Sensor Classes
Sensors fall into the following classes:
Discrete:
 These are State Sensors. The reading they return contains two bytes where each bit can represent a
unique state.
 Up to 15 possible states (not 16 since bit15 from the returned reading is reserved)
 More than one state may be active simultaneously.
 Events are generated by a unique state. Thus, Event Messages do not return a bit field, just a single offset
value corresponding to a single event.
‘Digital’ Discrete:
 A digital sensor is not really a unique class, but a term commonly used to refer to special case of a discrete
sensor that only has two possible states.
Threshold:
 Threshold based.
 Changes event status on reading comparison to threshold values.
 Threshold enumerations may be considered a special case of the discrete sensor type.
OEM:

Special case of discrete where the meanings of the state’s (offsets) are OEM defined.
