Assign a tag, expression, or direct reference to this read-only connection. At run time, the application reads the value at the data source and sets the backlight to a percentage of its maximum intensity corresponding to the value. For example, if the value of the connection is 75, the backlight will be set to 75 percent of its maximum intensity. This value will override the terminal's own backlight intensity setting.
If the value of the connection is 100 or greater, the backlight will be set to its maximum intensity. If the value is zero or less than zero, the backlight is set to its minimum value, that is, it will be turned off. The lowest intensity at which the backlight is still on is one percent.
Setting the backlight to zero percent is not recommended, for two reasons:
In both these cases, it may seem that the terminal is damaged or in an error state, when it is really fully functional.
