وصف التقييمات

The General Electric IC697BEM711 is a high-speed parallel bus expansion interface module designed for the Series 90-70 Programmable Logic Controller (PLC) architecture. This module facilitates the expansion of the PLC system by allowing the connection of up to seven additional expansion racks to the main CPU baseplate. It provides a robust communication link with an effective data transfer rate of 500 Kbytes/sec, ensuring high-performance coordination across distributed I/O points.

Features

High-speed parallel bus expansion interface for Series 90-70 systems.
Supports daisy-chaining up to seven expansion racks.
Includes Hold Last State functionality to maintain output values during communication loss.
Optical isolation between logic and field circuits for enhanced noise immunity.
Integrated status monitoring via three front-panel LED indicators (Module OK, Last Rack, Bus Active).
Simplified configuration through software without the need for manual DIP switch settings.

Applications

Automotive Manufacturing: Facilitates coordinated control across extensive assembly lines and paint shop I/O.
Process Automation: Supports complex distributed control in oil, gas, and chemical processing facilities.
Water Treatment: Enables reliable remote I/O communication for expansive municipal infrastructure.
High-Volume Manufacturing: Provides the throughput required for rapid machine action and process synchronization.

Installation Guidelines

Ensure the PLC rack power is disconnected before installing or removing the module.
The module must be installed in Slot 1 of the expansion rack.
Use the appropriate interconnecting cables for daisy-chaining; total system cable length must not exceed 50 feet (15 meters).
An I/O Bus Terminator Plug (IC697ACC702) is mandatory on the final rack in the expansion chain to ensure signal integrity.
Maintain proper grounding practices and keep communication cables routed away from high-voltage power lines to minimize EMI interference.

FAQs

What is the primary function of the IC697BEM711?

The IC697BEM711 acts as a bus expansion interface for the GE Series 90-70 PLC, allowing the system to scale by adding up to seven additional I/O racks.

What happens if communication is lost between the CPU and the expansion rack?

The module supports a "Hold Last State" feature, which ensures that connected output modules maintain their current operational state rather than defaulting to an unmonitored or unsafe condition.

Are there specific requirements for the last rack in the chain?

Yes, the last rack in your expansion daisy chain must be fitted with an I/O Bus Terminator Plug (IC697ACC702) for the system to function correctly.

How are the ports configured on this module?

The module features two 25-pin D-shell connectors: one port is used to receive data from the upstream CPU rack, and the second port is used to daisy-chain to the subsequent expansion rack.
