagnostic interface (multi-communica-tion modules)- 3_ETMV5.MAK / 3ÊTMV5.MAK

– Other modules (32-bit arithmetic, driver forPCS operating consoles, see Appendix A)

The appropriate MAK file must exist in the \LIBdirectory for this purpose. The MAK files de-scribed in this manual are automatically incorpor-ated when the FST software is installed. OtherMAK files must first be imported into the \LIBdirectory with the function Import file.


9708b 3-13

When the module is accessed, texts andvariables are transferred to the display (seechapter 4).

Please note:Display drivers for texts in the SF 3 (internaltexts) must be created with the display editor(see chapter 3.2).

If display drivers are used for RAM, EPROM andfield bus modes (texts in the display), the displaymust have sufficient memory space and asuitable interface. You can create the display filein this memory with the aid of the display editor(see chapters 2.5 and 2.6). The texts are then inthe display.

You can transfer the texts from the text memoryinto the display by accessing the text numberswith the aid of the appropriate software module.

Creating CMP/CFM

1. Load the project/program for which you wishto create texts.

2. Start the display editor of the FST200.

3. Activate the function Include module in theproject management. The selection of MAKfiles in the directory \LIB then appears.


9708b 3-15

4. Select the MAK file with which you wish tocreate the software module. You can activatethe desired entry by clicking twice with themouse or by positioning the bright back-ground and pressing the Enter key.

Specifications on using the new module are thenrequested in a window.

Fig. 3/5: Include module (selection)


3-16 9708b

5. Enter under Prog./Module, whether a programmodule (B) or a function module (F) is to becreated with the MAK file selected.

6. Enter a free number for the software module.Depending on the type of software module,this must lie between 0 and 15 (CMP) or be-tween 90 and 99 (CFM).

7. In order to create several versions, you canenter a number between 1 and 9. Under De-scription you should enter a description of thesoftware module, usually a comment on theMAK file.

Fig. 3/6: Specifications on the module


9708b 3-17

8. Activate Include (F1), if all the specificationshave been entered correctly.

If a module with the specified module dataalready exists, the following question will appearon the screen:

Module xx/ZE0 (or function xx/ZE0) alreadyexists in the project directory.

Overwrite? (Y/N)

Yes The module will be created further. The already existing module will be overwritten.

No Module creation will be aborted. You then return to the function selection.

The software modules use certain operands forparameter transfer. These are interrogated in awindow.

A description of the operands, which are re-quired for the special modules, can be found inthe following sections or in Appendix A.

4.1 General instructions on accessing modules

The software modules as display and keyboarddriver are accessed by a user program.

You should take the following into considerationwhen planning your user program system:

– lnitialization of the SF 3 (with function moduleCFM 0, delete internal operands)

– Initialization of the display

– Cyclic module access

– Entries in the allocation list

– Communication via special operands, regis-ters and flags

– Evaluation of error messages

The software modules for the display andoperation units available at present are accessedby a program. Communication is made viaregisters, flags and special function units (FUs).


9708b 4-5

4.1.1 Initializing modules or displays

When a control system is switched on, operandsusually assume random values. It is thereforenecessary to set all the operands to definedoutput values at the beginning of a controlprogram. This also applies to the par-ameters/operands of the software modules forthe displays.

For this reason, an automatic basic initializationtakes place the first time a software module isaccessed. If the operands of these softwaremodules are to be reset again later during theprogram sequence, this must be programmed viathe appropriate flags of the module.

With some displays, you can also reset thecomplete system by means of flags (e.g. ABG-2).


4-6 9708b

4.1.2 Cyclic module access

Important program functions should be carriedout regularly (cyclically). You should also monitorkeys to see if they have been actuated.

Recommendation.Access the appropriate software modules (inputdriver) cyclically, e.g. in organisation programP0. In this way you can be sure that, in the caseof displays without a keyboard buffer, the keysare reliably monitored to see if they have beenactuated.

In the case of displays with a keyboard buffer,you need only press the Return key andtransfer the value entered (e.g. ABG-80: up tofive positions) from the keyboard buffer.

CR


9708b 4-7

4.1.3 Evaluation of status flags/error messages

The software modules return status messages orerror messages via certain flags or specialoperands. These should be evaluated in youruser program.

