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.

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
5.1 LocationThe BA444DF-P PROFIBUS PA indicator ishoused in a
robust IP66 glass reinforced polyester(GRP) enclosure incorporating
an armoured glasswindow and stainless steel fittings. It is
suitable forexterior mounting in most industrial
environments,including offshore and wastewater
treatmentinstallations. Please consult BEKA associates ifhigh
vibration is anticipated.
The BA444DF-P enclosure is surface mounting.Accessory kits
described in sections 8.3 of thismanual enable the instrument to be
mounted ontoa vertical or horizontal pipe.
The field terminals and the two mounting holes arelocated in a
separate compartment with a sealedcover allowing the instrument to
be installedwithout exposing the display assembly.
The BA444DF-P earth terminal is connected to thecarbon loaded
GRP enclosure. If this enclosure isnot bolted to a post or
structure connected to theplant potential equalising network, the
instrument’searth terminal should be connected to thepotential
equalising network as recommenced inEN 60079-14.
The BA444DF-P enclosure is supplied with abonding plate to
ensure electrical continuitybetween the three conduit / cable

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.

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.
