The GE Fanuc IC693CMM321 is an Ethernet Interface module. By implementing this module in a Series 90-30 PLC system, users can connect it to an Ethernet LAN. This is achieved through an AAUI cable and an external transceiver. This set-up enables the PLC system to communicate with hosts and also other control devices that are on the network. The IC693CMM321 interface module has both client and server capabilities. By using the ladder program through the COMMREQ Function Block, the module acts as a client to communicate with other PLCs that contain Ethernet interfaces. When acting as a server, the module only responds to requests. For example, it could respond to another Series 90-30 PLC acting as a client.
The Ethernet Interface module enables users to do a lot of things such as initiating data transfers from devices to the PLC and simultaneously communicating to multiple devices with up to a maximum of 16 server connections. The IC693CMM321 does have some limitations, however, as the module does not support the Hand-Held Programmer from any model in the Series 90-30, 20 or Micro range. Users can use the module with any series 90-30 system. One or two may be used together by installing them in the baseplate. There is a restart button on the module, which actually has multiple functions aside from just restarting. It can run an LED test, has a Restart and Reload mode as well as a function to Restart and Enter Maintenance Utility. Whenever the front door of the module is closed over, the Restart button cannot be accessed.
The IC693CMM321 module is an Ethernet interface module or TCP/IP
module manufactured by GE Fanuc Automation. This unit is part of
the Series 90-30 product line and it is engineered to allow the
Series 90-30 Programmable Logic Controllers (PLCs) to connect to
the Ethernet Local Area Network (LAN). The connection is made by
using the AAUI cable as well as the external transceiver and it
makes communication with the host devices possible as well as
communication with other control devices through the Ethernet
network possible. The GE Fanuc IC693CMM321 Ethernet interface
TCP/IP module is engineered for use as either a server device or
client device. This module serves as a client device while
initiating the communication connections of the GE Fanuc PLCs with
the Ethernet interfaces. It works as a server device while
responding to the requests from various connected devices. This
Ethernet interface unit responds to requests from PLCs that act as
either host computers or client devices and it uses the Host
Communication Toolkit application.
The GE Fanuc IC693CMM321 Ethernet interface module diagnoses and
maintains the PLC system, and it executes the transfer of data from
the PLC to the other devices. Additionally, this unit helps to
communicate with various devices concurrently and it supports up to
16 total server connections. The GE Fanuc Series 90-30 baseplate
allows for the installation of either 1 or 2 Ethernet interface
modules. However, these modules cannot be used with the GE Fanuc
handheld programmers in the Series 90-30, 20, and micro device
series. The IC693CMM321 module comes with 4 LED indicators and 2
ports which include the Station Manager port as well as the
Firmware Upgrade port. The LED indicators on this unit include the
“OK,” “LAN,” “SER,” and “STAT” LEDs.
