When users configure a device in the NI InsightCM web application, they assign the device channels to one or more data groups. A data group is a set of channels mapped to sensors that monitor the same piece of equipment. Data groups are useful in situations where a single device connects to sensors whose data you want to acquire, analyze, and log according to different parameters. Consider the following simplified example where one device monitors two pieces of equipment.
Assigning the channels monitoring each piece of equipment to different data groups allows you to configure unique behavior for each group of channels even though they belong to the same device. The following example shows how defining separate data groups allows users to configure behavior that is appropriate for each piece of equipment.
|Data Group||Channels||Speed Reference||Operating States||Data Set Collection Settings|
||Fixed speed: 3600 RPM||Default||
Establishing separate data groups also ensures that if a particular event, such as a run-up by the turbine, triggers the device to collect data as part of a stream, the stream contains data from only the turbine instead of from all channels, including those not affected by the run-up.
