The Alarm Grid has numerous run-mode options:
- A load indicator will let you know that Canvas is processing and loading data to your grid(s).
-
You can dynamically resize your screen and any controls within. See Resizing Screens for more information about resizing Canvas screens.
- Other run-mode options are list below:
To sort an alarm grid
- If a column has been configured to Sort numerically, click that column header to sort the grid. Clicking the column header moves between the three states: sort ascending, sort descending, and unsorted. A small arrow indicates the sort order.
To edit cells in a generic column in an alarm grid
- If a generic column allows editing, click any cell and type a new value. For example, a user could make quick data changes to facilities in a grid format. Edited values are not saved anywhere but in the grid, but they can be saved or otherwise manipulated via script.
To filter an alarm grid
- Click
next to the column header to filter the rows displayed in the grid. Click here for more information about using the filter tool.
To work with alarms via the context menu
The alarm grid context menu provides several actions that can be performed for alarms in the grid.
|
When an alarm is reported to the CAS, its state is "unacknowledged" meaning that the alarm is new and that a user or the system has not acknowledged its presence. An unacknowledged alarm may be identified by the color settings for the control (background, text, and border color), if configured to represent the point state of the associated point. Additionally, the control may blink to warn of a point in alarm, if configured to do so. The following table describes the fixed context menu options for the alarm grid. |
Alarm grid context menu |
| Standard Context Menu Item | Description |
|---|---|
|
Acknowledge alarm |
Right-click the alarm and select Acknowledge alarm to acknowledge an alarm. If the alarm has already been acknowledged, this option is disabled. |
|
Clear alarm |
Right-click the alarm and select Clear alarm from the context menu to clear the alarm and remove it from the grid. An alarm record remains in the alarm grid until it is cleared. An alarm must be acknowledged before it can be cleared. The action for removing a reset and acknowledged alarm is Clear alarm. |
|
Force clear alarm |
Right-click the alarm and select Force clear alarm to remove an alarm associated with a specified point tag that has not been reset or acknowledged. |
|
Hide alarm... |
Right-click the alarm and select Hide alarm... to hide the alarm. Hiding an alarm is useful for hiding low-priority alarms. An alarm cannot be hidden if it is not acknowledged or if it is suppressed. When you hide an alarm, you will be prompted to enter a comment for hiding an alarm in the Hide Alarms dialog box. The comment text is stored in the Comments property of the alarm. |
|
Unhide alarm |
Right-click the alarm and select Unhide alarm to unhide the alarm. |
|
Alarm suppression... |
Right-click the alarm and select Alarm suppression... to suppress an alarm on an ad hoc basis. Click here for more information about configuring alarm suppression. When you suppress an alarm, it is suppressed until it returns to normal or a specified period has elapsed. Suppression can be set up for a point so that any alarm that is reported is suppressed or can be performed on an ad hoc basis (that is, suppression is an action you can make on the alarm in the alarm grid). Suppression applies to all alarms for a point, not individual alarms. |
