ProSoft MVI69-PDPS CompactLogix Profibus DP Slave Communication Module

Product Description

The MVI69-PDPS (ProSoft Technology) is a high-performance Profibus DP Slave communication module for Allen-Bradley CompactLogix systems. It allows a CompactLogix processor to operate as a Profibus DP Slave, enabling seamless data exchange with Profibus Masters such as Siemens PLCs or DCS controllers. By integrating the MVI69-PDPS into the I/O rack, engineers can bridge Rockwell Automation environments with standardized European fieldbus networks.

This module functions as a backplane-compatible plug-in, appearing as a standard I/O module to the processor. It manages the timing and protocol complexities of Profibus DP, offloading communication overhead from the main CPU. With support for baud rates up to 12 Mbps and an internal 400-word data map, it delivers reliable, high-speed performance for time-critical industrial applications.

Technical Specifications

Application Scenarios

The MVI69-PDPS is ideal for hybrid automation environments where a CompactLogix system must communicate with a Siemens-based Profibus Master. Typical applications include:

• Packaging machinery

• Automotive assembly lines

• Water treatment and process skids

It is particularly useful in cross-vendor systems where seamless interoperability is required.

Frequently Asked Questions

Q: Does the MVI69-PDPS require a GSD file for configuration?
A: Yes. A ProSoft-provided GSD file is needed to integrate the module into a Profibus Master’s configuration tool (e.g., TIA Portal or Step 7). The GSD file defines the module’s capabilities to the Master.

Q: Can I configure the module through the CompactLogix backplane?
A: No. While data exchange occurs via the backplane, initial protocol setup and diagnostics are performed through the dedicated RS-232 Configuration (CFG) port using ProSoft Configuration Builder software.
