When the protection trip is routed through the SXCBR function, consideration has to be taken to if the
blocking conditions for the breaker should also stop activation from the protection functions. If the trip
is allowed to override the blocking conditions used, the trip signal can be used for inhibiting the
blocking signals, such as BL_OPEN and CBOPCAP. An example is as shown in

12.3.9 Setting guidelines
The setting parameters for the apparatus control function are set via the local HMI or PCM600.
12.3.9.1 Bay control (QCBAY)
If the parameter AllPSTOValid is set to No priority, all originators from local and remote are accepted
without any priority.
If the parameter RemoteIncStation is set to Yes, commands from IEC 61850-8-1 clients at both
station and remote level are accepted, when the QCBAY function is in Remote. If set to No, the
command LocSta controls which operator place is accepted when QCBAY is in Remote. If LocSta is
true, only commands from station level are accepted, otherwise only commands from remote level
are accepted.
12.3.9.2 Switch controller (SCSWI)
The parameter CtlModel specifies the type of control model according to IEC 61850. The default for
control of circuit breakers, disconnectors and earthing switches the control model is set to SBO Enh
(Select-Before-Operate with enhanced security).
When the operation shall be performed in one step, and no monitoring of the result of 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 status value by the control
object, which means that each command sequence is terminated by a termination response.
The parameter PosDependent gives permission to operate depending on the position indication. At
Always permitted, it is always permitted to operate independent of the value of the position. At Not
perm 00/11 it is not permitted to operate if the position is in bad or intermediate state. At Not perm
cPos, it is not permitted to operate if the command is to move to the current position. At Not perm
cPos/00/11, it is not permitted to operate if the command is to move to the current position, or the
position is in bad 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 the object to

Example of how to allow the TRIP signal from SMPPTRC to override the blocked
for open conditions
The parameter RemoteIncStation has only effect on the IEC 61850-8-1 communication.
Further, when using IEC 61850 edition 1 communication, the parameter should be set to
Yes, since the command LocSta is not defined in IEC 61850-8-1 edition 1.
