I have an application that requires 2 panels and a D2-250 CPU. I don't want the operators to be able to access both panels at the same time. Therefore, is there a way to set them up so that only one panel is active at any given time. For example, when panel 'A ' is in use, panel 'B ' will not be accessible. Panel 'B ' will have a button that when pushed would transfer control to it and render panel 'A ' inactive.

Use the button to set a bit that causes the disabled panel to navigate to a blank screen or a screen with "read only " objects on it while the enabled panel navigates to a screen that contains "read/write " objects.

For clarification, you can set up a tag for each panel to notify the PLC of which screen it is currently on, and also a tag for which screen it should go to on PLC request. An added advantage of this is that if the PLC sees that both are on the blank screen (for whatever reason), it can tell one of them to go to a live screen.

Thanks for the replies.
Let me see if my brain is engaged.
I will set up Panel 'A ' (PLC->Panel=v1400, Panel->PLC=V1402) and Panel 'B '(PLC->Panel=V1500, Panel->PLC=V1502).
When power is applied, 'A ' will display the 'Home ' screen for the process and 'B ' will display a screen with just a button on it.
When the button is pushed, 'B ' will display the 'Home ' screen and 'A ' will display the button.
That seems like it should work as long as the transfer is done when the 'Home ' screen is on, however if the process is in cycle and the screens transfer how do you ensure that the correct screen is displayed?

Use identical code in both panels. When the transfer button is pressed on panel B have the PLC set panel B to the same screen number as panel A then set panel A to the blank screen with the big button.
