GE IC698CRE030

Description

Product Description

GE IC698CRE030 is a high-performance, rack-mounted Controller (CPU) module for the GE Fanuc Series 90-70 PLC system, which is part of the later RX7i product family. This module, the IC698CRE030, serves as the central processing unit and the primary logic solver for the automation system. It executes the user-programmed control logic, manages communications with local and remote I/O, and coordinates data exchange with other controllers and supervisory systems. The core function of the GE IC698CRE030 is to provide deterministic control for complex, high-speed, and high-I/O-count applications. It is designed for demanding tasks in industries like power generation, metals, and transportation. The processing power and memory capacity of the IC698CRE030 make it suitable for coordinating multiple processes and handling extensive program data. For system architects requiring robust control within the GE ecosystem, the GE IC698CRE030 represents a capable and scalable controller solution.

Selection Suggestions and Precautions

1. Legacy System Consideration: The Series 90-70/RX7i platform, including the GE IC698CRE030, is a discontinued product line. Selection should be primarily for spare part replacement in existing systems, not for new greenfield projects.
2. Firmware Version Compatibility: The CPU’s firmware version must be compatible with the programming software version (Proficy ME) and the firmware of all connected I/O and communication modules in the rack.
3. Chassis and Backplane Compatibility: The controller must be installed in a compatible IC698 chassis (e.g., IC698CHSxxx). Verify the chassis model and backplane configuration.
4. Memory Backup: Always have a verified, recent backup of the controller’s program and configuration before performing any maintenance or replacement. The program is stored in volatile RAM backed by a battery; loss of power without a backup results in complete program loss.
5. Battery Maintenance: The IC698CRE030 uses a lithium battery to retain the program and real-time clock during power outages. Check and replace this battery periodically according to manufacturer guidelines to prevent unexpected memory loss.
6. Sourcing from Specialists: Given its status as a critical legacy component, source the GE IC698CRE030 from suppliers who specialize in GE PLC systems and can provide testing assurance and compatibility guarantees.
