limit OPC tags at user level

Postby Antoni Raj » 16 Nov 2015, 14:30

Hi ,

We are using Unified Automation UA SDK C++ Server Professional 1.4.3 in our OPC UA server.

We have several OPC UA clients at different sites that will be accessing this OPC UA server. When a OPC UA client browse our server, its address space has all the tags available in the server. We want to limit this at user level.
We want to use OPC UA to limit the tags that each user can see.
i.e for Example, When the OPC UA Client A browse , he should able to see some tags which should not be available for other client.

How do we achieve this?
Any help would be greatly appreciated.


Thanks
Antoni

Hi,

This feature is already available. In the latest version 1.5 of the C++ SDK we introduced functionality that allows the setting of a user authorization mask on an OPC UA node level.

Here you can find some general information regarding the topic:

Here you can find concrete sample code for user authorization:
