IO/Inputs/[DIN]/Latching Registry Key
Enable this Registry key when the associated input is to be latched. When
enabled, the input will be considered to remain in the state defined by the
LatchState setting after the voltage applied to the external input is
changed. If the LatchTime is set to 0 seconds the User must manually reset
the input. This can be done through the WebUI or other application.
