GE Fanuc IC697BEM733H Series 90-70 Genius I/O Scanner Module
Configured for remote I/O link management and field bus coordination in Series 90-70 systems, the GE Fanuc IC697BEM733H (IC697BEM733 Distributed I/O Scanner Module) provides direct physical/electrical execution. The module acts as an intelligent controller interfacing Series 90-70 backplanes to Genius (IC66*) remote I/O devices, executing real-time data transfers across up to 32 drops per bus segment. Supporting discrete I/O, analog I/O, PCM, and ADS units, the scanner maintains deterministic transmission rates up to 153.6 Kbaud with 128 input bytes and 128 output bytes transferred per drop cycle.

Backplane Bus Communication & Deterministic Network Execution
The module manages high-speed backplane bus communication cycles, exchanging remote I/O data tables directly with the main Series 90-70 CPU without introducing scan delay overhead. Internal flash firmware compatibility provides transparent address routing for mixed discrete, analog, and complex function cards attached to remote Genius blocks. Operating on deterministic token-passing networks, the hardware regulates frame timing and channel arbitration across daisy-chained shielded twisted-pair or Twinax media, maintaining data throughput across extended cable runs up to 7500 ft.
Frequently Asked Questions
Q: How does the IC697BEM733H module handle bus line termination across different baud rates?
A: Physical bus ends require proper resistor termination (selectable between 75, 100, 120, or 150 ohms) matching cable characteristic impedance to suppress signal reflections and maintain wave integrity at higher baud rates.
Q: Can configuration and diagnostic routines be executed without disturbing active PLC scan cycles?
A: Yes, connecting an IC66* handheld monitor to the front-panel 9-pin port allows online diagnostic sweeps, device parameter adjustments, and force-bit checks without interrupting real-time backplane data execution.
Field Installation Guidelines
Turn off main rack power before inserting the module into its assigned slot on the Series 90-70 backplane. Seat the module firmly along card guide rails until top and bottom latches click tightly, establishing chassis earth bonding. Route Genius bus connections using approved shielded twisted pair or Twinax cabling, maintaining a daisy-chain topology with impedance-matched terminating resistors installed at both physical line endpoints. Separate communication cable conduits from high-voltage AC power wiring inside panel gutters by a minimum of 200 mm. Verify proper ground shield continuity, grounding the shield drain wire at one point only to avoid ground loop noise currents. Ensure enclosure convection pathways maintain ambient temperatures between 0 deg C and +60 deg C under non-condensing humidity levels up to 95%.
