GE 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:

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.

Four LEDs are located at the top of the board.  The Restart pushbutton is located immediately

below the LEDs.  The RS-232 serial port with the RJ-11 connector is the Station Manager port.

The RS-485 serial port with the 15-pin D connector located below the Station Manager port is the

module’s Downloader port.  The 14-pin AAUI connector, facing downward, is the Transceiver

port.  The Default MAC Address label is attached to the outside of the plastic housing.

Board Indicators

There are four LEDs on the Ethernet Interface:  OK, LAN, SER, and STAT.  These LEDs can be

ON, OFF, BLINKING slow, or BLINKING fast.  They indicate the state the Interface is in, traffic

on the Transceiver port and Downloader port, and when an exception event has occurred.

Restart Button

The Restart button serves four functions:  LED test, Restart, Restart and Reload, and Restart and

Enter Maintenance Utility.  The Restart button is inaccessible when the front cover of the Ethernet

Interface is closed.

Serial Ports

There are two serial ports on the Ethernet Interface:  the Station Manager Port and the Downloader

Port.

The Station Manager Port.  This RS-232 port is used to connect a terminal or terminal emulator

to access the Station Manager software on the Ethernet Interface.  This port uses a  6-pin, RJ-11

connector.  The IC693CBL316 Station Manager cable is ideal for connecting to this port (see

Chapter 10 for details).

The Firmware Upgrade Port.  The 15-pin, D-type, RS-485 port is used to connect to the PC

Downloader in case the communications software in the Ethernet Interface needs to be updated.

Use the IC690ACC901 miniconverter/cable kit for this connection (see Appendix E for details).
