The GE Fanuc IC693CMM321 is a Series 90-30 Ethernet Interface module that connects a PLC rack to an Ethernet LAN for communication with HMIs, SCADA systems, programming software, and other control devices. It supports client/server communication through SRTP and can handle multiple simultaneous connections.

 

Product Introduction

The GE Fanuc IC693CMM321 provides Ethernet communication capability for Series 90-30 PLC systems that do not have built-in network connectivity. It allows PLC data exchange with supervisory systems, engineering workstations, other PLCs, and industrial network devices through TCP/IP communication.

The module operates as both a client and server. In client mode, the PLC ladder program can initiate communication requests to other Ethernet-enabled controllers. In server mode, it responds to requests from host computers, HMIs, programming tools, or other PLC systems.

The IC693CMM321 is widely used in legacy Series 90-30 installations where maintaining existing Ethernet communication architecture is required. Typical applications include SCADA connectivity, production data collection, remote diagnostics, and PLC-to-PLC communication.

Installation & Configuration Guide

 

Stage 1: Pre-Installation Preparation (Approx. 15 minutes)

⚠️ Safety First

  • Notify operations before replacing the Ethernet interface module.
  • Confirm network communication requirements with the control system owner.
  • Place critical processes into a safe operating state.
  • Remove PLC rack power before removing the module.

Tools Required

  • ESD wrist strap
  • Phillips screwdriver
  • Laptop with PLC programming software
  • Ethernet cable
  • Network documentation

Data Backup

Before replacement:

  1. Record the existing Ethernet IP configuration.
  2. Document subnet mask and gateway settings.
  3. Record PLC rack slot location.
  4. Save hardware configuration files.
  5. Record station manager settings.
  6. Photograph network connections.

 

Stage 2: Removing the Existing Module (Approx. 10 minutes)

Steps:

  1. Disconnect Ethernet and serial communication cables.
  2. Switch off PLC rack power.
  3. Remove the module retaining clip.
  4. Carefully remove the IC693CMM321 from the rack.
  5. Inspect the rack connector for contamination or damage.

⚠️ Important:
Do not discard the original module configuration information. Network parameters must be transferred to the replacement unit.

 

Stage 3: Installing IC693CMM321 (Approx. 20 minutes)

Steps:

  1. Wear an ESD wrist strap.
  2. Verify replacement model number: .
  3. Install the module into the correct Series 90-30 rack slot.
  4. Reconnect Ethernet network cable.
  5. Reconnect Station Manager or loader connections if required.
  6. Restore PLC rack power.

Configuration Checklist

  • IP address verified
  • MAC address recorded
  • Ethernet cable connection checked
  • SRTP configuration restored
  • PLC communication parameters verified

 

Stage 4: Commissioning & Testing (Approx. 30 minutes)

Pre-Test Check

  • Confirm Ethernet link status.
  • Verify PLC CPU compatibility.
  • Check network addressing.

Testing Procedure

  1. Power up the PLC rack.
  2. Confirm module OK LED.
  3. Verify LAN communication indicator.
  4. Connect programming software.
  5. Test PLC-to-PC communication.
  6. Verify HMI or SCADA communication.
  7. Confirm data exchange with remote devices.

⚠️ Troubleshooting Note

If Ethernet communication fails:

  • Verify IP address configuration.
  • Check Ethernet cable and network switch port.
  • Confirm CPU firmware compatibility.
  • Verify SRTP settings.
  • Check module LED diagnostic status.

 

Frequently Asked Questions (FAQ)

Q1: Is the GE Fanuc obsolete?

Yes. The belongs to the discontinued Series 90-30 PLC family. Replacement units are typically sourced through new surplus, tested used, or refurbished automation inventory channels.

Q2: What is the main function of ?

The module provides Ethernet communication capability for Series 90-30 PLC systems, allowing connection to HMIs, SCADA systems, programming tools, and other Ethernet-enabled controllers.

Q3: Does support Ethernet TCP/IP communication?

Yes. The module provides TCP/IP Ethernet communication and supports SRTP client/server functions for industrial data exchange.

Q4: How many devices can connect to ?

The module supports up to 16 simultaneous server connections when operating with compatible CPU firmware.

Q5: Can be installed in any Series 90-30 rack?

Yes, the module is designed as a single-slot Series 90-30 communication module. However, verify CPU compatibility and firmware requirements before installation.

Q6: What communication ports are available on ?

Depending on hardware revision, the module provides Ethernet connectivity through AAUI and/or 10Base-T interfaces, along with RS-232 Station Manager and RS-485 loader communication ports.

Q7: What should be verified before ordering ?

Confirm:

  • Exact part number:
  • PLC platform: GE Fanuc Series 90-30
  • Ethernet interface type
  • Hardware revision
  • CPU firmware compatibility
  • Existing IP configuration
  • Required condition: New Original, New Surplus, or Tested Refurbished

For legacy Series 90-30 Ethernet replacement projects, network parameters and firmware compatibility are as important as the physical module match. A replacement communication module with incorrect settings can prevent PLC network recovery even when the hardware is correct.
