Hi ,

I have faced problem in writting to measurement File. I have received an error state  (( These cannot be wired together because their data types (numeric, string, array, cluster, etc.) do not match. Show the Context Help window to see what data type is required.

The type of the source is cluster of 3 elements.
The type of the sink is Dynamic Data.))

How I slove this problem?

I have attached the labview file. i would be so grateful if you help to figure out the problem.

-From the help it's clear that it cannot have cluster- means cannot accept different data types.
-It can accept only one type of data.
-I cannot open the vi, can you post in LV12 by File>>Save for previous version.

Hi engkhalid,

-Yes, the Output of FFT-(RMS) is a cluster of three elements, which will not be accepted by Write to Measurement File.
-May be you can try Unbundling the cluster and build the array and then send the data, But this will alter how the data is saved in the file i guess.

-Please find the attachment for the modification i suggested.

I guess that's different problem. If this problem "Writing to file" is solved, please mark the solution and start new post for your new problem.

You should select proper reply as solution. And i guess it's my second post is the solution, not the third.
