Rockwell ProSoft MVI56-MCM Modbus master-slave communication module

The MVI56 Modbus Master/Slave Communication Module allows Rockwell Automation® ControlLogix® processors to interface easily with other Modbus protocol compatible devices.

The module acts as an Options module between the Modbus network and the ControlLogix backplane. 

Compatible devices include not only Modicon® PLCs (almost all support the Modbus protocol) but also a wide range of process and control devices from a variety of manufacturers.

Many SCADA packages also support the Modbus protocol.
