Function and Positioning

This module serves as a comprehensive communication expansion component for industrial control systems. It acts as a data bridge between the main controller and field devices via three independent communication ports. RS232 is used for connecting human-machine interfaces and serial peripherals, RS485/RS422 for long-distance serial network communication, and CAN bus for CANopen network devices. The isolation design effectively suppresses on-site electromagnetic interference. It reduces the communication load of the main CPU, improves system operation efficiency and networking flexibility, and is an essential part for building multi-protocol industrial control systems.
