Hi Ilozan,

Have you figure out how to solve this problem? I have been having the same problem and even with different network architecture, the WinCC Unifield RT doesn't sees the second PLC, if you already know a solution, please tells me

I leave a screenshot of my network architecture in an attempt to solve this problem. In this case I tried to put all the inverters on the same subnet and create an HMI Connection for the PLC, but it still doesn't work.
