Saving S7 actual data to the memory card

sonarbell · Nov 16, 2009

Anyone got any ideas how to save my actual values to the initial values in my DB's without doing it one by one. Or will saving RAM to ROM be enough.
My problems is when the customer does a master reset it loads the initial values from the DB's and not the actual.

Its a 300 series CPU ..

Your help is appreciated as always.

What is that "master reset" ? is it enought to make db:s retentive?

Master reset deletes all retentive stuff too. Thats my problem. I think Ive done it anyway. I copied RAM to ROM in the PLC menu list and tried it.. Seems to have worked. Stroke of luck eh !!

'Copy RAM to ROM' will save your actual values as new initial values.
