LEDs of the RJ45 Terminals – Integrated Ethernet Interface (Port J)
The light-emitting diodes (LEDs) signal the operating state of the communication link. The operating states are
explained in the following table:
Integrated Ethernet

LED 1
LED 2
Ethernet COM Link (Port K) (Available only for Modular Devices)
The Ethernet connection to the CB202 PCB assembly (plug-in module assembly with integrated power supply)
is realized using the RJ45 interface.
The RJ45 interface can be used exclusively for the connection of the CB202 module. This terminal is left
unused when no CB202 module is in use.
The light-emitting diodes (LEDs) signal the operating state of the communication connection. The operating
states are explained in the following table:
