Setting the IP Address
Switches
There are three methods for configuring the embedded EtherNet/IP
adapter’s IP address:
• Adapter Rotary Switches — Use the switches when working on a
simple, isolated network (for example, 192.168.1.xxx) that has other
products with switches to set their IP addresses, does not need to be
accessed from outside the network, and you prefer a simplified node
addressing method. The three adapter switches are read when the
drive powers up, and represent three decimal digits from top to
bottom (see Figure 2.1
). If set to a valid address (001-254), the
adapter will use that value as the lower octet of its IP address
(192.168.1.xxx, where xxx = rotary switch settings), along with a
subnet mask of 255.255.255.0 and there will be no gateway
configured. Also, the setting for adapter Parameter 36 - [BOOTP]
is automatically ignored.
See Figure 2.1
and its accompanying table for all possible switch
settings and their related descriptions.
Important:When using the adapter rotary switches, set the IP
address before power is applied because the adapter uses
the IP address it detects when it first receives power.
• BOOTP Server — Use BOOTP if you prefer to control the IP
addresses of devices using a server. The IP address, subnet mask,
and gateway addresses will then be provided by the BOOTP server.
• Adapter Parameters — Use adapter parameters when you want
more flexibility in setting up the IP address, or need to communicate
outside the control network using a gateway. The IP address, subnet
mask, and gateway addresses will then come from the adapter
parameters you set.
Important:Regardless of the method used to set the adapter’s IP
address, each node on the EtherNet/IP network must have a
unique IP address. To change an IP address, you must set
the new value and then remove and reapply power to (or
reset) the adapter.
