The MVI56E Modbus Master/Slave Enhanced Communication Modules allow Rockwell Automation ControlLogix processors to easily interface with devices using the Modbus RTU/ASCII serial communications protocol.
The MVI56E-MCM and MVI56E-MCMXT act as input/output modules on the ControlLogix backplane, making Modbus data appear as I/O data to the processor. Data transfer to and from the processor is asynchronous from the communications on the Modbus network. Two independently-configurable serial ports can operate on the same or different Modbus networks. Each port can be configured as a Modbus Master or Slave, sharing the same user-controlled 5000-word database.
The two modules are functionally the same. The MVI56E-MCM is designed for standard process applications. The MVI56E-MCMXT is designed for the Logix-XT control platform, allowing it to operate in extreme environments, at higher operating temperatures, and has a conformal coating to protect it from harsh or caustic conditions.
ProSoft Configuration Builder (PCB) provides a PC-based software configuration solution for quick and easy management of ProSoft Technology modules, as well as viewing module and network diagnostics. PCB provides an excellent diagnostic tool for the module when used with CIPconnect technology, providing communication over local and remote chassis. The Setup Guide and sample configuration provide a quick start up with step by step instructions on how to move data from the Modbus network to the controller.
