• A total of 1000 measured values can be stored
• 4 logging channels
• Adjustable logging interval for data logging
• Display of the measured value trend for each logging channel in the form of a chart:

Fig 60. Chart of a measured value trend
• x-axis: depending on the number of channels selected displays 250 to 1000 measured values of a
process variable.
• y-axis: displays the approximate measured value span and constantly adapts this to the ongoing
measurement.
If the length of the logging interval or the assignment of the process variables to the channels is changed, the
content of the data logging is deleted.