There are three methods of interrogating errormessages:

– In terminal mode of the on-line mode via theCI- command interpreter:

– The following data are output when theerror number is interrogated with "DF:">DF=nn

|

|

Error number

– In on-line mode as clear text message:In menu "Display SF 3 information" via func-tion key F6 (error/diagnosis)

Example:

Error no. | Error description

-------------¤------------------------100 Incorrect number of

parameters

– In STL/LDR user program via evaluation ofthe return parameter.In the case of return parameter FU32 = 0,return parameter FU33 gives the error num-ber.

F6


4-8 9708b

4.1.4 Software modules and command interpreter

If the command interpreter (test system) is activewhen the module is accessed, the module will beexited immediately and the accessing programwill be processed further. No text is output,neither the keyboard buffer nor the key flags areupdated, nor are the key LEDs controlled.

The software module simply checks the par-ameters and, if necessary, enters an errornumber.

Before the RS232 interface (DIAG) (e.g. fordisplaying the texts) can be released, the testsystem must be exited with the command Exit("X"). You can switch back to the test system byentering "CTRL T."


9708b 4-9

4.2 Module as display driver, texts in the SF 3 (internal texts)

(e.g. for E.ABG-1, E.ABG-80-LED, E.ABG-2,E.FD-2/40S)

Method of operation

By means of the transfer parameters, thesoftware module receives the numbers of thetexts and, in some cases, any variable stored inthe module. The parameters can be transferredas constants or from multibit operands.

The module transfers all the texts and variablesto be displayed to the ABG. In addition, flagsand special operands are used for sequencecontrol (status of the transfer, type of repre-sentation, faults).

The software module is processed sequentially,i.e. return to the accessing program is not madeuntil the sending procedure for the output iscompletely finished. Other programs are notaffected, they continue to be processed cyclically.

Settings and operands

– Edge detection (see also chapter 3.1)

– Output delay (see also chapter 3.1)

– Entries in the allocation list:

The parameters can be transferred as constantsor from multi-bit operands.

The following can be output depending on theaccessing parameter:

– Only texts (max. 255 texts can be ad-dressed). When the pulse edge evaluation isactive, output of the same immediately conse-cutive texts is suppressed, thereby avoiding aflickering of the display.

– Texts together with unformatted data*) The output has 5 character positions (defaultvalue). The leading character is the emptyspace (default value).

– Texts together with formatted data*)

The output can be limited in the number ofpositions.

*) If the data is represented with a sign, a space is always reserved in front of the data for entering anypossible minus sign. When texts are output together with data, pulse edge evaluation is not effective.


4-12 9708b

Examples of application

Example 1Text output of text no. 10(output of a text specified via parameter 1)

THEN CMP 2 ’Display driver ABG,’Internal texts

WITH V10 "Text number 10

If edge detection is active, a check is first madeto see if the current text number is the same asthe last output text number. If this is the case,no new output takes place.

Example 2Text output together with data (unformatted)

THEN CMP 2 Display driver ABG, ’Internal texts

WITH V5 "Text number 5 - FESTOWITH V-123 "Value

Text no. 5 selected with parameter 1 and thevalue transferred to parameter 2 are then outputwith five character positions and a leading sign.By means of a cursor positioning sequence, thevalue can be placed in front of or in the text.


9708b 4-13

If the data is represented with a sign, a space isalways reserved in front of the data for enteringany possible minus sign.

Output according to example (sign flag set):

FESTO - 123

Example 3Text output together with data (formatted)


WITH V5 "Text number 5"- result:

WITH R0 "Value WITH V3 "Print width 3

"characters WITH V’0’ "Leading sign

You can specify the number of positions in theformatted data output in the 3rd. parameter. Ifthe number of positions is greater than specifiedin the 3rd. parameter, only "$" signs will beoutput. If the specification in the 3rd. parameteris greater than 5, the default value 5 will beentered without an error message.

4.3 Module as display driver, texts in the display

(e.g. for E.ABG-1, E.ABG-80-LED, E.FD-2/40S)

Method of operation

By means of the transfer parameters, thesoftware module receives the numbers of thetexts and, in some cases, any variable stored inthe module. The parameters can be transferredas constants or from multibit operands.

The module transfers the text numbers andvariables to the ABG. In addition, flags andspecial operands are used for sequence control(status of the transfer, type of representation,faults).

The software module is processed sequentially,i.e. return to the accessing program is not madeuntil the sending procedure for the output iscompletely finished. Other programs are notaffected, they continue to be processed cyclically.

The software module outputs the text numberselected with parameter 1 and any transferreddata word to the display via the diagnosticinterface.

