Product Overview
The GE IC693CMM311N is a Series 90-30 Communications Coprocessor Module used to add dedicated communication functions to a GE Series 90-30 PLC system. It handles communication tasks that would otherwise need to be managed directly by the main PLC processor, making it suitable for control architectures that require additional data exchange with external equipment.
The module can be used in applications where the Series 90-30 controller needs to communicate with other automation devices, supervisory systems, or intelligent equipment. Communication data may include controller information, equipment status, production data, and other application-specific information.
In a manufacturing system, the IC693CMM311N can support communication between the PLC and external automation equipment. In a process-control installation, it can be used where controller information must be exchanged with other parts of the control system.
For replacement work, engineers should verify the complete module number, PLC rack configuration, communication requirements, existing software configuration, and connected devices before installation.

Working Principle
The IC693CMM311N handles communication-related processing within the Series 90-30 control system.
Series 90-30 CPU → IC693CMM311N → Communication Network / External Device
The PLC controller manages the main application logic and generates the data required for external communication. The communications coprocessor processes the applicable communication tasks and exchanges data with connected equipment according to the configured system arrangement.
Typical information can include:
- Controller data
- Equipment status
- Production information
- Control-related information
- Communication status
- Application data
The communication sequence depends on the configured Series 90-30 application and the external devices connected to the system.
Role in a Series 90-30 Control Architecture
The IC693CMM311N operates within the communication layer of the Series 90-30 PLC architecture.

Technical FAQs
What is the purpose of the GE IC693CMM311N Communications Coprocessor Module?
The IC693CMM311N handles communication-related processing within a Series 90-30 PLC system. It supports data exchange between the PLC architecture and compatible external automation equipment according to the configured application.
How does a communications coprocessor differ from the main Series 90-30 CPU?
The CPU executes the primary PLC control program, while the communications coprocessor handles designated communication functions. Separating these tasks can help the control application and communication processing operate as distinct functions within the PLC architecture.
What should be checked when an IC693CMM311N communication function stops working?
The engineer should check the PLC configuration, module status, communication settings, physical connections, external network equipment, and the connected device. Reviewing the communication path from the Series 90-30 system to the remote equipment can help identify whether the fault is related to hardware, configuration, or the network.
Is the IC693CMM311N suitable for maintaining an existing Series 90-30 control system?
It can be considered for maintenance or replacement work involving compatible Series 90-30 communication architectures. Before installation, the existing controller configuration, communication requirements, software, connected equipment, and module compatibility should be verified.
