● Client 1, client 2, and client 3 connect to the server. All clients can see the project that is
running on the server on their screen.
If neither client executes an operation, all traffic lights are green at first:
● A user starts to operate on client 1 by pressing the touch screen.
Client 1 is immediately granted operator authorization since no other user is operating on
the server.
The traffic light for client 1 stays green. The traffic lights for client 2, client 3, and the
server turn red:
● The user on client 1 touches the green traffic light twice in quick succession (double-
click).
Client 1 is granted exclusive operator authorization. The traffic light for client 1 turns
entirely green. The traffic lights for client 2, client 3, and the server turn completely red:
● A user tries to operate on client 2.
Client 2 is not granted operator authorization because the user on client 1 has exclusive
operator authorization.
All traffic lights remain unchanged.
● The user on client 1 touches the green traffic light twice in quick succession (double-click)
and gives up exclusive operator authorization. Client 1 continues to operate.
The traffic light for client 1 turns green. The traffic lights for client 2, client 3, and the
server turn red:
