Interface description
7.3 Ethernet
Table 7-5
B = Bidirectional
Note
The PROFINET interface has what is known as autocrossing functionality, i.e. when required,
transmit and receive lines are switched over. Thus, no crossover cables are necessary.
Cable specification
For PROFINET, you always require a data transmission rate of 100 Mbit/s (Fast Ethernet) in full
duplex mode. For data transfer purposes, you can use twisted-pair copper cables (4-wire,
100Base-T).
