So, use parity bit in your serial data format if possible.Related Posts Newer Post Older Post COMMENT! 1 comments: AnonymousOct 23, 2014, 10:56:00 PMWhen using LabVIEW, typically the port Make sure you have LabVIEW, NI Serial, and NI VISA on your computer.

the problem is now solved. Next by thread: Re: VISA: (Hex 0xBFFF006B) A framing error occurred during transfer. If i were to copy the example VI that you directed me to from Dennis, I would need to stop the while loop after, and only after, the "true" case has http://softacoustik.com/labview-error/labview-framing-error.php But If you have other application that takes these port it have to assign new port to that USB.
I'm not 100% sure but as I remember same error appeared. Daqmx Error Codes So, why does this error occurs only when I use the pc rs232 and doesn't occur when I use usb-adapter?

Framing errors are usually due to corruption of the serial data because there is something less than ideal about the physical connection. When the CPU my program was running on was really heavily loaded. (this is probably not your problem; I mean really heavily loaded, like 100% CPU usage for 30 minutes straight) It has a custom probe that will give you the baud rate.

The general sequence of events seems to be a "viParseRsrc", a VISA GetAttribute, a bunch of VISA SetAttribute related to port settings, VISA Read, and VISA close, which all occur with getThermistorData.vi 23 KB 0 Kudos Message 7 of 11 (7,134 Views) Reply 0 Kudos Re : Re: RS-232 framing error and I/O error JB Trusted Enthusiast 05-22-2007 04:18 AM Options Mark Thanks in advance Framing Erors are generally due to issue with the transmission medium. http://softacoustik.com/labview-error/labview-serial-port-framing-error.php I'm not really sure what's going on, if my VI seems to work perfectly in LabVIEW and problems arise only when it's imported into SignalExpress.

Trust me I am not dissagree with you even if I do not know full answer. But not perfect. What was happening was that any call to read/write to the serial port would open a VISA session with the access mode set to VISA defaults, not MAX defaults. Here is a more recent reference to VISA and leaks that recomends making sure they are the most recent version of VISA.
Actually, I was thinking of supressing this error message because in the error prompt if I click on continue it runs for a while again. 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 Share this post Link to post Share on other sites Grampa_of_Oliva_n_Eden 89 Prepper Members 89 2,767 posts Version:LabVIEW 2009 Since:2009 Posted March 7, 2009 QUOTE (TG @ Mar 6 2009, Maybe more than one issue but focus on serial.
I use only one line and one software. Just flushing the port and doing a retry would be my first attempt at handling this situation. I opened a ticket with NI and an engineer answered me that this happen becouse there are noise on the line and I loose some information on the package. NI-Spy is a program of ours that reads the ports, and reports whats going on.
Framing error can be detected by setting parity bit. This is the solution. So, the same code won't work for both. MissyS Member 03-06-2006 10:30 PM Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Highlight Print Email to a Friend Report to a Moderator Hi Ananda, I found a KnowledgeBase
If you probe the purple Visa Line you can get the same information after you have run the vi at least once with the probe active.
