      TIP:
      Tips:
      • Bind a PDF command property value to a tag in a controller to change the PDF property dynamically on the HMI device. If there is a problem with a tank, bind the specific page number of the PDF document to a tag for user assistance. The controller opens the document to the specified page explaining how to fix the issue.
      • Project events do not support PDF commands.
