1. DESCRIPTION
The BA448CF-P fieldbus indicator is an intrinsically
safe, PROFIBUS PA instrument that may be
configured as a fieldbus node or as a fieldbus
listener. It can display up to eight fieldbus process
variables on a five digit LCD and a 31 segment
analogue bargraph. The instrument is bus
powered so no additional power supply is required
and it has PROFIBUS PA User Organisation
approval, certificate Z01505.
Fieldbus node configuration may be performed by
either a User PRM data download or by a DPV1
configurator, and if required, the instrument
address may be entered via the front panel push
buttons.
When configured as a fieldbus listener, the
BA448CF-P is not visible to the fieldbus host and
can only be configured using the push buttons on
the front of the instrument.
Housed in a robust 72 x 144 panel mounting DIN
enclosure, the BA448CF-P fieldbus indicator has
an IP66 front panel and is supplied with a gasket to
seal the joint between the instrument & the panel.
The instrument is intrinsically safe and has been
certified by European Notified Body Intertek
Testing and Certification Ltd (ITS) to the ATEX
Directive 94/9/EC for use in explosive gas
atmospheres.
The BA448CF-P also has intrinsic safety and
nonincendive FM and cFM Approval allowing
installation in the USA and Canada – see
Appendix 1.
For international applications the BA448CF-P
fieldbus indicator has IECEx intrinsic safety
approval – see Appendix 2.
The instrument’s communication protocol is shown
on the rear of the instrument. The ‘-P’ order code
suffix also indicates the protocol but is not shown
on the instrument certification label. There is an
alternative version of the fieldbus display, order
code BA448CF-F for use on FOUNDATION™
fieldbus networks.

4. SYSTEM DESIGN FOR HAZARDOUS
AREAS
4.1 FISCO Systems
The BA448CF-P may be connected to any ATEX
certified FISCO compliant fieldbus segment,
providing the segment can supply the additional
13mA required to power the instrument.
Fig 1 shows a typical fieldbus segment. To comply
with FISCO requirements, the power supply,
terminators, field devices and the interconnecting
cables must conform to EN 60079 part 27.
Fig 1 FISCO fieldbus system
4.2 Non-FISCO Systems
For non-FISCO applications the BA448CF-P
Fieldbus Indicator has a higher voltage entity
intrinsic safety input parameter allowing connection
to a wide range of fieldbus segments.
The BA448CF-P Fieldbus Indicator may be
connected to any intrinsically safe segment
providing:
The device powering the fieldbus segment is
ATEX certified and has output parameters
equal to or less than:
Uo = 22V dc
Io = 250mA dc
Po = 1.2W
The segment can provide an additional
13mA to power the Fieldbus Indicator.
Note: The equivalent capacitance Ci of the
BA448CF-P Fieldbus Indicator is zero and
the equivalent inductance is insignificant.
Therefore these BA448CF-P safety
parameters do not need to be considered.

5. INSTALLATION
5.1 Location
The BA448CF-P is housed in a robust aluminium
enclosure with a toughened glass window mounted
in a Noryl bezel. The front of the instrument
provides IP66 protection and a gasket seals the
joint between the instrument enclosure and the
panel. The instrument may be installed in any
panel providing the environmental limits shown in
the specification are not exceeded.
Fig 2 shows the overall dimensions of the
BA448CF-P and the panel cut-out. To achieve an
IP66 seal between the instrument enclosure and
the panel, the smaller cut-out must be used and
the instrument secured with four panel mounting
clips.
CAUTION
Installation in Zone 0
When installed in a Zone 0 potentially
explosive atmosphere requiring apparatus
of Category 1G, the indicator shall be
installed such that even in the event of rare
incidents, an ignition source due to impact
or friction between the aluminium enclosure
at the rear of the instrument mounting panel
and iron/steel is excluded.

6. CONFIGURATION
The BA448CF-P 8 variable PROFIBUS PA
indicator may be configured as a fieldbus node or
as a fieldbus listener. When used as a fieldbus
node the indicator is configured via the fieldbus
host although the instrument address may be
entered via the front panel push buttons using the
menu shown in Fig 4. For detailed node
conditioning information please refer to the BEKA
PROFIBUS PA Display – Fieldbus Interface Guide
which may be downloaded from the BEKA website
www.beka.co.uk
As a fieldbus listener, the BA448CF-P is not visible
to the fieldbus host and can only be configured via
the front panel push buttons using the menu
shown in Fig 6.
Throughout this manual the BA448CF-P push
buttons are identified P E ▼▲and legends
displayed by the instrument are shown within
inverted commas e.g. ‘CodE’ and ‘Enb’.
6.1 Configuration menus
The configuration menus are separated into two
sections, fieldbus node and fieldbus listener. Both
contain the ‘tYPE’ function that enables transfer
between the two. Unless otherwise requested
when ordered, all PROFIBUS PA BA448CF-P
instruments are supplied as a fieldbus node with
default configuration but can easily be reconfigured
on-site.
6.2 Node configuration menu
The node configuration menu is shown in Fig 4.
Access to the menu is obtained by operating the P
and Ebuttons simultaneously. If the BA448CF-P
is not protected by an access code the first
parameter 'Addr’ will be displayed. If the
instrument is protected by an access code, ‘CodE’
will be displayed first. Pressing Pwill allow the
four digit security code to be entered digit by digit
using the ▼or ▲button to adjust the flashing digit
and Pto move control to the next digit. When the
correct code has been entered, pressing Ewill
cause the first parameter ‘Addr’ to be displayed.
If an incorrect code is entered, or no button is
pressed for ten seconds, the BA448CF-P will
automatically return to the display mode.

