Viewers with sensor data |
The Data Viewer page has two operating modes designed for viewing specific types of data:
-
Periodic Data—Data trends over a customizable time range.
-
Stream Data—Live or historian data acquired continuously during an operating state, such as run-up or coast-down. The time range for which you can access data is restricted to the duration of the operating state.
To provide a starting point for your analysis tasks, both modes have a default layout of viewers and a customized toolbar for working in that mode.
To load stream data or subscribe to a stream, view the Data Viewer page in Stream Data mode.
When the Data Viewer page is in Stream Data mode, switch to Periodic Data mode by clicking the Switch to periodic view button on the Data Viewer page toolbar.
Viewing auto-refresh can be configured by clicking on the auto-refresh icon (). Auto-refresh options are Off, 30 seconds, 1 minute, 5 minutes, and 10 minutes.
Multiple cursors allow viewing waveform data from two or more locations on the trend value timeline (e.g., 10 a.m. and 1:00 p.m. on a particular day or different days).
The following steps describe the actions to create multiple cursors:
-
The first cursor can be created by double clicking in the trend viewer chart or by clicking on the cursor selector in the trend viewer and selecting Add Cursor.
Note: Clicking on the double vertical lines will show or hide the cursor.
-
Within the cursor menu click its Action menu and select Add Cursor. Repeat step to create additional cursors.
-
Each cursor is listed with a timestamp and description. The active cursor is indicated by a solid red circle. Double clicking in the trend viewer will move the active cursor. Click on any other non-solid red circle to make that cursor the active cursor.
Cutsforth monitoring devices, such as Condition Monitoring Systems (CMS), are designed to detect when a piece of equipment enters a particular state of behavior, and then collect and group a series of data files until the equipment reaches a steady state. For example, a device detects that a turbine begins a run-up when the speed measured by a tachometer increases to above 200 RPM; it then enters an operating state in which it collects and groups files. When devices group files in this way, the resulting files are referred to as a stream. The Data Viewer page provides several features for displaying data that has been acquired as part of a stream.
A stream is a single entity that combines many measurements from one device for the purpose of visualizing the data as a group. This is useful because by interacting with a single stream, you can quickly view all data the device acquired when the equipment was experiencing the behavior of interest. In the case of run-ups and coast-downs, where speed measurements cause a data group to enter a stream-enabled operating state, a stream contains the trend of speed measurements throughout the run-up or coast-down, as well as data from each sensor in the data group.
The following steps describe the actions that occur during a stream-enabled operating state to produce a stream:
-
A device detects when a speed condition is met and starts collecting files. For example, a device detects a run-up when the speed increases to above 200 RPM; it then starts a cycle of collecting ten seconds of data, waiting for fifteen seconds, and then repeating.
-
InsightCM Server receives data from the device and makes the data available for viewing on the Data Viewer page.
Note
On the Data Viewer page, you can subscribe to the stream to update viewers with live data. See Watching a Live Stream.
-
The device detects the stop condition that indicates the equipment reached a steady state, and then stops performing stream acquisitions.
-
On the Data Viewer page, you can load the stream of data that the server created.
The following illustration shows the role of each component.
The following workspace shows the Data Viewer page with a run-up stream loaded. Notice the following characteristics:
-
The Trend Viewer contains a single trend of speed values from the tachometer whose measurements indicate a run-up and trigger stream acquisitions.
-
The Trend Viewer time axis is restricted to the duration of the run-up. In other words, you cannot adjust the time range to show other historical measurements that occurred before or after the run-up.
-
Other viewers contain measurements from several different sensors.
-
If you place a cursor in the Trend Viewer and move it with the arrow keys, the data in the other viewers will update to match the timestamp of the Trend Viewer.
Behavior when Devices Monitor Multiple Pieces of Equipment or Multiple Devices Monitor the Same Equipment
Streams consist of all the data that sensors on a specific data group acquire. 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 on multiple pieces of equipment whose data you want to acquire according to different parameters.
If a device monitors two pieces of equipment, each with unique operating behaviors, ensure the pieces of equipment belong to separate data groups. Otherwise, if the data group experiences an enter condition that is relevant for only one piece of equipment, the device includes data from the second piece of equipment as part of the stream.
Data streams are similar to periodic acquisitions in the following ways.
Streams differ from periodic acquisitions in the following ways:
-
Users can configure a device to continuously collect files at intervals of only a few minutes or delta EUs when it enters a stream-enabled operating state. However, periodic acquisitions might occur much less frequently, such as only when a time interval elapses or a delta EU or alarm condition evaluates true.
-
Separate aging rules apply to stream and periodic data files.
View streams from all equipment or from one equipment as streams begin.
When a stream-enabled operating state is in progress, data viewers can display live trends and measurements as devices acquire data from equipment. Choose one of the following ways to begin viewing a stream.
-
Click the Data Viewer (

Enable compensation for slow-roll data when viewing your data.
Vector Compensation - When you configure sensors, InsightCM provides 1x Magnitude Reference and 1x Phase Reference properties that specify the magnitude and phase values when the shaft is at slow-roll speed. The Data Viewer page uses these properties to compensate for slow-roll in Bode and Polar viewers. If the configured reference values are incorrect, or you want to temporarily override them with different values, you can compute and apply new slow-roll references within the Data Viewer page. Complete the following steps to change the configured magnitude and phase references.
