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.
