overview：
CI856K01 is a communication interface module between ABB AC800M controller and S100 I/O system, which is part of ABB Industrial IT 800xA or Advant Controller 800M system. It is installed through Baseplate TP856 to realize data exchange between AC800M and S100 I/O modules, suitable for industrial automation and process control applications. The interface mainly consists of two parts,The following is a detailed description of the CI856K01 interface.
CI856 communication interface:
Powered by the processor unit through the CEX bus, no additional external power supply is required.
It supports hot swapping, which has the advantage of reusing most existing I/O installations (such as terminals and field wiring in existing ABB Master and Advant OCS installations).
It uses a 9-pin Sub_D connector, supports the Profibus DP protocol, and has 4000V lightning protection, 1.5A overcurrent and 600W surge protection.
TP856 base plate:
It is equipped with a ribbon connector and can be connected to the bus expansion board in the S100 I/O rack, providing DIN rail mounting. A CI856 can connect to up to 5 S100 I/O racks, and each I/O rack can accommodate up to 20 I/O boards.
Fuctions & Features:
- One S100 I/O port is provided (36-pin centerline micro ribbon connector on the TP856 backplane).
- The CI856 handles I/O scanning and updating for S100 I/O units in up to five I/O racks. The minimum cyclic scan/update interval is 0.2 milliseconds, but this depends on the I/O type and number of I/O points.
- A preset two-letter Alpha code lockout is installed on the base of the unit to prevent installation of incompatible components.
