ABB – CM578-CN B2 – CANopen Master Communication Module (1SAP170800R0001)

The ABB CM‑CN B (part number SAPR) is a CANopen master communication module designed for use with ABB’s AC and S 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 -pole spring terminal connector and supports data transmission rates up to  Mbit/s. The B suffix denotes a firmware or QC revision, with identical hardware and functionality as other CM‑CN variants.
