Hello,

I’m new to OPC, so my question might be stupid, but I was wondering if there are any standards or best practices of how to set up Address Space (nodes) on server. I’m not going to set up server Address Space nor even manage the server myself, but I’m trying to find out the best way or provide the easiest way to define what nodes the client will read or be able to recommend a specific settings.

Let me give you an example. I have 3 machines with some common attributes (lets say temperature, pressure and state).
1) Should every attribute be stored in separate node?
2) Should the nodes be in specific hierarchy, for example:
– Machine 1
– Temperature
– Pressure
– State
– Machine 2
– Temperature
– Pressure
… etc
3) Should the name convension of nodes (node IDs) reflect its hierarchy?
4) Are there any performance advances in specific heirarchy / Address Space settings?
5) Are there any standards reflecting my questions?

Thank you in anvance,
Best Regards,
Ladislav Asenbrener
