Two port serial reading of a numerical value

[GerdW]

Hi Danil,

you have a potential race condition due to uncoordinated read/write access to one ressource...

[danil33]

How can we avoid such  race condition??Is there any other way to give continuous numerical input in this case?

Hi GerdW,

               I somewhat solved the issue by giving a constant value(1) in bytecount of VISA read.But that time we can read only single digit.While giving value 2 to bytecount it works but while stoping the VI it is showing time out error.Please make some comments to solve this issue.

You can check for the bytes available at the port and then you can read the data. Check the attached vi. This will not give you the timeout error as it only executes whenever you recieve any data at your port.

Hi Anand,

              Thank you so much.I also solved the issue by doing so in the attached vi.But I think mine is not the correct way.Anyway thankyou.

Hi,

     suppose we have another indicator,Can we display another set of values in that indicator?

[GerdW]

Hi Danil,

"Can we display another set of values in that indicator?"

Definitely YES!

[danil33]

So,how can we give input to the second indicator?

[P@Anand]

Just wire it. 🙂

[danil33]

Yes,both of the indicators display the same values.But Iam asking can we display different values( that is while indicator1 showing 34 at that time indicator2 showing 45)
