Data Logging Setting
Pressing the "Settings for data logging" button opens the menu displayed below.
Figure 7.16
You can use the "Name of log file" field to set the file path and file names for logging data.
You can select "Data logging mode" to set the events that trigger automatic data logging. You
need to press the OK button at the end to save the setting.
Measured data can be recorded either on a continuous or event-driven basis. For event-driven
recording, the number of measured values to be recorded before and after the event is inde-
pendently defined via two parameters.
The following recording modes are available:
• Continuous
Data is continuously recorded and saved in the file. Data is sequentially recorded, but is
not necessarily consistent. Individual data may not be recorded depending on the sen-
sor's repeat measurement rate, data transmission rate, computer's capacity, and operat-
ing system tasks.
• Fixed time interval
Data is recorded at fixed time intervals. The time interval can be selected in fixed incre-
ments between 500 ms and 2 hours.
• Change of switching output state
Data is recorded in the event of a change of status of a sensor switching output. A further
parameter is used to define with what type of status change data should be recorded. You
can choose status changes to "Closed," "Open," or "In both directions." If the sensor has
more than one switching output, but only one should be used as a trigger for recording
data, the other parameters need to be set to "Ignore."
• Value changes exceed defined tolerances
Data recording is triggered by changes to data which exceed the specified tolerance lim-
its. The reference value is the distance value determined during the previous measure-
ment. The permissible tolerances can be specified either as an absolute value, i.e., in
mm, or as a percentage, relative to the previous measurement. If this tolerance limit is
exceeded from one measurement to the next, data recording is triggered.
