FAQ
FAQ
Q1: What is the MVI56-MCM module?
It is a ProSoft ControlLogix communication module that provides Modbus RTU and ASCII Master/Slave functionality for Allen-Bradley PLC systems.
Q2: Which PLC platform does it support?
It is designed for the Allen-Bradley ControlLogix platform using the 1756 chassis.
Q3: How many serial ports does it have?
It has two isolated serial ports, configurable as RS-232 or RS-485.
Q4: What protocols does it support?
It supports Modbus RTU and Modbus ASCII in both Master and Slave modes.
Q5: How does it communicate with the PLC?
It exchanges data through the ControlLogix backplane using I/O memory mapping and Add-On Instructions (AOI).
Q6: Does it require special programming?
No, it uses pre-built AOI blocks and configuration in Studio 5000 without custom firmware programming.
Q7: What is it commonly used for?
It is widely used for connecting Modbus field devices such as energy meters, VFDs, analyzers, and sensors into ControlLogix systems.
Q8: Why is it still widely used?
Because it provides a stable, simple, and well-supported way to integrate Modbus RTU networks into Rockwell Automation ControlLogix platforms.
