2.1. Setting the Rotary Switch

You can use the rotary switches under the configuration window on the IO-Link Master to set the lower
3digits (8 bits) of the static IP address.

If the rotary switches are set to a non-default position, the upper 9 digits (24 bits) of the IP address are then
taken from the static network address and DHCP maybe disabled. The switches only take effect during
startup, but the current position is always shown on the Help/SUPPORT web page.

Optionally, you can leave the rotary switch set to the default and use the web interface or PortVision DX to set
the network address.

Note: If you set the network address using the rotary switches, the Rotary Switch setting overrides the network

settings in the web interface.

Switch Setting Node Address

Use the network configuration stored in the flash. The default network
configuration values are:

• IP address = 192.168.1.250

000

(Default setting)

Application Base

Corporation's new discovery protocol.

This verifies that a Linux kernel image exists in NAND, then copies it to RAM and
starts the IO-Link Master. The U-Boot version is displayed after the image name.

The FPGA partition/image contains configuration data used by programmable
hardware within the IO-Link Master unit.

The uImage contains the Linux kernel and the RAM-resident root file system. It does
not contain industrial protocol support or application-specific features.

There is a Primary and Backup version loaded on the IO-Link Master. The IO-Link
Master automatically reloads the Backup uImage if the file system corrupted.

The uImage version is displayed after the Primary/Backup uImage.

The Application Base image comprises a flash-resident file system containing
application and protocol support.

The Application Base is built from a collection of application subassemblies -- each of
which may be updated individually between releases of the application base as a
whole.

The application subassemblies in the Application Base image are displayed in the
lower portion of the SOFTWARE web page.

The Application Base assembly has a 2-tuple version number: (for example, 1.10).

4.1.2. Application Subassemblies

Application subassemblies are the components of the Application Base image. Application subassemblies
have 3-tuple or 4-tuple version numbers (for example, 1.10.1). The first two values in a subassembly version
correspond to the version of the application base assembly for which it was built and tested.

For example, a subassembly with version 1.10.3 was tested with application base version 1.10. When using
the SOFTWARE page or PortVision DX, an application subassembly can install only if its version number
matches that of the installed application base assembly. A subassembly with a version of 1.20.2.4 only installs
if the application base version is 1.20. It will not install on a device with application base version 1.09 or 1.20.

This section provides the following information:

• 8.1. Troubleshooting

• 8.2. Contacting Technical Support on Page 58

• 8.3. Using Log Files on Page 59

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 2.5. IO-Link Master LEDs (Page 12)

• 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.
