Hi
I am working with a siemens S7 PLC which was not having comments in the program.There was a similar program with symbols but having some differences. All the symbols were copied and pased to existing program.Now I can see the comments in the program except the comments in DBs. I dont want to copy the DB with comments to PLC as the many of the actual values in both DBs are not same. Is there any way to go online and copy only the actual values and paste in the DB having comments. And then download this DB to PLC.
It can be done manually also but there are lot of such DBs.

Any trick if any ,please share.
