IO-Link Port
LEDs
Each IO-Link-port is assigned two LEDs which indicate the operating states.
LED “0” - PIN 4, LED “1” - PIN 2

* SC = Short circuit detection on Pin 1. In this case both LEDs are red.
Diagnostics input
Pin 2 of the I/O port can be configured as a diagnostics channel It behaves like an inverted
input. The 0 V signal is interpreted as 1, the corresponding port LED comes n red and a
diagnostics message is sent over DP-diagnostics.
The optical indicator on the corresponding I/O port allows defective sensors/actuators to be
more easily and quickly localized.
