Chapter 5 Configuring the encoder for your EtherNet/IP network
Assigning the IP Address using BootP/DHCP:
Verify that the encoder’s MAC ID is in the relationship list in the BootP Utility
or DHCP server before attempting to assign the encoder an IP address using this
procedure.
1. Set the three network address switches to 999 and cycle power.
2. Set the three network address switches to 000 and cycle power.
3. The encoder will power up and request an IP address from a BootP/
DHCP server.
4. If the encoder’s MAC ID is in the relationship list, the BootP/DHCP
server will assign the associated IP address to the corresponding MAC ID.

Function
001-254 Sets last octet of the IP address to the value indicated (xxx in 192.168.1.xxx)
888 Restores all factory default settings in the encoder and clearing its IP address
999 Clears the encoder’s IP address
ATTENTION
Disable DHCP after the new network address is set (see next step).
This prevents unexpected resetting of the network address, which could result
in unintended machine motion or loss of process control.
