Cannot open Step7 Library Functions

Hi guys!

On the LAD/STL/FBD window of Step 7 there are many folders (Bit Logic, Comparator, Converter,..., Word logic) and the folder "Libraries" (as you can see in the attached file).

I can access every folder, except "Libraries". Does anyone know why?

I want to access it because it has a lot of interesting SFBs and SFCs.

Thanks.

Alex

What happens when you click on the + to expand the folder?

Nothing!

It's like it is blocked.

What do you get if you attempt to open a library from simatic manager - here's what I get:

Yes! That's it! I did not know I had to load it! My fault...

Thanks!
