WebDAQ Data Logger window

Use the Data Logger window to create a schedule of jobs, run the schedule, and view live data on the Dashboard.

The Data Logger Schedule tab displays by default when you open the Data Logger. The image below shows a typical window for a Schedule with two jobs. The right pane summarizes the options configured for the selected Schedule or job.

The Data Logger window includes a Run All button, Schedule tab, and Dashboard tab.

Schedule

The Schedule tab displays the current status, the job list, a configuration summary, and tool bar for performing job and schedule-related tasks. Tap next to a job name to run the job, or to stop the job. Note that users cannot run an individual job that has dependencies on other jobs, such as a "Jump to Job" alarm. Job configuration options are discussed in the Job Editor topic.

Schedule Tab Toolbar
New Job	Opens the Job Editor to create a new job configuration.
Edit	When a job is selected, opens the Job Editor populated with settings for the selected job. When the schedule is selected, opens the Schedule Settings dialog box to configure schedule options.
Duplicate Job	Creates a copy of the selected job in the job list using the "Job#" job name.
Delete	When a job is selected, deletes the job from the job list. Save the job first if you plan to use it again. When the schedule is selected, deletes the schedule and restores schedule settings to default values. A dialog prompts for confirmation to complete this action.
Move Down	Moves the job down in the job list. Jobs are run sequentially according to the order of this list.
Move Up	Moves the job up in the job list.
Config Files	Displays options to save a job or schedule to a file, import an existing job file to the job list, or import a schedule file to replace the job list. Both job and schedule configuration files are saved with the extension ".json". Users can download saved jobs and schedules to a local drive and upload either to this or another device; refer to the Data Files* window Files tab for more information. Job options: Save To File: Opens the Save Job As dialog box. Job settings are saved as a configuration (.json) file in the specified WebDAQ storage location. Import From File: Opens the Import Job* dialog box to select the job file to import. Schedule options: Save To File: Opens the Save Schedule As dialog box. The schedule settings, job list, and the Job settings for all jobs listed in the schedule are saved in a configuration (.json) file in the specified WebDAQ storage location. Import From File: This operation removes all jobs in the current schedule; a dialog box displays for confirmation. When confirmed, opens the Import Schedule* dialog box for users to select the *.json schedule file to import. The selected schedule and all of its associated jobs are imported.
Schedule Settings	Opens the Schedule Settings dialog box to configure when to start the schedule, how often to repeat the schedule, and whether to stop the schedule and cancel any remaining jobs if an error condition is detected.

Dashboard

The Dashboard displays thermocouple (or voltage) data on scalar and strip chart displays. The alarm status is also displayed, when configured. Each display can be hidden (minimized) by the user.

The Dashboard displays time domain data on a strip chart, and frequency domain data on an FFT display. The alarm status is also displayed, when configured. Each display can be hidden (minimized) by the user.
When viewing FFT data, the maximum peak values are optionally displayed on the data plot and in the legend below the plot. The FFT size for display purposes is calculated based on the sample rate to achieve a resolution bandwidth of approximately 1 Hz.

The Dashboard displays measurement data on scalar and strip chart displays. The alarm status is also displayed, when configured. Each display can be hidden (minimized) by the user.

Note: the Dashboard cannot display live data when logging directly to an FTP server. For this type of operation the Dashboard is disabled during logging, and updates with data when the job completes.

Dashboard tab

Users can minimize individual scalar and alarm displays, show/hide channels on the strip chart, and view/reset alarms on the Dashboard.

Users can minimize individual displays, show/hide channels on the strip chart and FFT displays, and view/reset alarms on the Dashboard.

Tap the color swatch on a strip chart, scalar, or alarm display to minimize the display for that channel.
Tap the color swatch on a strip chart, alarm, or FFT display to toggle the channel on the display on and off.
Tap on an active alarm icon and select Reset to manually reset an alarm (not available if the reset configuration is configured for automatic). To reset an alarm condition automatically if the condition is resolved, refer to the options on the Job Editor Alarms tab.
Select the gear icon on the Strip Chart display to open the Strip Chart Settings dialog box. Use this dialog box to enable Y-axis scaling and to set the display mode of X-axis data — select from Samples (the number of data samples acquired), Relative Time (the length of time since the acquisition began), or Absolute Time (the time of day when samples are acquired).

Changing display settings on the dashboard
All changes made to the dashboard display of a job prior to the acquisition are retained in the job description, and will be applied to all future acquisitions of that job. Changes made during the acquisition are not retained in the job description, and will not be applied to future acquisitions of that job.

When viewing FFT data, select the gear icon on the FFT display to open the FFT Plot Settings dialog box. This dialog provides options to set the window type per-channel, to show or hide the peak frequency on the FFT plot, and to set the spectrum type. Set the X-Axis range values to view data in a specific frequency band.

Run All

Tap to execute the Schedule and run each job in the job list.

The following events occur when the Schedule is run:

The blue Run All button changes to a red Abort button.
The schedule start condition is evaluated, and the first job starts when this condition is met.
Each job in the job list is run in sequential order.
Data displays on the Dashboard as it is acquired.
The current job status displays on the Schedule and Dashboard tabs; examples are Running, Stopped, Completed, Running (waiting for a trigger), or Queued. The current system status displays in the lower left corner; examples are Idle or the name of the currently running job.

Stopping or canceling a job

To stop a job configured for manual stop, or to cancel a job configured for any other stop type, but to continue running remaining scheduled jobs, tap the Stop icon next to the job in the job list. To cancel all jobs in a running schedule, tap the red Abort button. This will cancel the currently running job and any remaining jobs in the schedule will not run.
