Omron GI-S Series How To Configure page 2

Introduction
When you add a GI-S to a network there are three ways to set the default IP address so you can
program the I/O Block.
1) Rotary switches
• Will set the IP address to 192.168.250.x. To do this set the rotary switches to 0xx where xx is the last octet in the
IP address.
2) DHCP
• Set the rotary switches to 000 or 400 (400 if you suspect the unit has an existing programmed IP address)
• Cycle power to the GI-S and it will pick up an address from the switch DHCP (if enabled on the switch)
• Use the switch software to determine what IP address the DHCP software on the switch gave to your device.
3) BOOTP-DHCP
• This is a Rockwell Automation tool that lets you assign a specific IP address to a specific MAC address.
• Set the rotary switches to 000 or 400 (400 if you suspect the unit has an exiting programmed IP address)
Note:
When you program the I/O block using Sysmac Studio you will set the device to a fixed IP address
as part of the setup and the DHCP or BOOTP-DHCP servers will no longer be needed. There is no
way to use Sysmac Studio to set the GI-S IP address without a Safety Controller being connected.
Hence the need for DHCP to get the GI-S on the same network as the Safety Controller.
