FAQ
FAQ
Q1: What is the MVI56-MCMR module?
It is a ProSoft ControlLogix communication module that enables Modbus RTU/ASCII Master/Slave communication with reduced data block architecture to improve efficiency.
Q2: What is the difference between MVI56-MCM and MVI56-MCMR?
The MCMR version uses a reduced data block design, which lowers backplane traffic and improves performance in remote or bandwidth-limited systems.
Q3: Which PLC platform does it support?
It is designed for Allen-Bradley ControlLogix systems using the 1756 chassis.
Q4: How many serial ports does it have?
It has two isolated serial ports, configurable as RS-232 or RS-485.
Q5: What communication protocols are supported?
It supports Modbus RTU and Modbus ASCII in both Master and Slave modes.
Q6: How does it communicate with the PLC?
It exchanges data via the ControlLogix backplane using I/O mapping and Add-On Instructions (AOI).
Q7: What is it typically used for?
It is used for industrial Modbus integration such as energy meters, VFDs, analyzers, and distributed field devices, especially in larger networks.
Q8: Why use the reduced data block version?
Because it reduces backplane and network overhead, making it more suitable for remote racks, large polling systems, or constrained communication environments.
