Default is false. |
| ROCNegOperUnshelve | BOOL | Negative rate-of-change operator unshelve. Set to true by the operator interface to unshelve a negative rate-of-change condition. The alarm instruction clears this parameter to false. If both shelve and unshelve are true, unshelve commands take precedence over shelve commands.

| HHLimit | REAL | High High alarm limit. |
| HHSeverity | DINT | Severity of the High High alarm condition. This does not affect processing of alarms by the controller, but can be used for sorting and filtering functions at the alarm subscriber.
Valid = 1…1000 (1000 = most severe; 1 = least severe). Default = 500. |
| HLimit | REAL | High alarm limit. |
| HSeverity | DINT | Severity of the High alarm condition. This does not affect processing of alarms by the controller, but can be used for sorting and filtering functions at the alarm subscriber.
Valid = 1…1000 (1000 = most severe; 1 = least severe). Default = 500. |
| LLimit | REAL | Low alarm limit. |
| LSeverity | DINT | Severity of the Low alarm condition. This does not affect processing of alarms by the controller, but can be used for sorting and filtering functions at the alarm subscriber.
Valid = 1…1000 (1000 = most severe; 1 = least severe). Default = 500. |
| LLLimit | REAL | Low Low alarm limit. |
| Input Parameter | Data Type | Description |
| LLSeverity | DINT | Severity of the Low Low alarm condition. This does not affect processing of alarms by the controller, but can be used for sorting and filtering functions at the alarm subscriber.
Valid = 1…1000 (1000 = most severe; 1 = least severe). Default = 500. |
| MinDurationPRE | DINT | Minimum duration preset (milliseconds) for an alarm level condition to remain true before the condition is marked as InAlarm and alarm notification is sent to clients. The controller collects alarm data as soon as the alarm condition is detected; so no data is lost while waiting to meet the minimum duration. Does not apply to rate-of-change conditions or to conditions for which minimum duration detection is disabled. MinDurationPRE only applies to the first excursion from normal in either direction. For example, once the High condition times out, the High High condition becomes active immediately, while a Low condition waits for the timeout period.
Valid = 0…2147483647. Default = 0. |
| ShelveDuration | DINT | Time duration (in minutes) for which a shelved alarm will be shelved. Minimum time is one minute. Maximum time is defined by MaxShelveDuration. |
| MaxShelveDuration | DINT | Maximum time duration (in minutes) for which an alarm can be shelved. |
| Deadband | REAL | Deadband for detecting that High High, High, Low, and Low Low alarm levels have returned to normal.
A non-zero Deadband can reduce alarm condition chattering if the In value is continually changing but remaining near the level condition threshold. The Deadband value does not affect the transition to the InAlarm (active) state. Once a level condition is active, but before the condition returns to the inactive (normal) state, the In value must either: drop below the threshold minus the deadband (for High and High High conditions). OR rise above the threshold plus the deadband (for Low and Low Low conditions). The Deadband is not used to condition the Minimum Duration time measurement. Default = 0.0. |
| ROCPosLimit | REAL | Limit for an increasing rate-of-change in units per second. Detection is enabled for any value > 0.0 if ROCPeriod is also > 0.0.
Valid = 0.0…maximum possible float. Default = 0.0. |
| ROCPosSeverity | DINT | Severity of the increasing rate-of-change condition. This does not affect processing of alarms by the controller, but can be used for sorting and filtering functions at the alarm subscriber.
Valid = 1…1000 (1000 = most severe; 1 = least severe). Default = 500. |
| ROCNegLimit | REAL | Limit for a decreasing rate-of-change in units per second. Detection is enabled for any value > 0.0 if ROCPeriod is also > 0.0.
Valid = 0.0…maximum possible float. Default = 0.0. |
| Input Parameter | Data Type | Description |
| ROCNegSeverity | DINT | Severity of the decreasing rate-of-change condition. This does not affect processing of alarms by the controller, but can be used for sorting and filtering functions at the alarm subscriber.
Valid = 1…1000 (1000 = most severe; 1 = least severe). Default = 500. |
| ROCPeriod | REAL | Time period in seconds for calculation (sampling interval) of the rate of change value. Each time the sampling interval expires, a new sample of In is stored, and ROC is re-calculated. Instead of an enable bit like other conditions in the analog alarm, the rate-of-change detection is enabled by putting any non-zero value in the ROCPeriod.
Valid = 0.0…32767.0 Default = 0.0. |
