Backplane Bus Communication Velocity and Firmware Compatibility
The module resides in a single slot of the RX3i rack and communicates across the high-speed RX3i backplane bus to execute real-time synchronization between the CPU and external Genius nodes. Integrated firmware flash components handle serial transmission framing at 153.6 Kbps, managing up to 128 bytes of inbound and outbound global data packets per scanning cycle without introducing cycle-time jitter. The hardware architecture supports redundant bus topology setups, automatically maintaining backplane data coherence during network path failover events.
Frequently Asked Questions
Q: How many IC694BEM331A modules can reside in a single PACSystems RX3i rack configuration?
A: A single PACSystems RX3i controller system accommodates up to 8 IC694BEM331A modules, allowing expansion across multiple distributed Genius I/O sub-networks.
Q: Can the IC694BEM331A module be removed or inserted while the RX3i backplane is powered?
A: No, system power must be completely turned off before installing or extracting the module from the RX3i backplane slot to prevent electrical shock or hardware damage.
Q: What remote devices connect to the RX3i backplane through this module?
A: The module interfaces directly with Genius I/O blocks, VersaMax drops, compatible HMIs, and secondary PLCs configured with Genius Bus Controllers.
Field Installation Guidelines
Turn off all rack power supplies before inserting the IC694BEM331A module into the designated RX3i rack slot. Press the module firmly into place until the rear backplane connector fully seats and locks into the baseboard receptacle. Route the Genius bus shielded twisted-pair cabling through dedicated wire ducts, maintaining adequate separation from AC power lines and variable frequency drive output wiring. Connect the cable shield drain wire directly to the cabinet signal ground bus bar to suppress ambient electromagnetic interference and ensure proper network noise immunity.
