Is it possible to limit access to ignitions OPC UA server to specific items or tag providers? We have some third party software that has the ability to access data via an internal OPC UA client but i do not want to provide access to all of ignition. Thanks ---

Not right now, it’s all or nothing. In the near-term, the exposed tags functionality will start paying attention to the user for reads and writes, which will let custom tag permissions influence whether the connected user can read or write a tag if you configure the server to use the right auth profile. It won’t have any effect on what the client is able to see while browsing, and it won’t have any effect on tags provided by drivers configured in the server. ---
