13.1 Troubleshooting
Before contacting Technical Support, you may want to try the following:
 Check to make sure LEDs are not reporting an issue using IO-Link Master LEDs
 Verify that the network IP address, subnet mask, and gateway are correct and appropriate for
the network. Make sure that the IP address programmed into the IO-Link Master matches the
unique reserved IP configured address assigned by the system administrator.
 If using DHCP, the host system needs to provide the subnet mask. The gateway is optional
and is not required for a purely local network.
 Remember that if the rotary switches on the MD 748I-11-42/L5-2222 are set to a non-default
position, the rotary switches override the lower 3 digits (8 bits) of the static IP address
configured in the Network page.
 Verify that the Ethernet hub and any other network devices between the system and the IO-
Link Master are powered up and operating.
 Verify that you are using the correct types of cables on the correct connectors and that all cables
are connected securely.
 Disconnect and re-connect the IO-Link device, or optionally, use the Configuration | IO-Link page
to Reset the port, and then set the Port Mode back to IO-Link.
 Reboot or power cycle the IO-Link Master. Use the Advanced | Software page to reboot the IO-
Link Master.
 Verify that the Port Mode matches the device, for example: IO-Link, Digital In, Digital Out, or
Reset (port is disabled).
 If you are receiving an error that indicates a hardware fault, check the Configuration | IO-Link
page for the port experiencing the fault.
 Check the settings for the Automatic Upload Enable and Automatic Download Enable options.
If the Vendor ID or Device ID of the attached device does not match, a hardware fault is
generated.
 Make sure if the port contains data storage that the Vendor ID and Device ID match the
device attached to the port. If it does not, CLEAR the data storage or move the device to
another port.
 Check the Device Validation and Data Validation settings. If the attached device does not
meet these settings, a hardware fault is issued.
 Open the IO-Link Master web interface and review the following pages to see if you can locate a
problem:
 IO-Link Diagnostics
 Digital I/O Diagnostics
 PROFINET IO
 If you have a spare IO-Link Master, try replacing the IO-Link Master.
