Hello we would like to get from AspenTech IP1 OPC UA server the nsurl (like below) knowing the tag name in the server.
Do you know a toll who allow to make this kind of search ? 

nsurl=http://aspentech.com/infoplus.21/OpcUa/Server/DA;b=AAAAAAEAAABfBwAAAABZdJYDAAA=

Kind regards.

Pierre.

There is no general search feature in UA because many servers will not know the address space they expose until a client asks for it (i.e. searching would require a recursive browse of everything which is resource intensive to implement and does not scale).

That said, if you know a path for node you can use TranslateBrowsePathsToNodeIs or simple call Browse multiple times.

Servers with indexed DBs may provide a server specific Method that allows searches based on globally unique names.
