First of all thank you very much for all this!

I'm also interested if you could quickly explain to me how this works and what the fifo functions mean?

And where could i insert data storageing in sql when the power is greater than 0? Should i put all this storageing outside of while loop or anywhere inside?

Thanks for any answer, you helped me a lot.

Hi,

one more thing : it seems ok

but when i stop the program and start it again all the values are shiftet by one. if i stop the program again and start it again all the values are shifted by one.( photo 1 and 2)

 

And on graph it show me only one value not all 4.

Then you need to implement a better synchronization between sender and receiver!

(Mind to downconvert your VI for LV2019 so I could open it?)

Hi Gerdw,

Here is 2019 version of my VI.

 ----Could you please take a look and help me so that the graph shows all 4 values, each on its own line?

----- And also could you give me a hinw where should i put procedure for saving in sql?

Are you sure that 100ms are enough time to wait for an answer of the instrument?

Consider using a termination char (does the instrument send any?)

OK here is a version that plot all four of your channels. I had to insert a build array to the values to make them all appear correctly. I also had to clear everything in the software in the INI state to get it to clear the previous data. That should make the system start correctly.

I will post a version the has explanations of what is going on in a few minutes.

hi dave tv,

Yes it is enough time, instrument response is great and all values are shown corretcly