Instructions on using any desired display orASCII terminal:A text number output corresponds to an "Escapesequence" or a 2-byte sequence and is com-posed as follows:

MAK file Text number output

3FD_216S.MAK/3FD^216S.MAK

<GS><Text no.><GS> = ASCI control character

‘GS’ (29 dec.)<Text-Nr.> = Binary value,

z. B. 65 dec.


<ESC><Z><Text-Nr.><ESC> = ASCII control character

‘Escape’ (27 dez.)<Z> = ASCII character ’Z’<Text no.> = 3 decimal positions

e.g. 075

1) Flags Fx.0 to Fx.15 and Fy.0 to Fy.3 are set when therelevant key is pressed and reset when the key is released.

2) Flags Fy.8 to Fy.15 and Fy.0 to Fz.11 are used forcontrolling the LEDs. If a flag is modified, the relevantkey LED will be switched on/off.

3) If the flag is set, the software module receives an acknowledgement for the status request (Fz.12) fromthe E.ABG-2 ( = O.K.). The flag must be reset by theuser program.

4) This flag is set providing a string is sent for the LEDUpdate.

5) When the flag is set, a status interrogation of the display is made. If the send order is accepted, the software module will reset the flag again. The statusrequest should not be cyclic, but timer-controlled.In this way the functioning of the display can be checked.

6) When the flag is set, the module is initialized:– the key flags are reset– the Init sequence is sent to the display, all LEDs

are switched off – the module-internal flags for pulse edge control are

reset– the flags for status acknowledgement and for LED

Update are reset. Initialization is carried out automatically:

– the first time the module is accessed– when the test system is exited (CI command "X")


9708b 4-33

Parameter transfer

There is no parameter transfer when the soft-ware module is accessed.

If the CI command interpreter (test system) isactive at the moment the module is accessed,the module will be exited immediately and theaccessing program will be processed further.The key LEDs are not actuated and the keyflags cannot be updated.

If texts/control characters are to be output on thedisplay, the driver 3FD_XABG.MAK or3FD^XABG.MAK must be used for this purpose.The display editor of the FST200 is required forcreating texts.

4.6 Multi-communication module

(for character input/output on any display)

Method of operation

The software module enables communication(character input and output) with any display andoperating unit via the RS232 interface (DIAG) ofthe SF 3. Communication is ensured by meansof various operands (e.g. flags, registers, func-tion units).

The method of operation of the multi-communi-cation module changes depending on the ac-cessing parameters and is described in detail insubsequent sections. The following methods ofoperation are possible:


4-36 9708b

Function Meaning

Text output A max. 54-character long ASCII sequence is output.The text is stored in the user program.

Variable output (unfor-matted/formatted)

Output of values from the user program with/withoutsign. No. of positions max. 5.

Control characteroutput

A sequence of max. 27 control characters (Hexformat) is output. The text is stored in the userprogram.

Value input for multi-bit operands (with/without timeout)

A value is loaded as hexadecimal or with max.five figures. The value is returned as hexadecimal, decimal (with/without sign).

ASCII character input(key codes or character strings)

A sequence of ABG key codes is loaded. Entry isconcluded with the return key (<CR>). Depending onaccess, two ASCII characters are returned in a register or up to 4047 characters in the special function units.

Display ABG-internaltexts

Access texts which are stored in the display (external texts).

The use of the functions and possibilities of this software module depend onthe circumstances of your display and operating unit. For further informationplease refer to the manual for your ABG.


9708b 4-37

The driver is processed sequentially, i.e. returnto the accessing program is not made until thesend procedure during output is concluded, oruntil input is completely concluded. Other pro-grams are not affected, they are processedfurther cyclically.

1) The timer monitors the value input for a variable. If the time selected by program is exceeded, the flag for timeout will be set and the software module exited.

2) The flag is set if the value input for a variable does nottake place within the preselected time. If there is a fault (timeout), the software module will be exited.

3) If the flag is set, the ASCII character input will be interrupted and return will be made to the accessing program.

4) When the flag is set, the characters are output withsign. Value range:Fx.y = 0 0...65535Fx.y = 1 -32768...32767

5) The last or the last two ASCII characters entered will be stored in this register; the last in the low byte, the last but one in the high byte.

Depending on this, a check of the permittednumber of parameters will be made. If there is adeviation, error message 100 will be shown.

The display editor of the FST200 is not requiredfor creating the texts and control characters tobe output. These texts and characters aredefined as a string parameter when the moduleis accessed and stored in the accessing pro-gram.

