1. DESCRIPTION

The BA448CF-F fieldbus indicator is an intrinsically
safe 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
BA448CF-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 BA448CF-F fieldbus indicator has
an IP66 front panel and is supplied with a gasket to
seal the joint between the instrument and the
panel.

The instrument is intrinsically safe and has been
certified by European Notified Body Intertek
Testing and Certification Ltd (ITS) to harmonised
ATEX explosive gas standards, which has been
used to confirm compliance with European ATEX
Directive 94/9/EC.

The BA448CF-F 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-F
fieldbus indicator has IECEx intrinsic safety
approval – see Appendix 2.

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 certification label. There is an
alternative version of the fieldbus display, order
code BA448CF-P for use on PROFIBUS PA
networks.

4. SYSTEM DESIGN FOR HAZARDOUS
AREAS

4.1 FISCO Systems

The BA448CF-F 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-F
Fieldbus Indicator has a higher voltage entity
intrinsic safety input parameter allowing connection
to a wide range of fieldbus segments.

The BA448CF-F 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-F Fieldbus Indicator is zero and the
equivalent inductance is insignificant. Therefore
these BA448CF-F safety parameters do not need
to be considered.

5. INSTALLATION

5.1 Location

The BA448CF-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
BA448CF-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.

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-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 BA448CF-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 BA448CF-F push
buttons are identified P E ▼ ▲ and legends
displayed by the fieldbus indicator are shown
within inverted commas e.g. ‘CodE’ and ‘LiSt’.

6.1 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
BA448CF-F indicators are supplied as fieldbus
nodes 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

6.3 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 BA448CF-F
listener are not known.

In the ‘SCAn’ function pressing the P button
causes the BA448CF-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 pre­determined 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 P button will preview the value of the data at
each selected address, if required it may then be
allocated to one of the eight BA448CF-F listener
inputs in-1, to in-8 by operating the P button 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 BA448CF­F 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.

6.3.1 Access

Access to the listener configuration menu is
obtained by operating the P and E buttons
simultaneously. If the BA448CF-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 P will allow the four digit security code to
be entered digit by digit using the ▼ or ▲ button to
adjust the flashing digit and P to move control to
the next digit. When the correct code has been
entered, pressing E will 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 6.2.2 to change it
to a fieldbus listener.

6.3.3 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 BA448CF-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 BA448CF-F Fieldbus indicator inputs.

The BA448CF-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 pre­viewed, 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 P which 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 BA448CF-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 BA448CF-F listener
inputs in-1 to in-8.

To select the required listener input press P to
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 E will 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.

6.3.4 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 P which will display the indicator
input currently selected in the display mode, other
inputs may be selected using the ▼ or ▲ button.
Operating the P button 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 BA448CF-F indicator input from where
another input may be selected.

If one of the eight BA448CF-F indicator’s inputs in­1 to in-8 has not had a Device Address and
Variable Identity allocated to it, ‘LiSt’ will show both
as invalid address FF.

7.2 Fault finding after commissioning
ENSURE PLANT SAFETY BEFORE

STARTING MAINTENANCE

Live maintenance is permitted on
intrinsically safe equipment installed in a
hazardous area, but only certified test
equipment should be used unless a gas
clearance certificate is available.

If a BA448CF-F fails after it has been functioning
correctly, the table shown in section 7.1 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.

7.3 Servicing

We recommend that faulty BA448CF-F Fieldbus
indicators are returned to BEKA associates or to
our local agent for repair.

7.4 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.

7.5 Guarantee

Instruments which fail within the guarantee period
should be returned to BEKA associates or our local
agent. It is helpful if a brief description of the fault
symptoms is provided.

7.6 Customer comments

BEKA associates is always pleased to receive
comments from customers about our products and
services. All communications are acknowledged
and whenever possible, suggestions are
implemented.
