How to eliminate traffic of PROFINET?
PROFINET is based on standard Ethernet. PROFINET frames are transmitted in parallel to TCP/IP frames. This is known as coexistence.
PROFINET ensures deterministic data exchange via various mechanisms that are generally supported by all current Ethernet nodes (bridges/switches). These include the priority contained in the VLAN tag (PCP=6). The state machine of the PROFINET protocol (provider/consumer) also ensures that the connection is stable and that the packets arrive within a predefined time (= watchdog time). PROFINET traffic therefore does not have to be eliminated.
