Thanks. So it would seem it is not possible but Codesys seems happy enough with it to just be called without assigning to a variable as long as you're not assigning anything to the output in the function. Still need to define the type of output but no need to do anything more than that.
Here is what I'm working on for those that might be interested. https://www.youtube.com/channel/UCepKsWePdtKjsud7cqjbB9A I'm hoping this is the right place to just post general questions as I'm trying to figure out how to program more complex things in Codesys. First thing is I'm trying to figure out how to work with Functions using Pointers. I think I've got it mostly figured out but the part that doesn't make sense is how the function needs to return something. Is it possible to not return anything...
