Labview VISA Error 1073807343 for Rigol Power Supply

[Aman_Shah]

Hello,

I have a Labview program to test an assembly and it was working fine. Suddenly after sometime when I re-setup everything it started to give VISA Open error. I am new with Labview and not able to understand where to look. Please see below error message.

2/11/2020 4:31:18 PM,-1073807343,VISA Open in RIGOL DP1000 Series.lvlib:Initialize.vi->DP1308A.lvclass:Initialize.vi->DP1308A.lvclass:Instrument Handle FG.vi->Retreive Test Steps Data.vi->Process Execution List.vi->Aimtron Test Framework.vi

COM Port: ASRL53

Please make sure that the LINX firmware is loaded on the device (Tools>>LabVIEW Hacker>>LINX>>Firmware Wizard) that there are no other open connections to the device, then check the configuration settings, and try again.

I am referring blogs with similar error but nothing is helping out.Please review and provide the suggestions how to fix this issue.

Thank you in advnace.

Regards,

Aman Shah

Hello, Aman_Shah!

What do you mean by "when I re-setup everything" - did you reinstall all software? What kind of physical connection do you have to your power supply? Is it USB to COM converter, or direct COM port connection? Check COM port number in your program - maybe it is addressing COM port that does not exist.

Hello , 

I mean to re-setup is Hardware fixture for DUT and power supply setup. We are using labview to automate test of DUT in wich Arduino UNO is controlling all the switching. We are also installing LINX firmware in the beginning for Arduino.

We are using simple USB A-B for power supply to connect with PC. 

Also, we do not aware about where to check COM port in LABVIEW files as it was designed by someone else.

Please let me know if you need more info.

Thank you.

Why is the Arduino controlling switching?

The PC should be connected directly to the power supply.

Hello,

We are testing 8 boards in a panel, so arduino controlling that thing.

And power supply is directly connected to PC only.

Thank you.

Can you go into MAX and see which COM port power supply resides at? It looks like your software expects it at port 53. If that's not the case, you could try to find in your software (or hopefully config file) where it is specified, or go into Windows Device Manager and rename it.

Hello,

Thank you for the NI MAX hint and changing resource name. I cannot assign COM53 as it was assigned to something else.

After looking into the program I found that it was calling for RIGOL_DP1308A resource name rather than COM port. So by placing that name under Devices (VISA Alias) in NI MAX it started to work fine.

Thank you all for fixing this issue quickly.