The parameters can always be transferred asconstants or from multi-bit operands.


4-40 9708b

Text output (input parameter P1 = 0)

Input parameter P2 = String parameter, maximum

54-characters long (any ASCII sequence in inverted commas)

Example:

THEN CMP 15 ’Text module V5 - SF 3 WITH V0 WITH ’Text output’

(optional)

Example:

THEN CMP 15 ’Text module V5 - SF 3WITH V1WITH R0 "Variable valueWITH V5 "Number of positions

WITH V32 "Leading sign (blank)

If more than two parameters are transferred, theoutput will be formatted.

The contents of all mutli-bit operands andconstants are permitted as variable values. Thevalue range is 0..65535 or -32768...32767,depending on the type of representation se-lected. If a form with signs is used, a space isalways reserved in front of the variable for apossible minus character.


4-42 9708b

In the 3rd. parameter, the number of positions inthe formatted data output can be specified(permitted range 1..5). If the number of positionsin the value is greater than that specified inparameter 3, only "$" characters will be output(format error). If the specification in parameter 3is greater than 5, default value 5 will be enteredwithout an error message.

The ASCII code of the leading characters can betransferred in parameter 4.

Default = empty space (ASCII code 32 dec.). Ifthe valid value range from 32 dec. to 126 dec. isnot reached or is exceeded, error message 104(error in parameter 4) will be entered.


9708b 4-43

Control character output (input parameter P1 = 2)

Input parameterP2 = string parameter, maximum 54

characters long, i.e. 27 hexadecimal characters long (any ASCII sequence in inverted commas)

Example:

THEN CMP 15 ’Text module V5 - SF 3WITH V2WITH ’080A0D’

The control characters transferred as a stringparameter must be entered in hex-format coded,i.e. two consecutive ASCII characters aregrouped together before being output via thediagnostic interface and interpreted as a controlcharacter (valid value range "0" to "9" and "A" to"F"). The resulting control character sequence inthe example would then be <BS><LF><CR>.

If the sequence is not valid, error message 102"Error in parameter 2" will be output and thesoftware module will be exited.


4-44 9708b

Value input for multi-bit operands without ti-meout (input parameter P1 = 3)

Example:

THEN CMP 15 ’Text module V5 - SF 3WITH C3 "Value input without

"timeout

The value input can be hexadecimal (prefixed "$"sign) or a number with max. 5 figures with/with-out sign (prefixed "-" sign for negative numbers).

Value range:- hexadecimal numbers $0...$FFFF- negative numbers -32768...32767- positive numbers 0...65535

Valid characters are reflected (echo), controlcharacters are suppressed.

If the maximum number of characters is ex-ceeded or if invalid characters are entered, thesoftware module will be exited and the returnparameter FU32 <> 0 will show an invalid result.Entry is concluded with the Return key (<CR>).

A valid result is recognized via status message0 in return parameter FU32, the value itself issupplied in FU33.

CR


9708b 4-45

Value input for multi-bit operands with timeout (input parameter P1 = 4)

Example:

STEPTHEN LOAD V3000 ’Time specification 30s

TO TP15 ’Input timeout ’timer pre.

STEP loopIF NOPTHEN CMP 15 ’Text module V5 - SF 3

WITH V4 "Value input with "timeout

LOAD FU32 TO R0LOAD FU33 TO R1

IF F15.0 ’Flag timeout-Stat.-E.THEN JMP TO timeoutOTHRW NOP

This value input has time monitoring. The timerdetermined in the configuration is used here (e.g.timer 15).

The timer is started automatically when themodule is accessed. Only the timer preselectvalue needs to be specified. If the entry is notconcluded with Return key <CR> before the timeset with the timer preselect has expired, thetimeout flag will be set and the software moduleexited. The result is then irrelevant.

A valid result is recognized via status message0 in return parameter FU32, the value itself issupplied in FU33.

CR


4-46 9708b

ASCII character input (input parameters P1 = 5)

Loading ABG key codes

Example:

THEN CMP 15 ’Text module V5 - SF 3 WITH V5 "load ABG key enc.

IF R15=K$4B32 "F.-key F2 pressed?THEN NOPOTHRW PW

For loading the ABG key codes, you can enter asequence of ASCII characters when the modulehas been accessed. The characters are notreflected (no echo). The entry is concluded withthe Return key <CR>. The last or last two ASCIIcharacters entered are stored in the registerdetermined when the module is configured (thelast in the low byte, the last but one in the highbyte).

