Description

Modbus Plus Dual Port Network Interface Module for ControlLogix

MVI56-MBP

The MVI56 Modbus Plus Dual Port Network Interface Module allow Rockwell Automation ControlLogix 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 (which all support the Modbus Plus protocol) but also a wide assortment of end devices licensed through the ModConnect Program. The MVI56-MBP module acts as an input/output module between the Modbus Plus network and the Rockwell Automation backplane. The data transfer from the ControlLogix 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.

 

Applications

Applications using the Modbus Communication Module can be found in many industrial sectors and in the following applications:

  • Foreign device data concentrator
  • Pipelines and offshore platforms
  • Food processing
  • Mining
  • Pulp and paper

Global Data Specifications

The MBP module actively exchanges global in (32 words max. per node) and global out (32 words max.) data on the Modbus Plus network. Priority is given to these data types to provide a high speed mechanism for the transfer of control data.

Modbus Slave Mode Specifications

  • Supports broadcast commands from host
  • Communication error codes returned to ladder logic

 

Modbus Master Mode Specifications

  • Command list support of up to 100 commands
  • Conditional and continuous command list polling
  • Each command list entry is fully configurable for function register to/from addressing and word/bit count/word and byte swap
  • Event driven bit and register write commands (ladder logic controlled)
  • Supports sending of broadcast commands
  • Communication status error codes returned to ladder logic on a per command basis
