UPC-UA Server Access Control

[RhysGoodwin]

Hi,

I’m looking to use Rapid SCADA as an OPC-DA to OPC-UA gateway. Is it possible to control access to sets of tags?

E.g. Multiple OPC-UA usernames each with different access? Or multiple OPC-UA endpoints which expose different tags? For example, the Rapid SCADA has highly privileged access to the OPC-DA server but I want to limit the access on the OPC-UA side.

I notice that OPC-UA properties has a device filter, but I wasn’t sure how the devices in the configuration database relate to devices under the communicator.

Thanks
Rhys

Hi,
I suppose, yes.
Using the Administrator application, in Communicator – Data sources, create several data sources with the DrvDsOpcUaServer driver. Each data source works independently.

Note that OPC UA server in Rapid SCADA operates on Communicator level. It can access data of Communicator.

We are planning to implement access to calculated channels on Server level, but it’s in the future.

Thanks Very much Mikhail. I guess I would need create multiple UA servers and then set their ports in the xml configs? Are you able to explain connection between devices under the communicator vs devices in the configuration database?

Yes. Click the Properties button to open the data source options. Create a new configuration for for a data source. Find TCP port in the created file. Please let me know about the result.

On Server level, there are calculated channels. While on Communicator level, only data received from the devices.

A data source configuration file will appear in Communicator – Configuration files, named like DrvDsOpcUaServer.xml.
