Parent Topic: Device Type Definitions
The DataStorage service that runs in NI InsightCM Server must know which types of features and spectral bands the device software calculates from sensor data. When NI InsightCM Server receives a data event from a device, it uses this information to determine which remaining features it should calculate itself. To provide the DataStorage service with this information, define a calculated features file.
|Note This definition is one part within the device type definition structure. In other words, when you export and import a device type definition, this definition is included.|
As the following example shows, calculated features files contain an array of strings, where each string is the value of the MetricType property in a feature definition.
