I'd like to see what creative ways others have come up with for handling prompts on multi-HMI systems.
We recently added a second HMI for a customer and need to improvise how we are handling PLC-driven prompts. Currently, on the PanelView Plus, we have the PLC change the screen number for the prompt to display it, forcing the operator to make a decision. On the new Red Lion we just installed, we want to do something similar, but my concern is if the operator acknowledges the prompt on one, it will still exist on the other. Ideally, the second prompt would disappear upon interaction with the other, but that's not really possible. I'm leaning toward buttons with visibility.
