Modbus Master/Slave Communication Module MVI71-MCM The MVI71 Modbus Master/Slave Communication Module allows PLC processors to interface easily with other Modbus protocol compatible devices. Compatible devices include not only Modicon PLCs (which all support the Modbus protocol) but also a wide assortment of end devices. The module acts as an input/output module between the Modbus network and the Rockwell Automation backplane. The data transfer from the processor is asynchronous from the actions on Modbus Master/Slave the Modbus network. A 5000-word register space in the module exchanges data between the processor and the Communication Module Modbus network. MVI71-MCM Applications using the Modbus Master/Slave Features and Benefits Communication Module can be found in many industrial The inRAx Modbus Master/Slave sectors and in the following applications Communication Module is designed to allow PLC processors to interface easily with Modbus protocol- • Foreign device data concentrator compatible devices and hosts. • Pipelines and offshore platforms • Food processing The MVI71-MCM module acts as an input/output module • Mining between the Modbus network and the Rockwell • Pulp and paper Automation backplane. The data transfer from the PLC processor is asynchronous from the actions on the • SCADA communications Modbus network.

One Local or remote rack hundred commands are supported on each port. Backplane current 800 mA @ 5 V Additionally, the master ports have an optimized polling load characteristic that polls slaves with communication problems less frequently. The PLC processor can be Operating 0 to 60°C (32 to 140°F) programmed to control the activity on the port by actively temperature selecting commands from the command list to execute Storage temperature -40 to 85°C (-40 to 185°F) or issuing commands directly from the ladder logic.
