The following illustration shows the data transfer method used to move data

between the ControlLogix processor, the MVI56E-MCMR module, and the serial

network. This applies only for the scheduled I/O data.

As shown in the diagram, all data transferred between the module and the

processor over the backplane is through the Input and Output Images. Ladder

logic must be written in the ControlLogix processor to interface the Input and

Output Image data defined in the controller tags. The user is responsible for

handling and interpreting all data received on the application ports and

transferred to the Input Image.
