For You

The driver presents a system for building a MultiState value for device / module states.If a device is in an alarm state, the driver provides a number whose value reports the most&nbsp;important / serious of the possible active states. For example, if a device is in Alert and Alarm&nbsp;States simultaneously then the driver will report the Alarm state since it is considered a higher&nbsp;priority. &nbsp;If a device is a trouble state, then the driver provides a number whose value reports which&nbsp;trouble state is active (if only one state is active) or which reports that multiple states are active&nbsp;when more than one trouble is active
