LocSta is true, only commands from station level are accepted, otherwise only commandsfrom remote level are accepted.The parameterRemoteIncStation has only effect on the IEC 61850-8-1communication. Further, when using IEC 61850 edition 1 communication, theparameter should be set toYes, since the command LocSta is not defined inIEC 61850-8-1 edition 1.11.2.3.2 Switch controller (SCSWI) M16673-3 v6The parameterCtlModel specifies the type of control model according to IEC 61850. Thedefault for control of circuit breakers, disconnectors and earthing switches the control modelis set toSBO Enh (Select-Before-Operate) with enhanced security.When the operation shall be performed in one step, and no monitoring of the result of thecommand is desired, the model direct control with normal security is used.At control with enhanced security there is an additional supervision of the status value by thecontrol object, which means that each command sequence must be terminated by atermination command.The parameterPosDependent gives permission to operate depending on the positionindication, that is, atAlways permitted it is always permitted to operate independent of thevalue of the position. AtNot perm at 00/11 it is not permitted to operate if the position is inbad or intermediate state.tSelect is the maximum allowed time between the select and the execute command signal,that is, the time the operator has to perform the command execution after the selection of theobject to operate. When the time has expired, the selected output signal is set to false and acause-code is given.The time parametertResResponse is the allowed time from reservation request to thefeedback reservation granted from all bays involved in the reservation function. When the timehas expired, the control function is reset, and a cause-code is given.tSynchrocheck is the allowed time for the synchrocheck function to fulfill the close conditions.When the time has expired, the function tries to start the synchronizing function. IftSynchrocheck is set to0, no synchrocheck is done, before starting the synchronizing function.The timertSynchronizing supervises that the signal synchronizing in progress is obtained inSCSWI after start of the synchronizing function. The start signal for the synchronizing is set ifthe synchrocheck conditions are not fulfilled. When the time has expired, the control functionis reset, and a cause-code is given. If no synchronizing function is included, the time is set to0,which means no start of the synchronizing function is done, and whentSynchrocheck hasexpired, the control function is reset and a cause-code is given.tExecutionFB is the maximum time between the execute command signal and the commandtermination. When the time has expired, the control function is reset and a cause-code isgiven.tPoleDiscord is the allowed time to have discrepancy between the poles at control of threeone-phase breakers. At discrepancy an output signal is activated to be used for trip or alarm,and during a command, the control function is reset, and a cause-code is given.SuppressMidPos whenOn suppresses the mid-position during the timetIntermediate of theconnected switches.The parameterInterlockCheck decides if interlock check should be done at both select andoperate, Sel & Op phase, or only at operate, Op phase.Section 11 1MRK 504 158-UEN AControl172Application manual
