1.FIX Overview

1.1 Capablities of FIX Software

Fix is true Client/Server i.e. no replication of dBs is required.

A. Introduction to FIX Software

Industrial Automation Software

Provides a Window into the process

Supplies real-time data to personnel and to software applications

Basic FIX functions are:

- Data acquisition

- Data management

A. Data Acquistion

Ability to retrieve data from the plant floor

Direct communication with I/O devices in the plant

Interface to the I/O devices via I/O drivers

B. Data Management

Ability to process and manipulate acquired data

Data management is made up of many components, including:

process monitoring (graphic display)

supervisory control

alarming

reporting

data archiving

1.2 Terminology

A. Node Types

A computer running FIX is called a node A node that acquires data from a process is a Scada serverSCADA -- (Supervisory Control and Data Acquisition)

communicates with process hardware via I/O driver software

loads and maintains the process database

A View Client is one that does not perform SCADA functions

this node receives data from SCADA nodes

A View node can run other application software

B. Node Configurations

Stand alone node

Any node not communicating with nodes on the network

Fig 1.1 shows a stand-alone SCADA server

Fig 1.2 shows a distributed process

Local node

describes the node being worked on currently

Remote node

On a distributed system, a node other than the local node

May also refer to a node being accessed via a modem

Run-Time node

Does not allow modification of displays or process database

Not necessarily read-only

PlantTV

A read-only View client with DDE and ODBC options

Fig 1.1: Example of a stand-alone FIX system

Fig 1.2: Example of a distributed FIX System

2 Basic Architecture of FIX

A.Process Data

FIX is used with the process instrumentation in a plant.

Sensors and controls send data to registers in the process hardware.

Typically this hardware is a PLC

Fix software acquires raw data from process hardware.

B.I/O Drivers

The FIX interface to a PLC is called an I/O driver

Each I/O driver is specific to the PLC hardware

I/O driver functions:

Read (and write) from the I/O device (called polling)

Transfer data to/from addresses in the Driver Image Table (DIT)

An I/O driver collects data from poll records

poll records are specified by addresses in PLC registers.

a poll record can be a single data point or a range of points.

C.Driver Image Table (DIT)

Area of SCADAs memory where the I/O driver stores poll records

I/O drivers update poll records in the DIT

Each poll record has a rate at which updates are processed.

Update rate is called the poll time and is default of 1 second

D.Scan, Alarm and Control (SAC)

SAC functions include:

Fetching data from the Driver Image Table (DIT)

Transferring data to the Process database (PDB)

SAC reads from the DIT at a rate called the scan timeDefault 1 second, minimum of 0.05secs (dont believe it)!

Fig 1.3: FIX architecture.

3Development Applications

A.Development applications used

The Draw application is the program used to develop pictures.

The View application is used for viewing the pictures

Database Builder is used to add tags to the Process database (PDB)

The System Configurator is used to set options within FIX (referred to as the SCU, pronounced skew)

Startup. (Used to start the Scada application)

Mission Control

Each of these is described in detail later.

4iFix versus FIX32

iFix ver 3.5 is the latest product from Ge-Fanuc and is used extensively throughout industry. iFix is different to Fix32 in that it uses VBA instead of the scripting language as used in Fix32, this makes iFix software a much more powerful tool for accessing and manipulating not only data and screens, but allows the user to actually write programs from within the iFix environment. The capabilities of the software are only limited by the user himself and inherent limits of VBA .The basic components of iFix, are however very similar. The Database builder is the same (very similar), the SCU is the same. The main differences are the Workspace view and the driver implementation. Alarming is the same.

IFix is in-line with latest technologies and uses objects extensively. It supports embedded externally written ActiveX objects within its own runtime window. This allows for extremely powerful solutions to be developed with the minimum effort and securely.

For the purpose of this document we are going to concentrate on FIX32 as it is a sound basis for understanding Fix and Scada applications. Fix32 is still the main workhorse of the Hot Mill Scada network.

New developments should consider moving to iFix as a solution within the Hot Mill.

5Varieties and versions of Fix32

FIX32 Scada Development.

The development package gives the user full access to all development tools to develop a total project up to the number of tags the software allows.

FIX32 Scada Runtime

This is the runtime version of the application as developed above.

FIX32 SuperScada

This is FIX32 Scada Development with every available option supplied.

FIX32 View Client Development

This is the development tool for View clients. Effectively only allows a user to generate/modify pictures. There is no access to the PDB or DIT. Allows reads/writes to a Scada node

FIX32 View Client Runtime

As above this is a runtime version of the View development.

PlantTV

This is a Read only version of the View client and does not require a Dongle. (software key Option Disk required).

Fix Dongles are supplied on the following basis: -

75 Tag.

300 Tag.

Unlimited.

