ProSoft Technology MVI56-MCM Modbus Master/Slave Communication Module

The ProSoft Technology MVI56-MCM Modbus Master/Slave Communication Module is a ControlLogix interface communications module that enables Modbus Master and Modbus Slave communications within a Rockwell Automation environment. It provides a dedicated Modbus communication path for Allen-Bradley ControlLogix PLCs, allowing the controller to exchange data with Modbus devices as either a master polling devices or a slave responding to master requests. This part is specifically identified by the MVI56-MCM model number and sits among ProSoft’s Modbus interface solutions for ControlLogix, offering a compact, purpose-built solution for Modbus connectivity without changing the core PLC hardware. Typical use cases include integrating Modbus-enabled instruments and devices into a ControlLogix-driven control system and enabling data exchange with SCADA or other supervisory systems that rely on Modbus connectivity. By supporting Modbus Master/Slave operation, the module helps engineers design hybrid networks that combine Rockwell Automation equipment with Modbus devices, expanding interoperability across industrial automation architectures.
