Unable to increase row index on a table

Many thanks devchander,

I have checked your VI and indeed it does display the data in different rows, the only problem I have is that the data that at the moment i have in a file should eventually be coming from an instrument connected to the computer. For the time being, dispatch (of the Quintox) has been delayed so I have been trying to make the program using a sample data file read and sent to the COM1 port. My VI in turn should read the data from the COM2 port (I'm using a NULL modem) and display some of the columns read by the sensor. That is the reason I have to be able to read the data from the COM2 port. Now, it seems that the behaviour of the VI is different when it reads data from a file than when data is read from the COM port. In your experience with LabVIEW, is this correct? Is there any way around it? Sometimes I think I'm just trying to do something that LabVIEW cannot do.

 Thanks for your efforts in helping me. 🙂

Could the problem be in the way I'm sending the data to the COM port?

Hi Eduardo,

In your COM1seria write.vi, you have enabled termination character recognition and set it as line feed constant.

so, a suitable interpretation after VISA read should work.

And i admit that in my limited experience with VISA,  i have not experienced such a problem,.

It has worked for me once i enable termination char and set it.

I came across this discussion posterd earlier in this forum just read it and see if it can help you.

Do a check on com write part if the data is being written in proper format

regards

Dev

Many thanks for your advice and help devchander.

Since I'm still unable to sort the problem out, I decided to dedicate some time to build some extra functionality in the VI (like doing something with the acquired data...)

I'll come back to the problem later on...

Thanks again
