Data Copy (4)
NOTE: the NI400 should be in “Stop” or “Config” state before using this function.
If you press Enter key in correspondence to the menu entry Data Copy (4), the NI400 cop-
ies all logs on USB Drive. Flashing letter d is displayed during files copy. At the end of the
copy, flashing number . (dot) will be shown to indicate to the user to remove USB flash
drive and, after that, letter A if copy was successful. If an error occurred, the system will go
to error state and an error code will be shown.
WARNING: it is not possible to connect USB hard drives to this port because these devices
need too much current to work correctly. In addition, it is not possible to connect to this
port any device different from flash drive (i.e. Bluetooth key, internet key, ect.)
At copy process completed, a 15 sec timeout starts. After that, the NI400 will come back
to main menu and will start the timeout display (it can be set up from the web). At timeout
display expiration, the display will turn off.
While the menu shows the copy state (error code or OK), Select key causes the display
back to main menu (and timeout reset display).
While the menu shows the copy result, Enter key causes the timeout reset from 15 sec.
Export File (Measure and Measure Log) Format
With the NI400 you can download data (measures, events log, alarms logs) using:
an USB flash drive
a PC (through web interface)
a FTP or e-mail
USB flash Drive
After the copy using a USB flash drive, a folder with the following format will be automati-
cally created:
<NI400name>Log
Within the folder there will be the following four “.csv” files:
ALog_dd_mm_yy.csv : in this file there are all the alarms detected from the NI400;
ELog_dd_mm_yy.csv : in this file the events recorded from the NI400 are saved;
MLog_dd_mm_yy.csv : in this file the measures in log format are saved. There are also
other information such as any alarm for the sensors, the measurements unit, the vibrating
wire measurements parameters, etc.;
MLog_dd_mm_yy.Column.csv : in this file the measures ordered in columns are saved. This
kind of display is suited for data management with spreadsheet.
In the file name dd is the day, mm is the month and yy is the year.
PC
When you download data directly from the NI400 web pages (there is a specific field for
each data file) you can choose the destination folder on your PC and the file name if your
Internet browser is well configured.
FTP or e-mail
If you set the NI400 to transmit the .csv reading file (only the one ordered in columns) by
e-mail or by FTP, the name of the file is the following:
mLog_dd_mm_yy__hh_mm.csv
In the file name hh is the hour, mm is the minute.
