Can OI server support OPCDA server ? Which license is required?

Hi James, I wasn't completely sure what you are trying to achieve. But here is a few thoughts.

Yes, if your OI-server in InTouch is supposed to connect to a 3'rd party OPC DA server, then you can use the OPC Client setup on the OI-Server.

Yes, if you want a 3'rd party application to connect to OI-server via OPC DA. Actually one of the enhancement in later releases is the ability so turn this feature OFF in case you do not need it.

The illustration shows in purple box the AVEVA application. OI-server being either OPD DA client or OPC DA server.

Thanks for your reply.
