Product Overview
The GE IC697CPU771RR is a high-performance central processing unit (CPU) module from GE Fanuc’s Series 90-70 PLC platform, designed for robust industrial automation control systems. Utilizing an 80C186 microprocessor clocked at 12 MHz and equipped with 32 KB memory, this module delivers rapid Boolean instruction execution (0.4 μs) and supports real-time control of complex machinery. It seamlessly integrates into VME-based PLC racks, managing up to 512 discrete I/O points and 8,000 analog I/O points while communicating via RS-485/422 serial protocols. The absence of physical DIP switches or jumpers allows configuration entirely through software (e.g., Windows-based Proficy ME), enhancing reliability in vibration-prone environments. As a core component in GE’s 90-70 series, the IC697CPU771RR ensures operational stability through battery-backed memory (lithium battery IC697ACC701) and configurable security features, making it ideal for mission-critical applications requiring uninterrupted automation.

Key Features and Benefits
High-Speed Processing & Precision Control
The GE IC697CPU771RR executes Boolean logic in 0.4 μs, enabling real-time responsiveness for high-speed production lines and robotic systems. Its floating-point arithmetic support handles complex analog calculations, critical for precision tasks like CNC machining.
Secure and Flexible Configuration
Password-protected access prevents unauthorized modifications, while software-based setup eliminates error-prone physical switches. Three front-panel LEDs provide instant status diagnostics (Run/Fault/Battery), reducing troubleshooting time.
Robust Integration and Durability
Compatible with GE’s VME C.1 standard, the module interfaces seamlessly with peripheral I/O modules (e.g., analog IC697ALG440 or discrete IC697MDL250). Its industrial-grade design withstands contaminants (IP20-rated) and operates in 0–60°C environments, ensuring reliability in factories and power plants.
Scalable Memory and Backup
Battery-backed RAM retains program data during outages, while modular memory expansion (via IC697MEM717) supports large-scale control algorithms without hardware upgrades.
Application Areas
The IC697CPU771RR excels in sectors demanding reliability and scalability:
- Manufacturing: Controls automotive assembly lines (e.g., welding robots) and semiconductor production, leveraging high I/O density for sensor-actuator networks.
- Energy & Utilities: Manages turbine control systems and power distribution grids, utilizing analog I/O for real-time pressure/temperature monitoring.
- Infrastructure: Coordinates water treatment plants and traffic control systems, with serial communication enabling SCADA integration.
- Building Automation: Optimizes HVAC and elevator control in smart buildings through rapid discrete signal processing.
