Automatic setting or individual network settings
As default, the CP is configured for automatic detection (autosensing / autonegotiation /
autocrossing).
Note
In normal situations, the basic setting ensures troublefree communication. You should only
change this in exceptional situations.
If you create a manual configuration for the CP, the automatic negotiation of the network
settings (autonegotiation) is no longer effective. If, on the other hand, the communication
partner works with autonegotiation, no communication will be established.
Only use manual configuration when the communication partner works with the same
manually set configuration.
Autocrossing mechanism
The automatic setting also includes an "autocrossing" mechanism. With autocrossing, you
can connect network components and end devices using either crossover or straight-through
cables.
