Summary: |
This article describes how to manually initiate data set collection via certain triggers. |
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. |
Check the health of equipment. |
Click the Data Viewer ( |
|
Burst Mode |
Temporarily collect high resolution data on demand. |
Check the health of equipment using high resolution data. |
Click the Data Viewer ( |
When triggers occur at the same time a device is acquiring data, the device buffers the first data set collection trigger and begins another data set collection when the initial one ends. If two or more triggers occur during the data set collection, the device ignores the second and subsequent triggers. Consider the data set collection settings in the following example.

The following table describes how this behavior affects the contents of the data events the device creates and the way the data displays in on the Data Viewer page. Observe how the contents of the data events do not always match the value of the collection condition field that displays below the equipment name in the metadata pane when you select data on the Data Viewer page.
Use Force Trigger to acquire data from a single data group.
Complete the following steps to acquire data from channels associated with one equipment asset.
-
Click the Data Viewer (
) button. -
Expand the equipment asset for which you want to force trigger an acquisition, expand one of the sensors, and select one of the features to activate the Trend viewer chart.
-
In the Trend viewer chart, click the Action menu and select Force Trigger to perform an acquisition for that data group.
-
Wait several seconds for the acquisition to be complete and then confirm that data has been acquired by clicking the Refresh button and reviewing the Trend viewer chart.
-
Repeat the force acquisition several times to acquire multiple data sets.
Note
Before the data is available, devices must finish performing the acquisition and the InsightCM server must receive and store the data. The duration of a force-triggered acquisition is based on the file length of the Default Operating States for the equipment.
For a complete list of ways you can configure a device to perform acquisitions, refer to Methods for Initiating Device Acquisitions.
To perform an acquisition of all the device's channels, refer to Performing an Initial Acquisition for Continuous Devices.
High-resolution data is useful for troubleshooting equipment. To collect high-resolution data, you can use burst mode.
Complete the following steps to force trigger and view a periodic acquisition.
-
Click the Configuration pull-down (
) and select Devices. -
Double-click the device from which you want to collect high-resolution data.
-
On the Device Properties tab, select the Enable Burst Mode checkbox and configure the Burst Collection Settings. If you make changes in this step, update the device configuration on the Devices tab of the Device Configuration page.
-
Click the Action menu (
) on the Trend viewer toolbar and select Collect Burst Data Sets . -
Ensure the workspace is configured to load data from the appropriate time range.
-
If the Trend viewer already contains curves for the features or sensors of interest, click Refresh trend data (
) in the viewer toolbar. You may need to wait a few minutes to see high-resolution data in viewers, because devices must switch to burst mode, perform the high-resolution data acquisition, and send the data to the InsightCM server.
