Step 4.3. Set Alarm Options
You can determine how, when, and for what time period alarms will be displayed and reset on the Alarm Options tab.
1 | Use the same settings for all alarm levels. |
2 | Deletion requirements. |
3 | Manual reset allowed. |
4 | Alarm on delay. |
5 | Alarm off delay. |
6 | Printer repeat. |
7 | Auto acknowledge. |
8 | Auto reset |
9 | Alarm logging. |
10 | Change approval. |
1 | Use the same settings for all alarm levels |
Alarm options can be configured all alarm levels or separately for each level.
Clear or check Use the same settings for all alarm levels to apply options, as follows..
- Clear
The Alarm state drop down list is enabled.
Entries in the list reflect the String index selected on the Alarms tab before the last project configuration update.
When Use the same setting for all alarm levels is cleared the Alarm state list provides:
- Four states for analog points
- Alarm High (HiHi)
- Warning High (Hi)
- Warning Low (Lo)
- Alarm Low (LoLo)
- Two states for Boolean points.
- Alarm High (HiHi)
- Warning High (Hi)
Select alarm options for each alarm state.
Example
For an analog point:
- A High alarm state requires the alarm to be both acknowledged and reset before it can be deleted.
- A Warning High alarm state only requires the alarm to be acknowledged.
- The Use the same settings for all alarm levels check box is clear.
- The alarm states for deletion requirements are checked or clear, as follows.
Alarm State | Acknowledge | Reset |
High | Checked | Checked |
Warning High | Checked | Clear |
- The other two alarm states are configured according to their requirements.
- Check
The Alarm state dropdown list is disabled.
Selected alarm options apply to all alarm levels.
When you check Use the same settings for all alarm levels, the settings that display if you then clear the checkbox become the settings for all of the alarm states.
If you had entered custom settings for one or more states you must go back and re-select them.
2 | Deletion requirements |
Deletion Requirements are the conditions that must exist in order for an alarm to be deleted (removed from the system) as follows.
Check: | The alarm: |
---|---|
Acknowledge | Must be acknowledged to be deleted. Note: The alarm will be deleted as soon as it is acknowledged. If it is not acknowledged it cannot be manually reset.. |
Reset | Must be reset to be deleted. |
Both check boxes | Must be acknowledged and reset to be deleted. |
Neither check box | Can be deleted without being acknowledged or reset. |
3 | Manual reset allowed |
Manual reset allowed specifies if a user can reset an alarm.
Manual Reset | Description |
---|---|
Check | A user can manually reset the associated alarm. |
Clear | A user cannot manually reset the associated alarm. |
4 | Alarm on delay |
(Optional) Delays the display of the alarm on Alarm Viewers and other Alarm Management Interested Processes unless the point remains in an alarm state for the configured interval.
When an alarm condition is Detected for a point and if: | The Point Manager sends the information: | ||
No Alarm on delay is configured | Immediately to the Alarm Manager and all other Point Management Interested Processes such as CimView and the Event Manager. | ||
An Alarm on delay is configured |
After the delay time generates the Alarm on delay.
This means that Alarm on delay applies to:
|
||
Check box | Check to display the length and interval fields. | ||
Length | Length of selected interval time to delay the display | ||
Interval |
Options are:
|
||
Important: The minimum interval is 1 second. | |||
Note:
|
|||
5 | Alarm off delay |
(Optional) If a point goes from an Alarm state to a Normal state, CIMPLICITY waits for the specified time interval before reporting that the point has changed to a Normal state.
When a return to normal condition is Detected for a point and if: | The Point Manager sends the information: | ||
No Alarm off delay is configured | Immediately to the Alarm Manager and all other Point Management Interested Processes (e.g. CimView and the Event Manager) that the point has returned to Normal state. | ||
An Alarm off delay is configured |
Waits for the specified delay time to report the Normal state.
This means that Alarm off delay applies to:
|
||
Check box | Check to display the length and interval fields. | ||
Length | Length of selected interval time to delay the display. | ||
Interval |
Options are:
|
||
Important: The minimum interval is 1 second. | |||
- Alarm off delay can alleviate fleeting alarm conditions, for example, by allowing system engineers to adjust the dead band time between the changes in state to clear an alarm.
- If an alarm can be deleted from the Alarm Viewer after deletion requirements have been fulfilled, the alarm will be deleted. However, in other applications (e.g. the Point Control Panel), the point will remain in alarm state for the specified Alarm off delay time after the point has transitioned to a normal state.
6 | Printer repeat |
Printer repeat is the time that the Alarm Manager waits before repeating the alarm to all Alarm Line Printer (AMLP) processes. Setting a repeat time out will cause the point's alarm to be reprinted on the Alarm Line Printer until it is acknowledged, reset or deleted.
Printer repeat options are:
Printer Repeat | Description |
---|---|
None | The alarm will not be repeated. |
Timed | Number of minutes that the Alarm Manager should wait before repeating the alarm to all AMLP processes. Minutes are entered in a Minutes field that displays when Timed is selected. |
You have the ability in CIMPLICITY to enter your specifications for each stage in the sequence.
7 | Auto acknowledge |
Auto acknowledge specifies if and how an alarm can be automatically acknowledged.
Auto acknowledge options are:
Auto Acknowledge | Description |
---|---|
None | A user must manually acknowledge the alarm. |
Immediate | The Alarm Manager immediately automatically acknowledges the alarm. |
Timed | Number of minutes that the Alarm Manager should wait before automatically acknowledging the alarm. Minutes are entered in a Minutes field that displays when Timed is selected. |
8 | Auto reset |
Auto reset enables an alarm to be automatically reset.
An alarm can be reset:
- Manually.
- Automatically.
Because the condition causing the alarm no longer exists, and the process that detected the alarm condition automatically reset the alarm.
Auto reset options are:
Auto Reset | Description |
---|---|
None |
The Alarm Manager cannot automatically reset the alarm.
However, the alarm can be:
|
Immediate | The Alarm Manager immediately resets the alarm. The alarm will not repeat. |
Timed | Number of minutes that the Alarm Manager should wait before automatically resetting the alarm. Minutes are entered in a Minutes field that displays when Timed is selected. |
9 | Alarm logging |
Check if and when you want an alarm to be logged in the Alarm Logging box on the Alarm tab. You can select any or all of the options:
- Generate
- Acknowledge
- Delete
- Reset
When the configuration is applied, CIMPLICITY will add the point to its default ALARM_LOG. You can also apply these and more specifications in the Database Logger .
10 | Change approval. |
In the CIMPLICITY change approval system, you can select the point alarms that will require change approval.
