Uncertain Sub-status
Description
There is no specific reason why the value is uncertain. Used for propagation.
Whatever was writing this value has stopped doing so. (This happens when an input is
disconnected by a configurer.)
Set when the value is written when the block is not Out of Service.
Set when the value of an input parameter is written while the block is Out of Service.
Set if the value is at one of the sensor limits. The Limits define which direction has
been exceeded. Also set if the device can determine that the sensor has reduced
accuracy (e.g. degraded analyzer), in which case no imits are set.
Set if the value lies outside of the range of values defined for this parameter. The
Limits define which direction has been exceeded.
Set if a value derived from multiple values has less than the required number of Good
sources.
Good (Non-cascade) Sub-status
Description
There is no specific reason why the value is good. No error or special condition is
associated with this value.
Set if the value is good and the block has an active Block Alarm.
Set if the value is good and the block has an active Alarm with a priority less than 8.
Set if the value is good and the block has an active Alarm with a priority greater than or
equal to 8.
Set if the value is good and the block has an unacknowledged Block Alarm.
Set if the value is good and the block has an unacknowledged Alarm with a priority
less than 8.
Set if the value is good and the block has an unacknowledged Alarm with a priority
greater than or equal to 8.
