The CPU is able to save a PLC program in persistent memory. This means that when
PLC Program Persistency is ENABLED, the program will be automatically loaded and
executed at start-up. Every time the user downloads a new program to the CPU
(
during the development activities), it is saved in the persistent memory and at next
device start up, the last downloaded program will be executed. Saving a program in
persistent memory is a time consuming activity. For that reason the user may want to
disable the automatic program save to make development activities more efficient. It
can be useful to prevent execution of any program at start-up. Selecting the item
“
Erase PLC program ” the retentive memory area reserved to store PLC programs is
erased. This activity take several seconds. When the “
Persistency setup menu ”
screen reappears then the memory has been erased.
