perhaps a stupid question, but when I look at your example it's OK, but I copied the programblocks to my project and some things don't work. When I compile the programblocks, I get errors "Library element version update not possible. Please select a valid library element version. The blocks in OB1 are red, meaning that they have a problem. When I look at the instruction-set for datalogging, they are grey instead of black.
The version is V11.0 and I bought it just 2 weeks ago.
What library is the problem and how can I solve this ?
