Profibus Connection - ABB S800 I/O Manual

PROFIBUS Connection

PROFIBUS Connection
The FCI connects to the PROFIBUS through the 9 pin D-way connector on the
front. This allows the FCI (if not the last one at the PROFIBUS segment) to be
removed from the PROFIBUS without disconnecting the other nodes of the
fieldbus.
If CI801 is the last module at a PROFIBUS segment and supplies an active
termination in the cable connector, disconnection of the power supply or the
PROFIBUS cable from CI801 can not be done without disrupting the bus.
