The MVI69-PDPS is a high-performance Profibus DP communication gateway for Rockwell Automation CompactLogix systems. Acting as a Profibus DP Slave, it enables a CompactLogix controller to appear as a standard node on an existing Profibus network, allowing deterministic, high-speed data exchange with a Profibus DP Master.
The module autonomously handles the Profibus protocol, reducing the CPU load on the CompactLogix processor and ensuring reliable integration in hybrid automation environments.

The MVI69-PDPS is commonly used to integrate CompactLogix systems with Profibus DP networks in:
Automotive assembly lines
Food and beverage packaging systems
Water and wastewater treatment plants
It allows local CompactLogix-based skids or machinery to interface seamlessly with plant-wide Profibus infrastructures without requiring major system redesign.
Does this module require a separate power supply?
No. The MVI69-PDPS draws power from the CompactLogix 1769 backplane. Ensure the backplane power supply can provide 800 mA for the module.
How is the Profibus address assigned?
The slave address can be configured via the ProSoft Configuration Builder (PCB) software through the CFG port or, in some versions, dynamically through PLC ladder logic.
