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
