4. SYSTEM DESIGN FOR HAZARDOUS AREAS

4.1 FISCO SystemsThe BA444DF-P PROFIBUS PA indicator may beconnected to any ATEX certified FISCO compliantfieldbus segment, providing the segment cansupply the additional 13mA required to operate theinstrument.

Fig 1 shows a typical fieldbus segment. To complywith FISCO requirements, the power supply,terminators, field devices and the interconnectingcables must conform with IEC60079 part 27.

Fig 1 FISCO fieldbus system

5

4.2 Non-FISCO SystemsFor non-FISCO applications the BA444DF-PPROFIBUS PA indicator has a higher voltageentity intrinsic safety input parameter allowingconnection to a wide range of fieldbus segments.

The BA444DF-P may be connected to anyintrinsically safe segment providing:

The device powering the fieldbus segment isATEX certified and has output parametersequal to or less than:

Uo = 22V dcIo = 250mA dcPo = 1.2W

The segment can provide an additional 13mAto power the BA444DF-P PROFIBUS PAindicator.

The equivalent internal capacitance Ci of theBA444DF-P PROFIBUS PA indicator is zero andthe equivalent internal inductance is insignificant.Therefore these BA444DF-P parameters do notneed to be considered.

5. INSTALLATION

6. CONFIGURATIONThe BA444DF-P 8 variable PROFIBUS PA PAindicator may be configured as a fieldbus node oras a fieldbus listener. When used as a fieldbusnode the indicator is configured via the fieldbushost although the instrument address may beentered via the front panel push buttons using themenu shown in Fig 4. For detailed nodeconditioning information please refer to the BEKAPROFIBUS PA Display – Fieldbus Interface Guidewhich may be downloaded from the BEKA websitewww.beka.co.uk

As a fieldbus listener, the BA444DF-P is not visibleto the fieldbus host and can only be configured viathe front panel push buttons using the menushown in Fig 6.

Throughout this manual the four BA444DF-P pushbuttons are identified P E ▼ ▲ and legendsdisplayed by the instrument are shown withininverted commas e.g. ‘CodE’ and ‘Enb’.

6.1 Configuration menusThe configuration menus are separated into twosections, fieldbus node and fieldbus listener. Bothcontain the ‘tYPE’ function that enables transferbetween the two. Unless otherwise requestedwhen ordered, all PROFIBUS PA BA444DF-Pinstruments are supplied as a fieldbus node withdefault configuration but can easily be reconfiguredon-site.

6.2 Node configuration menuThe node configuration menu is shown in Fig 4.Access to the menu is obtained by operating the Pand E buttons simultaneously. If the BA444DF-Pis not protected by an access code the firstparameter 'Addr’ will be displayed. If theinstrument is protected by an access code, ‘CodE’will be displayed first. Pressing P will allow thefour digit security code to be entered digit by digitusing the ▼ or ▲ button to adjust the flashing digitand P to move control to the next digit. When thecorrect code has been entered, pressing E willcause the first parameter ‘Addr’ to be displayed.If an incorrect code is entered, or no button ispressed for ten seconds, the BA444DF-P willautomatically return to the display mode.

6.2.1 Enter fieldbus address ‘Addr’This function enables the fieldbus address of theBA444DF-P to be entered via the push buttons.Select ‘Addr’ in the node menu using the ▼ or ▲button and press P to enter the function. This willreveal the existing three digit decimal address withthe left hand digit flashing which may be changedby operating the ▼ or ▲ button. When set asrequired operating the P button will transfer controlto the next digit that may be adjusted in the sameway. When all digits are set as required operatingthe E button will enter the new address and theindicator will restart in the display mode aftercompleting the initialisation sequence. If theaddress is not changed, operating the E button willreturn the display to the ‘Addr’ prompt in the nodeconfiguration menu.

6.2.2 Access code for configuration menu ‘CodE’Access to the node configuration menu may beprotected by a four digit security code which mustbe entered to gain access. New instruments aresupplied configured with the default code 0000which disables this protection and allowsunrestricted access to the configuration menu.

To enter a new access code select ‘CodE’ in thenode configuration menu by operating the ▼ or ▲button. To enter the function press P which willreveal the current access code with one digitflashing. The code may be changed using the ▼ or▲ button to adjust the flashing digit and the Pbutton to move control to the next digit. When therequired code has been selected, press E to enterthe selection and return to the ‘CodE’ prompt in theconfiguration menu. The revised access code willbe activated when the transmitter is returned to thedisplay mode.

