Backplane Bus Interface and Channel Scaling
The IC697BME731 interacts with the host Series 90-70 CPU across a VMEbus architecture, exploiting deterministic backplane bus communication velocity to manage global data exchange and distributed I/O scan routines. High I/O density scaling allows a single controller channel to coordinate data frames across 30 downstream Genius devices without loading local processing tasks. Internal firmware flash compatibility ensures synchronized network timing and seamless fault reporting across legacy Logicmaster 90 and Proficy Machine Edition programming tools.
Frequently Asked Questions
Q: Can the IC697BME731 module be inserted into or removed from the VMEbus rack while system power is active?
A: No, live insertion is not supported. The host rack must undergo a complete power shutdown prior to module extraction or seating to avoid backplane bus faults or hardware damage.
Q: How are network termination parameters selected on the physical Genius Bus line?
A: Network termination requires user-installed resistors (75 Ohm or 150 Ohm) placed across the physical twinaxial cable terminals at both ultimate ends of the bus to match cable impedance and mitigate signal reflections.
Field Installation Guidelines
Ensure the main power supply to the Series 90-70 baseplate is isolated before sliding the IC697BME731 into its single-slot housing. Align the module circuit board with the upper and lower card guides in the rack, pushing firmly until the VMEbus backplane connectors seat completely. Secure the top and bottom retaining screws to ensure proper frame grounding. Route the Belden 9182 shielded twinaxial cable away from high-voltage AC conductors, ensuring the cable shield is grounded at a single earth point to eliminate ground loops. Connect a Hand-Held Monitor to the front port if local address assignment or field verification is required.
