Figure 144: Configuration with XLNPROXY and GOOSEXLNRCV where only the mandatory data
All the information from the XLNPROXY to the SCSWI about command following status, causes for failed
command and selection status is transferred in the output XPOS. The other outputs may be used by
other functions in the same way as the corresponding outputs of the SXCBR and SXSWI function.
When a command has been issued from the connected SCSWI function, the XLNPROXY function awaits
the response on it from the represented switch through the inputs POSVAL and OPOK. While waiting for
the switch to start moving, it checks if the switch is blocked for the operation. When the switch has
started moving and no blocking condition has been detected, XLNPROXY issues a response to the
SCSWI function that the command has started. If OPOK is used, this response is given when
XLNPROXY receives the signal.
If no movement of the switch is registered within the limit tStartMove, the command is considered failed,
and the cause of the failure is evaluated. In the evaluation, the function checks if the state of the
represented switch is indicating that the command is blocked in any way during the command, and gives
the appropriate cause to the SCSWI function. This cause is also shown on the output L_CAUSE as
indicated in the following table:

The BEH input is 5.
The LOC input indicates that only local commands are
allowed for the breaker IED function.
