Problem connecting to Realtime system to download or run in debug mode

[DPearce]

I have updated my LabWindows\CVI to 2013. I have a PXI system with a PXIe-8101 controller. The PXIe-controller has a real-time OS installed. I have been programming this system for a while now so I am not exactly a novice anymore. The first time I tried to install the program to my real-time target I got a message which said "LabWindows/CVI cannot connect to the real-time target." It also said " .... The version of the LabWindows/CVI Run-Time Engine for RT must be compatible with the version of the LabWindows/CVI development environment."

So I figured that was the problem. My next step was to go into MAX and sure enough was getting all sorts of flags and errors when I used the real-time software Wizard in MAX by right clicking on the Remote software and clicking on Add/Remove Software. And like I suspected there were several flags indicating a software differences. My next step was to update the software in my real-time target to resolve the problem. After I did that I compiled the code and installed it on my remote system.  Everything seemed OK.

The following Monday I restarted LabWindows/CVI and made a couple of changes and tried to build and install to my real-time target. I get that same message as in the first paragraph. So I thought I might not have real-time system  booted up correctly or something like that so I checked all of that and it looked OK. Next I opened up MAX and it could see my real-time target just fine.

When I had my LabWindows/CVI 2012 I did not have this problem. I think maybe there is some incompatibliity issues with my LabWindows 2013; has anyone had a similar problem? I am able to get around the problem by building the release version and copying it to the PXI with CuteFTP V9.0 but I cannot do run my program in debug mode with my LabWindows/CVI and if you may have noticed I have other problems which is in another post I put in next week. I am hoping the problems are connected and I can kill two birds with one stone LOL.

I appreciate any suggestions.

Thanks,

Hello,

I want to make sure I'm understanding what you are doing in the LabVIEW project. According to the Getting Started with the LabWindows /CVI Real-Time Module manual, these are the steps to install software on the RT target:

1. Launch MAX.

2. Find and expand your RT target under the Remote Systems item in the MAX configuration tree, right-click Software, and select Add/Remove Software. When you select Add/Remove Software, MAX launches the LabVIEW Real-Time Software Wizard. This displays all the National Instruments software and drivers installed on the host computer that you can install on a selected RT target.

3. Select the software you want to install on the RT target, click the icon next to the software, and select Install the feature.

You need to install LabWindows/CVI Run-Time Engine for RT to add support for LabWindows/CVI RT applications on the RT target. This component is required for all LabWindows/CVI RT applications.

The forum post here solved this same issue by installing missing drivers based on this KnowledgeBase article.

Also, LabWindows/CVI 2013 SP1 has been released. Service Pack 1 (SP1) has many  useful bug fixes (listed here), so I recommend upgrading to LabWindows/CVI 2013 SP1 if possible.

I have SP 1. Did not see anything about the exact problems I have in the bug list but did notice there are some problems with TestStand that look like they are unresolved. I found a workaround for dowloading the dll and I will have to getby with out remote debugging for a while. Hopefully I will see and fix for that come down the pipe soon.

thanks

I'm glad to hear you have found a workaround to solve the issue. I just also wanted to point out that the version of LabWindows/CVI and the RT module need to be the same. AS for the failure to connect issue, make sure the status of your RT target in MAX is connected and running. If you wanted to troubleshoot further, you could try doing a clean install of LabWindows/CVI RT module.
