6.1 Troubleshooting
Before contacting technical support, try the following:
– Check to make sure LEDs are not reporting an issue (see Table 6-1 ).
– 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
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.
– Verify that the Ethernet hub and any other network devices between the system
and the IOL MA8 PN DI8 are powered up and operating.
– Verify that the correct types of cables are used on the correct connectors and that all
cables are connected securely.
– Disconnect and re-connect the IO-Link device, or optionally, use the “IO-Link
Configuration” page (see “IO-Link configuration” on page 31 ) to reset the port, and then
set the Port Mode back to IO-Link.
– Reboot or power cycle the IOL MA8 PN DI8. Use the “Firmware” page (see “Firmware”
on page 53 ) to reboot the IOL MA8 PN DI8.
– Verify that the Port Mode matches the device; for example, IO-Link, Digital In, Digital
Out, or Reset (port is disabled).
– If receiving an error that indicates a hardware fault, check the “IO-Link Diagnostics”
page (see “IO-Link diagnostics” on page 19 ) 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 they do 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 interface and review the various Diagnostic pages to locate a
problem.
– If a spare is available, try replacing the IOL MA8 PN DI8.
