Product Overview

The GE Fanuc IC697BEM711N serves as the high-speed communication anchor for distributed Series 90-70 PLC architectures. This Bus Expansion Module (BEM) functions as a Bus Receiver, physically extending the CPU's parallel backplane to additional I/O racks. By utilizing two 25-pin D-shell connectors, the module creates a high-integrity data link that supports up to seven expansion racks per system. The IC697BEM711N ensures that the CPU maintains synchronous control over remote I/O modules with an effective data rate of 500 Kbytes/sec, making it an essential component for large-scale industrial applications requiring high-density I/O concentration across multiple enclosures.

Engineering Advantages

High-Speed Parallel Extension: The IC697BEM711N replicates the CPU backplane performance across remote distances. The 500 Kbytes/sec data rate eliminates the communication bottlenecks typical of serial remote I/O, ensuring that remote digital and analog signals update at near-local speeds.
Simplified Rack Addressing: Integrated jumper settings allow engineers to define unique rack addresses directly on the module. This hardware-based addressing ensures that the CPU correctly identifies and maps I/O points across the multi-rack topology without complex software overhead.
Daisy-Chain Topology Support: Dual D-shell ports facilitate a convenient "in-and-out" wiring configuration. Port 1 receives the expansion bus from the direction of the CPU, while Port 2 passes the bus signals to the next rack in the sequence, streamlining cable management in large control cabinets.
Real-Time Diagnostic Feedback: Three dedicated LEDs provide instant troubleshooting data. The "Module OK" LED confirms internal health, "Bus Active" validates data traffic, and the "Last Rack" LED confirms the end-of-line termination status, significantly reducing commissioning time.
Non-Isolated Differential Signaling: The module employs differential communication to provide robust noise immunity across the 50-foot maximum cable span, protecting data integrity in environments with high electromagnetic interference (EMI).

FAQs

Where must I install the IC697BEM711N in the expansion rack?You must install the Bus Expansion Module in Slot 1 of every Series 90-70 expansion baseplate. This slot provides the necessary interface logic to bridge the expansion cable with the local backplane.
Does this module require a terminator?Yes. To maintain signal integrity and prevent data reflections, you must plug an IC697ACC702 Terminator into the unused Port 2 of the final expansion rack in the daisy chain.
What is the maximum distance supported by the IC697BEM711N?The system supports a maximum total cable length of 50 feet (15 meters). Exceeding this distance can degrade the parallel bus signals and cause communication faults.
Is this product "Brand New"?We guarantee that this IC697BEM711N is 100% Brand New and Original GE Fanuc/Emerson equipment. Every unit ships in its original factory-sealed packing with a full 12-month technical warranty.
