GE / IP FANUC Series 90/30 In Stock
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 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:
â– Directly attach your PLC to an Ethernet network
â– Initiate transfer of data to the PLC from another device
â– Communicate simultaneously to multiple devices with up to 16 server connections
â– Interface with other GE devices, as well as with devices from other vendors
â– Communicate from a Host computer (or other control device)
â– 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 catalog no. IC649AEA102 or IC649AEA103 or equivalent. See Appendix J).

Cannot Ping Series 90-30 Ethernet Card - IC693CMM321
Cannot Ping Series 90-30 Ethernet Card - IC693CMM321
Trying to connect a 90-30 PLC to an Ethernet LAN using the CMM 321 Ethernet Interface Module. Unable to connect to the PLC from the LAN. All IP parameters (IP address, subnet mask and default gateway) on the CMM321 are right, but when trying to "ping" to the PLC, it does not answer. The STAT LED on the module is always on.
What to look for:
With respect to the STAT LED - constant on is good, blinking indicates the module is waiting for new software, and off indicates an event has been recorded in the event log. Since the STAT LED is on (not blinking) the CMM321 thinks it has a good network connection (test frames were OK). The LAN LED should blink every time the CMM321 sends or receives a frame - watch this LED while pinging the module if the ping gets to the module at all the LAN LED should blink. Note the LAN LED will blink about once a minute as the module reconfirms its network connection by sending a test frame.
Possible reasons for a ping getting no response are:
IC693CMM321 Ethernet Module in Expansion Rack
The 90-30 Ethernet module, IC693CMM321, can be placed in an expansion rack.
There is a small reduction (10%) to the throughput of the module. Use of the module in a remote expansion rack is also possible but in that case the throughput is severely affected (80% reduction).
Troubleshooting Ethernet Communications with Station Manager Software Tool
Station Manager software, which resides in the firmware of the PLC Ethernet Interface products listed below
The Ethernet Interface enables Series 90 PLCs to communicate with other Series 90 PLCs, with GE programming software, and with computer applications developed using GE Ethernet protocols, such as CIMPLICITY- HMI. Refer to GFK-1541, TCP/IP Ethernet Communications for the Series 90 PLC User's Manual for information on installing and programming the Ethernet Interface.
