remote opc server

[ymuttath]

Hi
if i install wincc oa on one machine (main)
& install wincc oa opc sever on a another machine (remote), in which protocol does it connect to the main machine?

If you really only use an remote OPC UA server, it is simply connected to the event and data manager of the WinCC OA server via WinCC OA messages. In this case, you must use the event and data entries in your remote WinCC OA config file.

The communication between WinCC OA managers is using TCP/IP as protocol and the WinCC OA message format.
The WinCC OA message format is an own format and cannot be compared with any other standard protocol.
