Communications - AC 800M Communication interfacesCI873A

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, 6.1.1 and subsequent versions. The CI873A support 6 redundant pairs of CI873A from 5.1 FP4.
