Description
Positive rate-of-change condition acknowledged status. Set when a positive rate-of-change condition
is acknowledged. Always set when AckRequired is cleared. Cleared when a positive rate-of-change
condition is not acknowledged.
Negative rate-of-change condition acknowledged status. Set when a negative rate-of-change
condition is acknowledged. Always set when AckRequired is cleared. Cleared when a negative rate-
of-change condition is not acknowledged.
Combined High High condition active and unacknowledged status. Set when the High High condition
is active (HHInAlarm is set) and unacknowledged. Cleared when the High High condition is normal
(inactive), acknowledged, or both.
Combined High condition active and unacknowledged status. Set when the High condition is active
(HInAlarm is set) and unacknowledged. Cleared when the High condition is normal (inactive),
acknowledged, or both.
Combined Low condition active and unacknowledged status. Set when the Low condition is active
(LInAlarm is set) and unacknowledged. Cleared when the Low condition is normal (inactive),
acknowledged, or both.
Combined Low Low condition active and unacknowledged status. Set when the Low Low condition is
active (LLInAlarm is set) and unacknowledged. Cleared when the Low Low condition is normal
(inactive), acknowledged, or both.
Combined positive rate-of-change condition active and unacknowledged status. Set when the positive
rate-of-change condition is active (ROCPosInAlarm is set) and unacknowledged. Cleared when the
positive rate-of-change condition is normal (inactive), acknowledged, or both.
Combined negative rate-of-change condition active and unacknowledged status. Set when the
negative rate-of-change condition is active (ROCNegInAlarm is set) and unacknowledged. Cleared
when the negative rate-of-change condition is normal (inactive), acknowledged, or both.
Suppressed status of the alarm. Set when the alarm is suppressed. Cleared when the alarm is not
suppressed.
Disabled status of the alarm. Set when the alarm is disabled. Cleared when the alarm is enabled.
Elapsed time since an alarm condition was detected. When this value reaches MinDurationPRE, all
detected alarm level conditions become active (xInAlarm is set), and a notification is sent to clients.
Timestamp when the ALMA instruction detected that the In value exceeded the High High condition
limit for the most recent transition to the active state.
The number of times the High High condition has been activated. If the maximum value is reached,
the counter leaves the value at the maximum count value.
Timestamp when the ALMA instruction detected that the In value exceeded the High condition limit
for the most recent transition to the active state.
The number of times the High condition has been activated. If the maximum value is reached, the
counter leaves the value at the maximum count value.
Timestamp when the ALMA instruction detected that the In value exceeded the Low condition limit
for the most recent transition to the active state.
The number of times the Low condition has been activated. If the maximum value is reached, the
counter leaves the value at the maximum count value.
Timestamp when the ALMA instruction detected that the In value exceeded the Low Low condition
limit for the most recent transition to the active state.
The number of times the Low Low condition has been activated. If the maximum value is reached, the
counter leaves the value at the maximum count value.
Timestamp when the ALMA instruction detected that the In value exceeded the positive rate-of-
change condition limit for the most recent transition to the active state.
