3.4.2 Setting a discrete input’s operational mode
A discrete input has three operational modes: Auto, On, and Off.
Setting the discrete input to Off means that it will interpret all
incoming signals as OFF, despite the true nature of the signal.
Setting the discrete input to Auto means that it will analyze the
incoming signal to determine whether it is ON or OFF.
Setting the discrete input to On means that it will interpret all
incoming signals as ON, despite the true nature of the signal.
