Note
Autocrossing mechanism - effects on the connectors
For small local area networks or for attaching several Ethernet devices, a 2
port switch
has been integrated
on the PROFINET interface of the CP.
With the autocrossing mechanism integrated in the switch, it is possible to use a standard
cable to connect the PG/PC. A crossover cable is not necessary.
Please note the following points:
•
Manual configuration
If a port is set to manual configuration and autonegotiation is disabled, the
autocrossing mechanism is also disabled for this port. Which cable you need to use
depends on the partner device (network component or end device).
In the factory, the ports are set for automatic configuration.
For more information, refer to section Network settings (Page 47)
•
Connecting switches
If you connect further switches, make sure that no ring is formed in the network.
