Allen-Bradley MVI69-MCM Modbus Communication Module

Allen-Bradley MVI69-MCM Modbus Communication Module

Description

MODBUS is a widely-used protocol originally developed by Modicon in 1978. Since that time, the protocol has been adopted as a standard throughout the automation industry.

The original MODBUS specification uses a serial connection to communicate commands and data between Master and Slave devices on a network. Later enhancements to the protocol allow communication over other types of networks.

MODBUS is a Master/Slave protocol. The Master establishes a connection to the remote Slave. When the connection is established, the Master sends the MODBUS commands to the Slave. The MVI69-MCM module can work as a Master and as a Slave.

The MVI69-MCM module also works as an input/output module between itself and the Rockwell Automation backplane and processor. The module uses an internal database to pass data and commands between the processor and Master and Slave devices on MODBUS networks.
