Hello all,

I have a problem with a SFC:

When doing an Update Block types from Library to System Simatic Manager crashed.

Now I am left with a SFC block which I cannot delete, because of the error message "text cannot be read" and I cannot compile this CPU anymore. I therefore would have to delete the SFC and instanciate again, but I cannot delete the SFC block.

When I open the problematic SFC I get the message "Text cannot be read". When I go to Block Contacts I get the same error message twice, then I am told there are no Block Contacts - which is wrong, there are several there, but Simatic Manager cannot read them anymore and I cannot delete them anymore. If I click Update Block Contacts, I see them all and can Update them but the situation is the same, in main Window the block contacts are gone.

I think I would simply have to delete all the block contacts to make this SFC deletable and everything returns to normal.

Could Anybody tell me how to delete this SFC block? Doing so always gives me the error message "text cannot be read" without actually deleting the block.

Thank you for your suggestion, I did that numerous times but PCS7 will not update it anymore to a state where I can delete the problematic SFC in CPU.
