ABB CM574-RS Communication Module

Description

The ABB CM574-RS Communication Module is a serial communication module designed for industrial automation systems. As a configurable protocol unit, it features 2 independent COM ports that support both RS232 and RS485 communication protocols, enabling dedicated CS31 bus or Modbus RTU IO communication management. Equipped with its own independent user program, the module can meet complex application requirements without the need for an additional high-performance CPU, effectively reducing system response time to optimize operational efficiency. Key physical and functional specifications include a three-phase power supply and a white housing. This module integrates seamlessly into industrial setups, providing reliable, flexible communication control for applications that demand streamlined data transmission and simplified system architecture, eliminating the need for overprovisioned central processing hardware to achieve robust, responsive IO communication management.
