Data Point Library

The Data Point Library provides a collection of data points with default values for data point properties.

Data point properties are similar to "paragraph formats" in word processing applications: You do not want to format each paragraph individually. Instead you want to define a set of default formats and apply them to your paragraphs in your document.

The Data Point Library provides the same functionality for data points: It provides a number of default data point templates that can be applied easily to your data points from different devices.

How does the Cockpit application use the data point library? To find the default visualization for a data point like color or label, Cockpit searches the data point library and tries to find a matching entry. An entry is considered as "matching", if the values for fragment and series in the data point library match those of the measurement. If a matching entry is found, the corresponding data point properties are used for a default visualization.

Additionally, the properties of the Data Point Library are used by threshold business rules: The red and yellow values configured in the Data Point Library are used by the threshold rules to raise alarms.

To open the Data Point Library, click "Data Point Library" in the Configuration menu of the navigator.

A list of available data points will be opened. For each data point, the following information is provided in the list:

  • Color and label for the data point
  • Fragment name and series
  • Measurement unit
