Error Code 1073807343 After Multiple Runs

[MDSI94]

Hi all,

I'm hoping someone here might be able to spot why I'm getting some strange behavior in a fairly simple spot of code I'm trying to get running. The idea for now is to just to step up the voltage output of a RIGOL DP821A over time, and when I first start up the computer and RIGOL, it works beautifuly. However, after a few runs of the program, and the exact number tends to change, I suddenly start to get the above mentioned error with possible reason, "VISA:  (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system." If it didn't work several times before breaking, I might think it was a connection issue, but that doesn't seem to be the case. I kind of need to get this working before I can get to other parts of the program, so if anyone has any experience with this problem, or even just some suggestions, I would greatly appreciate hearing them. The attached file is just a screenshot of the program.

Thanks,

-Matt

Your Read makes no sense with the number of bytes to read wired to the number of bytes that were written. There is not a correlation. You just set the number of bytes to read to some arbitrarily high number. Please use the error in/out connections and get rid of that silly sequence structure.

While there isn't a driver for your particular model, I would suggest you look at the drivers for other Rigol supplies.q

I'm pretty much brand new and self taught, so sorry there's some simple mistakes in the way of the bigger ones. I think I've got that polished up. I'll need to mess with the DP1000 series driver and see if it can do anything for me, but I'll let you know if the problems persist. Thanks.
