Product overview
2.3 Hardware properties
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).