If the access code is lost please contact BEKAassociates.

6.2.3 Change from node to listener ‘tYPE’This function enables the instrument to bechanged from a fieldbus node to a fieldbus listener.Select ‘tYPE’ in the node configuration menu usingthe ▼ or ▲ button. To enter the function press Pwhich will show that the instrument is configuredas a fieldbus node, to change to a fieldbus listenerpress the ▼ or ▲ button which will toggle thedisplay to ‘LStnr’ To prevent accidental changesthis request must be confirmed by operating the Pbutton and entering ‘5urE’. The instrument willdisplay ‘0000’ with the first digit flashing, using the▼ or ▲ button set the flashing digit to ‘5’ and pressthe P button to move control to the next digit whichshould be set to ‘u’. When the four letters of ‘5urE’have been entered, operating the E button willcause the instrument to restart as a fieldbuslistener in the display mode.

CAUTIONAll the instrument’s node configurationinformation will be lost when it ischanged from a fieldbus node to afieldbus listener.

Please refer to the quick set-up procedure in theBEKA PROFIBUS PA Display – Fieldbus InterfaceGuide.

6.2.4 Reset the instrument to node factory defaults ‘rESEt’The BA444DF-P may be reset to the factorydefaults that are shown below:

Security Code 0000 (disabled)Device address 126

For each of the eight inputs:Decimal point XXX.XXBar Type LeftBar lower limit 0.0Bar Upper limit 100.0Gain 1.0Offset 0.0

To reset the BA444DF-P select ‘rESEt’ in theconfiguration menu by operating the ▼ or ▲button. To enter the function press P which willreveal ‘0000’ with the left hand digit flashing. Toprevent accidental use of this function, ‘5urE’ mustbe entered to confirm that the instrument is to bereset.

Using the ▼ or ▲ button set the flashing digit to ‘5’and press the P button to move control to the nextdigit which should be set to ‘u’. When the fourletters of ‘5urE’ have been entered operating the Ebutton will reset the BA444DF-P to the factorydefaults. Any existing configuration andaddresses will be lost when the instrument is reset.

6.3 Listener configuration menuWhen used as a fieldbus listener the BA444DF-Pis not visible to the fieldbus host and can only beconfigured using the front panel push buttonsshown in Fig 3.

The listener configuration menu is separated intothree sections, ‘SCAn’, ‘LISt’ and ‘Edit’, plus threehousekeeping functions ‘CodE’, ‘tYPE’ and ‘rESEt’as shown in Fig 6.

‘SCAn’ is the simplest method of configuration ifthe addresses of the data sources to be displayedby the BA444DF-P listener are not known.

In the ‘SCAn’ function pressing the P buttoncauses the BA444DF-P listener to search thefieldbus segment to which it is connected for alldata sources. The hexadecimal deviceaddresses for each data source are displayed asshown in Fig 5.

The ▼ and ▲ push buttons scroll the displaythrough all the data sources on the segmentshowing the source and destination address foreach one. To aid identification, operating the Pbutton will preview the value of the data at theselected addresses with a zero index i.e. the firstfive bytes in the data string. If the format of thedata is not DS-33 (status + float) ‘no dAt’ will bedisplayed. The selected source and destinationaddresses may be allocated to one of the eightBA444DF-P listener inputs in-1, to in-8. Operatingthe P button will reveal the current listener inputwhich may be changed using the ▼ or ▲ pushbutton, when set as required, operating the E pushbutton will enter the allocation. If the processvariable to be displayed is located further along thedata stream i.e. has an index greater than 5, therequired index must be entered via the index ‘ind’function in the edit sub-menu.

A worked configuration example illustrating thisprocedure is contained in the Quick Set-up sectionof the PROFIBUS PA Interface Guide.

Fig 5 Device Addresses

If the source and destination addresses and indexof the process variable to be displayed by theBA444DF-P listener are known, they may bedirectly entered via the edit sub-menu. This sub-menu also provides full control of both the numericand bargraph display parameters.

6.4 Description of listener menu functionsThis section contains a detailed description of eachfunction in the listener configuration menu. Itshould be read in conjunction with Fig 6.

6.4.1 Scan fieldbus segment ‘SCAn’If the Device Addresses of a data source are notknown, the ‘SCAn’ function provides a simple wayto identify them. This function scans the fieldbussegment to which the BA444DF-P listener isconnected and identifies all the data sources. Toaid identification the value of the process variablewith a zero index i.e. the first five bytes in the datastring at the address may be pre-viewed.

