File Retrieval
Data logger files can be retrieved using the EnerVista 650 Setup software, or the web server at "http:\\relay IP address".
For obtaining the data logger files using the 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 measurements 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 the 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).
