5.2.5.2 DATA LOGGER ASSOCIATED STATES
States associated to the data logger module (“Actual >Metering>Records Status>Records”) are shown on the table
below:
Table 5–13: DATA LOGGER STATES
OLDEST SAMPLE TIME:Date/time state type with 6 characters. This is the time that corresponds to the oldest sample.
This value will remain constant until the available memory capacity is exceeded. At that time, this value will change
according to the sampling rate (Data Logger Rate).
NEWEST SAMPLE TIME: Date/time state type with 6 characters. This is the time when the most recent sample was taken.
This value advanced in the time period defined by the sample rate setpoint.
If no channel has been selected, these setpoints remain with a static value.
DATA LOGGER CHANNELS:This state shows the number of Channels Selected by setpoint.
DATA LOGGER DAYS:This state shows the number of days that can be stored in the associated data file. It depends on
the Data Logger Rate setpoint, and on the number of channels selected.
5.2.5.3 DATA LOGGER FILES FORMAT AND RETRIEVAL
File Retrieval
Data logger files can be retrieved using EnerVista 650 Setup software, or the web server at “http:\\relay IP address”.
For obtaining data logger files using EnerVista 650 Setup software, the user must access “Actual>Records>Data
Logger”. The top of the window shows the date when the oldest sample was taken, and then the date when the newest
sample was taken.
This screen shows the measures stored for the different channels through the time.
Clicking on the “Download” button, all the information contained in the file can be read.
Clicking on the “Save” button, the data logger files (*.DAT, *.CFG) are retrieved in COMTRADE format, and saved by
default in folder “..\EnerVista 650 Setup\files\osc”, using “DLGxxx.DAT”, “DLGxxx.CFG” names, where xxx is the
corresponding record number. Data logger files can be retrieved only by Ethernet.
File Format
Data logger information is made of two text files: configuration file (datalogger.cfg), and data file (datalogger.dat).
