Sequence of the example scenario
During the operation of a plant control system, the request, refusal and transfer of operator
authorizations could look like this:
Client 1, client 2, and client 3 are entered in the list of "available clients" on the server. All
clients are granted the right to connect to the server and to operate on the server.
● 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:
Client 1
Client 2
Client 3
Server
● 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:
Client 1
Client 2
Client 3
Server
● 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:
Client 1
Client 2
Client 3
Server
● 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.
