Create variables
    Create variables that define a motor alarm, temperature, and individual ingredients.
     TIP: 
    Instead of creating variables manually, you can import controller variables in the offline mode. See Import controller variables.
- InProject view, create five variables by right-clickingModeland selecting .
 - Rename the variables by hovering-over each variable, selecting, and entering:

- Ingredient01
 - Ingredient02
 - Ingredient03
 - Motor1Alarm
 - Temperature
 
 - InProject view, selectMotor1Alarm.
 - InProperties, selectInt32and selectBoolean.The variable value type changes to Boolean. This is needed for the digital alarm that you will configure later.
 
Take a note of the variables location.
