Deterministic Backplane & Processing Velocity
Engineers configure the GE Fanuc IC695CRU320 CPU to leverage dual-bus backplane architecture, combining high-speed PCI execution with serial backplane bus communication velocity for legacy Series 90-30 module migration. Operating at a clock frequency of 1.0 GHz, the Celeron processor coordinates real-time I/O density scaling while maintaining firmware flash compatibility across primary and secondary redundant racks. Dual-CPU synchronization via paired Memory Xchange modules preserves deterministic control and maintains active program execution during primary rack failover events.
Frequently Asked Questions
Q: How does the CPU maintain logic state and data retention during backplane power disruptions?
A: The module relies on an external IC695ACC302 Lithium Smart Battery or IC693ACC302 auxiliary battery pack to maintain the 64 MB volatile RAM contents when system backplane power drops.
Q: What is the maximum switchover latency provided by this redundancy CPU in a dual-rack configuration?
A: Switchover executes within a minimum of 3.133 ms and completes in no more than one logic scan cycle when coordinated via dedicated Memory Xchange hardware.
Field Installation Guidelines
Technicians must install the CPU into the designated central processing slot of the primary RX3i universal rack backplane. When establishing a hot-standby pair, both the primary and backup IC695CRU320 units must run identical firmware revisions to prevent synchronization failures. Serial RS-232 and RS-485 communication lines must use shielded twisted-pair conductors with ground drain wires terminated to frame ground at a single node to prevent ground loops. Always verify battery charge status prior to commissioning to guarantee non-volatile data preservation.
