I have just checked the vi by change of its function to counter option. Now it seems ok as it is seen on the image. It is my careless of not changing the polymorphic vi function. Sorry 😞

That's an issue I reciently ran across myself! Those SILLY ULx IO Containers have FILTERS! Yup, just right click the silly purple I/O constant (or Control) and select "Filter Options>>" Those "Filters" only allow you to select the channel type that matches the poly instance of the ULx Create Task vi they are wired from when they are created. (Damned Annoying Right-o!)
