The PROSOFT MVI56-PDPMV1 is a high-performance PROFIBUS DP-V1 Master communication module designed to enable ControlLogix processors to communicate efficiently with PROFIBUS DP-V0 and DP-V1 slave devices. Widely used in industrial automation applications requiring seamless protocol integration, this module allows engineers to unify diverse device networks under a single robust control architecture, simplifying system design and enhancing operational efficiency.
Industries such as manufacturing, chemical processing, pharmaceuticals, and logistics utilize the MVI56-PDPMV1 to bridge ControlLogix platforms with existing PROFIBUS infrastructures. It is applicable in control systems demanding real-time data transfer, advanced diagnostics, and acyclic parameter communications. The module addresses challenges associated with multi-vendor device interoperability and complex network topologies by supporting the full PROFIBUS Master specification per IEC 61158 standards. This capability enables communication with up to 125 PROFIBUS slave devices via reliable RS-485 physical layer, ensuring dependable data exchange for process control and monitoring.
As an integral component of Rockwell Automation’s modular I/O system, the PROSOFT MVI56-PDPMV1 fits into a single 1756 backplane slot, accessing processor memory for direct data transfers between PROFIBUS devices and the ControlLogix controller. It simplifies programming by using Ladder Logic for data exchange, with provided sample programs for rapid commissioning. Supporting user-configurable I/O backplane sizes, it optimizes performance for local or remote rack applications. CIPConnect™ enablement and compatibility with ProSoft Configuration Builder and FDT/DTM software facilitate device configuration and enhanced network diagnostics via Ethernet routing.
Built for reliability, the module withstands industrial vibrations, shock, and temperature ranges from 0°C to 60°C, with storage capabilities extending down to -40°C. Its front panel includes status LEDs for module operation, network communication, master token hold, and error indication, assisting quick troubleshooting. The device features isolated RJ45 and DB9M serial configuration ports for flexible setup.
