framing error in labview Riddle, Oregon

The Q is once an error like this occurs would an approach like this save me from further issues does anyone have experience doing something similar to recover from a 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.

It's easier than LabVIEW programming. More data might be available. 0 Kudos Message 5 of 7 (22,611 Views) Reply 0 Kudos Re: VISA: (Hex 0xBFFF006B) A framing error occurred during transfer.

It will not popup the error, but clear it instead. 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. Or is that the amount of free memory? So, somehow if i can supress the error I think I will be fine.

I wonder if the problem could be noise due to a long cable (the infrared-RS232 adapter that I ordered with the thermistor is several feet long) and/or a cheap RS232-USB converter 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. (It lists the error in decimal You may need to read the serial buffer more than once before its empty. There is not too much I can do about it regarding the connections or the fact that it is going through a USB- Serial converter (Its on a laptop) I am

i've also try all the possible baud rates. Can anyone tell me why? You may lose some data in the process. Share this post Link to post Share on other sites Create an account or sign in to comment You need to be a member in order to leave a comment Create

Can you let me know if this helps? Sorry to all for my bad eanglish.

Then, by using a VISA Flush I/O Buffer VI, you can clear any invalid data in the buffer. It will supress the popup window when you specify the exception action as "cancel error on match". For some  reason the default setting causes the serial port settings to revert  to VISA defaults (n.b. A list of error code is also given in LabVIEW help.

When last i looked there where about 1K bytes allocated for every opean which were NOT released until after LV shutdown for every open opeation. 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. Do you also keep ythe default (4096) buffer size? 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.

When I was running a USB->RS232 adapter at a higher baud rate than it actually supported, and didn't realize it.

Trust me I am not dissagree with you even if I do not know full answer. Internally, we now stick to a particular chipset that we have found to be the most reliable because overall its just less headache. (in our experience has been that the FTDI

For reasons I don't understand it was ok if the  serial settings had just been defined, but not when another vi which  used BusCommand.vi was unloaded from memory (say a subpanel I'm still thinking about how to modify this appropriately...Also, I am not sure what you mean by "(use a delay to avoid to use 100 of the CPU to do "nothing")".

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. But, I don't understand why this happen for normal RS232 pc port and don't happen with FTDI USB converter. I don't agree with this. This VI acquires data from a thermistor that has an infrared-RS232 (9 pin) adapter, which in turns plugs into an RS232-USB converter cable (because my laptop does not have a 9-pin

The solution was to try a different (and usually more expensive) adapter. 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 Whenever i Run LabVIEW, it will display this error message: Error - 1073807253 occurred at VISA Read in Basic Serial Write and Read.viPossible reason(s):VISA: (Hex 0xBFFF006B) A Framing error occurred during transfer. Under This can be wire-run too long, external noise, bad grounds etc.

You say simply clearing the buffer works and no side effects?

Each byte has a specific format with a start bit, data bits, parity, and stop bits as shown below. Maybe more than one issue but focus on serial.
