1. DESCRIPTION
The BA644DF-P fieldbus indicator is a 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 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
BA644DF-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 IP66 glass reinforced polyester
(GRP) enclosure with a toughened glass window,
the BA644DF-P is surface mounting, or may be
pipe mounted using one of the accessory kits.
The instrument’s communication protocol is shown
on a label inside the terminal cover. The ‘-P’ order
code suffix also indicates the protocol but is not
shown on the instrument identification label.
There is an alternative version of the fieldbus
display, order code BA644DF-F for use on
FOUNDATION™ fieldbus networks.
1.1 Documentation
This instruction manual describes installation,
configuration and use of the BA644DF-P as a

5. CONFIGURATION
The BA644DF-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 BA644DF-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 four BA644DF-P push
buttons are identified P E ▼▲and legends
displayed by the instrument are shown within
inverted commas e.g. ‘CodE’ and ‘Enb’.
5.1 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 BA644DF-P
instruments are supplied as a fieldbus node with
default configuration but can easily be reconfigured
on-site.
5.2 Node configuration menu
The node configuration menu is shown in Fig 4.
Access to the menu is obtained by operating the P

FIG 4 Node configuration menu
5.3 Listener configuration menu
When used as a fieldbus listener the BA644DF-P
is not visible to the fieldbus host and can only be
configured using the front panel push buttons
shown in Fig 3.
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 BA644DF-P listener are not known.
In the ‘SCAn’ function pressing the Pbutton
causes the BA644DF-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
BA644DF-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
BA644DF-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.

5.3.1 Access
Access to the listener configuration menu is
obtained by operating the Pand Ebuttons
simultaneously. If the BA644DF-P listener
configuration menu is not protected by an access
code the first parameter 'SCAn’ will be displayed.
If the BA644DF-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.

5.4 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.
5.4.1 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 BA644DF-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 BA644DF-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 BA644DF-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 BA644DF-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 section5.4.7
5.4.2 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 BA644DF-P listener input from where
another input may be selected.
If one of the eight BA644DF-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’.
5.4.3 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.
5.4.4 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
5.4.5 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.
5.4.6 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.
5.4.7 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
BA644DF-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 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 ‘ind’ prompt in the edit sub-menu.
5.4.8 Decimal point position ‘dP’
This defines the position the decimal point in the
numeric display. To enter the function press P
which will reveal the existing decimal point
position. Operating the ▼or ▲button will move
the decimal point to the required position, omit it,
or activate all the decimal points which
automatically provides maximum resolution in the
display mode irrespective of the numeric value.
When positioned as required, operating the E
button will enter the selection and return to the ‘dP’
prompt in the edit sub-menu.
5.4.9 Configuration of bargraph display ‘bAr’
This function contains three sub-functions that
enable the bargraph, justify its position and define
the relationship between the bargraph and the
instrument’s numeric display.
Sub-function ‘b.tYPE’ enables the bargraph to be
left, centre or right justified, or to be turned off.
Sub-functions ‘bArLo’ and ‘bArhi’ define 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.
5.4.10 Scale numeric display ‘SCALE’
A scaling factor ‘Gain’ and an offset ‘oFFSt’ may
be applied to the fieldbus process variable using
this function, thus allowing the listener to display
the fieldbus process variable in alternative units.

ENSURE PLANT SAFETY BEFORE
STARTING MAINTENANCE
If a BA644DF-P fails after it has been functioning
correctly, the table shown in section 6.1 may help
to identify the cause of the failure.
If this procedure does not reveal the cause of the
fault, it is recommended that the instrument is
replaced.
6.3 Servicing
We recommend that faulty BA644DF-P PROFIBUS
PA Indicators are returned to BEKA associates or
to our local agent for repair.
6.4 Routine maintenance
The mechanical and electrical condition of the
instrument should be regularly checked. Initially
annual inspections are recommended, but the
inspection frequency should be adjusted to suit the
environmental conditions.

7. ACCESSORIES
7.1 Scale and tag marking
BA644DF-P PROFIBUS PA Indicators are fitted
with a blank escutcheon around the liquid crystal
display. If specified when the instrument is
ordered, this can be supplied printed with units of
measurement and tag information, plus a scale for
the horizontal bargraph. Alternatively, information
may be added on-site via an embossed strip, dry
transfer or a permanent marker.
To gain access to the display escutcheon remove
the terminal cover by unscrewing the two 'A'
screws which will reveal two concealed 'D' screws.
Unscrew all four 'D' screws and carefully lift off the
front of the instrument. The location of these
screws is shown in Fig 2.
After adding the required legends, or fitting a new
pre-printed self-adhesive escutcheon, ensure that
the gasket is correctly positioned before
reassembling the instrument enclosure.
7.2 Tag plate
The BA644DF-P can be supplied with a blank or
custom laser marked stainless steel plate secured
by two screws to the front of the instrument
enclosure. This plate can accommodate:
1 row of 9 alphanumeric characters 10mm high
or 1 row of 11 alphanumeric characters 7mm high
or 2 rows of 18 alphanumeric characters 5mm
high.
or 8 cells each containing units of measurement or
identification for one of the 8 inputs.
7.3 Pipe mounting kits
Two pipe mounting kits are available for securing
the BA644DF-P to a horizontal or vertical pipe.
