OUT Status
When in AUTO mode the OUT reflects the Value and Status of the selected input (IN_x).
If there are no inputs used, or the number of inputs with GOOD status is less than the MIN_GOOD value, the OUT status shall be
BAD-Non Specific.
The SELECTED output shall have Good(NC) status, unless the block is out of service.
With the STATUS_OPTS it is possible selects the following options:
• Use Uncertain as Good: Set the IS_OUT status to Good when the Selected Input Status is Uncertain
• Uncertain if Manual Mode: The Status of the IS_OUT is set to Uncertain when the Mode is set to Manual
