GE IC693CMM321-CC Ethernet Interface Module

The GE Fanuc IC693CMM321-CC, also cataloged as the IC693CMM321 Ethernet Interface Module, operates as a dedicated hardware component for deterministic TCP/IP industrial network communications within GE Fanuc Series 90-30 PLC platforms. Occupying a single baseplate slot, it bridges CPU logic memory to external Ethernet networks via three physical interface ports and supports up to 16 server connections.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The GE Fanuc IC693CMM321-CC routes high-speed Ethernet packets directly across the Series 90-30 parallel backplane bus, transferring data arrays between the local host processor and connected network nodes without extending user scan time. Firmware flash compatibility determines operational performance based on host CPU revisions: running on CPU v6.50 or higher unleashes full multi-client capacity across 16 server connections, whereas earlier CPU builds (v5.03 through v6.04) limit execution to a single SRTP connection. Optical and galvanic isolation circuits shield the module's internal microcontrollers against external high-voltage line surges and ground loops.

Frequently Asked Questions

Q: What physical hardware is required to establish network cabling connections on the IC693CMM321-CC?

A: The IC693CMM321-CC utilizes an AAUI port requiring an external transceiver (such as 10Base-T or 10Base-FL) and an AAUI interface cable to attach to physical network cabling.

Q: Can the IC693CMM321-CC be inserted into or extracted from the rack while backplane power is turned on?

A: No. The Series 90-30 baseplate architecture does not support live module insertion or removal (hot-swapping). The baseplate power supply must be shut off prior to installing or removing the module.

Q: How does CPU firmware version impact the server connection capacity of the IC693CMM321-CC?

A: Host CPU firmware versions 6.50 or higher support the maximum limit of 16 server connections. Firmware versions 5.03 to 6.04 restrict the module to a single active SRTP connection.

Field Installation Guidelines

1. Disconnect main operating power from the Series 90-30 baseplate prior to placing or removing the module.
2. Select an available baseplate option slot (slots 2 through 10 on CPU baseplates or expansion racks).
3. Insert the top pivot hook of the IC693CMM321-CC module into the top slot notch of the baseplate.
4. Swing the module down and press firmly until the bottom baseplate connector latch clicks into place.
5. Attach the required AAUI cable or external transceiver to the front communication port and secure hardware strain relief.
6. Re-apply system power, observe the four front panel LEDs for diagnostic initialization, and download network parameters via Machine Edition.
