33.2. DIRECTORY STRUCTURE
The unit will record data in either an USB-Flash memory or a micro-SD flash memory card. The record
structure is the same in both cases.
SITE-ID
Previous years
The unit will record data in a directory named with the first 11 characters of its site-id parameter. In order
to avoid confusion between records, it is highly recommended to configure the site-id parameter
accordingly to the genset installation place. Thus the same memory module may be used for recording in
different controllers,
Inside the <SITE-ID> directory, the unit will open a separate directory for each year of recording. The
directory will be simply named by the year, like 2012, 2013 etc...
Inside the year directory, the controller will record data in a different file for each day of recording. The
record file will be named YYYYMMDD like "20120331" representing March '31, 2012. Thus alphabetical
listing will produce a sorted list by date of recording.
The recorded file is of CSV (comma separated values) type. This is a text file which can be directly
opened with Microsoft Excel program without any loss of information. It can be also opened with any text
editor (like Notepad program).
Inside the file, each record consists of a line including a large set of measured parameters. The recorded
parameters list is not adjustable. The controller records all practically necessary parameters.
33.3. UNDERSTANDING THE CSV FORMAT
The ".csv" file is basically a text file format. Thanks to this, it can be opened by any text editor in any
operating system.
When opened with the Microsoft Excel program, the values will appear in tabulated form, enabling
application of formulas, graphs and other features of Excel program.
