LPACI counts accumulation only gets written to the change log every 5 minutes. If you update firmware and the restart completes before the next increment is written, the change log will reflect the last written count value, not the last actual increment.
BACnet Property | Short Name | BACnet Description | Notes |
|---|---|---|---|
object-type | ObjTyp | Object type | Value: 24 (pulse-converter) |
profile-name | PrfNam | Profile name | Value: 7-369-SBCv15.04 |
Prototype | BAObjTyp | Building automation profile | 369: (Pulse-Converter) |
IO-Extension | SubsysExtn | Subsystem | A writable enumerated proprietary property that specifies the type of I/O extension used. IO-Extension will always be AC-COUNT-IO. |
IOAddress | IOAddress | I/O address | A writable proprietary property that specifies the fieldbus (e.g., IO-0 for Onboard-I/O, IO-1 for TX-I/O) and IO module for this object. |
present-value | PrVal | Present value | A read-only* standard BACnet property that indicates the accumulated current value, in engineering units, of the input being measured. *The present-value property is writable when out-of-service is true. |
units | Un | Units | A writable standard BACnet enumerated property that indicates the measurement units of this object. |
scale-factor | CnvFac | Conversion factor | specifies the conversion factor for computing present-value. It represents the change in present-value resulting from changing the value of count by one. |
adjust-value | CorrVal | Correction value | may be used to adjust the present-value property (and thus the count property) by the amount written to adjust-value. |
count | Puc | Pulse count | A read-only standard BACnet property, of type Unsigned, that indicates the count of input pulses acquired from the physical input. |
update-time | UpdTi | Update time | A read-only standard BACnet property, of type BACnetDateTime, that indicates the date and time of the most recent change to the count property. |
count-change-time | CorrTi | Correction time | A read-only standard BACnet property, of type BACnetDateTime, that indicates the date and time of the most write to the adjust-value property. |
count-before-change | PucBfCor | Pulse count: Before corr. | A read-only standard BACnet property, of type Unsigned, that indicates the value of the count property just prior to the most recent change to the adjust-value property. |
cov-increment | Cov | Change of value, COV | specifies the amount of time in seconds between the periodic COV notifications performed by this object. |
cov-period | CovPrd | COV period | A writable enumerated proprietary property that specifies whether the optional intrinsic alarming extension is enabled for the object. |
Alarm-Extension | AlarmExtn | Event configuration | A writable enumerated proprietary property that specifies whether the optional intrinsic alarming extension is enabled for the object. |
