Hi Trevor,

You still need to improve the error handling, I just made the most iportant changes…

Hi Gerdw

Can I convert to LabVIEW 2020? or is it just a picture file?

Hi Trevor,

it's a snippet.

Read the LabVIEW help on "snippets"…

Hi GerdW

I got so far but cannot find the text mnemonic attached to the "end" control on lh side  and the "arrows" at the rh side of the loop box? Are these some type of data converters?

That is called Set File Position.

If you don't know about Shift Registers, then I suggest you take some LabVIEW tutorials.

Hi RavensFan

Is that what the missing mnemonic is? I tried searching bu cannot find the symbol?

My knowledge of shift registers is mainly from IC logic.

I will do a course but I am using an evaluation version at present to see if it will work correctly for what we require.

I don't know why you are calling it a mnemonic.  It is a VI.

Yes, that is the one you are missing.  Right click the block diagram  File I/O  >> Advanced File Functions.

For tutorials,
LabVIEW Introduction Course - Three Hours

A shift register is a special pair of tunnels that takes a value and returns it to the beginning of the loop for the next iteration.  Right click on a tunnel to change among its various modes.  A related entity that can often be used with much of the same functionality is a Feedback Node.

Thanks for the pointer to the VI

It now works as I need with the help from GerdW.

All I need now is a way to start to reading data when input string is greater than zero. 

Basically, start the sequence and capture/count up and collect data from the first string received that is not zero.

Any suggestions?

The suggestion is to code exactly what you said.

Comparisons, case structures, .....

Time to take those tutorials.