to the next digit that may be adjusted in the same
way.
When all digits are set as required operating the E
button will enter the new address and the indicator
will restart in the display mode after completing the
initialisation sequence. If the address is not
changed, operating the Ebutton will return the
display to the ‘Addr’ prompt in the node
configuration menu.
6.2.2 Access code for configuration menu
‘CodE’
Access to the node configuration menu may be
protected by a four digit security code which must
be entered to gain access. New instruments are
supplied configured with the default code 0000
which disables this protection and allows
unrestricted access to the configuration menu.
To enter a new access code select ‘CodE’ in the
node configuration menu by operating the ▼or ▲
button. To enter the function press Pwhich will
reveal the current access code with one digit
flashing. The code may be changed using the ▼or

FIG 4 Node configuration menu
6.3 Listener configuration menu
When used as a fieldbus listener the BA448CF-P
is not visible to the fieldbus host and can only be
configured using the front panel push buttons
shown in Fig 2.
The listener configuration menu is separated into
three sections, ‘SCAn’, ‘LISt’ and ‘Edit’, plus three
housekeeping functions ‘CodE’, ‘tYPE’ and ‘rESEt’
as shown in Fig 6.
‘SCAn’ is the simplest method of configuration if
the addresses of the data sources to be displayed
by the BA448CF-P listener are not known.
In the ‘SCAn’ function pressing the Pbutton
causes the BA448CF-P listener to search the
fieldbus segment to which it is connected for all
data sources. The hexadecimal device
addresses for each data source are displayed as
shown in Fig 5.
The ▼and ▲push buttons scroll the display
through all the data sources on the segment
showing the source and destination address for
each one. To aid identification, operating the P
button will preview the value of the data at the
selected addresses with a zero index i.e. the first
five bytes in the data string. If the format of the
data is not DS-33 (status + float) ‘no dAt’ will be
displayed. The selected source and destination
addresses may be allocated to one of the eight
BA448CF-P listener inputs in-1, to in-8. Operating
the Pbutton will reveal the current listener input
which may be changed using the ▼or ▲push
button, when set as required, operating the Epush
button will enter the allocation. If the process
variable to be displayed is located further along the
data stream i.e. has an index greater than 5, the
required index must be entered via the index ‘ind’
function in the edit sub-menu.
A worked configuration example illustrating this
procedure is contained in the Quick Set-up section
of the BEKA PROFIBUS PA Display – Fieldbus
Interface Guide.
Fig 5 Device Addresses
If the source and destination addresses and index
of the process variable to be displayed by the
BA448CF-P listener are known, they may be
directly entered via the edit sub-menu. This sub-
menu also provides full control of both the numeric
and bargraph display parameters.

6.3.1 Access
Access to the listener configuration menu is
obtained by operating the Pand Ebuttons
simultaneously. If the BA448CF-P listener
configuration menu is not protected by an access
code the first parameter 'SCAn’ will be displayed.
If the BA448CF-P is protected by an access code,
‘CodE’ will be displayed first. Pressing Pwill allow
the four digit security code to be entered digit by
digit using the ▼or ▲button to adjust the flashing
digit and Pto move control to the next digit. When
the correct code has been entered, pressing Ewill
cause the first parameter ‘SCAn’ to be displayed.
If an incorrect code is entered, or no button is
pressed for ten seconds, the indicator will
automatically return to the display mode.
Section 6.3.2 contains a summary of each
configuration function including a cross reference

