Labview Framing Error


I have apps that run for years without restarting so even a slow leak is of concern to me. I got this error even though I open/close the port before every exchange (was required to make it reliable as it currently is) and many thousands of successful queries on the From: MissyD Date: Mon, 6 Mar 2006 22:40:52 -0600 (CST) Hi Ananda, I found a KnowledgeBase that discusses how to eliminate this framing error.

Each byte has a specific format with a start bit, data bits, parity, and stop bits. Which changes my thought of believing that the hierarchy of sub-vi's was loaded into memory on the initial loading of the main-vi.Hope this helps anyone.....R.

Me either. Check to make sure your cables are securely plugged in. 4. See in the case If anyone have things to improve please let me know. So this morning I decided to replace the sub-vi (on my main-vi on the USB stick)that read the serial port for this particular device to the copy of the sub-vi on

I opened an older version of the same general Vi that was saved on the computer to see if the issue was hardware or software driven. Yes that post is old but I work across LV versions and there only has to be one version that is buggy for me to adapt my rules. You may have a bad serial cable.Try another serial cable. 5.

Thanks for your response though. Framing errors are (provied the baud rate, parity and num start/stop bit is correct) an indication that the signal on the wire is bad.

The default configuration created through MAX should be able to carry through.

If your device is spewing data at a hight rate and you think there would be data in the serial ports hardware buffer then the Flush will take care of that.

I also had to "synchronize" the VISA drivers in MAX to what Windows had occasionally. When I was running a USB->RS232 adapter at a higher baud rate than it actually supported, and didn't realize it. so If I choose USB 1 it become com3, if I use USB2 it become com5. The downside of this is that when you run your VI, you will be grabbing the next reading from the serial buffer, rather than the last reading from your device, so

For who want to try to read the ticket, this is the address: http://forums.ni.com...message.id=2065 but it is in italian. Ben - have you reported it to NI? It could be also a hardware error on the build in port. But when you receive the same data (with either mark or space parity) you get a parity error (not a framing error).
