Adding a VISA device in MAX. 0xBFFF0079 error

[altran]

Hello,

I have an issue where I can add my Sorensen DCS60 power supply as a VISA TCP/IP device under "My System>>Devices and Interfaces" in MAX, but when I try to add it under my PXI-8196 remote system>> Devices and Interfaces, I get an error. 0xBFFF0079, VI_ERROR_INT_PROT. 

Can anyone explain why I am able to make it work on my PC but not the PXI system?

Thanks.

Howdy altran,

Have you installed NI-VISA onto your PXI-8196 RT controller? I assume you've installed NI-VISA onto your Windows PC (If not, you can download NI-VISA 4.3 here. ) But in addition to having VISA installed on your Windows PC, you also need to install NI-VISA onto your Real-Time controller. To verify that you have VISA installed onto your RT controller, follow these steps:

1. Open Measurement & Automation Explorer (MAX)
2. Navigate to your 8196 under Remote Systems
3. Expand the Software tree beneath your 8196 system
4. Verify that NI-VISA is listed.

If you don't see NI-VISA listed, then you can install it onto the RT controller by right-clicking on Software and select Add/Remove Software.



Instead of referencing your Sorensen power supply through a TCP/IP VISA Resource in MAX (aka a VISA alias), you might also consider accessing the power supply in your VI directly by using this syntax: TCPIP::xxx.xxx.xxx.xxx::INSTR, where the x's represent the power supply's IP address.
