I am trying to connecte a stahl ER-300 instrument with labview. The Stahl is connected to my laptop via a convertor Serial/USB port.
When I run the program, I am getting this error Property Node (arg 1) in VISA Configure Serial Port (Instr).vi->Untitled 1.vi
the driver of the convertor is well configurated and my laptop is reading it as a COM4 and I don´t understand why I am getting this error.
You will find attached the programme.
I need your help
Solved! Go to Solution.
The error says that an input parameter is invalid at the configure serial port VI....did you check you had wired up that node correctly?
Move the configure serial port VI down and....
It's not wired! Wire the VISA resource name through the VI.
OH ! And I was looking for the error since 3hours now 😛
Thank you. It's working
I had same error, it is very intermittent with "Error -1073807246 Property Node (arg 1) in VISA Configure Serial Port". I found when I close the VISA port and reopen, it generates error on VISA configuration. Waiting for few seconds will help, but the root cause is that the VISA configuration sometimes does not take "close and open" in short time.
You know the old joke about the person saying to the doctor, "It hurts when I do this," and the doctor replies, "Well don't do that then!"
Don't do it. It's not VISA that is causing the error - it's whatever is connected to the serial port isn't resetting itself fast enough. Why are you constantly closing, opening and reconfiguring the port, anyway? You should configure it once, open it once, do all your stuff in between and then close it when you are finally done.
What you are doing is analogous to calling someone up, saying a sentence, hanging up and then calling that person back with the next sentence.
