Some applications require that the operator place selection must be performed without
any priority, that is, the desired operator places must be able to be set independent of
each other. Figure 100 shows an application example, where the operator from a switch
on a local panel can select either the position Off, Local, or Remote/Station/Local. If
Off is selected, it is not possible to operate from any place. If Local is selected, it is pos-
sible to operate only from the local panel.
If the switch is set to position Remote/Station/Local, it is always possible to operate
from the local panel and also from Remote or Station - independent of each other. In
this example, it is possible to operate from remote, station and local operator places, if
the position Remote is set in the station HMI. If the position Station is set in the station
HMI, it is possible to operate only from the station HMI and from the local panel.
The pulse timer in the figure below sets automatically the operator place selection to
position Remote at start up of the terminal, if the switch on the local panel is set to po-
sition Remote/Station/Local. That means, in this example, that operation from all three
operator places is possible.