The BA444DF-P listener only supports DS-33formatted data (status+float) which is the usualformat for analogue process variables. The‘SCAn’ function will identify, irrespective of format,all data sources on the segment whose destinationaddress is five bytes long. When pre-viewed, nonDS-33 formatted data will produce a ‘no dAt’ errormessage.

‘SCAn’ is the first function displayed when enteringthe configuration menu, or it may be selected fromwithin the menu by operating the ▼ or ▲ button.To scan the fieldbus segment to which the listeneris connected for all data sources press P which willreveal the hexadecimal source address anddestination address of the first data source foundas shown in Fig 5. If there is more than one datasource, operating the ▼ or ▲ button will scrollthough all of them.

If there are no data sources on the fieldbussegment the BA444DF-P listener will display‘noSrC’.

When the source and destination addresses of adata source are displayed, to aid identification thevalue of the process variable with a zero index i.e.the first five bytes in the data string may be pre-viewed by operating the P button. If this confirmsthat it is the required address, it may be allocatedto one of the eight BA444DF-P listener inputs in-1to in-8. To select the required listener input, pressP which will display the first input in-1. Operatingthe ▼ or ▲ button will scroll the display throughthe other inputs. When the required input isdisplayed pressing E will allocate the selected datasource address to the selected input and return thedisplay to the source and destination addressesfrom which another data source address may beselected. When a data source address is allocatedto a listener input any previous allocation will beoverwritten.

If the required process variable has an indexabove 5 i.e. it is not the first five bytes in the datastring, the required index should be entered via the‘ind’ function in the Edit sub-menu which isdescribed in section 6.4.7

6.4.2 List configured input parameters ‘LiSt’The ‘LiSt’ function enables the Source Address,Destination Address and Index allocated to eachlistener input to be viewed without danger of itbeing accidentally changed.

The ‘LiSt’ function may be selected from within themenu by operating ▼ or ▲ button. To enter thefunction press P which will display the listenerinput currently selected in the display mode, otherinputs may be selected using the ▼ or ▲ button.Operating the P button will cause the followingparameters for the selected input to be displayedsequentially:

Display Explanation‘Enb :Y or N’ Input Enabled yes or no‘SrC :00’ Source Address‘dSt :00’ Destination Address‘ind :00’ Index

The display then automatically returns to theselected BA444DF-P listener input from whereanother input may be selected.

If one of the eight BA444DF-P Listener’s inputs in-1 to in-8 has not had a Source Address,Destination Address and Index allocated to it, ‘LiSt’will show both addresses as ‘FF’ and the index‘ind’ as ‘00’.

6.4.3 Enter address & display parameters ‘Edit’The ‘Edit’ sub-menu may be selected from withinthe menu by operating ▼ or ▲ button. To enter thefunction press P which will display the listenerinput currently selected in the display mode, otherlistener inputs may be selected using the ▼ or ▲button. When the required input has beenselected operating the P button will enter the editsub-menu at ‘Enb’ for the selected input.

6.4.4 Enable selected input ‘Enb’‘Enb’ turns the listener input selected in the Editfunction on or off without affecting the conditioning.To enter the function press P which will revealwhether the selected input is ‘on’ or ‘oFF’.Operating the ▼ or ▲ buttons will toggle betweenthe two conditions. When set as requiredoperating the E button will enter the selection andreturn to the ‘Enb’ prompt in the edit sub-menu.

12

6.4.5 Enter source address ‘SrC’This function allows a known fieldbus devicesource address to be entered and allocated to thelistener input selected in the edit function. To enterthe function press P which will reveal the existingtwo digit hexadecimal address with one digitflashing which may be changed by operating the ▼or ▲ button. When set as required operating theP button will transfer control to the second digitthat may be adjusted in the same way. When bothdigits are set as required operating the E buttonwill enter the selection and return to the ‘SrC’prompt in the edit sub-menu.

6.4.6 Enter destination address ‘dSt’This function allows a known fieldbus devicedestination address to be entered and allocated tothe listener input selected in the Edit function. Toenter the function press P which will reveal theexisting two digit hexadecimal address with onedigit flashing which may be changed by operatingthe ▼ or ▲ button. When set as required operatingthe P button will transfer control to the second digitthat may be adjusted in the same way. When bothdigits are set as required operating the E buttonwill enter the selection and return to the ‘dSt’prompt in the edit sub-menu.

