Product Description
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, and user-configurable data and program memory.
Auto-located Symbolic Variables are supported as are 90-70 Series
discrete and analog I/O. Series 90-70 VME modules are also
supported by this CPU. 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.
