Pin assignment
For diagnostic purposes, the RJ45 sockets are each equipped with a green and an orange LED.
This allows the following status information about the respective PROFINET port to be
displayed:
Table 8-6
Signal type: O = Output; I = Input
Table 8-7
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.
