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

between the SLC processor, the MVI46-DFCM module and the DF1 network.

All data transferred between the module and the processor over the backplane is

through the M0 and M1 files. Ladder logic must be written in the SLC processor

to interface the M-file data with data defined in the user-defined data files in the

SLC. All data used by the module is stored in its internal database. The following

illustration shows the layout of the database:

1 2 ... 52 53 54 55 56 57 58 59 60 61 62 ... 102 103
