handbookProduct-CI856
S100 I/O communication is realized in AC 800Mbycommunication
interface CI856,which is connected to the CEX-Bus through a base
plate. The baseplate, TP856, houses a ribbon connectorconnecting
to bus extender boards in S100 I/O racks and provides a simple DIN
rail mounting. Up to five S100 I/O racks can be connected to one
CI856 where each I/O rack can hold up to 20 I/O boards.
The CI856 is powered bythe processor unit,via the CEX-Bus, and
therefore does notrequire any additional external power source.
Features and benefits
A key benefitwith the CI856 interface is the possibilityto reuse the majority of the existing I/O
installation, including terminations and fieldwiring in existing ABBMaster and AdvantOCS
installations.
Single connection to S100 I/O units located in up to five I/O racks
Code locking device to prevent mounting of incompatible components
Hot swap functionality
