Hi,

1. The correct links are:

reference.opcfoundation.org/Core/Part3/v104/docs/7.5

qiyuqi.gitbooks.io/opc-ua/content/Part3/Chapter7.html

2. The customer tried two OPC Clients:
UA Expert - OPC UA Client
Softing OPC UA Client

Both clients are showing the Citect tree. See below a screen capture from Softing OPC UA Client.



So if two OPC Clients are showing the Citect tree with no problems, maybe there is something you can do to show it as well in your browser?


Thank you.

Michael

Hi,

Please see Citect/Aveva support reply.

"Because "HasChild" is an abstract reference type, having such reference is a violation of the OPC UA specification."
According to the OPC UA specification, the “HasChild” is indeed an abstract. However, it’s not a violation to have such a reference. The key point is that only subtypes of it can be used.
See reference:
UA Part 3: Address Space Model - 7.5 HasChild ReferenceType (opcfoundation.org)
7 Standard ReferenceTypes · OPC UA (gitbooks.io) - reference.opcfoundation.org/Core/Part3/v104/docs/7.5https://...n.org/Core/Part3/v104/docs/7.5

For your info, we have conducted extensive testing with our OPCUA server even connected to our driver and the handshake process appears to be satisfactory. We have a wide installation based for our OPCUA server. Since you are the first customer to raise such a question, we would require a more substantial argument to proceed with further investigation on our part.

Did you conduct any test using the following citect.ini?

[IOServer]DisableConnectivityPropertiesAndExtensions = 1

This parameter is used to disable the properties and extensions in the OPC UA server or the AVEVA Industrial Graphics (AIG) if there is no plan to use them. The default value of this parameter is 0.

I am open for discussion but as I said since the uniqueness of the request, I am doubtful that this is something from our side.

Hi

Thank you for your answer. Can I change something in my code to allow my customer to view the items in this folder?

Thank you.

Michael

Hi,
When browsing Citect Plant SCADA OPC UA Server, the browse component doesn't show the items under the BrowseProvider folder.
See the screen captures in UA Expert and in our browse dialog.




Any idea why?

Thank you.

Michael
