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
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:
