write string to serial port ?

[mihalis]

Hello! Thanks all, who help me build up this attached VI !!!

Small problem.

In a few words: I received date from serial port, my VI work with it, and I want pass string “sting I need write to port” to serial port. (see attached VI).

Data all time read from port and write to port.

I know, how work serial VISA, but I don’t know, how connect wire.

And second question: how insert subVI in VI from .llb?

Thanks!

Mikhail.

Hi,

to insert a subvi from a llb. Just do the same as for a "normal" subvi: Right click on diagram => Functions => Select a vi.

When you click on the llb it will be opened. Click on the vi you want to add: It is done.

In you diagram you used  the VISA write.vi in the write case. Use it again to write your string => copy/paste after Visa Read =>

disconnect top and bottom right wires from Visa Read => connect VISA Write to it.

Hi  Dai!
Thanks for answer.
I did as you said, but something  I did wrong.
Please, look at my VI. What is wrong?

Hi,

it looks alright. There is a missing vi (untitled one), I suppose you forgot to include it.

Not matter since I don't have the hardware I cannot test.

I suggest you debug it yourself using the Highlight Execution tool (the little light bulb next the run button).

Try to spot the problem: is the string you want to write correct? etc...
