Backplane Bus & Deterministic Networks
The module links directly to the Series 90-70 CPU across high-speed VMEbus backplane architecture via dual-port RAM. High backplane bus communication velocity allows simultaneous token-passing control across both independent channels without causing sweep latency. Proper firmware flash compatibility enables real-time diagnostic collection, global data register synchronization, and fault-tolerant redundant network operations across distributed Genius I/O blocks, BIUs, and DCMs.
Frequently Asked Questions
Q: Can the IC697BEM713G module be removed or replaced while the main rack is under power?
A: No, the module is not hot-swappable. System operators must de-energize backplane power before inserting or extracting the board to prevent logic corruption or hardware damage.
Q: How does the dual-port configuration affect the device capacity per Series 90-70 slot?
A: Each port manages an independent Genius bus containing up to 31 devices (addresses 0 through 31), allowing a single slot module to interface up to 62 field devices total.
Field Installation Guidelines
Seat the IC697BEM713G firmly into a standard Series 90-70 single slot with backplane power fully disconnected. Secure top and bottom panel screws to ensure solid electrical ground continuity with the rack chassis. Route shielded twinaxial cables (RG-58/U or equivalent) to the designated front connectors for Bus 1 and Bus 2, keeping signal paths away from heavy power conduits. Connect 75 Ohm or 150 Ohm termination resistors across the serial terminals at both physical ends of each daisy-chain link to suppress signal reflection and maintain 1500 VAC galvanic isolation.
