Hello,

Our Ignition server connect DCS OPC-DA server (OPC protocal). I created tags and logged tag history in Ignition designer. Can I use 3rd party OPC-UA client connect Ignition OPC-UA server and export Ignition tags data?

Thanks,

Apisit

Yes. In the configuration of the [Ignition OPC server](https://docs.inductiveautomation.com/display/DOC79/OPC-UA+Connections+and+Settings), there is a setting called “Expose Tag Providers” that enables publishing of your SQLtags back out the OPC UA server to other clients.
