Ci830 Fci; Address Switches; Profibus-Dp Connections - ABB S800 I/O Manual

Section 3 Configuration

CI830 FCI

The FCI needs to be connected to the PROFIBUS-DP and have an address selected.
It is also connected to a 24 V d.c. power source to provide power to the I/O Station.
Also refer to
estimate the fieldbus and power loading of each I/O station configuration.

Address Switches

The CI830 is equipped with two rotary switches used as station address selectors for
PROFIBUS-DP connection. The station address can be set in the range of 01 to 79.
There can be up to 32 stations per PROFIBUS-DP segment.

PROFIBUS-DP Connections

The FCI connects to the PROFIBUS-DP via 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-DP without disconnecting the other nodes of the fieldbus. 
If CI830 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 CI830 can not be done without disrupting the bus.
