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)
