Logging Chapter 6
Energy Log
The energy log stores energy, demand, and scaled status input counter values at a
time interval defined in parameter Energy_Log_Interval. The power monitor
can store up to 90 days of energy log data. The default logging interval is 15
minutes.
Energy Log Results Files
The PowerMonitor 5000 unit stores the energy log in multiple comma-
separated-value (.csv) files, and selects a file duration based on the value of the
Energy_Log_Interval parameter.
In addition, the active energy log file is closed and a new file is created when any
of the following events occur:
• Initial powerup of the power monitor
• Subsequent powerup, if the active energy log file is older than the expected
duration
• If the Energy_Log_Interval parameter is changed
The Energy_Log_Mode parameter determines what happens when the log
contains 90 days of data:
• If set to 0 = Stop Logging, no new energy log files are created and no more
energy data is logged.
• If set to 1 = Delete oldest energy log file and create a new file, a new file is
created and energy logging continues uninterrupted. This is the default
setting.
File Names
Energy log file names have the following semantics:
EnergyLog_YYYYMMDD_hhmm_HH.csv
Where:
• YYYYMMDD_hhmm - the file creation date and time
• HH - UTC hour avoids duplication during daylight-saving time
