Alarm worksheet

The Alarms folder enables you to configure alarm groups and tags related to each group. The Alarm worksheet defines the alarm messages generated by the project. The primary purpose of an alarm is to inform the operator of any problems or abnormal condition during the process so he can take corrective action(s).

The Alarm worksheet is executed by the Background Task module (see Execution Tasks). It handles the status of all alarms and save the alarm messages to the history, if configured to do so, but it does not display the alarm messages to the operator; the Alarm/Event Control screen object, available on the Graphics tab of the ribbon, must be created and configured in a screen in order to display alarms.

To create a new Alarm worksheet, do one of the following:

You can create multiple Alarm groups (worksheets) and each group can be configured with independent settings, such as message colors, history log enabled/disabled, and so forth.

Each Alarm worksheet is composed of two areas:
The settings configured in the body of each Alarm worksheet are stored in the Tags Database archive(s). Therefore, changes to the tags database may affect the content of the Alarm worksheets (body). Notice that each tag/type cannot be available in more than one Alarm group simultaneously because the Alarm Group is a property associated to each Tag/Alarm Type (e.g., Tag: Level; Alarm Type: Hi; Alarm Group: 2).
