Hi Community,
I see one annoying issue with variable status inside SafeDESIGNER, quite often I see the error message:

but I’m online with my CPU:

and I’m online with SafePLC:

Regarding communication settings:

Any idea?
Thanks

As soon as I have completed in correct way the sequence for commissioning the safety prj reported in the post: SafeDESIGNER 6.4.1.0: I can’t open Variable status because of internal check said “Projects a re different” - Ask Questions / Controls & Vision - B&R Community I don’t see any more the connection issue.
