Call
The function must be executed after a startup (power on) of the module or CPU. You should
therefore insert it, for example, in the restart OB (OB100) and the removal/insertion OB
(OB83) or call it in the initialization phase of your user program. This ensures that your user
program does not access obsolete data after a CPU or module restart.
