The Ethernet Interface module (IC693CMM321) provides an interface that allows you 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 the

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 Ethernet Interface allows you to:

Directly attach your PLC to an Ethernet network

Initiate transfer of data to the PLC from another device

Communicate simultaneously to multiple devices with up to 16 server connections

Interface with other GE Fanuc devices, as well as with devices from other vendors

Communicate from a Host computer (or other control device)

Diagnose and maintain your system using diagnostic and station management tools

The Ethernet Interface does not support the Series 90-30/20/Micro Hand-Held Programmer.  Either

one or two Ethernet Interface modules can be installed in any Series 90-30 baseplate.

The Ethernet Interface connects to an Ethernet network through an external SQE enabled

transceiver (GE Fanuc catalog no. IC649AEA102 or IC649AEA103 or equivalent.  See Appendix

J).  The following figure shows the layout of the Ethernet Interface.
