IOLM LEDs

14.2.1 IOLM LEDs
The IOLM (8-port IP67 model with an L-coded power connector) provides these LEDs.
LED Activity During Power-On Sequence - IOLM
The US LED lights.
The ETH1/ETH2 LED lights on the connected port.
The MOD and NET LEDs are lit.
The IO-Link LEDs flash (if no IO-Link device is attached) or are lit if an IO-Link device is
attached.
If a PLC is connected, the NET LED is lit and green.

The US LED provides the following information:
Green solid = The IO-Link Master is powered.
Red solid = Power input voltage below 18VDC.
The UA LED provides the following information:
Green solid = The IO-Link Master is powered.
Red solid = Power input voltage below 18VDC.
The MOD LED provides the following information:
Off = No errors or there is no PLC connection
Green and red flashing = Self-test
Green flashing = Standby – not configured
Green solid = Operational
Red flashing:
One or more errors detected when NET is off
Fatal error when NET is also flashing
Red solid = Maintenance required or demanded
The NET LED provides the following information:
Off = No PLC connection
Green and red flashing = Self-test
Green flashing = An IP address is configured, but no connections are
established
Green solid = PLC connection established
Red flashing = Fatal error when MOD is also flashing
Red solid = Duplicate IP address on a network
This LED provides the following information about the IO-Link port.
Off = SIO mode - signal is low or disabled
Yellow = SIO mode - signal is high
Red flashing = Hardware fault - make sure that configured IO-Link settings on
the port do not conflict with the device that is attached:
Automatic Upload and/or Download is enabled and it is not the same device.
Device Validation Mode is enabled and it is not the correct device.
Data Validation Mode is enabled but there is an error.
Solid red = PDI of the attached IO-Link device is invalid.
Green solid = An IO-Link device is connected and communicating
Green flashing = Searching for IO-Link devices
The DI LED indicates digital input on DI (Pin 2).
Of = DI signal is low or disconnected
Yellow = DI signal is high
The ETH1/ETH2 LEDs provide the following information:
Green solid = Link
Green flashing = Activity
