Hi,

Use the 'Search 1D Array' function and look for the "4". This will give you the index where it is found first. Using this index, read the next 20 elements using the 'Array Subset' function.

Then, pass the resulting index as the 'Start index' to the 'Search 1D array' again and repeat this process.

Hope this helps.

Rgds,

Khalid 🙂

Thanks for the idea , but is it possible to get a general value like, say i have more than 4 just not 4 then can i get the subset of 20 elemnts later.

I am attaching a VI which does what you want. The diagram is pretty straight-forward. Let me know if you don't understand anything.
