4. SYSTEM DESIGN FOR HAZARDOUS AREAS

4.1 FISCO SystemsThe BA444DF-F fieldbus 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 IEC60079-11.

Fig 1 FISCO fieldbus system

4.2 Ex ia entity systemsThe BA444DF-F Fieldbus Indicator has Ex iacertification with entity parameters for applicationsin Zone 0, 1 and 2.

The BA444DF-F Fieldbus Indicator may beconnected to any intrinsically safe segmentproviding:

The device powering the fieldbus segment isATEX Ex ia certified for Zone 0, 1 or 2applications, or Ex ib certified for applicationin Zone 1 or 2, or Ex ic certified forapplications in Zone 2. The outputparameters of the segment should be equalto or less than:

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

The segment can provide an additional 13mAto power the Fieldbus Indicator.

The equivalent capacitance Ci of theBA444DF-F Fieldbus Indicator is zero andthe equivalent inductance is insignificant.Therefore these BA444DF-F parameters donot need to be considered.

4.3 Ex ic entity systemsThe BA444DF-F Fieldbus Indicator also has Ex iccertification with entity parameters for applicationsin Zone 2. The higher Ui voltage allows theindicator to be used with segment couplerspowered by Ex e or Power-i fieldbus trunks.

When mounted in Zone 2 the BA444DF-F FieldbusIndicator may be connected to any intrinsically safesegment providing:

The device powering the fieldbus segment isATEX Ex ia, ib or ic certified and has outputparameters equal to or less than:

Uo = 32V dcIo = 125mA dcPo = 1W

6.3 Listener configuration menuThe 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 fieldbus Device Address and Variable Identityof the data to be displayed by the BA444DF-Flistener are not known.

In the ‘SCAn’ function pressing the P buttoncauses the BA444DF-F indicator to search thefieldbus segment to which it is connected for allpublishers. Fig 5 shows how the indicator displaysthe hexadecimal Device Address and VariableIdentity associated with each publisher.

A Publisher is a device that places it's outputdata onto the bus as part of a cyclical pre-determined data exchange schedule.

The Device Address is a unique address thatidentifies each fieldbus instrument connected tothe bus.

The Variable Identity is the fieldbus deviceData Link Connection End Point (DLCEP)which identifies each Function Block output(process variable) transmitted by a fieldbusdevice such as flow and temperaturetransmitted by a fieldbus flowmeter.

The ▼ and ▲ push buttons scroll the displaythrough all the publishers on the segment showingthe Device Address and Variable Identity for eachone - see Fig 5. To aid identification, operating theP button will preview the value of the data at eachselected address, if required it may then beallocated to one of the eight BA444DF-F listenerinputs in-1, to in-8 by operating the P button again.If the format of the data at the selected DeviceAddress and Variable Identity is not DS-65 (float +status) ‘no dAt’ will be displayed.

Fig 5 Device Address and Variable Identity

If the Device Address and Variable Identity of theprocess variable to be displayed by the BA444DF-F indicator are known, they may be directly enteredvia the edit sub-menu. This sub-menu alsoprovides full control of both the numeric andbargraph display parameters.

6.3.3 Scan fieldbus segment ‘SCAn’If the Device Address and Variable Identity of aprocess variable are not known, the ‘SCAn’function provides a simple way to identify them.This function scans the fieldbus segment to whichthe BA444DF-F indicator is connected andidentifies all the publishers. To aid identification itenables the value of each process variable to bepre-viewed and, if required, allocated to one of theeight BA444DF-F Fieldbus indicator inputs.

The BA444DF-F indicator only supports DS-65formatted data (float + status) which is the usualformat for analogue process variables. The‘SCAn’ function will identify all publishers on thesegment irrespective of format, but when pre-viewed, non DS-65 formatted data will produce a‘no dAt’ error message.

‘SCAn’ is the first function displayed when enteringthe listener configuration menu, or it may beselected from within the menu by operating the ▼or ▲ button. To scan the fieldbus segment towhich the indicator is connected for all publisheddata press P which will reveal the hexadecimalDevice Address and Variable Identity of the firstpublisher found as shown in Fig 5. If there ismore than one publisher operating the ▼ or ▲button will scroll though all of them.

If no cyclic data is being published on the fieldbussegment the BA444DF-F indicator will display‘noPub’. When the Device Address and Variable Identity ofa process variable is being displayed, pressing Pwill preview the value of the process variabledisplayed with maximum resolution on the five digitdisplay. If this confirms that it is one of theprocess variables to be displayed, it may beallocated to one of the eight BA444DF-F listenerinputs in-1 to in-8.

To select the required indicator input press P todisplay the first input in-1, operating the ▼ or ▲button will scroll the display through the otherinputs. When the required input is displayedpressing E will allocate the selected processvariable to the selected input and return the displayto the Device Address and Variable Identity fromwhich another process variable may be selected.

When a process variable is allocated to a indicatorinput any previous allocation will be overwritten.

6.3.4 List configured input parameters ‘LiSt’The ‘LiSt’ function enables the Device Address andVariable Identity allocated to each lindicator inputto be viewed without danger of it being accidentallychanged.

The ‘LiSt’ function may be selected from within themenu by operating ▼ or ▲ button. To enter thefunction press P which will display the indicatorinput 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‘Adr: 00’ Device Address ‘id: 00’ Variable Identity

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

If one of the eight BA444DF-F indicator’s inputs in-1 to in-8 has not had a Device Address andVariable Identity allocated to it, ‘LiSt’ will show bothas invalid address FF.

6.3.5 Enter address & display parameters ‘Edit’The ‘Edit’ function may be selected from within themenu by operating ▼ or ▲ button. To enter thefunction press P which will display the indicatorinput currently selected in the display mode, otherlistener inputs may be selected using the ▼ or ▲button. When the required input has been selectedoperating the P button will enter the edit sub-menuat ‘Enb’ for the selected input.

6.3.6 Enable selected input ‘Enb’‘Enb’ turns the indicator 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 edit sub-menu.

6.3.7 Enter Device Address ‘Adr’This function allows a known fieldbus DeviceAddress to be entered and allocated to theindicator 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 requiredoperating the P button will transfer control to thesecond digit that may be adjusted in the same way.When both digits are set as required operating theE button will enter the selection and return to the‘Adr’ prompt in the edit sub-menu. 6.3.8 Enter Variable Identity ‘id’Enables a known Variable Identity to be enteredand allocated to the indicator input selected in theEdit function. To enter the function press P whichwill reveal the existing two digit hexadecimaladdress with one digit flashing which may bechanged by operating the ▼ or ▲ button. Whenset as required operating the P button will transfercontrol to the second digit that may be adjusted inthe same way. When both digits are set asrequired operating the E button will enter theselection and return to the ‘id’ prompt in the editsub-menu.

6.3.9 Decimal point position ‘dP’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, oractivate all the decimal points which automaticallyprovides maximum resolution in the display modeirrespective 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.

6.3.10 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’ allows 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 fouroptions, when the required justification isdisplayed, pressing E will enter the selection andreturn the display to the ‘b.tYPE’ prompt in the editsub-menu from which ‘bArLo’ may be selectedusing the ▼ or ▲ button.

‘bArLo’ defines the indicator’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 indicator’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.

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

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 reveal theexisting gain with one digit flashing. This flashingdigit 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.
