Logic State
The Logic State screen is used to change the I/O relay to either normally
open or normally closed. The default state is open, which indicates that a
relay connected between the digital input pin and ground is normally open
and closes to trigger the digital input action. If nothing is connected to the
digital input pin, the state should be left at open to prevent the action from
being triggered.
