How to handle multiple (1 to N) OPC-UA devices with same subscriptions


is there any possibility or example how to handle one to N OPC-UA servers with identical NodeID's and subscriptions as simple as possible?
Without copying the same nodes N times? Just adding additional IP for the next server.


As session is server specific you cannot. Two alternatives:

  1. Read them with client action readmultiple payload contains nodeIds that are always same
    Just change server endpoint.
  2. Use aggregator that will collect them all together, but it will place them to different addresses as nodeId is individual. Aggregator will change it depending how it is implemented. Into new namespace or new nodeId.
