High-Speed Backplane Bus & Deterministic Determinism
The IC695CRU320 executes high-density data synchronization across dual backplane bus interfaces, leveraging electrical compliance with the PCI 2.2 architecture. This dual-bus design enables high-throughput memory transfers without degrading local I/O execution or cycle timings. Internal Error Checking and Correction (ECC) logic actively monitors the 64 MB memory array, performing single-bit correction and multi-bit detection to prevent execution halts caused by soft memory corruption. By utilizing high-speed synchronization links, the processor dynamically mirrors up to 2 MB of data in the transfer list, guaranteeing seamless failover execution during system hardware faults.
Frequently Asked Questions
Q: What is the maximum redundancy switchover time for the IC695CRU320 during a primary unit fault?
A: The hardware guarantees a deterministic switchover execution time with a minimum latency of 3.133 msec and a maximum bound of 1 logic scan, preserving process continuity.
Q: How is memory retention preserved on the IC695CRU320 module during main power interruption?
A: Volatile RAM retention is maintained using an external lithium battery module (IC695ACC302 or IC693ACC302). Additionally, non-volatile Flash memory rated for 100,000 write/erase cycles protects application logic against permanent power loss.
Field Installation Guidelines
Ensure complete power removal from the PACSystems RX3i base rack prior to inserting or removing the IC695CRU320 module. Confirm that the module guide rails align precisely with the targeted backplane slot, pressing firmly until the top and bottom retention levers snap securely into place. Maintain effective single-point grounding across the DIN-rail or panel enclosure frame to divert high-frequency transients away from the serial communications ground plane. When setting up RS-232 or RS-485 networks via the embedded serial ports, run shielded twisted-pair cabling isolated from high-voltage AC lines, grounding the cable shield at one end only to prevent ground loops.
