Hi Community,
I was wondering if someone can give me a hint. I have a FB called 'FB_Filter'.
In FB_INIT I hand this FB two references over:

In the declaration part of the Function Block 'FB_Filter' I declare a a function called 'fbFlackvalve' that needs to get a reference to the Structure 'stValve':

How do I do this correctly? My attempt is not working...
Thanks for your help!

I just wanted to mention that the Function Block 'fbFleckvalve' will change the values int he passed on structure. So I need to pass on the reference.