The software module can be prematurely exitedif the abort flag is set (determined during theconfiguration of the module).

Loading ASCII character strings

Input parameter P2 = 48...4095 Number of special operands P3 = 1....4047 Abort after specified number of characters (optional)

CR


9708b 4-47

Example:

THEN CMP 15 ’Text module V5 - SF WITH V5 "Read ASCII sequence WITH V3000 "Basis address

"special FU WITH V10 "Abort after 10 char.CFM 3 "Read special operand WITH V3000 "Request number

"of char.IF FU33 "With active

"test system= V0 "Repeat access

THEN PW

The 2nd. parameter in the access is interpretedas the basis address in the special operand field,as from which the number of currently receivedcharacters and finally the characters themselvesare stored. A special operand (low byte =character, high byte = 00h) is assigned here foreach character received.

When the module is accessed, the charactercounter is initialized with 0. The charactersreceived are not reflected (no echo). The entryis concluded either with <CR> (Return key) orwhen the number of characters to be received asspecified in parameter 3 is reached (optional). Ifan invalid special operand number is entered,error 102 "Parameter 2 incorrect" will be shown.

CR


4-48 9708b

You can still abort the module prematurely bysetting the abort flag (determined during theconfiguration of the module).

However, no abort takes place if the operandlimit (FU4095) is reached before the maximumnumber of characters is received.

The last or the last two ASCII characters enteredare stored in the register determined during theconfiguration of the module (the last in the lowbyte, the last but one in the high byte).

Display ABG internal texts (input parameter P1 = 6)

Example:

THEN CMP 15 ’Text module V5 - SF 3 WITH V6 WITH V1 "Text number

The number of the text, which is to be displayedand which is stored in the ABG, is transferredwith the 2nd. parameter. During access thestring dh 01h is sent via the diagnostic interface.No check is made of the specified text number.


9708b 4-49

Remarks

The software module can be accessed simulta-neously from several programs, providing thevalue (function) transferred with P1 is different.

Example: Program P0 outputs text (P1 = 0) andprogram P5 waits for an ASCII charactersequence (P1 = 5) to be input.

If this cannot be assured, either locking must beimplemented by means of flags or the programsmust use different software modules for theiraccess.

By means of the following functions, the FSTsoftware supports user-friendly commissioning ofthe SF 3 with a display and operating unit:

– Display emulators (for texts in the SF 3 aswell as keyboard entries) and

– Display test (for texts in the ABG).

In this way you can simulate the function of theABG on your PC or check the texts stored in theABG.

This chapter also contains practical tips on howto make commissioning easier.


9708b 5-3

5.1 Commissioning with display emulators

During commissioning, the PC is connected tothe SF 3 control unit via the serial interface inorder that programs can be loaded and that theprogramming sequence can be followed. Ifnecessary, you must also check or modify thecontents of single-bit or multibit operands.

If the system is to be operated with an ABG, youmust switch frequently from ABG to PC (or bymeans of a switching box).

This procedure is possible and practicable withall ABGs, but not very user-friendly. Emulatorshave therefore been designed for the mostcommon ABGs from Festo.

At present, the FST200 contains three emulatorsfor the display and operating units E.ABG-1,E.ABG-2 and E.ABG-80-LED from Festo. Theseemulators form the relevant ABG on the screenof your PC.

You can connect the PC to the RS232 interface(DIAG) of the SF 3 during commissioning and atthe same time:

– load and test user programs and

– show all the texts in the SF 3 (internal texts)on the screen via the emulator and interro-gate keyboard entries.

Information on the scope of the ABG functions isincluded with the relevant display.

Fig. 5/2: User-friendly commissioning with the emulator

5.1.2 Installing the emulators

The emulators will be installed automaticallytogether with the FST200 on your PC.

The emulators are independent programs whichcan be started with the function Programexecution in the menu Utilities.

1. First select your project.

2. Then start the emulator which is suited toyour ABG with the function Program accessin the menu Utilities.

Only one emulator can be started at one time.

Fig. 5/3: Accessing the emulator (example)


5-6 9708b

The emulator is now loaded into the memory ofthe PC ("memory resident") and can be startedwith ALT+ F10. Memory resident programsremain in the memory of the PC until they areremoved explicitly.

When an FST session is concluded, the loadedemulator must be removed from the memory.This takes place automatically as from version3.2 – revision 8 – 8/97 of the FST200 software.In order to display the version of your FSTsoftware, press key F10 in the main menu. Theversion will then be shown in the status line (e. g.3.2-0008 01.08.97).

