Whenever I create a new variable in a DB, all viriáveis ​​this block are initialized

Hi

DB's are designed to work that way only.

You can create a set of dummy variables and download it in PLC for one last time.

So when even you want to use a new variable you can pick an unsed Dummy variable.

When DB is updated, its values are initialized.

You can upload the DB you want to update with new variables from the work memory, and then save it as another DB (save as) - buffer DB. This allows you to back up your actual values offline.

Add new variables to the existing DB, and after you download it, just copy the actual values from the buffer DB to the updated DB.

After that you can erase the DB that served you as a buffer.

Anyway, you can also build a big DB in advance, and just change symbol names inside every time you add a new variable.

Hi


According to the responses it seems that there are nopractical solutions to solve the problems. I'm a programmer from other brands and this problem does not arise.
It seems to me that a much more practical solution is monitorize DB and copy the column of my current values ​​for the column of the default values​​.
This option could be suggested automatically by the software, as further facilitated.


Thanks
