Function and Positioning

This module is the core expansion unit of the X2X + CAN + RS485/RS422 three-protocol communication of SYSTEM 2005 PLC. It integrates X2X Link master station, CAN bus, and RS485/RS422 interfaces, achieving high-speed I/O links, fieldbus networking, and long-distance serial communication. X2X Link is the master station interface, electrically isolated, high-speed transmission, used to connect X20 series remote I/O modules, building a distributed control system, supporting long-distance expansion and real-time data interaction. CAN bus interface is electrically isolated, supports CAN 2.0A/B and CANopen master/slave stations, up to 500kbps, connecting CANopen servo, frequency converter, remote I/O, and field instruments, achieving fieldbus control. RS485/RS422 interface can be configured, supports point-to-point or multi-point communication, up to 115.2kbps, maximum transmission distance 1200 meters, suitable for serial sensor, upper computer, and third-party equipment networking. Electrical isolation between interfaces and between interfaces and system bus is strong; supports hot swapping, maintenance without downtime; completed X2X link, CAN parameters, and serial configuration through Automation Studio, suitable for distributed I/O architecture, CANopen device networking, long-distance serial communication, and multi-system integration scenarios.