6.4 Description of listener menu functions
This section contains a detailed description of each
function in the listener configuration menu. It
should be read in conjunction with Fig 6.
6.4.1 Scan fieldbus segment ‘SCAn’
If the Device Addresses of a data source are not
known, the ‘SCAn’ function provides a simple way
to identify them. This function scans the fieldbus
segment to which the BA448CF-P listener is
connected and identifies all the data sources. To
aid identification the value of the process variable
with a zero index i.e. the first five bytes in the data
string at the address may be pre-viewed.
The BA448CF-P listener only supports DS-33
formatted data (status+float) which is the usual
format for analogue process variables. The ‘SCAn’
function will identify, irrespective of format, all data
sources on the segment whose destination
address is five bytes long. When pre-viewed, non
DS-33 formatted data will produce a ‘no dAt’ error
message.
‘SCAn’ is the first function displayed when entering
the configuration menu, or it may be selected from
within the menu by operating the ▼or ▲button.
To scan the fieldbus segment to which the listener
is connected for all data sources press Pwhich will
reveal the hexadecimal source address and
destination address of the first data source found
as shown in Fig 5. If there is more than one data
source, operating the ▼or ▲button will scroll
though all of them.
If there are no data sources on the fieldbus
segment the BA448CF-P listener will display
‘noSrC’.
When the source and destination addresses of a
data source are displayed, to aid identification the
value 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 Pbutton. If this confirms
that it is the required address, it may be allocated
to one of the eight BA448CF-P listener inputs in-1
to in-8. To select the required listener input, press
Pwhich will display the first input in-1. Operating
the ▼or ▲button will scroll the display through
the other inputs. When the required input is
displayed pressing Ewill allocate the selected data
source address to the selected input and return the
display to the source and destination addresses
from which another data source address may be
selected. When a data source address is allocated
to a listener input any previous allocation will be
overwritten.
If the required process variable has an index
above 5 i.e. it is not the first five bytes in the data
string, the required index should be entered via the
‘ind’ function in the Edit sub-menu which is
described 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 each
listener input to be viewed without danger of it
being accidentally changed.
The ‘LiSt’ function may be selected from within the
menu by operating ▼or ▲button. To enter the
function press Pwhich will display the listener input
currently selected in the display mode, other inputs
may be selected using the ▼or ▲button.
Operating the Pbutton will cause the following
parameters for the selected input to be displayed
sequentially:
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 the
selected BA448CF-P listener input from where
another input may be selected.
If one of the eight BA448CF-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 within
the menu by operating ▼or ▲button. To enter the
function press Pwhich will display the listener input
currently selected in the display mode, other
listener inputs may be selected using the ▼or ▲
button. When the required input has been
selected operating the Pbutton will enter the edit
sub-menu at ‘Enb’ for the selected input.
6.4.4 Enable selected input ‘Enb’
‘Enb’ turns the listener input selected in the Edit
function on or off without affecting the conditioning.
To enter the function press Pwhich will reveal
whether the selected input is ‘on’ or ‘oFF’.
Operating the ▼or ▲buttons will toggle between
the two conditions. When set as required
operating the Ebutton will enter the selection and
return to the ‘Enb’ prompt in the edit sub-menu.

11
6.4.5 Enter source address ‘SrC’
This function allows a known fieldbus device
source address to be entered and allocated to the
listener input selected in the edit function. To enter
the function press Pwhich will reveal the existing
two digit hexadecimal address with one digit
flashing which may be changed by operating the ▼
or ▲button. When set as required operating the
Pbutton will transfer control to the second digit that
may be adjusted in the same way. When both
digits are set as required operating the Ebutton
will 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 device
destination address to be entered and allocated to
the listener input selected in the Edit function. To
enter the function press Pwhich will reveal the
existing two digit hexadecimal address with one
digit flashing which may be changed by operating
the ▼or ▲button. When set as required operating
the Pbutton will transfer control to the second digit
that may be adjusted in the same way. When both
digits are set as required operating the Ebutton
will 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 process
variable in the data string. The ‘ind’ function allows
a known Index for the selected fieldbus Source
Address to be entered and allocated to the
BA448CF-P listener input selected in the Edit
function. The data location is manufacturer specific
and can not be automatically determined; the
device documentation should therefore be
consulted. To enter the function press Pwhich will
reveal the existing two digit hexadecimal Index with
one digit flashing which may be changed by
operating the ▼or ▲button. When set as required
operating the Pbutton will transfer control to the
second digit that may be adjusted in the same way.
When both digits are set as required operating the
Ebutton will enter the selection and return to the
‘ind’ prompt in the edit sub-menu.
6.4.8 Decimal point position ‘dP’
This defines the position the decimal point in the

setting. The display may be changed using the ▼
or ▲button to adjust the flashing digit and the P
button to move control to the next digit. When the
required display has been selected, press Etwice
to enter the new values and return to the ‘bAr’
prompt in the edit sub-menu.
Note: If the ‘dP’ function has been set to provide
automatic maximum resolution irrespective of the
displayed value, it may be necessary to manually
position the decimal point before adjusting ‘bArLo’
or ‘bArHi’. This can be achieved by repeatedly
operating the Pbutton until the activated decimal
point flashes, the decimal point can then be
positioned using either the ▼or ▲button.
Pressing the Pbutton again will return control to
one of the digits.
