The MVI46 Modbus Plus Dual Port Network Interface Module allow Rockwell Automation SLC processors to connect directly on Modbus Plus networks as a peer. The module acts as an input/output module between the Modbus Plus network and the processor. Compatible devices can be found in most industries and include devices such as drives, relays and power monitor hardware.

Features and Benefits

Compatible devices include not only Modicon PLCs (most of which support the Modbus Plus protocol) but also a wide assortment of end devices licensed through the ModConnect Program. The MVI46-MBP module acts as an input/output module between the Modbus Plus network and the Rockwell Automation backplane. The data transfer from the SLC processor is asynchronous from the actions on the Modbus Plus network. A 4000-word register space in the module exchanges data between the processor and the Modbus Plus network.

These modules allow Rockwell Automation platforms to connect directly on Modbus Plus networks as a peer. In addition, the modules act as slaves to processors that must read/write data from the module's memory.

Crossing all industrial boundaries, potential applications include the connection of Rockwell Automation processors to Modicon processors, and the connection of Modbus Plus-speaking devices, such as drives, relays, and power monitor hardware, to the Rockwell Automation backplanes.
