Using the Static Data Viewer

Version:
    Last Modified: November 29, 2021

    The Static Data Viewer is a web-based application that provides visual insights to live test data from structural test systems designed using the Static Structural Test Reference Architecture. Refer to the following sections for more information about using the Static Data Viewer, including tips and best practices.

    Static Data Viewer Overview

    The Static Data Viewer web application is accessible on any remote client that has access to the test system network. The Static Data Viewer provides a personalized view of live test data; log in with your credentials and make configurations that are automatically saved until the next time you log in. The Static Data Viewer is intended for multi-monitor viewing; open multiple browser tabs to view data from the same test.

    The Static Data Viewer has the following key features.

    • Filter and Select Channels—Filter and select the channels to view live data from the test.
    • Annotate Log Files—Record your observations as notes that are added to the test log file.
    • Configure Alarms—Configure alarms associated with a specific channel and user account to automatically annotate the log file when an alarm threshold is met.
    • View Live Test Data—View live test values and visualize the data in customizable graph views.

    Accessing the Static Data Viewer

    You can access the Static Data Viewer using the SystemLink URL provided by the admin that configured the test system web server.

    Tip  

    Bookmark the URL to quickly access the Static Data Viewer.

    If you are logging into the Static Data Viewer for the first time, you must complete the following steps to register your user account.
    1. Ensure that the client is either on the same network as the test system network or a VPN.
    2. Open a web browser and enter the SystemLink URL provided by the admin.

      Note  

      NI recommends using Google Chrome to open the Static Data Viewer.

    3. On the SystemLink login page, enter your Windows credentials associated with your organization.
    4. Notify the admin after you log in.
    5. Once the admin assigns the analyst role to your account, log in and begin using the Static Data Viewer.

    Static Data Viewer Environment

    The Static Data Viewer is hosted on the SystemLink Web Application.

    Home

    The Home page provides a full list of the channels that are configured in the test system. Use this page to select channels, configure alarm thresholds for specific channels, view alarms, and add notes to the log file. Refer to the following list for more information about each control on the Home page.

    • Channel Filter—Search for the specific channel(s) that you are interested in viewing. The search filter is case sensitive.
    • Channel List—Select the channel of interest from the Channel List. The total number of channels configured in the test system appear in the Total Channels field.
    • Data Table—View expanded channel information on channels you selected from the Channel List. Use the controls in the Data Table to configure and enable alarms and view the live data for multiple channels, as outlined in Configuring Alarms and Viewing Channel Data.

    Launch New Graph

    Open a graph in a separate browser tab to view the live values for specified channels in detail. Refer to Viewing Channel Data for more information.

    Alarms

    View alarm instances of a specific channel. If the alarm rules configured in the Data Table are met, an alarm is triggered and all alarm instances are displayed in the Alarms list until cleared. Clear the Alarm Enabled checkbox on a channel in the Data Table to disable the alarm rule for that channel. Refer to Configuring Alarms for more information about clearing and acknowledging alarms.

    Tip  

    Press <Ctrl> to select multiple alarms from Alarms to launch or delete at the same time.

    Note

    Enter comments in the Note field. The comments are added to the test log file and include your username and a timestamp.

    spd-note-tip
    Tip  

    The channel name is not automatically recorded in comments, so include the channel name in the comments as necessary.

    Saved Graphs

    The Saved Graphs page displays a list of all graphs that you launched from the Home page. Refer to the following list for more information about the controls on the Saved Graphs page.

    • Click Launch to open an existing graph in a new browser tab.
    • Click Delete to remove a graph.
    spd-note-tip
    Tip  

    Press <Ctrl> to select multiple graphs from Graphs to launch or delete at the same time.

    Saved Alarm Rules

    The Saved Alarm Rules page displays all Alarm Rules that you have configured on the Home page and whether the alarm is enabled or disabled. Click Delete to delete and clear alarm rules for a specified channel. When you delete an alarm rule, the alarm values that you configured for the specific channel in the Data Table on the Home page return to the default settings.

    Configuring Alarms

    Complete the following steps to configure alarms for channels.

    1. On the Home page of the Static Data Viewer, select the channel(s) from the Channel List.
    2. In the Data Table, specify a value for the HI Alarm (high) and/or LO Alarm (low) thresholds in the channel row for which you want to configure an alarm rule.
      spd-note-note
      Note  

      The default value for alarm rules is NaN, which indicates that an alarm rule does not exist for a channel regardless of the Hysteresis and Alarm Enabled fields.

    3. Specify the Hysteresis value for the alarm threshold. Use hysteresis to reduce recurrent alarms on channels with fluctuating live values. The same hysteresis value is applied to both the HI Alarm and LO Alarm rules.
      Alarm Example Behavior
      HI Alarm is set to 2 and Hysteresis is set to 1
      • The alarm becomes active when the channel value is greater than the HI Alarm threshold.
      • The alarm becomes inactive when the channel value passes below the HI Alarm threshold minus the Hysteresis value (2 - 1 = 1). The alarm becomes inactive (not cleared) when the channel value is 1 or lower.
      LO Alarm is set to 0 and Hysteresis is set to 0.5
      • The alarm becomes active when the channel value is less than the LO Alarm threshold.
      • The alarm becomes inactive when the channel value passes above the LO Alarm threshold plus the Hysteresis value (0 + 0.5 = 0.5). The alarm becomes inactive (not cleared) when the channel value is 0.5 or greater.
    4. Select the Alarm Enabled checkbox to initiate the alarm rule evaluation.
      spd-note-tip
      Tip  

      Click Disable All to batch disable the configured alarms. To clear configured alarm values and return the values to default, you must delete the alarm rule from the Saved Alarm Rules page.

    If an alarm threshold for a specific channel is met, the channel appears in the Alarms field. Click Clear to remove an alarm instance from the Alarms field. Refer to the following table for more information about alarm states.
    Table 1. Alarm States
    Alarm State Description
    Active (Red) The alarm is active and has not been acknowledged.
    Inactive (Clear) The alarm for the channel is inactive.
    Active (Yellow) The alarm has been acknowledged. Click Acknowledge Alarm to acknowledge the alarm instance.

    Viewing Channel Data

    Complete the following steps to view live channel data.

    1. On the Home page of the Static Data Viewer, view the Live Values of a specific channel in the Data Table.
    2. To view the channel data as a graph, check the Selected checkbox on a channel or multiple channels to group, then click Launch New Graph. The graph for the specified channel launches in a new browser tab and is automatically saved to the Saved Graphs page.
      Figure 2. Live Graph Example
    3. Use the Autoscale On/Off checkbox to change the size of the plot for your specific needs.
    4. Use the graph legend to change plot properties.
    5. View the list of Alarms and alarm states for the specific channels in the graph. You can acknowledge and clear alarms only from the Alarms list on the Home page.
    6. Add a Note to annotate the log file.
    7. Rename the graph title that appears above the Channel List. The graph name automatically updates in the Graph List on the Saved Graphs page.
    Closing the browser tab automatically saves the launched graphs. You can access the saved graphs from the Saved Graphs page when you log back into the Static Data Viewer.

    Error Reporting

    All errors for the Static Data Viewer are reported in your web browser console. Static Data Viewer errors contain an error code and source message.
