The internal database of the DFNT module is used as the source (read requests)
and destination (write requests) for requests from remote clients. Access to the
database depends on the MSG command type executed to interface with the
database. The following table defines the relationship of the module’s internal
database to the addresses required in the MSG instructions:

When using PLC5 or PLC commands, access to the database is through
simulated 'N' files. For example, to access database element 3012, use the file
address of N13:12. The module simulates N-files in the internal database. The
following table lists the relationship between the N-
files and the module’s internal
database registers:
