4.1.4 Data saving
Saving data internally
The data in the memory backed up for a limited period can be saved internally in the perma-
nent memory of the control system.
An internal data backup should be carried out if the control system has been switched off for
more than 50 hours (at least 10 min/day with controller ON).
It is recommended to carry out internal data saving whenever important data changes have
been made.
