Figure 319: 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:
