Cluster Typ-Def Constant Reset

[jyang72211]

Hi all,

Ahhhhhh....  I have a typ-def cluster array with many elements in each cluster.  I created a vi, in which I delcared a 20 elements with specified values (a vi that contain constant values).  I made a minor change in my typ-def, and all the values that I keyed in got reset.  How do I avoid that in the future?  Thx!

One thing you can do is create an "initialize" sub-VI for your typedef, which wires the default values you want (specified as constants on the subVI's block diagram) into the appropriate places.  The output of the subVI would be your typedef, containing the default values.

Did that make any sense?

Here's a picture...

That's what your "initialize" subVI would contain.

Diane's suggestion is the only to solve your problem. Defaults values do not carry over from a typedef. The one thing you can do is save the defaults values you want in your typedef and recreate the constant. New constants created will pick up the current default values. However once you change the typedef all the constants you have will get reset.

See attachment for what I am doing. 

Diane's way will work fine.  I will just put it in my loop for all my elements in the array.  thanks!

You don't need the loop. You can use the Initialize Array VI to do this.
