Manual – MOVI-PLC® advanced DHR41B for EtherNet/IP, Modbus/TCP and PROFINET IO

Setting the IP address parameters

Assembly and Installation Notes for Ethernet

4.8 Setting the IP address parameters

Initial startup The "DHCP" protocol (Dynamic Host Configuration Protocol) is the default setting for the

DHR41B option. This means that the option card expects its IP address parameters from

a DHCP server.

Once the DHCP server has been configured and the settings have been made for the

subnet mask and the standard gateway, the DHR41B option must be added to the as-

signment list of the DHCP server. During this process, the MAC ID of the DHR41B op-

tion is allocated a valid IP address.

Changing the IP

address parame-

ters after initial

startup

If the DHR41B was started using a valid IP address, you can also access the IP address

parameters via the Ethernet interface.

There are various ways to change the IP address parameters via Ethernet:

• Using the MOVITOOLS

MotionStudio software

• Using the EtherNet/IP TCP/IP interface object ( see section 'EtherNet/IP CIP object

directory')

• Using the SEW Address Editor

In addition, you can also change the IP address parameters via the other interface of

DHR41B.

If the IP address parameters are assigned to the option DHR41B via a DHCP server,

you can only change the parameters by adjusting the settings of the DHCP server.

The options listed above for changing the IP address parameters only come into effect

once the supply voltages (DC 24 V) have been switched off and back on again.

TIP

Rockwell Automation provides a DHCP server free-of-charge on their homepage. The

tool is known as "BOOTP Utility" and can be downloaded from the following website:

http://www.ab.com/networks/bootp.html.

TIP

The configured IP address parameters are permanently adopted into the parameter

set if DHCP is deactivated after the IP address has been assigned.
