Comtrol IO-Link Master Initial Installation and Configuration
IOLM 4-EIP (IP67)
The following procedures discuss connecting the IOLM 4-EIP power and network.
Setting the Rotary Switch
You can use the rotary switches under the configuration window on the IOLM 4-EIP to set the lower 3-
digits (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. The current position displays in 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.
000
(Default setting)
Use the network configuration stored in the flash. The default network values are:
•IP address = 192.168.1.250
•Subnet mask = 255.255.255.0
•IP gateway = 0.0.0.0
001-254 This is the last three digits in the IP address. This uses the first three numbers
from the configured static address, which defaults to 192.168.1.xxx.
255-887 Reserved.
888 Reset to factory defaults.
889-997 Use the network configuration values stored in the flash (reserved).
998 Use DHCP addressing.
999 Use the default IP address.
Use the following steps if you want to change the default rotary switch settings.
1. Remove the two Phillips screws securing the switch window.
2. Gently swing open the switch window from the left to the right, allowing it to pivot on the hinge on
the right side.
3. Turn each dial to the appropriate position using a small
flathead screwdriver.
The default setting is 000 as shown.
The arrow points to the switch location. 0 is located at the
3:00 position. Turn the dial clockwise to the appropriate setting.
4. Carefully close the window making sure that it is properly aligned.
5. Reinsert and hand tighten the two screws making sure that the window is securely sealed.
Note: Failure to reassemble the configuration window properly may compromise IP67 integrity.
