I'm a bit of a Siemens newbie so this should be an easy question for some of you.
I have an oldish copy of an S7 Project that I need to refresh with the current code in the field. There does not seem to be any option for doing a complete Upload of a processor to an existing project so the best thing I could think of was to go online, select all of the blocks and do a Right-Click, PLC -> Upload to PG. After doing this I now get the error "The symbol information for the block is invalid" when I open any block.
I know I can create a new Project and then do a PLC -> Upload Station to PG but how do I incorporate the Symbol Information from the old project.
In short what is the best procedure for doing a complete upload of an S7 CPU, including all CPU settings etc, while retaining the Symbol information/documentation from the offline file.
We are using Step 7 Pro v5.4
Thanks
