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.

Acyclic Data Support: Unlike standard DPV0 modules, the DFM01 (37262-4-0369570) supports DPV1 acyclic services, allowing engineers to perform remote calibration and asset management without interrupting the primary control cycle.
-
Plug-and-Play Integration: Specifically tailored for the Freelance 2000 environment, the module is automatically recognized by the system configuration software, simplifying GSD file management.
-
Deterministic Communication: High-speed processing ensures minimal jitter and latency, which is critical for synchronized drive control and process safety loops.
-
Ruggedized Connectivity: Features reinforced Profibus DB9 ports designed to withstand the mechanical stresses of industrial vibration and frequent connection cycles.
What's clients say about us
Excellent Emergency Support!
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
