Table 3 Data Logging Rules
Field Name Description
Log File Path Defines the directory in which the logged data folders and/or files are located.
The default logfile path is C:\YOURVIEW. If <logfile path> is empty, log files will
be stored in the LabVIEW default directory.
Duration Defines when a new log file will be created, based on time. The length of the
logged file can be set in this field. The default value is 24 hours. For example,
setting 1 creates a new file every hour.
NOTE: If the logging interval is set very short (for example, 1 min.), it is
recommended to set the file duration short as well (for example, 1 hour, or 1 day
at maximum).
Autodel Defines files older than the specified value (in hours) to be deleted
automatically. If autodel is set to zero (0) there is no auto deleting. The default
values is 0. When autodel is set = 0, the user must monitor the availability of
hard disk space for log files.
Min Intvl Defines the minimum interval for data logging. If Min Intvl is set to 1 minute, data
is not logged more often than once a minute even if the data value is updated
more often.
Log Items Define the data items to be logged.
YourVIEW Data
Socket Root URL Only the computer identification can be changed here. By default, the
identification is Localhost, which means the computer itself. Optionally, the
identification can be the name or TCP/IP address of the computer that produces
the data.
Source Source name for the data. This must match with the receiver settings.
Topic Topic name for the data. This must match with the receiver settings.
Name Item name for the data. This must match with the receiver settings.
Deadband Minimum required change of data value before it is logged. The default is
empty, meaning that all changes are logged. If one of the defined items
changes, all values will be logged.
FTP Recipients Optional FTP configuration
Email Attachments Optional E-mail configuration
Data will be logged as Comma Separated Values (CSV) ASCII
characters. The files can be read directly by other application
software, such as MS Excel. The header of each file specifies the
names and units of all the parameters in the file. Opening a log file
into MS Excel, each value is inserted in its own cell.
