Valid values are 1, 2, 5, 10, 15, and 30 minutes. Other numbers entered are rounded down to the closest valid value. For example, 3 is rounded down to 2. 9 is rounded down to 5. Any value greater than 30 will be rounded down to 30 minutes.

thanks for your replay but i don't need this i read in Vijeo desinger help the next :
16.5.2 Changing the Backlight Color






You can change its backlight color between amber and red on some target machines. You can use the amber backlight color to indicate normal operating conditions and the red backlight color to indicate an alarm or a critical error on the target machine. See Appendix 5, Hardware Specifications to check if your target supports this feature.

1. In order to activate the management of the backlight color at run time, select the Target node and display its properties.

1. In the Backlight Control property, select the checkbox and enter either an integer variable or an integer expression. You can click the ellipsis button to display the Variables List.

At run time, the value of the integer variable or expression defines the backlight color.

Backlight Control value --------------------------Backlight Color
--------0-------------------------------------------- Amber
--------1--------------------------------------------- Red
Any other value ---------------------------------------Red

1. Set up a script, alarm action, or some other method to change the Backlight Control variable's value when an alarm or error occurs.
2. Also set up a way to reset the value of the Backlight Control variable or expression when the alarm or error is resolved.

I need how i can do this "Set up a script, alarm action, or some other method to change the Backlight Control variable's value when an alarm or error occurs"
