OPC UA server (2 interfaces)
I should install in the same field server one OPC UA server manager connected to two interfaces.
One it is necessary to interface SCADA to the CCTV system and the other is needful to connect SCADA with Level 2 system (to manage data).
Is it possible to have OPC UA with security access for all connections?
Could I link a group of variables to the first connection and another group of variables to the second connection?
Is it better to use the CNS function or DP groups?
Thanks a lot
The range of functionality may differ between the WinCC OA versions, e.g if new features are included in a new version.
If you define which DP elements shall be accessible via the WinCC OA OPC UA server every connected client can see all elements.
It is not possible to define a different address space for every client.
From a technical point of view it does not make a difference if you use a DP group or CNS. It is only a difference in the configuration.
For details according the security settings please have a look at the WinCC OA Documentation.
