Read datas from table

[danil33]

In the below attached example:Is it possible to read from the table and display the values in read string box.Please reply.

Hi danil,

why don't you stick with your original thread(s)?

Your VI is very unclear and doesn't match with the question "Is it possible to read from the table and display the values in read string box."

- Yes, it's possible to read from that table.

- Yes, it's possible to display values in the read string box.

- No, it doesn't make any sense to do so!

- Your table is just an indicator. You already have all the values available somewhere else. So why read from the table? Read the original control (or shift register) of the interesting value(s)!

- Your "read string" is a display for data read from the serial port. No, it makes no sense to use that string indicator to display other data than that read from that port!!! Why do you want to misuse that string indicator?

OK.So, using that vi can I populate the table??Is it meaningful then?

Hi danil,

"So, using that vi can I populate the table??"

Yes, I think so...

"Is it meaningful then?"

As i don't know anything about those values or your serial communication I cannot decide on the meaning of those values. How can I then answer such a question?

How to populate that table by reading datas from an external device??

Hi danil,

it seems you're not the programmer of the attached VI. Why don't you ask them?

To "populate that table by reading datas from an external device" you have to take the "read string", analyze it's content to take over the contained values to the different controls (spped, current, temp, and so on) and then call the "Add" event. This will populate your table with values from the serial port...

Hi,

    Iam doing this one as the part of my study.So nobody has given us the datas.So from your comments I have understand that first of all datas will appear in the 'read string' box then only we can populate the table.Is'nt it?? If no device is available,Can I perform a loopback test?

Hi,

    Don't think that Iam interfering with another question.In the example 'serial 2 port reading' in labview2009(below attached).Can we read a table instead of a string??If yes what changes are to be make there??

I can see a very little sense in this thread.

Danil33, you should first state, what is your project supposed to do.

To your "loopback test" question.

You are asking for program solution, that is possible. However, your program architecture is very simple and doesn't allow you to do this easily.

You should communicate with HW (serial line) in other while loop and use some synchronization structure to co-op with your GUI loop.

Take a look at State machine and controlling parallel loops.

My question is 'Can we read a table instead of a string??'(table with rows and columns with strings and integers as entries.)Hope you saw the 'read string' box.I have no external devices connected.So I want that table to act as a simulator.Hope you can understand!
