TROUBLESHOOTING
This chapter describes error contents that may occur while the IO-Link module is used and how to troubleshoot.
11.1
Checking the LEDs
This section describes how to troubleshoot the system by the LEDs.
When the US LED is on in red or off
When the UA LED is on in red or flashes in red
When the ERR. LED turns on
When the LINK LED is off
When the L ER LED is on in red
Check item Action
Is the sensor or actuator power supply voltage normal? Check the external power supply voltage and installation environment.
Check item Action
Is the sensor or actuator power supply voltage normal? Check the external power supply voltage and installation environment.
Check item Action
Has any error occurred? Identify the error factor of the IO-Link module with the engineering tool to take the
corrective action. (

Codes)
Check item Action
Are Ethernet cables normal? • Check that 1000BASE-T-compliant Ethernet cables are used.
• Check that the station-to-station distance is 100m or less.
• Check that the Ethernet cables are not disconnected.
Do the switching hub and other stations in the system normally
operate? • Check that a 1000BASE-T-compliant switching hub is used. (

the master/local module used)
• Check that the power supplies of the switching hub and other stations are turned on.
Check item Action
Does the own station in network operate normally? Connect the engineering tool to the master station, and then check that a data link is
established in the own station by using CC IE Field diagnostics. (

Is there any noise affecting the system? • Check the status of wiring.
• When wiring, avoid installing the IO-Link cable or Ethernet cable together with the
main circuit lines or power cables, and avoid placing those cables in close proximity
to each other.
• Connect surge absorbers to noise-generating devices such as relays and
conductors using the same power supply or take other noise reduction measures.
Is the unit test normal? (
