ABB – CM578‑CN B2 – CANopen Master Communication Module (1SAP170800R0001)
The ABB CM578‑CN B2 (part number 1SAP170800R0001) is a CANopen master communication module designed for use with ABB’s AC500 and S500 programmable logic controllers. It allows connection of the PLC to a CANopen network as the master, facilitating control over various field devices such as sensors, drives, and distributed I/O. The module communicates via a 5-pole spring terminal connector and supports data transmission rates up to 1 Mbit/s. The B2 suffix denotes a firmware or QC revision, with identical hardware and functionality as other CM578‑CN variants.