6.4.7 Enter Index ‘ind’Index defines the location of the required processvariable in the data string. The ‘ind’ function allowsa known Index for the selected fieldbus SourceAddress to be entered and allocated to theBA444DF-P listener input selected in the Editfunction. The data location is manufacturer specificand can not be automatically determined; thedevice documentation should therefore beconsulted. To enter the function press P which willreveal the existing two digit hexadecimal addresswith one digit flashing which may be changed byoperating the ▼ or ▲ button. When set as requiredoperating the P button will transfer control to thesecond digit that may be adjusted in the sameway. When both digits are set as requiredoperating the E button will enter the selection andreturn to the ‘ind’ prompt in the edit sub-menu.

6.4.8 Decimal point position ‘dP’This defines the position the decimal point in thenumeric display. To enter the function press Pwhich will reveal the existing decimal pointposition. Operating the ▼ or ▲ button will movethe decimal point to the required position, omit it,or activate all the decimal points whichautomatically provides maximum resolution in thedisplay mode irrespective of the numeric value.When positioned as required, operating the Ebutton will enter the selection and return to the ‘dP’prompt in the edit sub-menu.

6.4.9 Configuration of bargraph display ‘bAr’This function contains three sub-functions thatenable the bargraph, justify its position and definethe relationship between the bargraph and theinstrument’s numeric display.

Sub-function ‘b.tYPE’ enables the bargraph to beleft, centre or right justified, or to be turned off.Sub-functions ‘bArLo’ and ‘bArhi’ define thelistener’s numeric display at which the bargraphstarts and is at full scale.The ‘bAr’ function may be selected from within theedit sub-menu by operating the ▼ or ▲ button.To enter the function press P which will display the‘b.tYPE’ sub-function, pressing P again will revealthe existing bargraph justification. The ▼ or ▲button will scroll through the four options, when therequired justification is displayed, pressing E willenter the selection and return the display to the‘b.tYPE’ prompt in the edit sub-menu from which‘bArLo’ may be selected using the ▼ or ▲ button.

‘bArLo’ defines the listener’s numeric display atwhich the bargraph starts, to enter the functionpress P which will reveal the existing setting. Thedisplay may be changed using the ▼ or ▲ buttonto adjust the flashing digit and the P button tomove control to the next digit. When the requiredstarting display has been selected, press E toreturn to the ‘bArLo’ prompt in the edit sub-menufrom which the ‘bArHi’ function may be selected.

‘bArHi’ defines the listener’s numeric display atwhich the bargraph is full scale, to enter thefunction press P which will reveal the existingsetting. The display may be changed using the ▼or ▲ button to adjust the flashing digit and the Pbutton to move control to the next digit. When therequired display has been selected, press E twiceto enter the new values and return to the ‘bAr’prompt in the edit sub-menu.

Note: If the ‘dP’ function has been set to provideautomatic maximum resolution irrespective of thedisplayed value, it may be necessary to manuallyposition the decimal point before adjusting ‘bArLo’or ‘bArHi’. This can be achieved by repeatedlyoperating the P button until the activated decimalpoint flashes, the decimal point can then bepositioned using either the ▼ or ▲ button.Pressing the P button again will return control toone of the digits.

6.4.10 Scale numeric display ‘SCALE’A scaling factor ‘Gain’ and an offset ‘oFFSt’ maybe applied to the fieldbus process variable usingthis function, thus allowing the listener to displaythe fieldbus process variable in alternative units.

13

The ‘SCALE’ function may be selected from withinthe edit sub-menu by operating the ▼ or ▲ button.To enter the function press P which will display the‘GAin’ sub-function, pressing P again will revealthe existing gain with one digit flashing. Thisflashing digit may be changed by operating the ▼or ▲ button; when adjusted the P button will movecontrol to the next digit or to the decimal pointwhich can be positioned using the ▼ or ▲ button.When ‘GAin’ has been set to the required valueoperating the E button will enter the selection andreturn to the ‘GAin’ prompt in the sub-menu fromwhere the ‘oFFSt’ function can be selected usingthe ▼ or ▲ button.

To enter the ‘oFFSt’ function press P which willreveal the existing offset with one digit flashing.Again the flashing digit may be changed byoperating the ▼ or ▲ button and the P button willmove control to the next digit or to the decimalpoint.
