GE IC697CPU781 Product Specification
Product Overview
The GE IC697CPU781 is a high-performance CPU module engineered for GE’s Series 90-70 PLC platform, serving as the processing core for industrial automation systems in manufacturing, power generation, and process control. As the central command unit of the Series 90-70 architecture, this module executes complex control logic, manages I/O modules, and coordinates communication with external devices, ensuring precise and reliable operation in mission-critical applications.
Integrated into the Series 90-70 system, the GE IC697CPU781 features a 32-bit RISC processor with a clock speed of 100 MHz, delivering fast execution of ladder logic, structured text, and function block diagrams—up to 5,000 instructions per millisecond. Its robust design includes 512 KB of user memory and 2 MB of non-volatile flash memory for program storage, ensuring data retention during power outages. The module supports genius bus communication for seamless integration with Series 90-70 I/O modules, as well as RS-232 and RS-485 ports for connecting HMIs, printers, and other peripherals.
The GE IC697CPU781’s compact form factor (114 mm × 229 mm × 152 mm) and rugged construction—including a conformal coating and IP20-rated enclosure—enable reliable operation in temperatures ranging from 0°C to 60°C, with resistance to vibration (10–2000 Hz, 10 G rms) and humidity (5–95% non-condensing). Front-panel LEDs provide real-time status monitoring for power, run mode, and communication, simplifying troubleshooting. Compatibility with GE’s Proficy PLC Programming Software allows easy configuration of control logic, while its support for hot standby redundancy (when paired with a second GE IC697CPU781) ensures uninterrupted operation in systems where downtime is costly, such as chemical batch processing or turbine control.

Flexible communication:
Dual serial ports (RS-232/RS-485) and a Genius bus interface support multiple protocols, enabling integration with HMIs (e.g., GE IC693HMI301), barcode scanners, and remote I/O racks. The Genius bus, operating at 1 Mbps, connects to distributed I/O modules like GE IC697MDL753, reducing wiring costs in large facilities such as steel mills.

Redundant operation:
When paired with a second GE IC697CPU781 and IC697RNR701 module, the CPU supports hot standby redundancy, with automatic failover (<100 ms) during hardware faults. This eliminates single points of failure, a must for industries like nuclear power, where unplanned downtime could lead to safety risks or significant financial losses.

Rugged industrial design:
A conformal coating protects against dust, moisture, and chemical vapors, while the module’s vibration resistance (10–2000 Hz, 10 G rms) ensures reliability in harsh environments—from foundries with high ambient temperatures to mining facilities with constant vibration. Its wide operating temperature range (0°C to +60°C) adapts to diverse climates, from temperate factories to desert power plants.

Seamless Series 90-70 integration:
The GE IC697CPU781 interfaces directly with Series 90-70 I/O modules (e.g., IC697ALG731 analog input, IC697MDL753 discrete output) via the rack backplane, enabling plug-and-play expansion. This compatibility simplifies system upgrades, allowing users to add modules without modifying existing wiring—a key advantage in retrofitting legacy systems.

Advanced diagnostics:
Front-panel LEDs (Power, Run, Fault, Redundancy Status) provide instant visual feedback, while built-in self-tests monitor CPU health, memory integrity, and bus communication. Faults are logged with timestamps, enabling technicians to trace issues like program errors or I/O module failures—reducing mean time to repair (MTTR) by up to 40% compared to older PLC models.

Installation and Maintenance
Pre-installation preparations: Before installing GE IC697CPU781, verify the IC697CHS791 rack is properly grounded to prevent electrostatic discharge (ESD). Use an ESD wrist strap during handling to protect sensitive components. Insert the CPU into the rack’s designated slot (typically slot 0), ensuring it seats firmly in the backplane. Connect external 24 VDC power to the rack via IC697PSD750, and attach communication cables to RS-232/RS-485 ports for HMI or peripheral connections. For redundant setups, install the second GE IC697CPU781 in slot 1 and connect the IC697RNR701 module to enable failover.
Maintenance suggestions: Perform monthly visual inspections of GE IC697CPU781 front-panel LEDs to confirm normal operation (green Run light, no Fault indicators). Clean dust from ventilation slots with compressed air quarterly to maintain cooling efficiency. Annually, back up the control program to external storage using Proficy PLC Programming Software, and update firmware to address compatibility issues with newer I/O modules. Test redundancy by powering down the primary CPU and verifying seamless switchover to the standby unit. Inspect backplane connections yearly for corrosion, especially in humid environments, to ensure reliable communication with I/O modules.