The latest (last) version of Fix32 is version 7.0

Most of the Hot Mill is running Version 6.15, some systems have been upgraded to version 7.0

You should also be aware of SIMs (Software Improvement Modules). These are effectively service packs for Fix. Most identified problems can be related to a SIM pack and you should always check the GE_Fanuc website for the latest SIMs.

The Help desk for Ge-Fanuc are also a good source of information and help.

6Installing Fix32

FIX32 is supplied as standard on CD together with a Dongle.

To install Fix32 7.0 onto a machine you must be a local or domain administrator for the PC you intend to install it on.

Insert CD in CD drive, right mouse button on Icon My Computer on desk top, select explore and go to the Winsetup\install and run SETUP.EXE by double clicking. See Fig 1.3 below.

Fig 1.3 Running SETUP.EXE

After several Splash screens and licence agreements you should have this.

Select Custom Installthe next screen should show.

Select Fix Support, I/O Drivers and FIX Electronic Books.

You can select the sample system if you wish?

Installation starts as below: -

When complete, you will be prompted to add any other Scada nodes you wish to access from this node. You can add all the Hot Mill Systems if you wish. This is only required if you wish to display pictures off other nodes. This can be demonstrated later. For the purpose of this Demonstration add the SPRAYS node.

6.1Starting FIX

Start FIX by double clicking on Startup in main Fix menu.

(Note if there is no Dongle installed you will get the DEMO MODE only for 2 hours)

Now we are ready to Develop, well almost!

7 Developing displays

When you first startup Fix Draw is automatically started for you, this can be changed later if you want. It should look similar to this

The toolbox is configurable and can be modified from with Tool Box Setup under the Tools option in Draw.

For the purpose of Demonstration we are going to develop a Temperature display that will consist of a 2 Temperature bar indicators and a Trend display, to trend the 2 values.

Developing a simple screen

Go to File select New and use the Default template. Go to Edit, Picture and change the Background colour to something other than white, remember this is going to be the background colour of your picture.

From the Toolbox select the Rectangle object and draw/drag it as below -

Draw another Rectangle as below

Draw a Line and add some text

Add the Dynamic properties to the Rectangle by double clicking the temperature bar.

Select Vertical Fill and enter the following details

An alternative method is to use the ? and browse to the required tag. Select OK

Highlight all the selected area as below and Group the object by CTRL G.

Note: - Line limits at 650 min to 900 max.

Move this object into the original Rectangle. Add a Data Link Make this point to the same Tag as the temperature bar.

Modify the Numeric data for

Then OK, OK.

Finally group the whole object as one by highlighting all and selecting Arrange and Group or CTRL G.

As you will find out later there are many ways to carry out the same function.

To view the display, Right mouse button on the screen and select Quickview.

Right mouse and select Quickdraw to go back into edit mode.

Highlight the object and copy it CTRL C and paste it CTRL V, drag it to one side, ungroup it CTRL R and drag out the temperature bar. You will have to do this several times. Double click the temperature bar and re-click the Vertical fill button, this will display the Tagname and limit box again, go to the ? and re-browse the Sprays node to pick up another Tag, e.g. F7_TEMP. Modify the text to reflect the correct temperature scale. Re-group and move back to display and Group the whole object again.

Align the 2 temperature objects to the top and group. Add another rectangle and send it to the back of the temperature object using CTRL B. Centre it and Group.

The display should look similar that below

Adding a Chart object

Select the Chart object and place the stamper on the screen below the temperature object

Select the pen options button

Add the two temperature Tags to this object, use the Add button to put it into the Penbox

Note the limits have been changed to reflect the working values of the signals.

OK this.

Drag the object and change the objects background and forecolour, modify the axis at the same time, the display should look like (similar) to this

Add an Alarm Summary object -

Filter the Object to display the Sprays alarms only, for all priorities and disable the control border.

OK this.

The display should look like this.

Add a time and date object to the top of the display, modify colours to show as below

Save the picture as HMTEMPF7 using File and Save

Add a Button object to the bottom of the display .

Change the Button Text as below:

Double click the Edit Commands button and enter change it as below:

Use File and Save

Do nothing else at this point.

Your picture should be similar to this:

8 SCU (Systems Configuration Utility)

From Draw, Apps select System Configuration

From here the Scada can be defined, paths selected, Networking, Alarms, Security and Startup options are set.

Double click the Node text within the VDU Mimic and change the Node name to be SCADAx, where x is the number of your station.

I/O/DIT drivers can also be accessed and configured through this route. By default the SIM driver is embedded as standard.

The SIM driver is capable of generating Ramp, Sine, Random and Digital signals for Simulating inputs. A list of the SIM addresses are show below

8.1SIM Addresses

RARamps a value from 0 to 100% of the EGU range at a rate controlled by the RY register. Read only

RBCounts from 0 to 65535 at a rate of twenty counts per second.

