Hi everyone

I want to expose some of my ignition tags to other OPC UA client.  
Where is the setting for that in ignition?  
Is it possible to limit some of tags to read-only?  
Is it possible to expose a selection of tags?

thanks

The setting is ‘Expose Tag Providers’ under the OPC UA Server Settings

[https://docs.inductiveautomation.com/display/DOC79/OPC-UA+Connections+and+Settings#OPC-UAConnectionsandSettings-IgnitionOPC-UAServer](https://docs.inductiveautomation.com/display/DOC79/OPC-UA+Connections+and+Settings#OPC-UAConnectionsandSettings-IgnitionOPC-UAServer)

Unfortunately there is no filtering or access control - it’s all or nothing.
