We are interested in controlling the Pfeiffer Maxi Gauge gauge controller through PC via serial port. We've so far based our program off of the standard Labview gauge driver offered by Pfeiffer at http://www.pfeiffer-vacuum.com/en/downloads/container. The pertinent file is attached.
The problem is, although it runs, the pressure reads 0 for each sensor (which is not true). I'm not sure whether the problem is something awry with the serial connection (bad serial cables, etc.) or something amiss about the program itself (I could be executing it wrong as well).
Also, the Baud rate resets itself after each run. When it should be set to 19200, it resets to 9600. I would be helpful to find out why this happens.
So, any advice would be great; though, if one has any troubleshooting tips for the serial connection, this would be beneficial as well. Thanks

You didn't include the subVIs and the lvlib that those VIs are associated with. Please zip these up and attach them along with your VI and then we will be bale to open it up and look at it. Thanks,

Ah, I see the URL didn't go through.
This one should: http://www.pfeiffer-vacuum.com/en/products/measurement/container.action
The download is at the right: "Maxi Gauge LabVIEW Driver 2009"

With opening the VI you sent to me it looks like you have the baud rate unwired, which means that it will use the defualt value of 9600. You need to wire a constant in to the initialize terminal. This could also be the reason you are getting bad data for your pressure.

Hello,
I am trying to do the same you have in the past, just trying to be able to read and write the pressure from a Maxi Gauge TPG 256 A using th serial port and Labview, however i am not able to find the driver for it "Maxi Gauge LabVIEW Driver", how you got them? Thanks.

Hi GerdW,
Thanks a lot for your message. I have asked them, i got the following: "There are no Labview drivers for the TPG256. Sorry"

Hi,
Could you please include the subVIs, if you still have them, since the link does not work anymore.
Thanks a lot.
