ABB CM579-ETHCAT AC500 Communication Module

The ABB CM579-ETHCAT (Product ID: 1SAP170902R0101), also cataloged as the CM579-ETHCAT Communication Module, operates as a dedicated hardware component for EtherCAT master communication and fieldbus data routing within AC500 PLC platforms.

Hardware Specifications

Backplane Bus Communication Velocity & EtherCAT Determinism

The communication module relies on high-speed backplane bus communication velocity and firmware flash compatibility to exchange I/O process images with the primary AC500 CPU. Utilizing dual Industrial Ethernet ports operating at a data transmission rate of 100000 kbit/s, the module provides deterministic EtherCAT master control, enforcing real-time communication cycles and low jitter across connected field devices.

Frequently Asked Questions

Q: What physical installation footprint does the CM579-ETHCAT require within an AC500 CPU slot?

A: The module has physical dimensions of 28 mm in width, 135 mm in height, and 62 mm in depth, with a net weight of 0.101 kg.

Field Installation Guidelines

Disconnect system auxiliary power before attaching or removing the communication module from the AC500 CPU terminal base to avoid electrical contact arcing. Route all Industrial Ethernet cables in dedicated cable ducts away from high-voltage motor power leads to prevent electromagnetic noise coupling. Ensure Ethernet cable shielding is properly connected to earth ground, and maintain proper physical ventilation space around the IP20 chassis to facilitate thermal dissipation.
