I'm using a more than one window in my HMI program. The Main Form is used to navigate to Either Manual or Auto mode. I am using the window open function's to do this. When I open Form 2 (Manual Form) I would like the PLC to know that I have the manual screen open and that all Inputs are being used as manual operations. Is there a way to have a bit be true when the Manual window is open and a bit be false when the window is closed?
Why not just set a bit in the plc to on when the form loads, and back to off again when the form closes.. then in your plc logic just examine the state of that bit
That's essentially what I want to do, I can easily right the logic in the PLC but I need the Advanced HMI software to set an Binary or any bit at any address high when I open the form. I'm not sure how to accomplish that.
Have you sorted this yet?
