GE Fanuc IC697BEM733D Series 90-70 Remote I/O Scanner
The GE Fanuc IC697BEM733D, also cataloged as the IC697BEM733 Genius Remote I/O Scanner Module, operates as a dedicated hardware component for remote I/O rack scanning and signal interchange within GE Fanuc Series 90-70 PLC Genius bus networks. The module occupies a single rack slot, managing up to 1024 discrete I/O points or 64 analog I/O words over a daisy-chained serial line to execute real-time control updates.

Backplane Bus Performance & I/O Density Scaling
The module manages deterministic serial communication over the Genius bus interface, maintaining synchronization between the host CPU backplane and remote extension racks. System architectures leverage I/O density scaling by supporting up to 32 drop stations per bus network at defined baud rates, driving arrays of discrete and analog expansion blocks. Internal bus driver circuitry maintains firmware flash compatibility with Series 90-70 CPU backplanes, transferring serial frame data without interrupting parallel backplane bus processing.
Frequently Asked Questions
Q: What line termination resistance values are required at the physical ends of the serial bus?
A: Install a 75, 100, 120, or 150 ohm terminating resistor across the bus terminals at both physical ends of the cable run to match the characteristic impedance of the selected Twinax or shielded twisted-pair line.
Q: What is the peak current demand of the module on the backplane power supply?
A: The module draws a nominal current of 0.8 A from the 5.0 VDC backplane bus during standard operation, reaching a maximum power load of 1.3 A under full serial bus drive conditions.
Field Installation Guidelines
Insert the module into a single rack slot of a Series 90-70 rack while the backplane power supply is switched off. Tighten the top and bottom retaining screws to establish electrical ground continuity with the chassis. Wire the Genius serial bus in a daisy-chain layout using shielded twisted pair or Twinax cable. Install terminating resistors (75, 100, 120, or 150 ohms) across the terminal connections at both physical ends of the bus line. Separate serial communications wiring from high-voltage AC conductors and attach the cable shield to a single protective earth panel ground.
