PROSOFT MVI56-PDPMV1
Product introduction
The ProSoft MVI56-PDPMV1 is a versatile PROFIBUS DP Master/V Slave communication module designed for Allen-Bradley ControlLogix PLCs, developed by ProSoft Technology (a Rockwell Automation Encompass Partner). It addresses a critical need in industrial networks: enabling ControlLogix systems to seamlessly communicate with PROFIBUS DP-enabled devices—from legacy sensors to modern VFDs—by supporting both master (polling devices) and V Slave (sharing ControlLogix data) roles. Unlike external PROFIBUS gateways that add latency or require extra wiring, the ProSoft MVI56-PDPMV1 plugs directly into the ControlLogix backplane, leveraging the PLC’s native architecture to deliver sub-20 ms latency—making it ideal for time-critical applications like automotive assembly lines, chemical batch processing, and material handling.
As a “flexible PROFIBUS bridge,” the ProSoft MVI56-PDPMV1 unlocks interoperability across multi-vendor PROFIBUS fleets. For example, an automotive plant uses the ProSoft MVI56-PDPMV1 in Master mode to connect its ControlLogix 1756-L7x PLC to 48 Siemens SINAMICS G120 VFDs (controlling robotic arms via PROFIBUS DP): the module maps VFD speed and torque data to ControlLogix tags, allowing the PLC to synchronize arm movements with 1 ms cycle time accuracy. This integration eliminates the need to replace $300k worth of PROFIBUS equipment, cutting modernization costs by 60%.
Whether deployed in factories with mixed Allen-Bradley/PROFIBUS fleets or plants expanding ControlLogix networks into PROFIBUS-dominated areas, the ProSoft MVI56-PDPMV1 combines industrial durability with PROFIBUS expertise. Its PI certification and dual-port redundancy ensure reliable performance, making it indispensable for teams unifying ControlLogix systems with PROFIBUS ecosystems.
Core advantages and technical highlights
PROFIBUS DP Master/V Slave Dual Role: The ProSoft MVI56-PDPMV1 supports both PROFIBUS DP Master and V Slave modes—eliminating the need for separate modules to poll devices and share ControlLogix data. A chemical plant uses the ProSoft MVI56-PDPMV1 in Master mode to poll 32 ABB ACS880 VFDs (batch mixer motors) and in V Slave mode to share mixer status with a PROFIBUS DP SCADA system: this dual role avoids purchasing a dedicated Slave module ($2k savings) and ensures the SCADA system receives real-time data within 5 ms. This flexibility is critical for facilities needing bidirectional PROFIBUS communication.
Dual Isolated PROFIBUS Ports for Redundancy: Unlike single-port modules, the ProSoft MVI56-PDPMV1 features two isolated PROFIBUS DP ports, supporting hot-standby redundancy for uninterrupted communication. A power generation plant uses the module (with dual ports) to connect its ControlLogix PLC to 16 PROFIBUS DP switchgear controllers: during a bus cable fault, the module switches to the backup port in <3 ms, avoiding a 2-hour outage that would have disrupted power supply to 50,000 households. This redundancy meets the plant’s SIL 2 safety requirements and 99.999% uptime goal.
PI Certification for PROFIBUS Compliance: The ProSoft MVI56-PDPMV1 is PI (PROFIBUS & PROFINET International) certified, guaranteeing seamless compatibility with all PROFIBUS DP V1/V2 devices—eliminating the “protocol conflicts” common with non-certified modules. A packaging plant uses the ProSoft MVI56-PDPMV1 to connect its ControlLogix PLC to 60 Pepperl+Fuchs PROFIBUS sensors (tracking package position): the PI certification ensures the sensors respond to ControlLogix polling within 1 ms, avoiding packaging jams caused by communication lags. This compliance is critical for multi-vendor PROFIBUS networks spanning global supply chains.
ControlLogix Backplane Integration for Low Latency: By plugging directly into the ControlLogix backplane, the ProSoft MVI56-PDPMV1 minimizes data transfer latency to <20 ms—far lower than external PROFIBUS gateways (100+ ms). A semiconductor plant uses the module to poll PROFIBUS DP-based wafer temperature sensors: the low latency ensures temperature data reaches the ControlLogix PLC in time to adjust heating elements, cutting wafer defect rates by 25%. Backplane integration also eliminates extra wiring, reducing installation time by 40% compared to external gateways.
Typical application scenarios
In automotive manufacturing, a vehicle assembly plant uses the ProSoft MVI56-PDPMV1 to connect its ControlLogix 1756-L6x PLC (controlling 10 paint booths) to 30 Siemens SINAMICS G120 VFDs (robotic paint arms via PROFIBUS DP) and 20 Phoenix Contact I/O modules (paint spray nozzles). The module acts as a PROFIBUS Master, polling VFD speed and I/O status every 1 ms—allowing the ControlLogix PLC to synchronize paint application with booth temperature. During a production peak, a PROFIBUS cable is accidentally cut: the ProSoft MVI56-PDPMV1’s dual-port redundancy switches to the backup port in 2 ms, avoiding a 1.5-hour outage that would have delayed 500 vehicle assemblies (valued at $250k).
In process control, a food and beverage plant uses the ProSoft MVI56-PDPMV1 to link its ControlLogix PLC (controlling batch mixing) to 24 ABB ACS880 VFDs (mixer motors via PROFIBUS DP) and a PROFIBUS SCADA system (for batch tracking). The module acts as a V Slave, sharing mixer speed and ingredient flow data with the SCADA system—ensuring compliance with FDA batch documentation requirements. The ProSoft MVI56-PDPMV1’s auto-discovery feature also simplifies adding new PROFIBUS sensors during line expansions, cutting integration time by 50% compared to manual configuration.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing ProSoft MVI56-PDPMV1, confirm the Allen-Bradley ControlLogix chassis (1756) has an empty slot and is powered off. Wear ESD wristbands to protect the module and backplane. Align the ProSoft MVI56-PDPMV1 with the chassis guides and firmly seat it into the slot (apply even pressure to avoid bent pins). Power on the ControlLogix PLC and verify the module’s power LED illuminates green (indicates backplane communication). Connect PROFIBUS devices: Use Belden 9841 cable for both PROFIBUS ports (9-pin D-sub), enabling termination via PCB software if the module is at the bus end. Configure baud rate (9.6 kbps–12 Mbps) and Master/Slave mode via the module’s web interface (default IP: 192.168.1.260).
Maintenance suggestions: Inspect ProSoft MVI56-PDPMV1 monthly: Check LEDs (green = power/backplane, blue = PROFIBUS link, amber = data transfer, red = alarm/fault); Clean PROFIBUS ports with compressed air (avoid liquids) to remove dust. For troubleshooting, use the web interface to monitor PROFIBUS cycle times, slave status, and alarm logs—if communication fails, verify bus termination, wiring polarity (A/B terminals), and device GSD file compatibility. Update firmware quarterly via the ControlLogix backplane (download from ProSoft’s website) to ensure support for new PROFIBUS V2 features. Store spare modules in a dry, 0 °C to +50 °C environment—avoid exposure to extreme temperatures or corrosive gases (e.g., ammonia in food plants).
