Setting Thresholds

Thresholds are used to indicate whether evaluated data is located inside or outside some given range or area. Thresholds are visualized with traffic lights. The Configuration Creator supports constant thresholds for which the calculation is based on the corresponding signal only. You must define four constant values for min, low, high, and max. For more information about the ranges, see Traffic Lights.

  Depending on the chart type, you can define the following settings for one or more axes.

• Each of these values can be enabled or disabled separately. Select the Enabled? checkbox accordingly.

• Optionally, select the tolerance type and enter a value.

• Select the evaluation behavior.
