DM Area Word Allocations

Software switches, PROFIBUS Master Unit status, and Slave Status data are
allocated in the CIO Area according to the unit number, as shown below. Soft-
ware switches are bits used as commands from the PLC CPU to the PROFI-
BUS Master Unit to enable executing Unit functions.

The DM area words which are allocated for the PROFIBUS Master Unit are
not used, i.e. no data is exchanged between an allocated DM area and the
Unit. However, the allocated area is reserved for use in a future extension of
the Unit. Therefore, using this area for user data is not recommended.