Read only

RCShifts one bit through a 16-bit word at a rate controlled by the RZ register. Read only

RDGenerates a sine wave from 0 to 100% of the EGU range at a rate controlled by the RY register. Read only

REGenerates a sine wave from 0 to 100% of the EGU range at a rate controlled by the RY register. The sine wave is delayed 90 degrees relative to the RD register. Read only

RFGenerates a sine wave from 0 to 100% of the EGU range at a rate controlled by the RY register. The sine wave is delayed 180 degrees relative to the RD register. Read only

RGGenerates random values between 25% and 75% of the EGU range. Read only

RHRamps a value from 0 to 100% of the EGU range and then ramps down to 0% again at a rate controlled by the RJ register. Read only

RIControls the ramp direction of the value in the RH register. When zero, register RH ramps down; when one, RH ramps up. The value automatically changes when RH reaches 0 or 100% of its EGU value.

Numeric Value (0 or 1)

RJControls the ramp speed (in cycles per hour) for the value in register RH. The default value is 60 (1 cycle per minute).

Numeric Value (2 to 3600)

RKEnables or disables the generation of the value in the RH register. Enter zero to freeze (disable) ramp and a non-zero value to enable it.

Numeric Value (0 or 1)

RXEnables or disables the generation of values in the other registers. Enter zero to freeze (disable) all registers and a non-zero value to enable all registers.

Numeric Value (0 or 1)

RYControls the speed (in cycles per hour) at which new values are generated for registers RA, RD, RE, and RF. By default, the RY register is set to 60 (1 cycle per minute).

Numeric Value (2 to 3600)

RZControls the speed (in bits per minute) that the register RC changes its value. By default, the RZ register is set to 180 (3 bit shifts per second).

Numeric Value (2 to 1200)

All SIM registers support Analog Input, Analog Register, Digital Input, and Digital Register blocks. However, for best performance, use the following blocks with the following registers:

Analog Input

RA, RD, RE, RF, RG, and RH

Analog Output RJ, RY, and RZ

Analog RegisterRA, RD, RE, RF, RF, RH, RI, RJ, RK, RX, RY, and RZ

Digital Input

RB and RC

Digital RegisterRB, RC, RI, RK, and RX

NOTE: The RB and RC registers support Digital Register offsets of A_0 to A_15.

9Process Database and DIT

The process dB is used to reference Real names to the values that the DIT (Driver Image Table) collects.

The DIT is the driver interface to the outside world. This interface can be serial or networked. PLC registers are collected with the DIT and are then collected by the PDB where a real name is attached to the register. An example of this is N251, which is the Roll Change time in seconds; the PDB record for this is shown below

Actual Tag name is RCSEC

To start Database builder you can do this either from the folder or from Apps, Database Builder. It should look something similar to below

Go to Database and Open the SPRAYS node from the network list and OK this. (note: you should only see the SPRAYS as it was the only node that was added at install time).

On OK, the dB tags are recovered and copied to your local machine as below

Note at this point you are working on a local copy on your machine and the on-line dB is not affected until you either Save or exit the dB Builder where you are prompted to save your changes. However if you go in and edit a Tag, be aware that you will take the Tag off Scan. See example below.This is a snapshot of Database Builder before, (note the Scan Stat is ON)

Double clicking a Tag will open up the Tag display as below

Even if no edit is done to this Tag and you change nothing, OK or Cancel will move this Tag off Scan. This is confirmed with the Display as below

To put the Tag back on Scan, simply click in the Scan Stat field for the Tag and type ON. This changes the Tag to either ON or PON the PON simply means it is waiting for SAC to complete its scan and update the Tag status. Pressing CTRL R refreshes the database display.

To filter the Tags on the display, use the Query option and select the criteria you wish to filter by. You can also include * as a wildcard selection. An example is to find all occurrences of the string beginning with F7, i.e. any string that starts with F7 and anything after it.

Select Query, Edit Query and change it to the following

Enter OK after the filter has been applied you should end up with the following display

At this point go to Database and Close the view of the SPRAYS Node.

Go to Database and Open up your local node name = SCADAx

To add a Tag; as an example a SIM Tag for Register D i.e. SIM:RD, carry out the following. Select Blocks, Add, select AR (analog register) and OK. You should see as below

Modify the record to match as below, it should look like this

Enter OK.

Note that the Scan Stat is OFF this is normal for an Analogue Register!

Repeated presss of CTRL R updates the value dynamically on each press.

On exiting Database Builder you will be prompted to Save current Database options before exiting?, enter No, you will be further prompted to Save Changes to Database on Node: SPRAYS again enter No

After closing the SPRAYS dB, open up your own local dB add analogue SIM registers for RA to RH and Save this to your own dB. If prompted reload the dB, you will be warned that SAC is about to be stopped and prompted to continue or not.

