NI Monitoring Devices continuously monitor data from equipment. However, these devices collect and log data only when initiated by one of several types of triggers. Use one of the following triggers to collect and log data.
Either the NI InsightCM Server or software on the devices automatically initiates a data set collection when the following triggers fire.
|Type||Description||Use Case||Where to Configure|
|Time interval||Collect a data set at specific times of day or intervals of time.||Ensure that trends are complete enough to provide a useful display of machine conditions.||Operating States tab on the Asset Configuration page|
|Delta EU||Collect a data set when a feature or spectral band value changes by a specified amount.||Ensure data is collected at the time that a rapid change in measurements occurs.|
|Enter Condition||Collect a data set when the enter condition for an operating state is met.||View the measurements from the time that equipment changed its status.|
|Exit Condition||Collect a data set when the exit condition for the active operating state is met.||View the measurements from the time that equipment changed its status.|
|Alarm set||Collect a data set whenever an alarm condition is met.||Access data from the time an alarm condition occurred.||Alarms page|
|Alarm clears||Collect a data set whenever an alarm clears.||Access data from the time an alarm condition ended.|
|Burst mode||Collect high-resolution data sets at specific times of day or intervals of time.||Troubleshoot equipment with data that may indicate an issue.||Device Properties tab on the Device Configuration page|
Users manually initiate data set collections via the following triggers.
|Type||Description||Use Case||Where to Initiate|
|Force Trigger||Collect a data set on demand.||See or check the health of equipment.||On the Devices tab in the NI InsightCM web application, navigate to the Force Trigger option in the Action menu.|
|Burst Mode||Temporarily collect high resolution data on demand.||See or check the health of equipment using high resolution data.||On the Data Viewer page in the NI InsightCM web application, navigate to the Collect Burst Data Sets option in the Action menu .|
|Test Panel||Temporarily display live data in the NI InsightCM web application.||Quickly see or check the health of equipment without collecting and storing a data set.||Test Panel page|
The variety of triggers available in NI InsightCM Server means that devices can perform collections more frequently than the standard time-based intervals. Consider a device whose configuration includes the following settings:
|Total collection duration||1 time unit|
|Timed-based trigger||Every 7 time units|
|Delta EU trigger level||3 engineering units|
The following illustration shows an example of how the device might perform collections over a period of time.
|1||Begin Collection A (Delta EU trigger)||7||Begin Collection D (Alarm cleared)|
|2||End collection||8||End collection|
|3||Begin Collection B (Periodic collection)||9||Begin Collection E (Periodic collection)|
|4||End collection||10||End collection|
|5||Begin Collection C (Alarm set)||11||Begin Collection F (Delta EU trigger)|
|6||End collection||12||End collection|
The following table lists the values logged and displayed on the Data Viewer page during each collection in the previous graph.

During multi-second collections, devices always log only the final second of static-sensor data. For example, in the previous graph, if each collection spans 6 seconds, the only value logged is the value collected during the final second. These are the values at the shaded callout circles. However, for waveforms in a multi-second collection, devices calculate and log values from the entire duration of the collection.
