Industrial Applications

The VE4022 Profibus DP Module is essentially the bridge between the DeltaV environment and specialized field equipment. In Water and Wastewater facilities, it is commonly utilized to control and monitor Intelligent Motor Control Centers (IMCCs) and high-power pumps. In Oil and Gas and Chemical Processing plants, this module facilitates the high-speed transfer of diagnostic and process data from complex valve manifolds and analytic instruments. By leveraging the acyclic communication features (DP-V1), engineers can remotely calibrate and troubleshoot field devices directly from the DeltaV engineering workstation, significantly reducing manual field inspections and improving overall plant reliability.
