Thank you Martin!
On my screen the + is to the far right, and it only works on HMI Projects

Hello there,
I have just started to migrate to ST - these big diagrams gets messy in the long run ;)
Now I'm just trying to call a function block from st.


But i always get 'no value'.

My question is, how do I call ph_control_hourly and get the value of the variable 'out'?
Thanks a lot
