Fieldbus Communication Interface
A Fieldbus Communication Interface module is used as communication interface to
connect S800 I/O modules to the fieldbus.
There are five different FCI modules:
• CI801 – for PROFIBUS-DPV1
• CI810 – for Advant Fieldbus 100, with or without media redundancy
• CI820/CI820V1 – for Advant Fieldbus 100 fully redundant communication
• CI840 – for PROFIBUS-DPV1 fully redundant communication
They all have an isolated input for 24 V d.c. power (19.2 - 30 V). The power source
can be the SD831/ SD832/ SD833/ SD834 power supplies, battery, or other IEC664
Installation Category II power sources. Power status inputs, 2 x 24 V, to monitor 1:1
redundant mains are also provided.
CI801 has a 9 pin D-sub connector and modems for PROFIBUS-DPV1 and a
connection for the Optical ModuleBus via TB806/TB842.
CI810 has two connectors and modems for a media redundant Advant Fieldbus 100
twisted pair cables and a connection for the Optical ModuleBus.
CI820/CI820V1, together with the interconnection unit TB815, is used when a fully
redundant configuration is required. CI820/CI820V1 comprises the Advant Fieldbus
100 twisted pair connection and TB815 the Optical ModuleBus connection.
CI840, together with termination unit TU846/TU847, is used when a fully
redundant configuration is required. CI840 is mounted on TU846/TU847 and has a
connector for power supply and two 9 pin D-sub connectors for PROFIBUS-DPV1
connection. TU846/TU847 has two service ports and two address switches. CI840
also has a connection for the Optical ModuleBus via TB806/TB842 or
TB846/TB842.
CI801 and CI840 supports Hot Configuration in Run (HCIR) and HART pass-
through. HCIR makes it possible to change the I/O station configuration without
stopping the I/O station execution.
The front plate of the communication modules provides LEDs for diagnostic and
status indications. Two rotary switches are provided for setting of the I/O station
address. No other addresses are required to be set within the I/O station. Labels for
