is it possible in Codesys 2.3 to have a function return value VOID?
I need it to create some function that return more values (defined maybe as IN_OUT for example)

I know, thanks, but a FB need to be declared also as instance data.. so for sure it'll need more memory usage than a FC.
This is my habit coming from Step7 IDE.. I used few time FB, almost always FC.And when need flags data as counters or latched memory I add some INOUT parameters in my FC

no a function can not have more outputs. only one.
but a function block can and that should be used,

hi, i think you can return a struct with all data you need!
