Backplane Bus Communication Velocity & Redundancy Execution
The IC695CRU320-AA interfaces directly with the PACSystems RX3i PCI backplane bus, driving deterministic control execution and high-speed data synchronization. Backplane bus communication velocity and logic scan processing are optimized via dedicated redundancy transfer logic, maintaining bump-less switchover between primary and secondary controller racks. Firmware flash compatibility and revision synchronism ensure fail-safe memory mirror operations across synchronized backplanes without inducing control loop latency.
Frequently Asked Questions
Q: Can the IC695CRU320-AA CPU module be hot-swapped while the RX3i chassis is powered on?
A: No. Power to the rack chassis must be completely isolated prior to inserting or removing the main CPU module to prevent severe backplane PCI bus disruption and processor memory corruption.
Q: How is data synchronized between primary and backup IC695CRU320-AA processors in a redundant system?
A: Data synchronization is executed via high-speed fiber-optic Redundancy Bus Interface (RMX) modules linked between the active and hot-standby RX3i chassis.
Field Installation Guidelines
Ensure the main rack power supply is completely de-energized before mounting the IC695CRU320-AA into the designated CPU slot of the RX3i Universal Backplane. Secure the top and bottom module retaining screws to establish solid mechanical earth grounding through the metal chassis frame. RS-232 and RS-485 serial communications wiring must utilize shielded twisted-pair cables, with cable shields grounded at a single point to prevent ground loops and electromagnetic interference from disturbing high-speed processor execution.