-
Click the Data Viewer (
-
Click the Layout (
) button on one of the viewers, navigate to Chart type > Vibration, and select Bode or Polar.

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.
|
Setting |
Value |
|---|---|
|
File Length |
10 Seconds |
|
Delta EU Trigger Level |
3 Engineering Units |
|
Alarm Rule |
Above 75 Degrees |
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 (
-
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 (
-
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.
Trend baselines determine the values that InsightCM uses to create trend alarms.
Complete the following steps to create a trend baseline for an asset.
-
Click the Navigation menu (
-
In the Trend Baselines dialog box, select the asset for which you want to create a baseline.
-
Click Add.
-
In the Create Trend Baselines dialog box, select an operating state.
-
Click OK.
When you view data, the cursor appears as a vertical red line that intersects the plot at a point where a data set was acquired, as shown in the image below.
Complete the following steps to move the cursor to a data set of interest on a trend plot.
-
Click the Data Viewer (
-
Click the Annotate Data Sets button on the Trend viewer toolbar to show all points where data was acquired.
-
Double-click the data set you want to inspect. You can also press the <Left-arrow> or <Right-arrow> keys to move the cursor from data set to data set. Although the Trend viewer calculates feature trend points even when no data is acquired, you can only place the cursor at points where there are data sets.
When you place the cursor on a data set in the Trend viewer, the other viewers automatically update with sensor data from the selected data set.
Analyze historical periodic data by loading a feature in the Trend viewer and then loading the data set in a waveform, spectrum, or other sensor data viewer.
The Trend viewer serves as a master viewer for the workspace because you load and browse feature trends to see sensor data.
Complete the following steps to load a trend and view the sensor data that comprise the trend:
-
Click the Data Viewer (
-
Select an asset feature to load its data in the Trend viewer. To load data from multiple features in the Trend viewer, <Ctrl-click> to select multiple features or <Shift-click> to select a range of features.
-
Click the Annotate Data Sets button on the Trend viewer toolbar to flag trend points that have data sets associated with them.
-
Double-click a point on the trend plot that has a data set. The sensor data viewers update corresponding to the data set for that trend value. If a viewer remains empty, it might not support the sensor whose features you loaded. Refer to the Unsupported Sensors for Sensor Data Viewers section below for more information.
The following workspace shows the result of selecting a feature from the asset tree. Notice the trend plot includes a point for each acquisition over a period of several days. The Waveform and Spectrum viewers display the sensor data acquired at the position of the cursor within the Trend viewer.
Unsupported Sensors for Sensor Data Viewers
Some sensor data viewers display data only when the Trend viewer contains features from certain sensors. Consider the following examples:
-
Waveform and Spectrum viewers support sensors that acquire waveforms rather than single-point measurements such as temperature.
-
The Orbit viewer supports only pairs of displacement sensors connected to orthogonal probes that have the same tachometer reference.
In this situation, sensor data viewers remain empty until you load features from supported sensors in the Trend viewer. Refer to Available Viewers and Options for Configuring Them for sensor support considerations for each viewer.
Conditions Where Data is Unavailable
Although you have access to all data stored on the InsightCM Server, the following factors can affect your ability to load the data:
-
In Periodic Data mode, the Trend viewer has a time-range property that controls the length of trends you load. Even if more data is available on the InsightCM Server, the Trend viewer displays only data from the configured time range.
-
If administrators set data-aging rules, the server automatically deletes historical data when a set amount of time passes. Aging is useful for conserving space on the server. However, to prevent InsightCM from deleting certain trend values and sensor data due to its age, you can mark the data to be retained.
-
In Stream Data mode, you can only load trends from equipment that is part of a stream. Also, the time range in viewers is restricted to the duration of the stream you load, so you cannot see additional data even from equipment that is part of the stream.
-
Because of screen resolution constraints, the viewer may not be able to display every point in a data set. As a result, some viewers downsample data by default so that viewers can load data faster and conserve memory. This means that the viewer displays only the data points necessary to generate an accurate plot.
When you zoom within a viewer with downsampling enabled, InsightCM queries the server for new data to display. Therefore, the viewer resolution remains the same even though the zoomed view displays fewer points than the original view.
To disable downsampling, complete the following:
Compare measurements from multiple points in time or from multiple pieces of equipment by creating data event references that you can show in a chart later.
Complete the following steps to create a data event reference:
-
Click the Data Viewer (
-
Select an asset.
-
Select a trend point to create a data event reference for the Trend viewer.
-
Click the Action menu (
-
In the Choose Reference Type dialog box, choosing creates one of the types of references given below. These references can be used to mark specific data events from an asset and show that data alongside other data from the same asset.
-
Baseline—The default data reference.
-
Slow-Roll—The reference InsightCM uses to calculate slow-roll compensation if you enable slow-roll compensation on the Order Waveform or Spectrum viewer.
-
Temporary—A data reference that disappears after 24 hours.
-
Other—A reference you create for any other reason.
-
-
Click OK.
-
On the Data Viewer page, click Select a Data Event Reference and select the data event reference you created.
-
In any viewer on the Data Viewer page, click Show Reference to display the reference you selected.
