IEC 61850 - MMS - RREC question on AutoRecSt

[521AB]

Hello friends, a question for IEC 61850 people.
According to the IEC 61850 standard (Ed. 1), the Autorecloser logical node should report in the data object AutoRecSt:

1 if Ready
2 if In progress
3 if successful

Edition 2 of the standard says:

1 if Ready
2 if In progress
3 if successful
4 if unsuccesfull

what shoud RREC report if it is not in any of those states?
Autorecloser may be "not ready", and in this case it is not in any of the given states by the standard.

Is there any general rule for such situations? For instance, is it allowed to report "0" (zero) if the logical node (generally speaking) isn't in any if the foreseen states by the standard?

Anybody had such a problem (SCADA people, RTU people..)so far?

Thanks for any hint

It seems hat we are missing the status "other" or "others", that we have in different Logical Nodes (like the fault loop FltLoop in the fault locator, RFLO).
