5. Connect the CP to Industrial Ethernet via one of the RJ45 jacks.
You can find examples of network attachments in the general Part A of this manual /2/
(Page 82).
6. Where necessary, connect another component to the remaining free RJ45 jack.
Note
Autocrossing mechanism - effects on the attachments
For small local area networks or for attaching several Ethernet devices, a 2
port switch
has been integrated in the CP
4431.
With the autocrossing mechanism integrated in the switch, it is possible to establish the
connection from a laptop or from the PG/PC directly using standard cables. 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.
You can find more information on this in section Interface configuration (Page 49)
Connecting switches
If you connect further switches, make sure that no ring is formed in the network.
