Connect 3rd Party OPC Client to 800xA OPC Server

I've written an application that will be used to only read data from a local DCS system via the sites 800xA OPC server.

Everything I've read in this knowledge store indicates that a client license is needed for my application to be able to get any data from the 800xA.

The only thing I haven't been able to ascertain yet is who or what provides this license - is it the owner of the 800xA OPC server (via some local registration process) or do I need to purchase a license for my 3rd party application?

- Or is it something akin to assigning something like read write permissions to a user account on a local area network?

The OPC client License is part of 800xA Core DCS Liecnse, this will be generated by ABB Engineer who has access to generate the Liecnse or it has to be procured from ABB. This will be installed with Aspect server which manages the thrid party OPC access.If you need any thrid party OPC Client talk to 800xA OPC Server, this license to be procured by vendore who has ABB DCS system.There is no limitation of read/write access with the license
