3.4 Connection types
The PC program WQL-Log works with two types of connection:
z
Work with database
(the logger and PC program do not communicate)
z Connected to logger
(the logger and PC program communicate)
Working with the
database
In this type of connection it is only possible to process the measurement data
stored in the database and to change the system settings.
Connected to the
logger
When the logger is logged on and connected to the WQL-Log PC program,
the program and the logger communicate with each other. The measurement
datasets present in the logger are read in to the database and are thus
available for processing.
You can parameterize the logger according to your requirements and set up
a logging job. When the logging job is started, the connection between the
logger and the WQL-Log PC program is cut. The cable connection between
the logger and PC does not have to be disconnected for this.
