How to read a string via serial link

[neunited1]

Hello,

I am currently reading integer values (%d) using scan value function. However upon trying to read a float as (%f) with I32 indicator it is unable to read the string at all.

I feel as though I may be making a fundamental mistake.

Would appreciate any advice.

Many Thanks

Well, show us your code and include a typical string as diagram constant.

What is the meaning of "unable to read"? (broken VI? error output? zero output? wrong number? etc.)

Is your decimal delimiter a period or comma?

Your fundamental mistake is that you didn't even attach picture of what you are trying to describe.  (A VI would even be better, since VI = 1000p = 1000w, where p is equal to one picture and w is equal to one word.)  😉

Hi Altonback the error is: 

"Error -1073807339 occurred at VISA Read in MSc DC Motor Drive Panel_JKv3.vi"

The LabVIEW code is attached - the issue is occuring with potscale "float", if I remove the float from the string in my C code LabVIEW runs without an error and reads the integer values from my string.

Many Thanks
