AnalogInput (AI) object
This object is used for reading analog values from a programmable controller system to a BACnet device.
List of properties
The following shows the properties supported by AnalogInput objects.
Additionally, the availability of reading/writing data from/to a BACnet device is shown in the following table.
R: Read-only, W: Write-only, R/W: Read/Write
PropertyID Property Data type R/W Remarks
0 AckedTransitions BitString R
17 NotificationClass Unsigned R/W
22 CovIncrement REAL R/W
25 Deadband REAL R/W
28 Description CharacterString R/W
31 DeviceType CharacterString R/W
35 EventEnable BitString R/W
36 EventState Enumerated R
45 HighLimit REAL R/W
52 LimitEnable BitString R/W
59 LowLimit REAL R/W
65 MaxPresValue REAL R/W • Only ANSI/ASHRAE 2004,
IEIEJ-P-0003:2000 Addendum-a, and
IEIEJ-G-0006:2006 Addendum-a are
supported.
• This property informs other BACnet
devices about the maximum value of the
PresentValue property of an AnalogInput
object.
(Unlike the MaxPresValue property of an
Accumulator object, this property does
not indicate the range of a PresentValue
property.)
69 MinPresValue REAL R/W • Only ANSI/ASHRAE 2004,
IEIEJ-P-0003:2000 Addendum-a, and
IEIEJ-G-0006:2006 Addendum-a are
supported.
• This property informs other BACnet
devices about the minimum value of the
PresentValue property of an AnalogInput
object.
(Unlike the MaxPresValue property of an
Accumulator object, this property does
not indicate the range of a PresentValue
property.)
