The values of all the 24 terms in the internal variable must be initialized no matter how many terms will be used in this internal variable. By default, when you create an Apollo Internal Variable object, the value of all terms is set to FALSE. Initial values can subsequently be changed in accordance with the rules set for the corresponding Apollo equipment.

The initial values of the terms are set as follows:

1. Go to the Apollo Internal Variable object settings panel.
   
2. Set the checkboxes next to the numbers of those terms that should be set to TRUE (1) when writing the internal variable to the controller.
3. Click the Apply button (2).
4. To save the changes to the controller, write configuration to hardware.
