Hello.  
I would like to know how to pass custom properties when switching between main windows while using Ignition Vision.  
For example, I have configured a P&ID screen in the Main window and called the Trend screen using a Tab Strip in a Docked Window. How can I transfer the variable values of the Custom Properties from the P&ID screen to the Trend screen?

For values that need to be maintained across all windows in a Vision application, use Vision Client Tags, not window or component properties. If necessary, bidirectionally bind a component property to a Vision Client Tag.
