The block must be configured in the same
sampling time
as the blocks, connected via the pointer interface
(CFC connection via connections PTR).
This can only be used for the FM 458-1 DP!
Several S7WR_P blocks can be configured.
Although this is not a typical application, it can
make sense if, for example, the 128 byte area
should be written in several blocks or if data is
required in different sampling times.
