12.3.7.1 Bay control (QCBAY) M16670-3 v7If the parameter AllPSTOValid is set to No priority, all originators from local andremote are accepted without any priority.If the parameter RemoteIncStation is set to Yes, commands from IEC 61850-8-1clients at both station and remote level are accepted, when the QCBAY function isin Remote. If set to No, the command LocSta controls which operator place isaccepted when QCBAY is in Remote. If LocSta is true, only commands fromstation level are accepted, otherwise only commands from remote level areaccepted.The parameter RemoteIncStation has only effect on the IEC61850-8-1 communication. Further, when using IEC 61850 edition1 communication, the parameter should be set to Yes, since thecommand LocSta is not defined in IEC 61850-8-1 edition 1.12.3.7.2 Switch controller (SCSWI) M16673-3 v6The parameter CtlModel specifies the type of control model according to IEC61850. The default for control of circuit breakers, disconnectors and earthingswitches the control model is set to SBO Enh (Select-Before-Operate) withenhanced security.When the operation shall be performed in one step, and no monitoring of the resultof the command is desired, the model direct control with normal security is used.At control with enhanced security there is an additional supervision of the statusvalue by the control object, which means that each command sequence must beterminated by a termination command.The parameter PosDependent gives permission to operate depending on theposition indication, that is, at Always permitted it is always permitted to operateindependent of the value of the position. At Not perm at 00/11 it is not permitted tooperate if the position is in bad or intermediate state.tSelect is the maximum allowed time between the select and the execute commandsignal, that is, the time the operator has to perform the command execution afterthe selection of the object to operate. When the time has expired, the selectedoutput signal is set to false and a cause-code is given.The time parameter tResResponse is the allowed time from reservation request tothe feedback reservation granted from all bays involved in the reservation function.When the time has expired, the control function is reset, and a cause-code is given.tSynchrocheck is the allowed time for the synchrocheck function to fulfill the closeconditions. When the time has expired, the function tries to start the synchronizing1MRK 505 393-UEN B Section 12ControlLine differential protection RED650 2.2 IEC 265Application manual
