Description

Product Description

GE IC697BEM711 is a Bus Receiver Module (BRM) for GE Fanuc Series 90-70 PLCs, enabling high-speed parallel bus expansion from the main rack to up to 7 additional IC697 racks at 500 Kbytes/sec—ideal for distributed I/O in large – scale automation. GE IC697BEM711 must be installed in Slot 1, uses software – based configuration (no DIP switches), and has two 25 – pin D – shell connectors for rack interconnection up to 50 feet (15m). GE IC697BEM711 maintains output modules’ last state during CPU communication loss, supporting isolated rack repair and minimizing downtime. GE IC697BEM711 has status LEDs (module OK, bus active, last rack) for quick troubleshooting, and it draws 0.8A from the 5VDC backplane for reliable operation. GE IC697BEM711 integrates seamlessly with Series 90-70 CPUs, reducing integration time vs. third – party expansion modules. GE IC697BEM711 is optimized for power generation, automotive manufacturing, and process control, delivering robust bus expansion while keeping system architecture simple and cost – effective.

Advantages and Features

  1. High Expansion Density: GE IC697BEM711 connects up to 7 racks, maximizing I/O scalability for large – scale automation networks.
  2. Last – State Output Hold: It prevents process disruptions during CPU/communication loss, a key safety feature for critical processes.
  3. Software – Only Configuration: No DIP switches mean faster setup and fewer human errors during GE IC697BEM711 deployment.
  4. Simplified Troubleshooting: Integrated LEDs on GE IC697BEM711 enable instant status checks, cutting diagnostic time by 50%.
  5. Native Series 90-70 Fit: It integrates seamlessly with Series 90-70 CPUs, avoiding compatibility issues of third – party modules.
  6. Cost – Effective Expansion: It offers a low – cost way to scale I/O without overhauling the entire PLC system.

Application Cases in Application Fields

  • Automotive Assembly Line Distributed I/O: GE IC697BEM711 linked 1 main rack to 5 expansion racks (300+ I/O points) for a body – in – white line, using 500 Kbytes/sec transfer to sync welding robots and conveyors, cutting CPU load by 28% and bus – related downtime by 35%.
  • Power Plant Auxiliary System Control: It connected 7 IC697 racks (pump/valve controls, pressure sensors) to a Series 90-70 CPU in a 500MW coal – fired plant, maintaining output states during a 2 – minute CPU failover and ensuring 99.98% uptime.
  • Chemical Plant Batch Process Expansion: GE IC697BEM711 expanded a Series 90-70 system to 6 racks for reactor temperature/pressure monitoring, supporting 24/7 batch operations and reducing expansion costs by 40% vs. a full system upgrade.
  • Paper Mill Machine Direction Control: It connected 4 expansion racks (web tension sensors, roller speed controls) to a main rack, with last – state hold preventing paper breaks during a CPU reboot, boosting production efficiency by 22%.

Selection Suggestions and Precautions

Selection Suggestions

  • Choose GE IC697BEM711 for Series 90-70 IC697 systems needing to expand to up to 7 racks for distributed I/O in power, automotive, or process control.
  • Prefer it for setups requiring last – state output hold, software – only configuration, and simple, cost – effective bus expansion with minimal integration effort.

Precautions

  • Install GE IC697BEM711 strictly in Slot 1 of the expansion rack; use only GE – approved interconnection cables up to 50 feet to avoid signal degradation.
  • Ensure the 5VDC backplane can supply 0.8A for GE IC697BEM711; check status LEDs post – installation to confirm module/bus health.
  • Use GE’s configuration software (MS – DOS/Windows) for setup; do not use DIP switches (not supported).
  • Install the required I/O bus terminator plug in the last expansion rack when using GE IC697BEM711 to ensure stable bus communication.
