Chapter 6 Logging
Data Log
The data log stores user-selected values at a time interval that is defined in
parameter Data_Logging_Interval. The power monitor can store up to 60,000
records of up to 32 parameters. The default logging interval is 15 minutes.
Setup
The Data Log requires the following to be configured:
• Basic metering setup
• Date and Time setup
The first 22 parameters in the Data Log are configured by default, as listed in the
Logged Parameters table. Further configuration of the Data Log is not required if
the default selections satisfy your data logging needs.
To customize your Data Log, change the following set-up parameters, which
define the behavior of the Data Log. These parameters are found in the
Configuration.Data_Log
table on page 324.
Data_Logging_Interval
Data_Logging_Interval defines the logging interval in seconds. These values are
the selections:
0 = Disables data logging
-1 = synchronize log with demand period
1…3600 = User-selected data logging interval. Default is 900 (15 minutes)
Logging Mode
Logging Mode selects how records are saved.
0 = Fill and stop recording when log is full.
1 = Overwrite when log is full starting with the earliest record.
DataLog_Parameter_1
DataLog_Parameter_2
…
DataLog_Parameter_32
These parameters define the set of records that are maintained in the data log.
The Configuration.Data_Log web page includes the descriptions of the default
selections for each parameter, even if the selections have been changed from their
default value.
