Creating a "Toggle Switch" using a button in Graphics Studio

Is there a way to create a "Toggle Switch" using a button in Graphics Studio? I'm trying to set it up so that the button will reference the current status (i.e. Mode.Actual = CAS) and change it to the other status (i.e. Mode.Actual = MAN).

  Hi Micah, 

  Yes, there is.

  You can create a button that has a custom script responsible for writing the right mode based on the current mode and updates its caption to avoid confusion. You could try this and adjust it to your loop name:

  var current_mode
  
  current_mode = (await DLSYS.ReadAsync("LIC-101/PID1/MODE.ACTUAL")).Value
  
  if (current_mode == 8) {
      DLSYS.WriteAsync("LIC-101/PID1/MODE.TARGET", 16) /* Change Controller Mode to AUTO */
      Dsp.Button1.Label = "Change to MAN" /* Change label to indicate next click will be to Manual */
  }
  
  if (current_mode == 16) {
      DLSYS.WriteAsync("LIC-101/PID1/MODE.TARGET", 8) /* Change Controller Mode to MAN */
      Dsp.Button1.Label = "Change to AUTO" /* Change label to indicate next click will be to Auto */
  }

  In order for the button label to be correct, add this script to the display OnOpen script:

  var current_mode
  
  current_mode = (await DLSYS.ReadAsync("LIC-101/PID1/MODE.ACTUAL")).Value
  
  if (current_mode == 8) {
      Dsp.Button1.Label = "Change to AUTO"
  }
  if (current_mode == 16) {
      Dsp.Button1.Label = "Change to MAN"
  }
  

  Controller mode values are:

  8 = Manual

  16 = Automatic

  32 = Cascade

  I hope this helps,

  Thank you for your help. The first section worked however I am having a hard time finding where the "display onOpen script" is.

  In reply to Micah Dudley:

  The OnOpen script field can be found at the display level (nothing selected). Look for the Configuration Pane on the right-hand side of the screen.

  The second tab on that Configuration Pane is the Interaction tab. You will see the OnOpen field first on the list.
