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
