Functional Description:
The LED Display generic hardware operator provides access to an LED indicator resource in the physical hardware. When the generic operator is linked to a specific hardware resource, it will command that LED resource to turn on or off. If the hardware resource is so capable, the operator may drive it to assume one of three different colors as follows:

If the hardware resource is only capable of ON/OFF indication, it will turn ON whenever either input or are HIGH and will turn OFF whenever both inputs are LOW.
Digital input determines if the indicator will flash (when lit). If then the LED will flash.

User-Defined Properties:
Object Name. A string label that identifies the operator
Display Blinking Input. This property determines if input pin is visible in the schema diagram. Design Pad issues a warning upon processing the schema when the pin is visible but not connected. The warning message is not issued when the pin is not visible (when this property is not checked).
Display Green Input. This property determines if input pin is visible in the schema diagram. Design Pad issues a warning upon processing the schema when the pin is visible but not connected. The warning message is not issued when the pin is not visible (when this property is not checked).
Display Red Input. This property determines if input pin is visible in the schema diagram. Design Pad issues a warning upon processing the schema when the pin is visible but not connected. The warning message is not issued when the pin is not visible (when this property is not checked).

Comments:
•If the LED Display operator is in a sub-schema that is not currently active, its state (ON/OFF) will not be displayed. If no other operators are linked to that resource, the display is turned off and remains off until the sub-schema is activated.
