Description of
Present_Value Property
SENSOR AI 1 Gas concentration of sensor.
LIFETIME AI 2 Remaining hours until sensor replacement.
RUNTIME AI 3 Hours of runtime for sensor.
Device_Instance AV 1 Alternative way to change object_identifier property of device. Fractional
values are truncated.
Identifier_Value_Prefix AV 2 Initially 133, this is the value is prepended to the MAC address in the device
object identifier value.
High_Set-point AV 3 High set-point value. Originally sensor high set-point.
High_Hysteresis AV 4 High hysteresis value. Originally sensor high set-point hysteresis.
Low_Set-point AV 5 Low set-point value. Originally sensor low set-point.
Low_Hysteresis AV 6 Low hysteresis value. Originally sensor low set-point hysteresis.
High_Set_point_Exceeded BI 1 Becomes ACTIVE when AI 1 ≥ AV 3; becomes INACTIVE when
AI 1 ≤ (AV 3 - AV 4).
Low_Set_point_Exceeded BI 2 Becomes ACTIVE when AI 1 ≥ AV 5; becomes INACTIVE when
AI 1 ≤ (AV 5 - AV 6).
Device_Object_Reset BV 1 Always reads INACTIVE. Write ACTIVE to reset the Device Objects Object_
Name and Object_Identifier to their defaults.
High_Relay_Override BV 2 ACTIVE means BV 3 controls relay, otherwise BI 1 controls the relay.
High_Relay_Level BV 3 When BV 2 is ACTIVE, an ACTIVE BV 3 behaves like the set-point has been
exceeded.
Low_Relay_Override BV 4 ACTIVE means BV 5 controls relay, otherwise BI 2 controls the relay.
Low_Relay_Level BV 5 When BV 4 is ACTIVE, an ACTIVE BV 5 behaves like the set-point has been
exceeded.
Lock_Settings BV 6 When BV 6 is ACTIVE, DIP switches are disabled, and register values control
the settings. When BV 6 is INACTIVE, the DIP switches control.
