Note!
Some projects, program examples, as well as Lenze templates use areas of the
persistent memory. They also are labelled by "LenzeInternalUse" and must not
be altered by the user.
Example: Saving current position fail−safe
By means of an AT declaration, for instance, the variable can be directly connected to the
address of a persistent variable in its current position, and like this can save the position
fail−safe:
g_dnActualPosition_p
AT%QD171.6:DINT;
