8.1. Troubleshooting
Before contacting Technical Support, you may want to try the following:
•
Open the IO-Link Master web interface and review the following web pages:
-
IO-Link Diagnostics
-
EtherNet/IP Diagnostics
-
Modbus/TCP Diagnostics
•
Reboot the IO-Link Master
•
Verify that you are using the correct types of cables on the correct connectors and that all cables are
connected securely.
•
Check to make sure LEDs are not reporting an issue using the IO-Link Master EIP4 User Guide
•
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 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 or in PortVision DX.
•
Verify that the Ethernet hub and any other network devices between the system and the IO-Link Master
are powered up and operating.
•
If you have a spare IO-Link Master, try replacing the IO-Link Master.
