📖 Operation Guidelines & Usage Instructions
The GE Fanuc IC697BEM733 is a Remote I/O Scanner (RIOS) module designed to manage high-speed communication between a Series 90-70 PLC rack and remote I/O drop locations across a Genius Bus network. Ensure all rack power and remote field power supplies are completely turned off before installing or removing the module. Align the unit carefully with the designated backplane slots and slide it smoothly into place before securing the front-panel retaining screws. Routine maintenance includes inspecting Genius bus cable shielding, checking terminating resistors, and verifying proper network address switch settings.
⚡ Power-Up / Power-Down Sequence
- Power-Up Sequence: Verify that the RIOS module is firmly seated into its assigned Series 90-70 rack slots and that the Genius Bus communication cables are securely attached to the front connector. Turn on the main rack power supply. Observe the front-panel diagnostic indicator LEDs (such as OK, CONFIG, and COMM) to confirm that the module completes its self-diagnostic boot cycle and establishes network communication.
- Power-Down Sequence: Place the PLC into program or stop mode via the programming software if necessary to halt active I/O polling. Turn off the main rack power supply distribution unit to cut all backplane voltage before extracting or servicing the module.
❓ Frequently Asked Questions (Q&A)
- Q: What is the primary function of the IC697BEM733 module in a Series 90-70 system?
A: It acts as a master scanner on the Genius I/O network, enabling the central PLC to cyclically read inputs from and write outputs to remote drop racks and field devices.
- Q: Can this Series 90-70 module be hot-swapped while the PLC rack is powered on?
A: No, Series 90-70 backplanes and modules do not support hot-swapping. Always power down the system entirely to prevent electrical damage to the module or backplane interface pins.
