ABB RELION Series - Station Authority Level L,S,S+R,L+S,L+S+R

When the station authority level “L,S,R” is used, the control access can be selected
using R/L button or CONTROL function block. IEC 61850 data object
CTRL.LLN0.LocSta and CONTROL function block input CTRL_STA are applicable
for this station authority level.
Station control access can be reserved by using R/L button or CONTROL function
block together with IEC 61850 data object CTRL.LLN0.LocSta.

3.16.11.7 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.
