GE IC693CMM321-JK Ethernet Interface Module

FAQ

Q1: What is the GE Fanuc IC693CMM321-JK used for?
The IC693CMM321-JK is used to add Ethernet communication capability to Series 90-30 PLC systems. It enables data exchange between PLCs, engineering computers, HMIs, and industrial control networks.

Q2: What communication protocols does the IC693CMM321-JK support?
The module supports TCP/IP-based Ethernet communication, including GE Fanuc SRTP protocol for PLC communication. Certain firmware versions of the IC693CMM321 family also support Modbus/TCP functions.

Q3: How many devices can communicate with the IC693CMM321-JK at the same time?
The module supports up to 16 simultaneous server connections, allowing multiple external devices such as HMIs, computers, and other PLCs to access PLC data.

Q4: What Ethernet connection method does the IC693CMM321-JK use?
The IC693CMM321-JK connects to Ethernet networks through an AAUI port with an external transceiver and cable. Later revisions of the IC693CMM321 family added direct 10Base-T RJ-45 connectivity.

Q5: Can the IC693CMM321-JK work as both a client and a server?
Yes. As a client, the module can initiate communication with other Ethernet-enabled PLCs through ladder logic COMMREQ instructions. As a server, it responds to requests from external devices.

Q6: What diagnostic functions are available on the IC693CMM321-JK?
The module provides Ethernet diagnostics and Station Manager functions for monitoring communication status, troubleshooting network problems, and maintaining the Ethernet interface.

Q7: What does the “JK” revision indicate?
The “JK” suffix identifies the hardware and firmware revision level of the IC693CMM321 Ethernet Interface module. The JK revision belongs to the earlier revision series before later updates such as JL, KL, KM, and KN.

Q8: What should be checked before replacing an IC693CMM321-JK module?
Before replacement, verify the Series 90-30 PLC compatibility, CPU firmware requirements, Ethernet network configuration, IP parameters, communication protocol settings, and existing PLC project configuration to ensure proper network operation after installation.
