Backplane Bus & Deterministic Networks
The module communicates with the CPU via high-speed VMEbus dual-port RAM, allowing real-time memory mapping without slowing down controller sweep times. Backplane bus communication velocity and firmware flash compatibility ensure deterministic data exchange across the network. The hardware manages global data transfers and diagnostic reporting, maintaining stable communication and high I/O density scaling across distributed Genius racks.
Frequently Asked Questions
Q: Can the IC697BEM731U module be replaced while the VME backplane is under power?
A: No, the module is not hot-swappable. Always turn off power to the rack prior to installing or removing the module to avoid hardware damage or memory corruption.
Q: How is the module configured if no Hand-Held Monitor is connected?
A: The board receives its operational parameters, including serial address and baud rate assignments, directly from the CPU configuration generated via Proficy Machine Edition or Logicmaster 90 software.
Field Installation Guidelines
Insert the IC697BEM731U into a single slot of the Series 90-70 rack with system power switched off. Fasten the board retention screws securely to maintain continuous chassis shield grounding. Route Belden 9182 shielded twinaxial cable directly to the front terminal connections, maintaining a total line length within specified limits based on the configured baud rate (up to 7,500 ft at 38.4 kbps). Install matching 75 Ohm or 150 Ohm bus termination resistors across the serial line terminals at both physical ends of the network to prevent signal reflections.
