Product Overview
The GE IC693CMM321-EF is a Series 90-30 Ethernet Interface Module used to connect a GE Series 90-30 PLC system with Ethernet-based industrial devices. It handles the communication interface required when PLC data needs to be exchanged with supervisory computers, operator interfaces, engineering workstations, or other compatible network equipment.
The module is suited to Series 90-30 installations where controller information needs to be accessed beyond the local PLC rack. Typical data includes equipment status, process values, control information, diagnostic information, and application data exchanged between the PLC and higher-level systems.
In a manufacturing line, the IC693CMM321-EF can be used for PLC-to-supervisory communication. In a water treatment installation, it can support the transfer of controller information to a monitoring system. In a machine-control application, Ethernet communication can connect the Series 90-30 controller with an HMI or engineering workstation.
For replacement work, technicians should verify the complete model number, existing PLC configuration, communication settings, network arrangement, and connected software before removing an existing module.

Working Principle
The IC693CMM321-EF handles Ethernet communication between the Series 90-30 PLC and connected network devices.
Series 90-30 PLC → IC693CMM321-EF → Ethernet Network → External Device
The Series 90-30 CPU generates application data through the execution of the PLC program. The Ethernet interface handles the network communication associated with the configured application. Ethernet-connected equipment exchanges the required information with the PLC through the network connection.
Typical communication data can include:
- PLC status information
- Equipment operating states
- Process-related data
- Control commands
- Diagnostic information
- Application data required by supervisory systems
The communication path depends on the PLC configuration, network arrangement, connected equipment, and software used by the application.
