Product Overview
The GE IC697CMM711 Communication Coprocessor Module is a specialized communication component designed for the GE Fanuc Series 90-70 programmable logic controller platform. It provides communication-processing capabilities that allow the PLC control system to exchange information with compatible external devices, controllers, computers, and industrial networks.
In a modular industrial automation architecture, communication is essential for connecting the PLC with supervisory systems, operator interfaces, programming workstations, other controllers, and networked equipment. The IC697CMM711 is designed to support this communication layer while allowing the main PLC processor to concentrate on control logic and real-time automation tasks.
The module is installed as part of the Series 90-70 rack-based architecture and works together with the PLC CPU, power supply, I/O modules, communication cabling, and connected external systems.
The specified dimensions of the IC697CMM711 are approximately 233 × 41 × 175 mm, while the specified weight is approximately 0.51 kg.
As a communication coprocessor, the module should not be confused with a standard digital or analog I/O module. Its primary purpose is communication processing and system connectivity rather than direct control of field devices.
The IC697CMM711 can therefore be an important component in legacy Series 90-70 installations where reliable communication between PLC equipment and external automation systems is required.

Function and Working Principle
The main function of the IC697CMM711 is to provide dedicated communication-processing capability within a Series 90-70 PLC system.
A simplified communication architecture can be represented as:
PLC CPU → IC697CMM711 → Communication Network → External Device / Computer / Controller
The PLC CPU is responsible for executing the main application program.
The communication coprocessor handles communication-related processing according to the supported system configuration. This separation can reduce the communication-processing burden on the main controller and provide a dedicated interface for exchanging data with external equipment.
Depending on the application, communication data can be used for:
- Production monitoring
- PLC-to-PLC data exchange
- Supervisory control
- Operator interface communication
- Engineering access
- Equipment status monitoring
- Process data exchange
- Remote system integration
The communication module receives or transmits data through the appropriate communication interface and works with the PLC system to make the information available to the application.
This allows data generated by the PLC to be transferred to other systems while information from external devices can be made available to the control system.
Role in Industrial Control Systems
The IC697CMM711 provides the communication layer between the Series 90-70 control system and external automation equipment.
A typical architecture can be represented as:
Field Devices → I/O Modules → PLC CPU → Communication Coprocessor → Supervisory / External Systems
The communication coprocessor can support data exchange between the PLC and external systems such as:
- Operator interfaces
- Supervisory computers
- Other PLC controllers
- Engineering workstations
- Industrial communication systems
- Manufacturing management systems
- Monitoring equipment
This architecture allows the PLC to operate as part of a larger automation environment rather than as an isolated controller.
For example, a PLC can control a production machine locally while simultaneously exchanging operating information with a supervisory computer.
The communication module therefore contributes to both system integration and operational visibility.
Industrial Applications
Manufacturing Automation
The IC697CMM711 can be used in manufacturing environments where PLC systems need to exchange information with other control or supervisory systems.
Applications may include:
- Production lines
- Assembly systems
- Packaging machinery
- Conveyor systems
- Automated material handling
- Production monitoring
Communication data can include machine status, production information, alarms, operating conditions, and control commands.
Process Control
Process-control systems frequently require communication between local controllers and higher-level monitoring systems.
The IC697CMM711 can form part of a suitable Series 90-70 communication architecture for transferring process information between the PLC and external systems.
Machine Automation
Industrial machines can use communication interfaces to exchange information with HMIs, engineering computers, production systems, or other controllers.
The communication coprocessor provides the necessary communication-processing role within the PLC architecture.
Supervisory Control
A PLC may need to communicate with supervisory computers that collect operational information or provide higher-level control functions.
The IC697CMM711 can support this type of system architecture when used with compatible communication hardware.
Data Acquisition
Industrial systems may collect information from multiple PLCs and transfer the information to a central monitoring or data-processing system.
Communication modules help create the required connection between local PLC controllers and centralized systems.
OEM Equipment
Machine manufacturers using Series 90-70 systems may incorporate communication modules to allow their equipment to exchange information with customer automation systems.
This can be useful for machine status monitoring, production data collection, and integration with plant-level systems.

Communication System Integration
The IC697CMM711 should be evaluated as one part of a complete industrial communication architecture.
A typical system can include:
Series 90-70 PLC → Communication Coprocessor → Network Interface → External Controller / Computer
The communication architecture can support the exchange of operational information between different levels of an automation system.
For example:
Field Level → PLC Control Level → Supervisory Level → Production Management Level
At the control level, the PLC processes field information and executes the control program.
The communication module provides the pathway for selected data to be exchanged with external systems.
This can improve system monitoring and allow production or process information to be centralized.
When integrating the module into an existing installation, engineers should maintain the original communication architecture whenever possible. Legacy PLC systems can contain established addressing, cabling, software, and supervisory configurations that must remain consistent.
