How can the values written to the DB block in WinCC be saved?
Thread Content
The values from the IO area in WinCC are written to a parameter in a DB block, but after the PLC is reset, the values in that DB block revert to their default values. How can I keep the values written by WinCC without them returning to their default values? ? Thank you
In step 7, switch to online mode, then copy and paste the online DB to overwrite the offline DB
The method for the 2nd floor is relatively feasible, but the downside is that after the online DB is copied to an offline directory, it no longer contains any symbolic names or annotations. If you’re concerned about this, you can manually make the necessary changes. This copying method saves the actual values from the online system in the offline program; however, if the PLC is reset, the DB inside will overwrite those actual values with their initial values, requiring you to download the copied DB again
