Product Overview
The GE IC697CPU780RR is a high-reliability central processing unit (CPU) module from GE Fanuc’s Series 90-70 PLC platform (now under Emerson Automation), designed for mission-critical industrial automation systems. Utilizing an 80386DX microprocessor clocked at 16 MHz, this module delivers rapid Boolean instruction execution (0.4 μs) and robust real-time control for complex machinery. It supports hot standby redundancy, enabling seamless failover between primary and backup CPUs within 20 ms to eliminate single points of failure in environments like power plants or steel mills. Integrated with RS-485 serial communication and battery-backed memory (IC697ACC701), the IC697CPU780RR manages up to 12K discrete I/O points and 8K analog I/O points, ensuring zero downtime for large-scale automation systems.
As a core component of GE’s 90-70 series, the IC697CPU780RR operates in a single PLC chassis slot with a 5V DC backplane supply (1.6A current draw). Its software-configurable design via Proficy ME eliminates physical DIP switches, enhancing stability in high-vibration environments. The module’s extended temperature range (-40°C to +70°C) and IP20-rated housing ensure reliability in harsh industrial settings.

Key Features and Benefits
Hot Standby Redundancy & Fault Tolerance
The GE IC697CPU780RR provides automatic failover within 20 ms during primary CPU failure, leveraging synchronized data and one-scan switching to prevent system downtime in nuclear plants or high-speed production lines.
High-Speed Processing & Scalability
With 0.4 μs Boolean execution and floating-point arithmetic support, it handles complex algorithms for CNC machining or robotic control. Expandable memory (512 KB RAM) accommodates large-scale programs without hardware upgrades.
Industrial Robustness
IP20-rated housing resists dust and contaminants, while its wide temperature tolerance (-40°C to +70°C) ensures stability in foundries or outdoor substations. Software-based configuration reduces manual errors.
Integrated Diagnostics
Four front-panel LEDs monitor CPU status (Run/Fault/Battery/Output Enable), enabling rapid troubleshooting. Battery-backed RAM retains data during outages for up to 6 months.
Application Areas
- Heavy Industry: Controls steel mill rolling lines and blast furnaces, leveraging high I/O density for sensor networks and redundancy for continuous operation.
- Energy & Utilities: Manages turbine control systems (e.g., nuclear or thermal plants) and power grids, utilizing analog I/O for real-time pressure/temperature monitoring.
- Manufacturing: Optimizes automotive assembly lines and semiconductor fabrication with fail-safe logic for robotic welding arms.
- Infrastructure: Coordinates water treatment pumps and smart building HVAC systems via RS-485/SCADA integration.
