Index array and array size

[nust]

In the following attached llb.There is readbusconfig.vi ..I couldn't understand the working and understanding of this vi..I am not able to understand the logic of this vi .Especially the function of the index array and array size blocks..Please somebody help me in this..Thanks

For me your LLB is even worse.... Can't convert vi because the version is to 'early' 🙂

There is no such VI in the library you posted.

[nust]

the attached llb has been sent. but this can be opened in labview 7.1 . please help me in this for the things i have asked in my previous post.

I repeat: There is no VI called "readbusconfig" in the library you uploaded.

You said you wanted us to look at that VI. The VI isn't in the library. What exactly do you want me to help you with?

To reiterate smercurio, that VI isn't in your llb:

What there are, however; are a lot of sequence structures.

Hmm, did my answer disappear? However, the combination array size and index array if often used to get the last element of an array.

Hello!

It looks like you've received some good responses about the use of the Index Array and Array Size functions.

Array Size will output the actual size of any array it receives as input, which is useful for using the Index Array function. Index Array will output any element or group of elements from whatever array you wire to its input, depending on the index (starting position within the array) you provide. As mentioned in other responses, you can indeed use these functions together to identify the last element in an array, since they provide the effective location of the last element (size) and the means to read and identify it. 

If you'd like more information on these or any functions within LabVIEW, I'd suggest using the "Context Help" function, if you haven't already (in any VI, help>>show context help).

As far as the readbusconfig.vi, you'll have to upload the actual VI instead of just the llb file (although I was able to examine the SETUP_PWATON VI that calls it).

If you have any other questions about array functions, we'll be happy to help. In the meantime, I'll look for that VI from you.

Best,

I didn't say it was the only or best way, just a common one. 🙂 Could it be some inherited solution where delete from array wasn't possible until LV5 or similar?
