Repair GE-Emerson IC693CMM321 Ethernet Interface Module

The GE-Emerson IC693CMM321 Ethernet Interface Module provides an interface that allows the user to attach the Series 90-30 PLC to an Ethernet LAN via an external transceiver and AAUI cable, and to communicate with hosts and other control devices on the network. 

The Ethernet Interface for the Series 90-30 PLC has client/server capability. As a client, it can initiate communications with other PLCs containing Ethernet Interfaces. This is done from a ladder program using the COMMREQ Function Block. As a server, it responds only to requests from other devices such as a Host computer running a Host Communications Toolkit application or another Series 90-30 PLC acting as a client.

The base Ethernet Interface Module communicates via an external transceiver port on the bottom of the module, and an AAUI cable.
