If 0 is entered, all programs are enabled in the first processing level for this channel. The
program number must be entered if only a particular program may be started in a channel in
the first processing level.
This may serve a practical purpose particularly when only a specific motion may be executed
in a channel, i.e. with respect to loaders, tool palleting, and the like.
