Procedure
To set up a HMI connection to an S7-1500R/H redundant system, follow these steps:
1. In the network view of STEP 7, select a PROFINET interface of the HMI device.
2. Using a drag&drop operation, draw a line between the PROFINET interface of the HMI device
and a PROFINET interface of the S7-1500R/H redundant system.
The HMI device and the S7-1500R/H redundant system are networked together.

3. In the list of functions, click the "Connections" icon. This activates connection mode.
4. Using a drag-and-drop operation, draw a line between the HMI device and a CPU of the
S7-1500R/H redundant system.
The list "Connection partners" opens.

5. Select the S7-1500R/H redundant system in the list "Connection partners".
Result: You have set up a HMI connection between the HMI device and the S7-1500R/H
redundant system. The HMI connection uses the system IP address. The HMI device always
connects to the primary CPU.
