1. DESCRIPTION
The BA648CF-F fieldbus indicator is a general
purpose FOUNDATION™ fieldbus 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 31
segment analogue bargraph. The instrument is
bus powered so no additional power supply is
required.
As a fieldbus node the indicator is configured via
the fieldbus host.
Communication Fieldbus Function
Protocol Blocks
FOUNDATION™ fieldbus Input Selector (2 x IS)
Digital input (6 x DI)
Device Description files may be downloaded from
the Fieldbus Foundation or from the BEKA
associates websites.
When configured as a fieldbus listener the
BA648CF-F 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 BA648CF-F has an IP66 front panel
and is supplied with a gasket to seal the joint
between the instrument and the panel.
The instrument’s communication protocol is shown
on the rear of the instrument. The ‘-F’ order code
suffix also indicates the protocol but is not shown
on the instrument idendification label. There is an
alternative version of the fieldbus display, order
code BA648CF-P for use on PROFIBUS PA
networks.
2. OPERATION
The BA648CF-F fieldbus indicator can display up
to eight pre-configured FOUNDATION™ fieldbus
process variables designated in-1 to in-8. The
operator can select which variable is displayed
using the ▼and ▲push buttons which scroll the
display through the eight inputs. A numeric
annunciator on the left hand side of the display
shows which of the eight inputs is currently being
displayed.
2.1 Error messages
When the BA648CF-F is configured as a listener
the following error messages may be displayed:
‘no ConF’ No inputs have been
configured or are enabled.
‘no dAtA’ No data is being received
with the current configuration.
3. SYSTEM DESIGN
The BA648CF-F FOUNDATION™ fieldbus indi-
cator is powered via the fieldbus which is
connected to non-polarised terminals 1 and 2 as
shown in Fig 1. The indicator may be connected to
any FOUNDATION™ fieldbus segment that can
supply an additional 13mA at between 9 and 32V.

4.1 Location
The BA648CF-F 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
BA648CF-F 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.
Fig 2 BA648CF-F dimensions
4.2 Installation Procedure
a. Insert the BA648CF-F into the instrument
panel cut-out from the front of the panel.
b. Fix panel mounting clips to opposite sides of
the instrument and tighten until the
instrument is secure. Four clips are required
to achieve an IP66 seal between the
instrument enclosure and the panel.
c. Connect the panel wiring to the rear terminal
block as shown in Fig 3. To simplify
installation, the terminals are removable so
that panel wiring can be completed before
the instrument is installed.

5. CONFIGURATION
The BA648CF-F 8 variable FOUNDATION™
fieldbus 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. For detailed node conditioning
information please refer to the BEKA
FOUNDATION™ fieldbus Interface Guide which
may be downloaded from www.beka.co.uk
As a fieldbus listener the BA648CF-F 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 BA648CF-F push
buttons are identified P E ▼▲and legends
displayed by the fieldbus indicator are shown
within inverted commas e.g. ‘CodE’ and ‘LiSt’.
5.1 Configuration menus
The configuration menu is 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 FOUNDATION™ fieldbus
BA648CF-F indicators are supplied as fieldbus
nodes 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

5.3 Listener configuration menu
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 fieldbus Device Address and Variable Identity
of the data to be displayed by the BA648CF-F
listener are not known.
In the ‘SCAn’ function pressing the Pbutton
causes the BA648CF-F indicator to search the
fieldbus segment to which it is connected for all
publishers. Fig 5 shows how the indicator displays
the hexadecimal Device Address and Variable
Identity associated with each publisher.
A Publisher is a device that places it's output
data onto the bus as part of a cyclical pre-
determined data exchange schedule.
The Device Address is a unique address that
identifies each fieldbus instrument connected to
the bus.
The Variable Identity is the fieldbus device
Data Link Connection End Point (DLCEP)
which identifies each Function Block output
(process variable) transmitted by a fieldbus
device such as flow and temperature
transmitted by a fieldbus flowmeter.
The ▼and ▲push buttons scroll the display
through all the publishers on the segment showing
the Device Address and Variable Identity for each
one - see Fig 5. To aid identification, operating
the Pbutton will preview the value of the data at
each selected address, if required it may then be
allocated to one of the eight BA648CF-F listener
inputs in-1, to in-8 by operating the Pbutton again.
If the format of the data at the selected Device
Address 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 the
process variable to be displayed by the BA648CF-
F indicator 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 BA648CF-F is not protected
by an access code the first parameter 'SCAn’ will
be displayed.*If the indicator 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.
* If the indicator displays ‘rESEt’ it is conditioned
as a fieldbus node, see section 5.2.2 to change it
to a fieldbus listener.

5.3.3 Scan fieldbus segment ‘SCAn’
If the Device Address and Variable Identity of a
process variable are not known, the ‘SCAn’
function provides a simple way to identify them.
This function scans the fieldbus segment to which
the BA648CF-F indicator is connected and
identifies all the publishers. To aid identification it
enables the value of each process variable to be
pre-viewed and, if required, allocated to one of the
eight BA648CF-F Fieldbus indicator inputs.
The BA648CF-F indicator only supports DS-65
formatted data (float + status) which is the usual
format for analogue process variables. The
‘SCAn’ function will identify all publishers on the
segment 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 entering
the listener configuration menu, or it may be
selected from within the menu by operating the ▼
or ▲button. To scan the fieldbus segment to
which the indicator is connected for all published
data press Pwhich will reveal the hexadecimal
Device Address and Variable Identity of the first
publisher found as shown in Fig 5. If there is
more than one publisher operating the ▼or ▲
button will scroll though all of them.
If no cyclic data is being published on the fieldbus
segment the BA648CF-F indicator will display
‘noPub’.
When the Device Address and Variable Identity of
a process variable is being displayed, pressing P
will preview the value of the process variable
displayed with maximum resolution on the five digit
display. If this confirms that it is one of the
process variables to be displayed, it may be
allocated to one of the eight BA648CF-F listener
inputs in-1 to in-8.
To select the required listener input press Pto
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 process
variable to the selected input and return the display
to the Device Address and Variable Identity from
which another process variable may be selected.
When a process variable is allocated to a indicator
input any previous allocation will be overwritten.
5.3.4 List configured input parameters ‘LiSt’
The ‘LiSt’ function enables the Device Address and
Variable Identity allocated to each lindicator 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 indicator
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
‘Adr: 00’ Device Address
‘id: 00’ Variable Identity
The display then automatically returns to the
selected BA648CF-F indicator input from where
another input may be selected.
If one of the eight BA648CF-F indicator’s inputs in-
1 to in-8 has not had a Device Address and
Variable Identity allocated to it, ‘LiSt’ will show both
as invalid address FF.
5.3.5 Enter address & display parameters
