Communication mainly over system IP address: If the communication partner uses a device IP address and the CPU with
this device IP address fails, communication between the communication partner and S7-1500R/H also fails.

function manual.
4.4.3 HMI devices
HMI devices are used for machine-level process visualization and control. You use the same
HMI devices for the S7‑1500R/H redundant system as for the standard S7-1500 system.
Using HMI communication, one or more HMI devices exchange data with the CPUs . Examples
of HMI devices are HMI Basic/Comfort/Mobile Panel.
The connection of the HMI device to the redundant system depends on the specific
application. In STEP7, you can configure the following communication options:
•
The HMI device communicates with the redundant system over the system IP address.
•
The HMI device communicates with the R/H-CPUs (for example for diagnostics purposes)
over the device IP addresses.
