ABB CI873A COMMUNICATIONS - AC 800M COMMUNICATION INTERFACES

The CI873A is an AC 800M communication interface that connects to external Ethernet devices using the EtherNet/IP protocol. The TP867 Baseplate has two RJ45 Ethernet connectors, but only the CH1 connector that supports 100Mbps is used. 

The CI873 expansion unit contains the CEX-Bus logic, a communication unit, and a DC/DC converter that supplies the required voltage from +24 V supply through the CEX-Bus. The CI873A module will only work with System 800xA 6.0.3.3, 6.1.1 and subsequent versions. 

The CI873A support 6 redundant pairs of CI873A from 5.1 FP4. Features and benefits Supports Ethernet/IP and Device Net protocols Support 6 redundant pairs of CI873A from 5.1 FP4

Control functions

The control functions are used to indicate the status of switching devices, 

i.e. circuit breakers and disconnectors, and to execute open and close commands for controllable switching devices of the switchgear. 

Furthermore, there are supplementary functions for control logic purposes, e.g. on/off switches, 

MIMIC alarm LED control, numerical data for MIMIC and logic controlled control position selector. 

The control functions configured with the Relay Configuration Tool can be associated with object status indicators that 

are part of the MIMIC configuration picture displayed on the HMI. 

The object status indicators are used to indicate the status of switching devices via the MIMIC picture and to control them locally.
