Integrated interfaces for communication

The table below provides an overview of CPU communication options in the S7‑1500R/H
redundant system.
Table 4-6 S7-1500R/H communication options
Communication option
PROFINET IO
MRP (Media Redundancy Protocol)
LLDP (network topology detection)
PG communication for commissioning, testing
and diagnostics
HMI communication for operator control and
monitoring
Open User Communication
S7 communication as server
S7 routing
IP forwarding
Time synchronization
Not with CPU 1513R-1 PN
1)
Not with CPU 1513R-1 PN, CPU 1515R-2 PN and CPU 1517H-3 PN
2)
3) 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.
Reference
For more information on communication options, please refer to the Communication
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.
