indicating that the node has not executed

[Hooovahh]

A few properties are Read-Only but generally you right click the property node and choose Change To Write.  If this option is greyed out then it is read-only.

Some properties are read/write and some are read-only.  You can right-click the property and change from read to write if it's allowed for that property.  You can also right-click the property node itself and toggle all properties that allow it at once.

EDIT:  Must learn to type faster.

Create an X-Control that disables the indicator when it starts and changes the disable state the first time it is executed.

It may be overkill for one indicator but a BD-saver for many.

I appreciate all the ideas and discussion.  I will work on designing a solution based on these ideas.  Thanks

Hello:  I created a vi that consists of an LED that is greyed out or is not greyed out, using a property node.  This works fine.

   I create a sub-vi from this vi and it no longer works.  I guess that my property nodes are not referencing the Boolean indicator of the calling VI. 

  How should this be done correctly?

  The indicator vi that works is "indewenable.vi" and the calling program is "tester.vi".

Thanks for your help

Create a reference to the indicator and pass that into your subVI.
