DHCP
The EtherNet/IP communication supports DHCP for easier
network configuration. Dynamic Host Configuration Protocol
(DHCP) is a network protocol that is used to configure
network devices so that they can communicate on an IP
network. As a DHCP client, the EtherNet/IP negotiates with
the DHCP server to determine its IP address and obtain
any other initial configuration details it needs for network
operation.
IP address
IP is divided into four parts. (Part = Octet) Default Static
IP Address is 192.168.1.254
Communication timeout
Defines how much time can pass from the last received
message from the client device before fieldbus fault is
generated. Default communication timeout is 10 seconds.
ote: N If the network cable is broken from the EtherNet/IP
port, a fieldbus error is generatedimmediately.
Static IP address
In most cases the user may want to establish a Static
IP Address for the EtherNet/IP based on their network
configuration.
Static IP address default configurations are as defined
in “EtherNet/IP network settings” table, provided in
“Connections and Wiring” section.
The user can manually define the network address for the
EtherNet/IP as long as all units connected to the network
are given the same network portion of the address. In these
situations, the user will need to manually set the IP Address
in the device by using the drive keypad. Be aware that
overlapping IP addresses can cause conflicts between devices
on the network. For more information about selecting IP
addresses, contact your networkadministrator.
Unit identifier
The Unit Identifier used in Modbus TCP is used for the
Modbus protocol in place of the slave address used in
Modbus RTU. This Unit Identifier is used to communicate
via devices such as bridges, routers and gateways that use
a single IP address to support multiple independent Modbus
end units.
