Description

The ProSoft MVI69-MCM is a high-performance Modbus Master/Slave communication module designed specifically for the Rockwell Automation CompactLogix platform. This single-slot module enables seamless integration of Modbus-enabled devices into a ControlLogix or CompactLogix architecture, acting as a bridge between the PLC and external serial devices such as drives, sensors, and instrumentation.

Features

• Compatible with Rockwell Automation CompactLogix systems.
• Supports both Modbus Master and Slave configurations for flexible network integration.
• Data transfer managed via standard ladder logic for simplified programming.
• Supports baud rates ranging from 110 to 115K baud.
• Configurable node addressing from 1 to 247.
• Standard 1769 single-slot form factor for easy backplane mounting.

Applications

This module is widely used in industrial automation environments requiring serial communication, including water and wastewater treatment, oil and gas processing, power generation, and general manufacturing where legacy Modbus devices must interface with modern Allen-Bradley controllers.

Technical Specifications

Installation Guidelines

• Ensure the CompactLogix system power is disconnected before installing or removing the module.
• Slide the MVI69-MCM into the designated 1769 chassis slot and secure it using the integrated locking mechanism.
• Use shielded twisted-pair cabling for serial connections to minimize EMI interference in high-noise industrial environments.
• Verify that the module is properly seated in the backplane to ensure reliable communication with the CPU.
• Configure the module parameters using the appropriate ProSoft configuration software or ladder logic integration files.

FAQ

Q: Is this module compatible with all CompactLogix processors?
A: The MVI69-MCM is designed for the 1769 CompactLogix platform. Please verify your specific processor firmware and backplane compatibility before installation.

Q: How is data transferred between the module and the PLC?
A: Data transfer is handled via ladder logic, allowing the PLC to read and write Modbus registers directly through the module's memory mapping.
