Hi,
Is there a way to know if an optional input is used? I am programming an AOI for customers. There are 2 inputs A and B. Input B is optional. If it is not set it should be set to A internally. If it is set then then value set must be used.
Is there a way to know that B was set? It could be any value so there is no way to use a dummy default.
Thanks!
