Setup recommendations for optimizing PROFINET
Optimizing PROFINET with RT
PROFINET provides you with high-performance communication on all levels.
The following figures shows an example of an optimized PROFINET topology.
Figure 5-50 Optimized PROFINET topology
When setting up your PN network topology, take care that the various automation
applications are distributed among separate network branches so that a sufficient bandwidth
reserve will be available for future expansions.
● If you integrate standard Ethernet devices into the network topology or use standard
Ethernet communication, take into account the network load caused by standard Ethernet
and adapt the network topology as appropriate (max. bandwidth 100 Mbps).
● For communication with higher-level networks with a high data volume, use the most
direct paths possible to the higher-level network infrastructure.