For earlier versions or in order to remove theemulator without terminating the FST software,you can enter or execute the commandEABG1N-U:

– with the function Configuration (under program termination),

– or with the function Program execution.

5.1.3 Accessing and exiting an emulator

When you have installed an emulator and startedit via the program access, you can access it orsuperimpose it at any time from the background.You can access the memory resident emulatorwith the key combination ALT+F10, whereuponthe relevant ABG will appear on the screen.During this time the other FST functions areblocked.

– Access emulator: ALT + F10

– Exit emulator: ESC

All the text outputs of the SF 3 are now shownon the PC screen of the ABG display. Entriescan be made via the PC keyboard. These entriesare transferred to the SF 3 (according to thecurrent user program).

When you have completed your entries, you canexit the emulator with ESC. All the FST functionsare then available again.

PLEASE NOTEDo not exit the emulator with ESC while theprogram is outputting texts on the display, ascommunication with the test system may bedisturbed. If this does occur, exit the test system with F8and access it again immediately. Communica-tion will then be restored.

Remarks and tips

When the ABG is accessed, it appears in the topright-hand corner of the screen. You can movethe superimposed ABG across the screen bymeans of the cursor keys. This information isretained during an FST session.

When the emulator is activated, it stores some ofthe FST software on the hard disc. Approxi-mately 300 kB memory space is required for this.When the emulator is exited, the program partsare reloaded into the work memory.

The operating system of the SF 3 processescommands of the command interpreter beforeprogram-controlled inputs and outputs. When anemulator is accessed, all the other functions ofthe FST, including the command interpreter, willbe blocked.

The emulators exchange the desired data withthe SF 3 via the RS232 interface. The PC reactslike the corresponding ABG and communicateswith the active software module (display/key-board driver) of the user program.

5.3 Practical tips

– Plan the software modules for display andoperation in the user program system fromthe beginning.You then avoid conflicts with module numbersand entries in the allocation list.

– When accessing the software modules, takeinto account that the cycle time increases dueto the time required for entering and output-ting characters (reference value approx. 1 msper character). Observe this especially whenyou access the module from program 0 (orfrom the main program).

A-22 9708b

The display editor of the FST200 is not necess-ary for creating the texts and control charactersto be output. These are defined as a stringparameter when the module is accessed and arestored in the accessing program.

The parameters can always be transferred asconstants or from multi-bit operands.

Remarks

The software module can be accessed fromseveral programs at the same time, providing thevalue transferred with P1 (function) is different.

Example:Program P0 outputs a text (P1 = 0) and programP5 waits for the input of an ASCII charactersequence (P1 = 5).

If this cannot be guaranteed, a locking must beimplemented by means of flags or the programsmust use different software modules for theiraccess.

Drivers for PCS operating consoles (only in conjunction with PCSPRO planningsoftware)


It is used for operating a parametrized PCSoperating console (parametrizing with PCSPROplanning software from Lauer) at the RS232interface (DIAG) of the SF 3 control block.

The software module is used as a connection tothe PCS during a new start or after interruptionin communication. It also controls the exchangeof data between the parametrized data field ofthe special operands of the SF 3 (256 words)and the task packages of the PCS received viathe serial interface.

Operands

The following operands are used internally in themodule and must be specified during configura-tion of the module.

Number of repeats (1..255)If an incorrect data package is received, the datawill be requested again. Specify the maximumnumber of requests (1..255). When a correctdata package is received, counting will start fromthe beginning. If the maximum number ofrepeats is exceeded, there will be an interruptionin communication.

Timeout (0.6 s bis 2.55 s)During communication of the PCS with the SF 3,there is a continuous exchange of data. Thetimeout time is the monitoring time betweensending the reply telegram from the SF 3 andreceiving a new task package from the PCS.The input value can be selected between 60 and255.The timeout time is calculated from this: i.e. inputvalue x 10ms, so that times between 0.6 s and2.55 s can be specified (default value 0.6 s).If there is an error (timeout), a restart must becarried out.

Description

The configured software module has beendesigned for both initialization and the cyclicexchange of data with the PCS operatingconsole. The different methods of operation aredetermined by the parameter transfer (seeParameter transfer). As regards data exchange,the PCS operating console is the master; the SF3 is the slave. The operating console sendsorders (task packages) to the SF 3 whichprocesses them and sends back replay data tothe PCS.

