UI permission in distributed system

[yasas@applied.co.uk]

I have a distributed system with a main control center and several clients. Each client can be controlled by a panel with in the client project and also a panel from the main control center.
I want to make the panel on the main control center read-only when the client's panel is active and vice versa. Does WinCC-OA have built in functionality that supports this? if not what would be the best approch to solve this?

A predefined functionality is not available.
You could implement a function in your application that checks
-- if the connection to the distributed system is established
-- if a UI is running in the other system

Depending on the results you can define which actions can be started in the local UI.

You could use the '_lock' config to make the datapoint element(s) of the panel read-only for other users/clients. Or at least use one '_lock' config to signal the panel to be read-only.
