Kelu Posts: 88 Rating: (12)	Hello, I would like to know how I can compare blocks between 2 differents projects? like it was possible in Step7 v5.5. I see we have Online/Offline or Offline/Offline but only possible between 2 devices in the same project. Thank you for answers. Best regards, Kelu

Best regards, Kelu My answer is likely not normal nor ideal but it worked for a recent problem recovering changes made that resulted in a corrupted project. What I did was load the last good backup into my plc, verified it still performed sufficient for the programming within it. Next I opened the corrupted project that I could not download but could open and view. Now I went online and compared online to offline. That did exactly what you would expect and helped me identify changes needed in the working backup copy of the project. Hope this is useful for your own efforts.

Kelu Posts: 88 Rating: (12)	Hello huggy_d1, Yes, thank you, it is a solution but like you say it's not very conventional... In fact actually there isn't any tools to do that properly without using a loaded CPU? Best regards, Kelu,

You can compare all moduls and you can set a filter during the compare. With best regards Cicero

Thank you Rgds, When I searched the online portal help for V12 SP1 Update 2, I found this search topic: Comparing reference projects It explains how to do what you are looking for.
