ABB CM579-ETHCAT:AC500, Com. Module ETHERCAT

Why Choose the ABB 1SAP170902R0101 CM579-ETHCAT Communication Module?

The ABB 1SAP170902R0101, type designation CM579-ETHCAT, is an industrial EtherCAT master communication module designed for integration with the ABB AC500 programmable logic controller platform. It expands an AC500 automation system with high-speed EtherCAT communications, enabling the PLC to exchange process and control data with compatible EtherCAT slave devices.

The CM579-ETHCAT provides two RJ45 Industrial Ethernet interfaces with an integrated 2-port switch and supports 10/100 Mbit/s Ethernet communication. Full-duplex and half-duplex operation with auto-sensing helps simplify network integration, while a dedicated communication processor allows the module to handle EtherCAT communications independently of the main PLC processor.

Communication with the AC500 CPU is handled through 8 kB dual-port memory, and the module incorporates 256 kB Flash memory for its communication functions. Its compact 28 mm width makes the CM579-ETHCAT suitable for control cabinets where installation space is limited while providing powerful network connectivity for machinery, motion control and factory automation applications.
