Figure 237: Configuration with XLNPROXY and GOOSEXLNRCV where only the
mandatory data in the IEC 61850 modelling is used
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:
