ProSoft MVI56-PDPMV1 PROFIBUS DPV1 Master Communication Module
MVI56-PDPMV1 is a licensed PROFIBUS DPV1 master communication module developed by ProSoft Technology for Rockwell 1756 ControlLogix PLC racks. Compliant with IEC 61158 standard, it acts as a protocol gateway, realizing bidirectional data exchange between ControlLogix backplane and PROFIBUS DP V0/V1 slave devices including inverters, sensors and remote I/O stations. It supports cyclic process data transmission and acyclic DPV1 parameter read/write, covering real-time control and equipment parameter calibration demands simultaneously.
This single-slot rack module is recognized as a standard I/O module by Logix controllers, compatible with both local and remote ControlLogix chassis. It equips RS232 configuration port and PROFIBUS DP DB9 interface, with built-in multi-status LED indicators for real-time fault diagnosis. Supported by ProSoft Configuration Builder software for GSD file import, network topology editing and online slave monitoring, it serves as a core aftermarket spare for retrofitting and maintenance of hybrid Rockwell-PROFIBUS automation systems.

Core Functions
- Scan full PROFIBUS DP network cyclically, transmit real-time production data between ControlLogix CPU and field slave equipment via rack backplane.
- DPV1 Class1/Class2 acyclic service support: read/write slave parameters, calibration data and extended diagnostic information without interrupting cyclic control.
- Built-in Sync/Freeze synchronization commands for multi-axis motion control, ensuring synchronous sampling and output of multiple drive units on the bus.
- Online real-time fault diagnosis captures slave offline, bus short-circuit and communication timeout alarms, uploading detailed fault codes to Logix controller for troubleshooting.
- CIPConnect routing allows remote configuration via ControlLogix Ethernet modules, supporting offline project backup and batch parameter modification through PC software.
- Standard 1756 rack unified pin definition enables direct ｄｒｏｐ-in replacement, no chassis wiring modification required during on-site equipment overhaul.
Application Scenarios
