6-2-7 DM Area
This area is used in word units. The DM Area is contained in I/O memory (i.e.,
areas that can be freely read and written from the ladder program) and areas to
which functions are allocated.
The words in this area do not have any special functions and can be used as
required in programming. They can be read and written to using instructions or a
Programming Device.
