ABB CI856K01 3BSE026055R1 Fieldbus communication interface module

Description

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 for Advant Fieldbus 100 fully redundant communication
• CI830 for PROFIBUS-DP
• 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 SD821/SD822/SD823 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, together with the interconnection unit TB815, is used when a fully redundant
configuration is required. CI820 comprises the Advant Fieldbus 100 twisted pair
connection and TB815 the Optical ModuleBus connection.
CI830 has a 9 pin D-sub connector and modems for PROFIBUS-DP and a
connection for the Optical ModuleBus.
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 passthrough. HCIR makes it possible to change the I/O station configuration without
stopping the I/O station execution.
