Product Overview
The GE IC697CGR772 Central Processing Unit (CPU) is a specialized controller designed for the GE Fanuc Series 90-70 PLC platform. As the central processing component of an industrial automation system, the CPU executes the user application program, processes input information, manages control logic, and generates output commands for connected field equipment.
In a PLC-based automation system, the CPU acts as the primary decision-making component. Signals collected from sensors and input modules are processed according to the programmed control logic. The resulting commands are then transferred to output modules, drives, actuators, and other control devices.
The IC697CGR772 is designed for applications requiring dependable PLC processing within industrial environments. It can form part of a larger control architecture containing I/O modules, communication interfaces, power supplies, operator interfaces, and distributed automation equipment.
Its role is especially important in applications where continuous and predictable control processing is required, including manufacturing equipment, machine automation, process systems, material handling, and other industrial control installations.

Function and Working Principle
The main function of the GE IC697CGR772 is to execute the PLC control program and coordinate the operation of the connected automation system.
The CPU receives information from input devices and I/O modules. It processes this information according to the application logic stored in the controller and then generates appropriate commands for output devices.
A simplified PLC control cycle can be represented as:
Field Sensors → Input Modules → IC697CGR772 CPU → Output Modules → Actuators
During normal operation, the CPU repeatedly performs control-processing tasks.
These tasks can include:
- Reading input states
- Processing programmed logic
- Executing control sequences
- Updating output commands
- Monitoring system status
- Processing internal variables
- Managing communication tasks
- Handling diagnostic information
- Coordinating connected automation equipment
The CPU therefore serves as the central processing point of the PLC system.
For example, a production machine may use sensors to detect the position of a product. The input module transfers this information to the CPU. The IC697CGR772 processes the signal according to the programmed sequence and then commands an output device to operate a motor, valve, cylinder, or other actuator.
This continuous processing cycle allows the automation system to respond to changing process conditions.
Role in Industrial Control Systems
The IC697CGR772 serves as the central control processor in a compatible Series 90-70 PLC architecture.
A complete system can contain:
- Series 90-70 CPU
- PLC power supply
- Main PLC rack
- Digital input modules
- Digital output modules
- Analog input modules
- Analog output modules
- Communication modules
- Interface modules
- Remote I/O
- Human Machine Interface (HMI)
- Industrial drives
- Sensors and actuators
The CPU coordinates these components by executing the application program and managing the flow of control information.
For a distributed automation system, the CPU may receive information from several I/O areas while simultaneously exchanging information with other system components.
This makes the processor one of the most important components in the PLC architecture.
Industrial Applications
The GE IC697CGR772 can be used in a variety of industrial automation applications where Series 90-70 PLC control processing is required.
Manufacturing Automation
Production lines require coordinated control of sensors, conveyors, motors, actuators, and inspection equipment. The CPU processes the machine logic required to synchronize these operations.
