ABB CM579-ETHCAT 1SAP170902R0001 Communication Module

Product Introduction

The ABB CM579-ETHCAT (Order Code: 1SAP170902R0001) is a high-performance EtherCAT communication module designed to integrate seamlessly with ABB’s AC500 PLC family. This module functions as an EtherCAT Master, enabling ultra-fast, deterministic, and synchronized communication between the AC500 central processing unit and a wide array of EtherCAT-enabled slave devices such as I/O systems, drives, sensors, actuators, and motion control components.

EtherCAT (Ethernet for Control Automation Technology) is a real-time Ethernet fieldbus technology well-regarded for its speed, low latency, and precise synchronization. The CM579-ETHCAT leverages these capabilities, making it ideal for applications that require real-time control and tight coordination of distributed devices.

Built for industrial-grade environments, this module delivers not just performance, but also reliability, flexibility, and scalability—essential characteristics for modern automation systems across industries like manufacturing, robotics, packaging, and process control.
