ABB DFM01 | 37262-4-0369570 | Profibus DPV1 Fieldbus Communication Module

Product Overview

The DFM01 (37262-4-0369570) is a high-performance Profibus DPV1 communication module specifically engineered for the ABB Freelance 2000 Distributed Control System (DCS) and compatible ABB ACS drive families. It functions as a specialized gateway that facilitates bidirectional, high-speed data exchange between the system controllers and field-level devices. Supporting the DPV1 standard, the DFM01 allows for both cyclic data exchange and acyclic communication, which is essential for advanced device parameterization and detailed diagnostic monitoring in complex automation networks.
