Array inside cluster doesn't have a name?

Solved!
Go to solution

Hey, hopefully this is a quick one (I tried googling but couldn't get an answer).


In my code I'm using a cluster of various data types, one of which is an array. The issue I'm having is I can't use unbundle by name to access the array- because it has no name.

The array starts off by being initialised using the initialise array subVI. I've attached a screenshot (ignore the rest of the code). 

 

Is there a way for me to assign a name to this array so that I can unbundle it by name? It would make certain parts of my code a bit neater as at the moment I have to use a regular unbundle.

 

Thanks!

Hi nishalc,

 

right-click the middle terminal of the bundle node -> create constant. In this cluster constant you set the label of the array…

(You should create a typedef for your cluster and use (Un)BundleByName anyway!)

EDIT: Just saw the other reply which explains it, never mind

 

What would be the advantage of making my cluster a typedef?

Hi nishalc,

 

when you change the typedef all instances of this typedef will automatically adapt…

 

(This becomes even more handy when you use subVIs to handle your cluster!)

I wrote a Nugget to answer that question that can be found here.
