# Steps to Design (Alarm)

You can learn how to design alarms in this section.

Note:

- To create variables, see Steps to Design (Variables, Array, Structure).
- For sample projects, see Setting Examples.

- 1. Add Alarm
- 2. Add Object
- 3. Add Script

Add the following alarms and set the contents.

- Alarm Group
- Alarm

Here we will create a BOOL type alarm that will be triggered when Var1 gets ON.

Note:

- In the [Variable Selector] dialog box, you can select and add multiple variables at the same time.

  - [Ctrl + Click]: Select variables one by one.
  - [Shift + Click]: Select range of variables.
  - [Ctrl + A]: Select all variables.
- Select the check boxes of multiple alarm types to register them at the same time.

Add the following objects on the screen and configure its properties.

- Alarm Summary object (used to display the alarms.)

  Note: For details of Alarm Summary object, see Displaying Alarm.

- Switch object (used to change the status of the alarm to [Acknowledge].)

  Note: To operate Switch object create script.

Add script for the switch to work.

Here we will add a script to change the alarm status displayed in the Alarm Summary object to "Acknowledge" by Switch1.
