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 IEC61850-8-1 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.
The parameter RemoteIncStation has only effect on the IEC61850-8-1
communication. Further, when using IEC61850 edition 1
communication, the parameter should be set to Yes, since the command
LocSta is not defined in IEC61850-8-1 edition 1.

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 grounding 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 must be terminated by a
termination command.
The parameter PosDependent gives permission to operate depending on the position
indication, that is, at Always permitted it is always permitted to operate independent of the
value of the position. At Not perm at 00/11 it is not permitted to operate if 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 operate. When the time has expired, the selected output signal is set to false
and a cause-code is given.
The time parameter tResResponse is the allowed time from reservation request to the
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 synchronism check function to fulfill the close
conditions. When the time has expired, the function tries to start the synchronizing
