When linking an input-type slot of a writable point or kitControl object, the value received at the input is processed (evaluated)
by that point or object, if it is valid.
NOTE: A valid input is one with none of the following status flags set:
- down
- fault
- disabled
- null
- stale
If any of the above status bits are set at an input, that input value is not used.
- If a kitControl object with a single input, by default that object uses the last known valid received (at least until the
input becomes valid again).
- If a kitControl object with a multiple inputs, only the valid inputs are evaluated.
- If a writable point, the priority scan continues.
