ProSoft MVI46-MCM Modbus RTU/ASCII Master Slave Module

ProSoft MVI46-MCM SLC 500 Modbus Master/Slave Network Interface Module

Product Overview

The ProSoft MVI46-MCM (MV146-MCM) is a specialized Modbus communication interface designed for Allen-Bradley SLC 500 series PLCs. Functioning as a high-performance bridge, this single-slot module allows SLC processors to communicate seamlessly with Modbus RTU and ASCII devices. Whether acting as a Modbus Master or Slave, the MVI46-MCM handles complex data transfers independently of the PLC processor, ensuring that network traffic does not degrade the controller's scan time. It is an essential component for integrating third-party hardware—such as power meters, variable frequency drives (VFDs), and flow controllers—into a Rockwell Automation environment.

Industrial Application Scenarios

• Energy Management: Collecting real-time power consumption data from Modbus-enabled digital power meters.

• Process Automation: Interfacing with chemical analyzers and temperature controllers in pharmaceutical or food processing.

• HVAC & Building Control: Integrating boiler and chiller controllers into an SLC-based central monitoring system.

• SCADA Integration: Functioning as a Modbus Slave to provide SLC data to a higher-level Master SCADA system.
