Some applications require that the operator place selection must be per-
formed without any priority, that is, the desired operator places must be
able to be set independent of each other.
Fig. 20 shows an application example, where the operator from a switch
on a local panel can select either the position Off, Local, or Remote/Sta-
tion/Local. If Off is selected, it is not possible to operate from any place.
If Local is selected, it is possible 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 - inde-
pendent 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 MMI. If the position Station is set in the station MMI, it is pos-
sible to operate only from the station MMI 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 position Remote/Station/Local. That means, in this
example, that operation from all three operator places is possible.
