Trends are signals calculated from sensor raw data, e.g. RMS or ISO value of signals that come from data sources (e.g. TCP/IP). Trends do not have to be added manually as they are already included in the templates for aggregates, component groups, and components.

In the plant tree, different trends are created below an IEPE sensor depending on the template. For example, if an additional calculation is to be performed here, a new trend can be dragged from the library to the sensor. This enables you to make your work easier by using the templates, but you still have the flexibility to be able to perform custom calculations.

Note
	With the ibaCMU-S device, only 5 selective frequency characteristic values per sensor can be calculated.

Recommendation: Only create trends for sensors.

If you have added the trend using drag & drop, its parameters are set automatically.
