Product Overview

The IC697BEM713G is a Bus Expansion Transmitter (BXT) module for the GE Fanuc Series 90-70 PLC system. It provides a high-speed hardware link that extends the CPU backplane across multiple racks, allowing remote or expansion I/O racks to operate as part of a unified control system.

This design enables distributed I/O architectures while maintaining local backplane performance across all connected racks.

Technical Specifications

Engineering Advantages

Zero-Latency Data Distribution
Direct backplane mirroring eliminates network delays, enabling expansion racks to perform with the same timing precision as the main CPU rack.

Simplified Multi-Rack Architecture
Supports scalable daisy-chained rack configurations, allowing engineers to expand I/O capacity without redesigning control logic or software structure.

High-Integrity Signal Transmission
Differential signaling and shielding reduce EMI impact, ensuring stable communication in electrically noisy industrial environments.

Unified Programming Model
All expansion I/O appears as local to the CPU, eliminating the need for additional communication mapping or network configuration.

FAQs

Is this module brand new?
Yes, the IC697BEM713G is supplied as a 100% brand new original unit in factory-sealed condition.

What cable is required?
It uses the IC697CBL series expansion cable designed specifically for high-speed backplane extension.

Do I need a receiver module?
Yes, it must be paired with an IC697BEM711 receiver module in the remote rack.

Can it be hot-swapped?
No. Power must be removed from both racks before connecting or disconnecting the expansion bus to avoid system damage or data corruption.
