The ABB CM579-ETHCAT is a dedicated EtherCAT master communication module designed for the AC500 platform, delivering high-speed, deterministic connectivity for demanding motion and real-time control applications. As part of the CM579 series, this module integrates seamlessly with ABB’s distributed automation PLCs, enabling precise synchronization of drives, I/O, and other EtherCAT slaves. With a data transmission rate of 100,000 kbit/s and two Industrial Ethernet ports, the CM579-ETHCAT ensures robust network performance and flexibility. Its compact form factor—135 mm high, 28 mm wide, and 62 mm deep—combined with a net weight of just 0.101 kg, allows for easy installation in tight control panels. The module is rated IP20 for basic protection in industrial environments and supports serial communication interfaces. Whether used in standalone configurations or as part of a controller kit (e.g., with PM5630-2ETH or PM5650-2ETH), the CM579-ETHCAT provides reliable, low-latency EtherCAT master functionality essential for advanced automation tasks.
