What does this S7 icon mean?

[Bobbeh]

I was just using the compare function in S7 to compare two almost identical function blocks and when I returned to simatic manager I noticed the function block icon had changed.

It almost looks like a little yellow warning symbol next to it but I cant see any errors anywhere.

Any ideas?

Was the comparison between two projects or online/offline ?

They were both offline.

I've actually found out it was caused by an attribute being set in block properties. Somehow the block had gained an attribute during comparison..must have mashed too many keys at once or something.

Still, the icon is gone now, cheers for the reply.
