Hello Matt; You could do an Online/offline block compare of the backup program and the one loaded in the PLC. You would get errors based on the fact that the symbols are not uploaded from the CPU to the PC, but at least you would see if major blocks and data are missing. This should reassure you or at least show you that your fears are justified... Here is how Siemens introduces the subject: http://support.automation.siemens.com/WW/view/en/18652056 Programming with STEP 7 9.3.5 Comparing Blocks Introduction To compare blocks that are in different locations, you can start the block comparison process in either of the following ways:
The following sections explain how the block-comparison process functions. In the following discussion, a distinction is maintained between logic blocks (OBs, FBs, FCs) and data blocks (DBs). Hope this helps, Daniel Chartier |
