Trend_Log Properties
Used
R/W Units Additional information
Stop_Time W Date/Time Sets the Date/Time when data Logging will STOP (if still running).
Stop_Time will be ignored if “”wildcard”” values are used in any of the fields.
Log_Device_Object_
Property
W BACnetDeviceObjectProptertyReference Set (point) this to the Present_Value of any of objects AI1 through AI49
to establish which parameter to log. Default values are:
TL1 = Real Energy Consumption (Array of AI1 Present_Value)
TL2 = Reactive Energy Consumption (Array of AI27 Present_Value)
TL3 = Total Real Power Present Demand (Array of AI34 Present_Value)
Log_Interval W 0.01 seconds Logging period in hundredths of a second.
Default is 90000 (15 minute intervals); minimum value is 1000 (10 seconds). This property can
also be set to Zero, which will change all three Trend_Logs and the Demand calculation to a
manual mode (sometimes referred to as “Sync to Comms”. In manual mode, the demand interval
is updated and another record is logged upon a manual command, which is issued by writing the
value 21211 to the Present_Value of object AV1.
Stop_When_Full W Binary Set this to TRUE to stop logging when the buffer is full (single-shot mode) or FALSE to continue
when full (wrap & overwtrite oldest data entries).
Buffer_Size R 5760 Length of Log Data buffer (# of records).
Log_Buffer R List of BACnetLongRecord Contains the data values logged, with timestamps
Record_Count W Unsigned 32-bit integer This is an integer count of how many records logged since the Trend_Log objects were last reset.
Writing a Zero to this property resets the logs of all three objects. This value defaults to Zero, but,
by default, logging will start automatically at 15 minute intervals.
Total_Record_Count R Unsigned 32-bit integer This is an integer count of how many records logged since the Trend_Log objects were created (the
factory state of the meter). This count is unaffected by resetting the Record Count or by power
failures.
Event_State R Binary
