NI LabVIEW OPC UA APIs Discussion

[FelipeC]

I've discovered that the problem happens in Windows too, not only in CompactRIO. After 45 minutes precisely Labview closes without any error message.

Could you use some tool to get the crash dump on Windows?  For example, you can use the "procdump" from microsoft. (download from http://technet.microsoft.com/en-us/sysinternals/dd996900.aspx)

Steps to creat the dump:

1. Run your application

2. Run "cmd.exe"

3. Go to the foler where the "procdump.exe" is.

4. Run the following cmd :

    "procdump -ma -e LabVIEW.exe"

So, after the crash of LabVIEW happens, the dump file will be created under the same folder.

Ok I'm getting the dumping write now.

I've just figure out that I only need to connect to OPC server to get the crash.

I got it. A 400mb file. How do I open it?

[FelipeC]

This is the mininum code that causes the crash.

You can open it with Visual Studio. But maybe you cannot see the function names, since you don't have the PDB files to interpret the symbol of the call stack. Can you upload your Dump file to ftp://ftp.ni.com/incoming? 

So what your did is that connect a OPC UA client to a OPC server and wait for 45 minutes then LV crashes? Does the OPC server stop or reboot after 45 minutes?

The Community is just for some discussion. If you have some crash issues, it's recommended to use the official tech support. The NI local contact can be found in www.ni.com/contact. The Application Engineer is better trained for support and will response quickly.

For me, I will also look into the crash dump to find what's the problem of our product. Hope that will be helpful.

Exactly, I just connected to Kepware OPC UA server and wait 45 minutes to the crash. It always happens after the 45 minutes. Nothing happens to the OPC server.

Is there a plan to provide an "I/O Server Wizard" to setup OPC UA on RT targets (similar to Modbus I/O Servers)?
