IC693CMM321 Ethernet Interface Module
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:
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 catalog no. IC649AEA102 or IC649AEA103 or equivalent. See Appendix
J). The following figure shows the layout of the Ethernet Interface.
