The ABB CM‑DP B is a variant of the CM‑DP PROFIBUS‑DP communication module (internal part no. SAPR), compatible with ABB’s AC PLC line. This module supports PROFIBUS‑DP Master communication (DP‑V and V) at data rates up to  Mbit/s. The “B” suffix typically denotes a specific firmware or QC revision, while retaining identical functionalities and form factor to the standard unit. It integrates via a -pin D-sub connector, providing reliable fieldbus connectivity in compact PLC architectures.
