Changing the port properties
The two Ethernet ports of the PROFINET IO interface are set to "Automatic setup" by
default. Observe the following for this default setup:
•
Auto-negotiation and auto-crossover are activated in this setup.
•
Baud rate and duplex mode are configured automatically.
•
The neighboring port must also be set to "Automatic setup".
•
You can use patch or cross cables.
You can set a port to "100 Mbit/s full duplex". Observe the following for this setup:
•
This setting must also be made for the port of the neighboring device, otherwise
this neighboring port would work with 100 Mbit/s half duplex.
•
If auto-crossover is deactivated, you have to use cross cables.
Proceed as follows to set a port to "100 Mbit/s full duplex":
1. Go to the "Device view" tab of the desired device.
2. Select the Ethernet interface.
3. Switch to the "Properties" > "General" tab.