In order to maintain this exchange of data, it isnecessary to access the software module cycli-cally. Only at the start of communication is theSF 3 the master. It sends the reset telegramwhich opens communication after a restart of theSF 3 or after an interruption in communication.

The task packages are formulated by the PCS,whereby the necessary operations (write, read,or and and) refer to the configured range of thespecial operands. The actually necessary data istransferred, whereby the amount of data isreduced.

The software module is exited again immediatelyafter each access, in order that the accessingprogram can be processed further.

Parameter transfer and error messages

The configured software module permits twotypes of access:

Remarks

If you create the software module for the 32-bitarithmetic from a MAK file which was suppliedwith FST200 software before version 3.2 -revision 8 (at at 8/97), the overrun is not outputin FU32 (<> 0) during addition. Therefore FU35must be checked here.

Workaround: Instead of the missing output of the overrun, anoverrun can be ascertained by evaluation of thereturn parameter FU35.

FU35 = 0: No overrunFU35 <> 0: No overrun

Error messages

Due to their briefness the error messages of thedisplay editor cannot give detailed information onthe causes of errors and how to rectify them.The error messages have therefore been listedalphabetically in this section with individualexplanations. These give instructions on thecauses of the errors and how to rectify them.

Display file is empty

CAUSE: You have activated a function (e.g. burnEPROM) which is of no significance for the fileselected as it has no contents. You haveprobably selected an incorrect file.

REMEDY: Select a different file.

File too long. Delete something.

CAUSE: The display file which you have createdrequires more memory space than the memorycapacity allowed by the display for which it wascreated.

REMEDY: Delete superfluous texts or controlcharacters.

Filename may only be used as a function module.

CAUSE: You wish to create a program modulefor standard operation (create CMP). The fileselected was created for a display which doesnot permit this operating mode.

REMEDY: After activating the function CreateCMP, select a file which was created for adisplay which permits this operating mode.


B-8 9708b

Invalid field bus address.Value must be 2 or 4.

CAUSE: You have specified a non-permittedaddress for the field bus module.

REMEDY: Only the addresses 2 or 4 arepossible. Enter 2 or 4.

Invalid field bus participant address. Range is 01 to 99.

CAUSE: You have entered a non-permittedslave number for the display.

REMEDY: Only one slave number in the range1 to 99.

Load display RAM via field bus not possible with this display.

CAUSE: After activating the function Load dis-play RAM (field bus) you selected an incorrectfile. This file was created for a display type withwhich loading via the field bus is not possible.

REMEDY: Select a file which was created forfield bus operation.

Load display RAM via V24 not possible with this display.

CAUSE: After activating the function Load dis-play RAM (V.24) you selected an incorrect file.This file was created for a display type withwhich loading via the V.24 interface is notpossible.

REMEDY: Select a file which was created for adisplay with V.24 interface.


9708b B-9

MAK file does not available.

CAUSE: You want to create a module. Thedisplay driver required for this (*.MAK) is not inthe library directory (LIB).

REMEDY: Import the required display driver intothe LIB directory.

MAK file not installed

CAUSE: You want to create a module forstandard operation. The display driver requiredfor this (*.MAK) is not entered in the library file(ANZED.BIB). Either standard operation for theselected display type is not possible or the driveris not yet available at the time of softwarecreation.

REMEDY: Check whether the current version ofthe display editor is installed in your computer.Perhaps you have simply selected an incorrectfile during module creation.

Module ?? / CPU ? already exists in the project directory. Overwrite?

CAUSE: When creating the module, you se-lected a module and CPU number which alreadyexists.

REMEDY: Enter Y if you wish to overwrite theexisting module. OR: Enter N for No and selecta different module or CPU number.


B-10 9708b

No display files available.

CAUSE: You have activated a function which isfollowed by the file selection (e.g. Delete file).However, the active project does not contain anydisplay files. File selection cannot therefore beoffered.

REMEDY: Check whether the correct project isactive. OR: Create a file for the current project.

Project does not exist.

CAUSE: You have started the display editorwithout activating a project in the FST software.The display editor must know the project forwhich you wish to create display files.

REMEDY: Select a project with the FST softwareor create a project.

Text exists already. Overwrite ?

CAUSE: You want to copy a marked text into atext number for which text already exists.

REMEDY: Enter Y for Yes if the text is to beoverwritten. OR: Enter N for No in order to stopthe copy procedure.


9708b B-11

The file specified is not a FESTODISPLAY FILE

CAUSE: Every display file receives a mark. Youhave selected a display file (*.ANZ) in which thisnecessary identifier cannot be found. The file isprobably damaged.

