The Data Logging control allows you to configure and control host-side data logging operations from the NI VeriStand Workspace. With host-side logging, you can log channel data from a target to a file on the host computer while a system definition runs on the target. This control also enables you to manage past log files and perform post-processing actions with the data generated during a session.

To add the Data Logging control to your workspace, click the Workspace Controls palette, and then click the plus sign next to the Logging category. Select Logging Control and drag it to the alignment grid to add the control.

The Data Logging control contains the following components:
  • State—Displays the current state of the Data Logging control, including:
    • Offline—Indicates that the system definition is not deployed and the Data Logging control is inactive.
    • Idle—Indicates that the system definition is deployed and the Data Logging control can run.
    • Log Session Started (No Active Session Log)—Indicates the Data Logging control is running but not recording data. This status displays if you do not select any channels to log.
    • Starting Log Session—Indicates the Data Logging control is beginning the log session.
    • Waiting on Trigger—Indicates the Data Logging control is waiting on a start trigger to start the log session.
    • Triggered—Indicates the Data Logging control is logging.
