Description

Brief Product Description

The GE Fanuc IC697BEM713 is a high-speed bus transmitter designed for the Series 90-70 PLC, enabling seamless expansion of the local CPU bus to remote I/O racks. It supports a daisy-chain configuration for up to seven expansion racks, ensuring consistent data throughput across large-scale automation architectures.

Product Description

Local Bus Expansion and System Scalability

The GE Fanuc IC697BEM713 serves as the primary interface for extending the processing power of a Series 90-70 CPU to additional chassis. This Bus Transmitter module creates a bridge between the local CPU rack and peripheral I/O, allowing engineers to scale their control systems effectively. By utilizing this module, users can connect as many as seven IC697BEM711 Bus Receiver modules in a serial daisy-chain. This configuration maintains a high-speed data transfer rate of 500 Kbytes per second, which ensures that timing-critical I/O remains synchronized with the central processor.

Network Configuration and Requirements

To maintain signal integrity, the IC697BEM713 requires specific networking parameters during installation. The total cable distance from the transmitter to the final receiver in the chain must not exceed 50 feet (15 meters). Furthermore, the final receiver module in the network requires an IC697ACC702 terminating resistor to prevent signal reflection and communication errors. The module features two primary connection points: a parallel port for system programming and an expansion port dedicated to the first receiver link. Users can perform all configuration and software setup through standard Windows or MS-DOS programming environments.

Operational Status and Hardware Compatibility

The hardware design of the GE IC697BEM713 prioritizes diagnostic transparency and ease of use. Three integrated LEDs provide real-time feedback on the module’s health, indicating successful power-up, expansion bus activity, and active communication with the PLC programmer. While this module fits into any standard IC697 chassis slot, it cannot occupy Slot 1, as that position is reserved for the CPU. This transmitter is fully compatible with GE expansion cables ranging from 5 to 50 feet, providing flexibility for diverse cabinet layouts.
