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 part 27.
Fig 1 FISCO fieldbus system

4.2 Non-FISCO SystemsFor non-FISCO applications the
BA444DF-Ffieldbus indicator has a higher voltage entityintrinsic
safety input parameter allowing connectionto a wide range of
fieldbus segments.
The BA444DF-F fieldbus indicator may beconnected to any
intrinsically safe segmentproviding:
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 fieldbus
listener.
The equivalent internal capacitance Ci of theBA444DF-F fieldbus
listener is zero and theequivalent internal inductance is
insignificant.Therefore these BA444DF-F parameters do notneed to be
considered.

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,
operatingthe P button will preview the value of the data ateach
selected 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.

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:
