Property
Operation of the CPUs
as IO controllers
Note
PROFINET basic functionality
CPU 1513R-1 PN has a PROFINET IO interface with two ports (X1 P1 R and X1 P2 R).
To connect an HMI device or PG/PC to the CPUs via Industrial Ethernet, build the PROFINET
ring via the PROFINET X1 interface. Install a switch in the PROFINET ring. Make an Industrial
Ethernet connection via the switch.
H-Sync Forwarding
H-Sync Forwarding enables a PROFINET device with MRP to forward synchronization data
(synchronization frames) of an S7-1500R redundant system only within the PROFINET ring.
In addition, H-Sync Forwarding forwards the synchronization data even during
reconfiguration of the PROFINET ring. H-Sync Forwarding avoids a cycle time increase if the
PROFINET ring is interrupted.
Note
Support of H-Sync Forwarding
The technical specifications typically state whether a PROFINET device supports
H-Sync Forwarding.
The GSD file will also indicate whether the device supports H-Sync Forwarding. The device
supports H-Sync Forwarding when the "ApplicationClass" attribute contains the
"HighAvailability" token.
You will find more information on H-Sync Forwarding in the system manual S7-1500R/H
redundant system (https://support.industry.siemens.com/cs/ww/en/view/109754833).
Accessories
You can find information on the topic of "Accessories/spare parts" in the system manual for
Redundant System S7-1500R/H

Description
IO controller:
As IO controllers the CPUs address the following configured
IO devices:
•
IO devices with S2 system redundancy within the
PROFINET ring
•
IO devices with S2 system redundancy that are decou-
pled from the PROFINET ring via a switch
•
Standard IO devices (switched S1 devices)
Standard IO devices usually do not support H-
Sync Forwarding.
To avoid a cycle time increase when the PROFINET ring
is interrupted, integrate the standard IO devices behind
a switch and not in the PROFINET ring.
