I have built the OPC UA example with few warnings that look unrelated to this problem.

Platform/compiler:

Code:
$ uname -a
Linux ubuntu16 4.4.0-78-generic #99-Ubuntu SMP Thu Apr 27 15:29:09 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ g++ --version
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609


However, when I run it, I see some "Bad status" messages:

Code:
$ ./opcua_example

And later, after I successfully connect with (non-Matrikon) OPC client:
Code:

The result is that my client only sees few nodes:
Code:

[NAMESPACE]      [NODEID]                       [BROWSE NAME]            [DISPLAY NAME]
--------------------------------------------------------------------------------------
 0                     61                        FolderType               FolderType
 0                     2253                      Server                      Server
 1  /ObjectsFolder/MyFolder                      MyFolder                  MyFolder


Two questions:

1) Why are there "Bad Status" messages at startup (before any client connections)?
2) I assume later "Bad Status" messages are the reason I can't see any data. Is it obvious from the logs what is causing this?

Thanks

Hi Alex,

Thanks for reaching out to us.

As per error code [0x80350000], it states that the "The attribute is not supported for the specified Node.". Can you please check what attribute you have used for the node which is giving error.

Regarding the other error code, just before client connection, it looks like that the requested item was not found but to identify which item, we need to gather Wireshark and check nodeIDs.

If possible, can you send me Wireshark of both scenarios, so we can help you further. Also, I would like to know if you have purchased the SDK or you are using are demo version from website.

Regards,
Shubhi Gogna

Thanks, [0x80350000] may be my client request issue, I'll look at that. But why [0x803e0000] at startup (before client is connected)? I am using unmodified demo server.

Hello Alex,

This warning can be ignored as it is because of missing optional property of a DA variable. Hence, this error can be ignored.

Please reply back to me in case you need any further assistance or have any questions.

Regards,
Shubhi Gogna
