If the Panel should act as OPC UA Server then you cannot set that some tags are not visible/writable with OPC UA Client. The HMi will access all of its tags. If the OPC UA Server is a S71500 then you can define which Tags should be visible/writable. There are severaly ways-. in the new FW you can define a userdefined Server interface. and also you can actiavte the OPC UA Access globaly in any DB settings. Bye Murof
