5.1 Product Specifications

The MVI46 Modbus Master/Slave Communication Module allows Rockwell

Automation

SLC

processors to interface easily with other Modbus protocol

compatible devices.

The module acts as an input/output module between the Modbus network and

the SLC 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.

5.1.1 General Specifications

 Single Slot - 1746 backplane compatible (Local or extended I/O rack only.

Remote rack not supported)

 The module is recognized as an Input/Output module and has access to

processor memory for data transfer between processor and module using

M0/M1 files

 Ladder Logic is used for data transfer between module and processor

 Configuration data obtained through user-defined ladder. Sample ladder file

included
