9.2.1 IP Addressing per Ethernet mode
IP parameter configuration depends on the way the Ethernet interfaces are configured (mode), and the
number and type of connections required in the field. The table below shows several configurations and
the number of IP addresses required per configuration. Ports can be assigned to the same network or to
separate networks. Configure addresses only for those interfaces used. Factory default values are
provided for your reference. IP addresses must be unique for communication with other devices on the
same network. Factory default values are used for initial local access. They need to be replaced by valid
and unique IP addresses once you determine connection topology.

Totalflow devices support automatic and static configuration of IP parameters. The following two sections
discuss these two options.
9.2.2 Dynamic and static addressing
ABB Totalflow devices with Ethernet ports support both dynamic and static IP addressing standard
methods of IP configuration. Select what is appropriate for the field conditions.
Dynamic addressing
A device with an enabled DHCP function automatically configures IP parameters. DHCP requests and
obtains the IP parameters for the unit without manual intervention. This is a good option when the device
can connect to a network that has a DHCP server supplying the IP configuration. Network connections
must be reliable because disconnection or network outages cause the controller to lose its IP
configuration. DHCP-obtained IP addresses are public IP addresses valid for connection to the customer
network.
A public address is an address that is valid for the corporate IP address range assigned to a private
customer network. This does not mean it is accessible from outside the customer network. Well-designed
customer networks protect devices from unauthorized users with the use of firewalls and other methods
implemented throughout the network.
IMPORTANT NOTE: The DHCP capability for dynamic Ethernet parameter configuration is
that of a DHCP client, not a DHCP server. If no DHCP server is available on the corporate
network, a local switch/router that supports DHCP can support dynamic addressing. The
switch/router in this case must support the DHCP server function to provide the IP
parameters when the Totalflow device requests them. To support this scenario, enable the
DHCP server function in the router/network equipment before connecting. DHCP adds
options to automate configuration, but carefully consider the reliability of network
connections and the specific scenarios. ABB recommends static IP addressing to ensure IP
configuration is not affected by failure on the network connection or local router.
