LED Diagnosis on the IO-Link Interface

The IO-Link interface monitors the supply voltages for the electronics components and valve control.
If the values fall below a set limit, an event is generated and reported to the IO-Link master. In
addition, the status is displayed by the diagnostic LED.
The LEDs on the top side of the IO-Link interface report the messages listed in Tab. 9.
Before commissioning and during operation, regularly check IO-Link interface functions by
reading the LEDs.

State Meaning
Illuminated The electronics and valve supply voltage is greater than the
lower tolerance limit (21.6 V DC). The communication
connection to the IO-Link master is in the ONLINE operating
state and IO-Link communication has been started.
Flashes The electronics and valve supply voltage is greater than the
lower tolerance limit (21.6 V DC). The communication
connection to the IO-Link master is in the OFFLINE
operating state or IO-Link communication has not been
started.
Alternates The supply voltage to the valves is not switched on. The
communication connection to the IO-Link master is
OFFLINE or the IO-Link communication has not been
started.
Alternates The supply voltage to the valves is not switched on. The
communication connection to the IO-Link master is ONLINE
and IO-Link communication has been started.
Off The supply voltage to the valves is not switched on. The
IO-Link interface is not connected to the master.
