ProSoft MVI56-PDPS ControlLogix PROFIBUS DP Slave Communication Module

Description

The ProSoft MVI56-PDPS is a high-performance PROFIBUS DP Slave communication module designed for seamless integration within Rockwell Automation ControlLogix 1756 chassis. This single-slot module acts as a native I/O device, allowing ControlLogix processors to communicate directly with a PROFIBUS DP Master network. By offloading protocol-specific processing tasks from the main PLC CPU, the MVI56-PDPS ensures efficient data exchange and optimized control performance in demanding industrial environments.

Features

• Native Integration: Functions as a standard ControlLogix I/O module, allowing for direct memory access and ladder logic-based data management.
• PROFIBUS DP V0 Slave: Supports robust communication with PROFIBUS DP Master devices.
• Automatic Baud Rate Detection: Automatically detects network speeds ranging from 9.6 kbps to 12 Mbps.
• Simplified Configuration: Uses a dedicated text file for register mapping, compatible with RSLogix 5000 and Studio 5000 environments.
• High-Speed Processing: Onboard processor handles complex protocol tasks to reduce system latency.

Applications

This module is engineered for mission-critical industrial applications, including oil and gas refineries, power generation facilities, and large-scale mining operations. It is ideal for bridging ControlLogix-based automation systems with third-party PROFIBUS-enabled field devices, drives, or remote I/O.

Technical Specifications

Installation Guidelines

• Power Down: Always remove power from the ControlLogix chassis before inserting or removing the module to prevent electrical damage.
• Chassis Placement: The module can be installed in any available slot in a 1756 local or remote rack. Ensure the module is fully seated and the locking tabs are engaged.
• Grounding: Ensure the ControlLogix chassis is properly grounded according to local electrical codes to minimize EMI/RFI interference.
• Wiring: Use shielded PROFIBUS-rated cable for the DB9 connection. Keep communication cables routed away from high-voltage power lines to maintain signal integrity.
• ESD Precautions: Handle the module by the edges and avoid touching the backplane pins to prevent electrostatic discharge damage.

FAQ

What programming software is required to configure the MVI56-PDPS?

The module is configured using a text file downloaded to the module. It is designed to be compatible with standard Rockwell Automation programming environments, including RSLogix 5000 and Studio 5000, using ladder logic for data exchange.

Does this module require a separate power supply?

No, the MVI56-PDPS draws its required power directly from the ControlLogix backplane. It consumes 800 mA at 5 VDC and 3 mA at 24 VDC.
