It is possible to speed up the command response for when the command has been
started by the switch in the breaker IED by connecting the inputs OPOK and
OPOK_VAL. Then the blocking check is only done until OPOK is activated and
confirmation of that the command has been started is given to the SCSWI function.
If the inputs STSELD and STSELD_V are connected, the switch in the breaker
IED is assumed to use selection. Then the SCSWI will wait for a selected
indication, STSELD input of XLNPROXY, before accepting selection, this
information is transferred to the SCSWI function from the XLNPROXY through
the group connection XPOS. If STSELD is not activated within tSelect of the
SCSWI function, the selection is deemed failed and it gives a negative selection
acknowledgement to the command issuer with the cause Select-failed. Further, if
the communication is lost, or the data received is deemed invalid, the selection will
also fail with cause Select-failed from the SCSWI.
