Application planning
6.7 Using HMI devices
S7-1500R/H redundant system
230 System Manual, 01/2024, A5E41814787-AF
Integrate a switch into the PROFINET ring to connect an HMI device to the PROFINET ring. Use
this to establish a connection to the HMI device.
The PROFINET ring is set up using the PROFINET IO interfaces (X1) of the CPUs. If you operate
HMI devices within the ring, you need to assign the MRP role "Client" to the MRP domain. You
can find more information on HMI device application planning in the section Requirements
(Page 129).
Connecting the HMI device to a line topology
To connect an HMI device to a line topology, also connect the HMI device to the line topology
via a switch. Assign the MRP role "Not device in the ring" for the HMI device.
You can find more information on the interfaces of the CPUs 1518HF-
4 PN/1517H-3 PN/1515R-2 PN in the relevant equipment manual.
Connecting HMI devices over Industrial Ethernet, example with CPU 1513R-1 PN
The figure below shows how to connect an HMI device over Industrial Ethernet with the
CPU 1513R-1 PN.
Figure 6-64 Configuration example CPU 1513R-1 PN: Connecting the HMI device via a switch
CPU 1513R-1 PN has a PROFINET IO interface with 2 ports (X1 P1R R and X1 P2R).
To connect an HMI device to the CPUs over Industrial Ethernet, you set up the PROFINET ring
over PROFINET interface X1. Integrate a switch into the PROFINET ring. Use this to establish
an Industrial Ethernet connection.
You can find additional information on the interfaces of CPU 1513R-1 PN in the relevant
device manual.
