Description
Product Name ：IC697BEM715RR GE Central control module
Product details:
The GE Fanuc IC697BEM715 (often designated with revision suffixes like RR) is a Bus Transmitter Module designed for the GE Fanuc Series 90-70 Programmable Logic Controller (PLC) system. It enables multi-rack expansion by transmitting signals from the main CPU rack to remote expansion racks.
Detailed Description
The IC697BEM715 module acts as an expansion interface within the Series 90-70 system architecture. When an application requires more I/O slots or specialized modules than a single rack can hold, this module is installed in the main rack. It converts internal parallel bus signals into a high-speed serial format to communicate with a corresponding Bus Receiver Module (such as the IC697BEM731) located in an expansion rack via a dedicated expansion cable.

Key Advantages
- Scalability: Allows system expansion up to 7 additional racks without changing the central CPU configuration.
- High-Speed Communication: Provides high-throughput parallel-to-serial conversion for minimal I/O updating latency.
- Plug-and-Play Integration: Seamlessly managed by the Series 90-70 CPU backplane with minimal software configuration required.
- Industrial Reliability: Built to harsh industrial automation standards, providing stable operation in high-noise electrical environments.
Important Precautions & Installation Notes
- Power Down Before Installation: Never insert or remove the IC697BEM715 module while the rack power supply is energized to prevent hardware damage or unexpected CPU halts.
- Cable Termination: Ensure proper bus termination on the last expansion rack in the chain to avoid signal reflection and communication errors.
- Cable Distance Limits: Do not exceed the maximum specified cable length (15 meters / 50 feet total) to ensure noise immunity and timing accuracy.
- Grounding: Proper grounding of expansion cables and racks is mandatory to prevent ground loops and electromagnetic interference (EMI).
Typical Applications
- Large-Scale Industrial Automation: Processing plants or factory floors requiring hundreds of discrete and analog I/O points across multiple racks.
- Power Generation & Utilities: Supervisory and sequence control systems where local and remote racks control distributed turbines or valves.
- Water Treatment & Chemical Facilities: Distributing I/O chassis across larger physical areas while retaining central CPU execution.
