ProSoft MVI56‑PDPS PROFIBUS‑DP Slave Communication Module

ProSoft MVI56‑PDPS is a PROFIBUS‑DP slave communication module for Rockwell ControlLogix 1756 chassis. It acts as protocol conversion gateway, enabling ControlLogix PLC to operate as PROFIBUS‑DP slave node and realize bidirectional data exchange with external PROFIBUS‑DP master stations.

This single‑slot module supports DP‑V0 and DP‑V1 acyclic communication services, equipped with DP bus connector and configuration debugging serial port. It is configured via ProSoft ConfigurationBuilder software, widely used as replacement spare parts for manufacturing, petrochemical and power industry cabinet transformation and maintenance projects.
