Setting up HMI connections
Connect the HMI devices to the CPUs via separate PROFINET subnets.
1. Using drag-and-drop, draw a line between the PROFINET interface X1 of the "HMI left"
and the PROFINET interface X2 of the left-hand CPU.
2. Using drag-and-drop, draw a line between the PROFINET interface X1 of the "HMI right"
and the PROFINET interface X2 of the right-hand CPU.
Result: The HMI devices are networked with the CPUs.

3. In the network view, click on "Connections". This activates connection mode.
4. Using drag-and-drop, draw a line between the networked PROFINET interfaces of "HMI
left" and the left-hand CPU. The "Connection partners" list opens.
