Untied/ unallocated logic gate input?
Hi All,
What happens when one configures a logic gate with nothing configured to one of the source inputs?
Reason for this coming up, is I have a cascade of logic gates for the use of lighting a DFP panel button (to alert me if there's any of a variety of outside lights switched on).
However I've decomm'ed one of the lights (temporarily, possibly permanently), but don't want to redo all the Logic gates just yet.

Thanks in advance,

I believe that the default is always that an unconnected input effectively sits at '0' (False).

Suggest create a spare Test On-Off Source and connect it to that input. Then you can set it to 1 or 0 as required to satisfy your logic for the time being.
