Interfaces and Connector Assignments
5.5 PORT1, PORT2 - PROFINET IO
An Ethernet-Switch and the Ethernet PHYs are integrated in the ERTEC200.
The PROFINET IO ports PORT1 and PORT2 have got equal rights and no preferred direction.
Figure. 4:
Example for the connection of PROFINET IO-ports
Device connector:
2x RJ45 with integrated transformer and LEDs (yellow/green)

Pin Assignment:
The pin assignment is designed compatible to IEEE 802.3 for 100BASE-TX, RJ45 socket.
NOTICE
Cables of category CAT5 or higher have to be used to grant the function in networks with
100 Mbit/s. esd grants the EC conformity of the product if the wiring is carried out with
shielded twisted pair cables.
