Description
Description
The ProSoft MVI46-MCM is a high-performance communication module designed to allow Rockwell Automation SLC 500 processors to interface seamlessly with Modbus protocol-compatible devices. Acting as an input/output module between the Modbus network and the Allen-Bradley backplane, it facilitates asynchronous data exchange. The module features a 5000-word register space for efficient data transfer, supporting both Master and Slave configurations across its communication ports.
Features
- Dual-port interface supporting RS-232, RS-422, or RS-485 physical layers.
- Configurable as a Modbus Master or Slave device.
- Supports up to 100 commands per port in Master mode.
- Optimized polling characteristics to manage communication with problematic slave nodes.
- Direct ladder logic control for command execution.
- Single-slot module design for Allen-Bradley 1746 chassis.
Applications
- SCADA system integration and data concentration.
- Pulp and paper mill process control and motor drive management.
- Mining and heavy material handling, including conveyor and crushing equipment.
- Burner and boiler management systems.
- Food and beverage processing, including weigh scales and temperature controllers.
- Automotive manufacturing, including robotic welding and CNC station monitoring.

Installation Guidelines
- Ensure the SLC 500 processor is powered down before inserting or removing the module from the chassis.
- The module must be installed in a local or extended I/O rack (0-3) of the SLC 500 system; it does not support remote I/O rack installation.
- Use appropriate shielded cabling for RS-422/485 connections to minimize EMI interference.
- Ensure proper grounding of the chassis to maintain signal integrity.
- Follow standard ESD precautions when handling the module to prevent damage to internal circuitry.
FAQs
What is the MVI46-MCM?
The ProSoft Technology MVI46-MCM is a Modbus Communication Module for Allen-Bradley SLC 500 systems, supporting Master or Slave protocols on two configurable serial ports.
Can the MVI46-MCM be placed in a remote rack?
No, it must reside in the local or extended I/O rack (0-3) of the SLC 500 system.
What is the difference between MVI46-MCM and 3150-MCM?