Go to DRAW and develop a screen to display all the Tags as Data Links and Graphical information.

10 Historical Trending

In the earlier section whilst developing our first screen, we made use of the real-time trending object. You will have noticed that each time we went from Draw to View the chart was restarted each time. In the real world it would also be nice to see what has happened over a period of a day, week, month. etc.

This section discusses historical trending, which is used to obtain a copy of database values and reserve these values for later viewing.

Historical trending is done in three steps:

Historical Assign(HTA)

Historical Collect(HTC)

Historical Display(HTD)

10.1Historic Assign

a.Used to define the data archiving strategy

Defines the following:

Tagnames and fields to be collected

Rates at which the tag is collected

Digital tags that trigger any event driven collection

Duration of the historical files in hours

Number of days that files are to be stored on the hard drive

There can be up to 64 collection groups defined

Each group can have up to 80 tags

b.Data File Duration

Allows the user to save historical trend data in 4, 8 or 24 hour files

Files are opened at midnight and at incremental durations after midnight

8 Hour files : at midnight, 8am and 4pm

4 Hour files: at midnight, 4am, 8am, noon, 4pm and 8pm

Examples:

04052500.h04 May 25 2004 from 12:00am to 4:00am

04021908.h08 February 02 004 from 8:00am to 4:00pm

c.Auto Purge

Select to automatically purge data files, if desired

If selected, enter the number of days before data is to be purged

- Between 2 and 200

Historical Assign looks like this :

Going to Group and Add displays the configurator:

d.Collection Groups

Node

Name of SCADA Node (Defaults to local node)

All tags in this group are from this node

Rate

Collection period for the tags identified in this group

Phase

Time offset to automatically distribute the data collection load

User can modify this value

Qualifier

Name of a digital tag that defines when collect is on for a group

Collection occurs when digital tag is in a 1 state

Use of this field is optional

Tagname

Enter the Tag:Field name of the database value to be collected

Only floating point values (F_*) can be collected

Limit

Modifiable dead band limit

Used to establish the minimum change from the previously recorded value (in EGUs) that will write a new value into the trend data files

Provide savings in disk space and improve access times.

10.2Starting and Configuring Historical Assignment

The first step in defining the Historical package is to start the Historical Assign program and modify the configuration settings using the following steps:

1. From Draw select Historical Assign from the Apps menu.

The Historical Assign spreadsheet appears.

2. Select 4 Hour data files

3. Click the box to automatically purge old data.

If you do not request to purge old files, you will have to manually delete old files that you no longer need.

4.Define the number of days you would like to keep on disk by entering a number in the Days box.

Valid entries are 2 to 200 days.

Define a group of tags to be collected by Historical Collection using the following steps:

1.Move the cursor to the first groups row and double click the mouse.

The group 1 configuration window appears.

2. Change the Node to SPRAYS and the Rate to 2s

3.Enter the following tags and filed names: Note these are the Tags you entered during the dB chapter, on Page 31.

TAG

FIELD

HTANKTEMP

F_CV

COILER_TEMP

F_CV

F7_TEMP

F_CV

MD_WATER_TEMP

F_CV

Note: You may enter this information using the ? or type it into the Tagname Field in the following format:

TAG.FIELD

5.After each Tag.Field combination, click the Add button to add the combination to the Tagname listing.

6.When you have completed entering the Tag and Filed combinations to be collected, click on the Save Changes button.

At this point you will be warned:

Ignore this for the purpose of the exercise.

7.Select File from the menu and Exit.

10.3Historical Collect

a.Notes

Used to collect the data defined in historical assignment

Must be running to collect data

b.Starting Collection

Historic collect found in Mission control

Can be added to the task configuration in SCU

- use HTC.EXE in the task list

Historical collect status window displays the following:

- current node time (HH:MM:SS)

- number of collection overruns since collection was started

c.Stopping collection

Use the Stop button in Mission Control (

- this stops collection of all groups

When Fix is stopped, Historical collection is automatically shut down

10.4Start Historical Collection

Start the collection procedure by selecting the Historical Collection program using the following steps:

1.From the FIX Group, start Mission Control.

This dialog box shows you the number of collection overruns that have incurred. If overruns have occurred, check your collection rate and phasing to see if there are changes that can be made to avoid this situation.

2.From the HTC section of Mission Control, click Start to start the HTC task.

3.Close mission Control.

HTC is now running in the background.

Note: If any changes are made to a collection group in the Historic Assign program, you must Stop and re-start the HTC task for the changes to occur, the reson for this is that HTC only reads the configuration file on program start.

10.5Historic Display

Historic Display is a program that allows you to display the results of the stored for the duration of the period you have defined.

Start the Historic Display program from the FIX Group or from Draw and Apps.

You should see the following:

10.6Defining Pen Groups
