While using Step 7 basic to create the program for theS7-1200, I am encountering the following problem: When using the MOVE instruction to put an integer number to global DB, I receive the error stating: "The MOVE instruciton only allows data blocks based on SDT/UDT" The same move instruction and definition of the global (shared) data block works fine in Step 7. I have tried a few different things, like creating a different DB that has the "Symbolic Acces Only" option unchecked, but it does not make a difference. Attached is a screen shot of the network described. Any help would be greatly appreciated. Attachment Network.JPG (335 Downloads)
