To stop collecting trend data for an object, the trend definition must be removed from the database. This procedure removes a trend definition for an online trended object and archives data that was already collected.

Note
When data points are integrated, any trend definitions already in the device are identified as offline trended objects. If an offline trended object is removed from a device, repeat the data point integration process to also remove the offline trended object from Desigo Control Point. An error occurs if you try to use an offline trended object that has been removed from a device.
