R/W Options which the user may select in the block processing of
status.
No option selected
Setting:
• IFS if Bad IN: Set Initiate Fault State status in OUT if the
status of IN is "Bad".
• IFS if Bad CAS_IN: Set Initiate Fault State status in OUT if the
status of CAS_IN is "Bad".
• Use Uncertain as Good: If the status of IN is "Uncertain",
treat it as "Good" otherwise treat it as "Bad".
• Target to Man if Bad IN: Set the target mode to "Man" if the
status of the IN parameter is "Bad". This latches a PID block
into the "Man" state of the input ever goes "Bad".
• Target to next permitted mode if BAD CAS_IN

R This alert is generated by any change to the static data. -
Unacknowledged R A discrete enumeration which is set to "Unacknowledged"
when an alarm occurs, and set to "Acknowledged" by a write
from a human interface device or other entity which can
acknowledge that the alarm/event has been noticed.

the alert has been reported.
