Rockwell Automation Prosoft ControlLogix MVI56-DNP

DNP 3.0 Master/Slave Network Interface Module for ControlLogix - MVI56-DNP

The MVI56-DNP module serves as a bridge between ControlLogix processors and a wide array of field devices that support the DNP (Distributed Network Protocol) communication standard. DNP is an open, non-proprietary protocol widely adopted in the electric utility, oil & gas, and water/wastewater industries to ensure interoperability among systems. It is designed to optimize data acquisition and control command transmission, offering high efficiency and reliability in communications between substation computers, RTUs, IEDs, and master stations.

The MVI56-DNP module leverages DNP's layered protocol architecture, including time-stamping and True Report by Exception (TRBE) features, to provide real-time data transmission to the processor without the need for polling. This ensures critical data is delivered promptly in emergency situations.
