The document discusses PROFINET, an industrial Ethernet network standard. It provides an overview of PROFINET features such as using switched Ethernet topology, separate channels for IO data and TCP/IP, and full-duplex communication. It also summarizes the different PROFINET classes (RT, IRT, NRT), how they handle synchronous vs. asynchronous data transmission. The document recommends using a network planning tool to simulate network utilization from PROFINET IO data and other traffic to identify potential overloads and optimize the network design.

PROFINET features
PROFINET is 100% "switched Ethernet“
(no need for repeater)
➔ The topology follows the production process
Device diagnostics & network
diagnostics in all PROFINET devices
➔ Reduction of downtime
Separate channels for IO data and TCP/IP
➔ No extra network for TCP/IP needed
PROFINET uses full duplex communication
➔ More applications on one cable
Two-way simultaneous communication PROFINET uses IT standards (IEEE 802.3)
