Define a Timer Control

The Timer control block is used to cause an action to occur at regular intervals. Most commonly, this will be used to refresh a query or a Date / Time block that is using the relative option. For example, you may have a grid that displays currently active alarms for a selected system and you want the grid to refresh every 5 minutes.

The other action the Timer Control can be used for is to advance through different rows of data in a grid at the time interval specified and display corresponding data for each row in a linked visualization object.

  1. Drag a Query Data block to the workspace and define the Query Data block as necessary.
  2. Drag a Timer Control block to the workspace.
  3. Connect the Timer Control block as input to a Query Data block.

  1. Enter the desired Timer Interval (seconds), or use the up and down arrows to change the time.
  2. Select the Query data block, and open the Input Bindings section.
  3. If you are using a Timer Control block to refresh data, select the Timer input from the drop-down list in the Refresh timer field.
  4. If you are using the Timer Control block to advance through different rows of data in a grid at the time interval specified and display corresponding data for each row, select the Timer Input in the Current Row timer field.
  5. Click the Apply button to save your changes.
