5. Connect the CP to Industrial Ethernet via one of the RJ45 jacks.
Note
Operation with security on the external network
Make sure that the interfaces function correctly if you use the Security function of the CP.
If you use the security function of the CP, only connect the gigabit interface port X1P1 to
the network after the configuration with security enabled has been loaded.
You will find examples of network attachments in the general Part A of this manual /2/
(Page 118).
6. Where necessary, connect other components to the remaining free RJ45 jacks.
Result: The CP is installed in the rack and the interfaces have been networked.
Note
Autocrossing mechanism - effects on the attachments
For small local area networks or for attaching several Ethernet devices, a 4port switch has
been integrated in the CP 4431 Advanced.
With the autocrossing mechanism integrated in the switch, it is possible to use a standard
cable to connect the laptop or 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 69)
• Connecting switches
If you connect further switches, make sure that no ring is formed in the network.
