Read Request from UAExpert

Post by induna23 »

Hi,

I am using UAExpert client for verifying my newly created nodemanager for OPC CPP Server.

When I try to connect to the server, I get read request for Node Id : 2255, 84 , 2259, 2253 and so on.
My node manager implementation is not complete and I have many more nodes to be initialized and added to the address space.
Hence I would like to know how many mandatory nodes needs to be in the address space for verifying my
CPP Server with the UAExpert.

Thanks & Regards,
Indu

The NodeIds that are mandatory according to UA are defined in the OPC UA Specification Part 5 (Information Model), beginning in chapter 8.

The NodeIds the UaExpert needs as a minimum requirement are:
- Root and the Objects folder (it will browse them on connect)
- NamespaceArray (child of the Server node)
- State (child of Server/ServerStatus)

Please notice that these are the minimum requirements for the UaExpert to display reasonable information, but for full functionality the complete UA address space (especially the Types tree) is required to be implemented.
