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

between the CompactLogix processor, the MVI69-GSC module and the network.

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

CompactLogix processor to interface the input and output image data with data

defined in the Controller Tags. All data used by the module is stored in its internal

database. The following illustration shows the layout of the database:
