Hello,

I am very new here to this forum so i apologise if I write anything wrong in advance.

I have a school project I would like to make, however i am stuck at a problem and I do not know how to go forward. 

The project consists of a Unitronics V350 controller, which has a simple program running on it. I have made a server, using UniOPC server with a serial connection with the controller (baud rate, COM port etc...). 

In TIA portal, I have created a project, inserted a PC station, added a IE general comm module and a HMI WinCC RT Advanced module. I added a screen to HMI_RT_1 and the two HMI tags (one Int and one Real). 

Under connections, I added a new connection and a OPC UA communication driver. 

However, i am unsuccessful at establishing a connection. Is there anything I am missing? What should be written in the "UA server discovery URL:"? Any tips or guides would be really appreciated. Furthermore, how should a tag from Unitroncis Visi Logic be written for the WinCC to read it correctly?

Thank you all in advanced!

Hi!

In section 2 of the following FAQ it's described how to configure the HMI Advanced as an OPC UA Client.

Communication via OPC UA with SIMATIC HMI systems

Under "UA Server discovery URL" you must enter the URL of the OPC UA Server.