REMEDY: You can only remedy this if you arefamiliar with the operating system. As a safetycopy with the file extension ".BAK" is storedwhen a display file is saved again, there isprobably also a safety copy of your damagedfile. Delete the damaged file with the aid of theoperating system.

PLEASE NOTE If you delete the file with the display editor, thesafety copy will also be deleted. When the filehas been deleted, you can rename the safetycopy of the file with the aid of the operatingsystem. Give the file the same file name, butwith the file extension .ANZ. Check whetherthe desired function is possible with this file.


B-12 9708b

The last text overwritten (overrun). Insert anyway?

CAUSE: You want to enter a new text number inthe display file. All subsequent text numbersmust therefore be increased by 1. As text hasalready been entered for the maximum textnumber and the number cannot be increased,this text will be lost as a result of the insert.

REMEDY: Enter Y for Yes if you wish to inserta text number and if the text with the maximumtext number is to be deleted. OR: Enter N for Noand first delete a non-required text numberbefore you insert a new text number.

There is no project selected.

CAUSE: You have started the display editorwithout previously activating a project in the fSTsoftware. The display editor must know theproject for which you wish to create display files.

REMEDY: Select the desired project beforestarting the display editor.

Too many files

CAUSE: By creating a new display file, you haveexceeded the maximum permitted number ofdisplay files for the current project. You cannotcreate more than 127 display files.

REMEDY: Delete a display file no longerrequired from the current project before creatinga new file.


9708b B-13

Unknown display type

CAUSE: You want to work with a display filewhich was created for a display type which is notentered in the library file (ANZED. BIB). The filewas probably created on a different computer onwhich a later version of the library file is stored.

REMEDY: Install the version of the display editorwith which the display file was created.

You cannot burn an EPROM for this display.

CAUSE: After activating the function BurnEPROM, you selected a file which was createdfor a display which does not permit EPROMoperation.

REMEDY: Select a file which was created for adisplay which permits EPROM operation.


B-14 9708b

Definitions of terms

In the individual sections terms are often usedwhich are product-related and therefore notfamiliar to everybody. These terms are explainedin this section.

Baud rate (bits per second) The speed of transmission in the data transferbetween communicating systems. The baud ratespecifies the number of bits which can beetransmitted per second. Common baud rates are75, 150, 300, 600, 1200, 2400, 4800, 9600,19200 Baud.

Configuration The combination of various devices into asystem. When used with software these must beadapted to the system (configured), in order toguarantee reliable data communication.

Display driverDisplay drivers are rough modules. From theserough modules program modules arecreatedwhich permit text output. They are speciallyadapted to the operating mode and the hardwareconfiguration used.

Edge detectionA check which takes place before a text is outputwithout a variable. By comparing the text numberand the module number, a check is made to seeif the text to be output is the same as the lastoutput text.

EditorThe background program with which you createe.g. control programs or enter texts is refered toas the editor. An editor provides the necessaryfunctions and is adapted exactly to its task.


9708b B-15

EPROM (erasable programmable read onlymemory) A memory which can only be erased with UVlight and which is fault resistant. It can be writtenagain with a special programmer. With someFesto displays you have the possibility of usingsuch memory modules.

Field bus Serial bus system which connects physicallyseparated parts of a procedure or technicalmanufacturing process for the purpose of ex-changing information. Sensors and actuators canbe connected to decentralized stations in thisprocess.

Field bus module This enables field bus slaves to be connected toa control system.

ProgramA program is an individual control task in theFST software. Several programs can form aproject.

ProjectIn the FST software, a project is the groupingtogether of several programs and programversions with a higher-order documentation.When a project is created, the FST softwarecreates a directory. All programs and filesbelonging to the project are stored in thisdirectory.


B-16 9708b

RAM (random access memory) A memory with random access. Data stored insuch a memory can be read, modified anddeleted by computers. If the power supply isswitched off, all stored data will be lost unlessbattery backup is provided.

RS232 interfaceA standardized serial interface which can beused in many situations. It can be used e.g. toconnect a compuuter or a controller with periph-eral devices such as a text display.

Sign detection The sign determines the type of representationor the value range of variables when they areoutput. If the sign detection is activated, thevariable value will lie in the range from -32768 to+32767. If the sign detection is inactive, thevalue will lie in the range from 0 to 65535.

Window A window is a fixed limited range of the screenin which special instructions or messages areshown.
