3.17.10.7 Station authority level “L,S,S+R,L+S,L+S+R”
Station authority level “L,S,S+R,L+S,L+S+R” adds station control access together with
several different multilevel access scenarios. Control access can also be simultaneously
permitted from local, station or remote location. Simultaneous local, station or remote
control operation is not allowed as one client and location at time can access controllable
objects and they remain reserved until the previously started control operation is first
completed by the client.
