The sample program included with your MVI56-MCM Module contains predefined
controller tags, configuration information, data types and ladder logic that allow
the module to communicate between the ControlLogix processor and a network
of Modbus devices. For most applications, the sample program will work without
modification.

The sample program for your MVI56-MCM module includes custom tags, data
types and ladder logic for data I/O, status and command control. For most
applications, you can run the sample program without modification, or, for
advanced applications, you can incorporate the sample program into your
existing application.
The ProSoft Solutions CD provides one or more versions of the sample ladder
logic. The version number appended to the file name corresponds with the
firmware version number of your ControlLogix processor. The firmware version
and sample program version must match.
The ProSoft Solutions CD-ROM included in the package with the module
contains ladder logic, product manuals and utility programs for all ProSoft
