How to turn LED Red for FAIL and Green for PASS?

[Sige]

Tri-Stated output. 

No result = black

Pass = Green

Fail = red

You can use property node for the Led Terminal. Change the node to Color property and wire the desired color.

If you are looking for only two different colors you may choose them by right clicking the LED and selecting properties.

There you will get a chance to select 2 colors one for 'ON' state and other for 'OFF' state.

Let me know if this solves your problem

Here is a small vi that lets you choose the LED color amongst three colors, using the property node as suggested.

I want to see the example for multi-state LED.

Would you please change the above attachment  to LV8.0?

Thanks

An indicator with more than two states is no longer a boolean, so why treat it as such???

Many examples have been posted here over the years. One possibility would be to use a colorbox indicator made to look like an LED.

For example have a look at my 4ColorLED.vi posted in this thread I am sure you can adapt it for your purpose.

Actually, I need 3 state boolean controller(not indicator).

Have any idea?

You should have read Altenbachs post.  A boolean has two states, on/off or 0/1.  Anything with more than two states is no longer a boolean.  Well that is just a play on terminology.  You want a three state controller.  You can right click on the 3-state LED examples and click Change to Control.  Or you could create an enum with three entries.  Or use this 3-position switch attached.
