Create browse path from node ID

I have an OPC-UA client written in C# which uses the TranslateBrowsePathsToNodeIds service to retrieve the node ID of a given browse path, like /2:SRV01/2:NodeA.

Is there a reverse function or how else can I restore the browse path if I'm given a certain NodeId?

Solution

  • There is no reverse correlation from NodeId to BrowsePath.

    In fact, there can be any number of BrowsePaths that lead to a given Node. It all depends on the structure of the address space. Part of what BrowsePath does is resolve those ambiguities by specifying exact reference relationships and browse names for each path segment.
