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.

Documentation

This instruction manual describes installation,
configuration and use of the BA644DF-P as a
PROFIBUS PA listener and as a PROFIBUS PA
node.    For additional node configuration
information please refer to the 

BEKA PROFIBUS

PA Display – Fieldbus Interface Guide

 which is

available from the BEKA sales office, or may be
downloaded from www.beka.co.uk

2.  OPERATION

The BA644DF-P indicator can display up to eight
pre-configured PROFIBUS PA 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

‘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 BA644DF-P PROFIBUS PA indicator is
powered and communicates 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 PROFIBUS PA segment that can supply an
additional 13mA at between 9 and 32V required to
power the instrument.
