5.2 Node address (Host-ID)
Each EtherNet/IP node is addressed by an 8 bit Node address in an EtherNet/IP
segment. This address has only local significance, i.e. it is unique within an
EtherNet/IP segment. The adjusted Node address corresponds to the Host-ID and is
part of the IP address.
Standard IP address, when switches are active
192.168.1.
<adjusted EtherNet/IP Node address>
Net-ID
Host-ID
Table 1: Construction of the IPv4 address
The Node address is adjusted by means of two HEX rotary switches, which are read-
in only in the POWER-ON momentum. Additional adjustments during operation are
not recognized therefore.
Switch activation
Switch = 0x00 or 0xFF
Configuration from
FLASH or DHCP server
Switch = 0x01 … 0xFF + Config. Control = 0x00 *
Switch active
Table 2: Switch activation
* see Attribute 3, Configuration Control of Object 0xF5, TCP/IP Interface on
Node addresses 1…254 may used for the measuring system.
Figure 3: EtherNet/IP Node address, switch assignment
If the HEX rotary switches are active, the following definitions are valid:
● IP address = 192.168.1.<adjusted Node address>
● Subnet mask = 255.255.255.0
● Default Gateway = 192.168.1.254
Configuration via FLASH or DHCP server, see “Attribute 5, Interface Configuration”
