GE Fanuc IC698CRE020

The IC698CRE020 is a high-performance 700 MHz Central Processing Unit designed for the GE Fanuc RX7i Series, utilizing an Intel Pentium III microprocessor. This CPU features Hot Standby Redundancy, ensuring that critical applications continue to function seamlessly in the event of a component failure. The Hot Standby configuration employs two CPUs: an active unit that actively manages the process and a backup unit that remains synchronized with the active unit, ready to take control when necessary. For effective redundancy functionality, the IC698CRE020 requires a Redundancy Memory Xchange module (RMX), specifically cataloged as IC698RMX016, which is typically configured as a redundancy link in each unit.

As with other RX7i CPUs, the IC698CRE020 operates with a software program tailored for executing specific tasks such as real-time process control, general machine operation management, and material handling applications. This CPU is equipped with 10 MB of battery-backed memory and 10 MB of non-volatile flash memory, providing access to bulk memory alongside user-configurable data and program memory. It supports Auto-located Symbolic Variables and is compatible with 90-70 Series discrete and analog I/O, along with Series 90-70 VME modules, ensuring extensive interoperability. For optimal operation stability, it is recommended to regularly replace the battery pack, which maintains essential functions such as the calendar clock, data memory, and program integrity during power outages.

Technical specifications include a processing speed of 700 MHz, 10 Mbytes of memory, support for floating-point operations, three serial ports, and compatibility with various serial protocols including Modbus RTU Slave, SNP, and Serial I/O. The embedded communication features consist of RS-232, RS-485, and an Ethernet interface.
