IC698CRE020 for the Rx7i is a high availability 700MHz CPU weighs 1.524 lbs.

The IC698CRE020 is a 700 MHz Central Processing Unit with an Intel Pentium III microprocessor manufactured by GE Fanuc for the RX7i Series. This CPU is equipped with Hot Standby Redundancy to allow critical applications to continue operating in case of failure in any single component.

A Hot Standby system uses two CPUs. One CPU is the active unit that aggressively controls the process, and the other is a backup unit that is synchronized with the active unit and can take over the process when necessary. To accomplish redundancy, the IC698CRE020 requires a Redundancy Memory Xchange module (RMX) catalogued as IC698RMX016. It is normally configured as a redundancy link in each unit.

The IC698CRE020, like any other RX7i CPU, is installed with a software program configured to initiate and complete specific tasks. Such tasks include controlling the device in real time mode, maintaining general machine processes, and handling materials applications.

Additional features of the IC698CRE020 include:

• 10MBs each of battery-backed memory and non-volatile flash memory
• Access to bulk memory
• User-configurable data and program memory
• Auto-located Symbolic Variables support
• 90-70 Series discrete and analog I/O support
• Series 90-70 VME modules support

To avoid the possibility of losing the CPU's RAM, it is advisable to maintain a routine procedure that involves replacement of the battery pack in due time. The battery is responsible for the overall stability of operations like the calendar clock, data memory, and programs during the absence of power.
