table for all possible switch settings and their related descriptions.
• 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. To use parameters as the source for the IP
address, the Node Address switches must be set to a value other than
001...254 or 888, and
Device parameter 04 [Net Addr Sel] must be set to
1“Parameters”. The IP address, subnet mask, and gateway addresses will
then come from the parameters you set. See
for more information.
• BOOTP Server
— Use BOOTP when you want to configure a
temporary
IP address, subnet mask, and gateway address for the adapter using a
BOOTP server. To use BOOTP as the source for the IP address, the Node
Address switches must be set to a value other than 001...254 or 888, and
Device parameter 04 [Net Addr Sel] must be set to 2 “BOOTP”.
Note the adapter’s hardware Ethernet Address (MAC) on the adapter’s
data nameplate label located on the provided control module back cover,
which will be used in Step 7 when configuring the BOOTP server (see
Using a BOOTP or DHCP Server on page 28
for details).
• DHCP (Dynamic Host Configuration Protocol)
— Use DHCP, the
default, when you want additional flexibility and ease-of-use compared to
BOOTP in configuring the IP address, subnet mask, and gateway address
for the adapter using a DHCP server. To use DHCP as the source for the
IP address, the Node Address switches must be set to a value other than
001…254 or 888, and
Device parameter 04 [Net Addr Sel] must be set to 3
“DHCP”.
Note the adapter’s hardware Ethernet Address (MAC) on the adapter’s
data nameplate label located on the provided control module back cover,
which will be used in Step 7 when configuring the DHCP server (see
Using a BOOTP or DHCP Server on page 28
for details).
IMPORTANT
When using the Node Address switches, set the network node address
before power is applied because the adapter uses the node address it
detects when it first receives power.
IMPORTANT
If parameter values are invalid or the adapter was not reset for the
values to take effect, the node address is established by using DHCP.
IMPORTANT
Regardless of the method used to set the adapter’s node address, each node on
the EtherNet/IP network must have a unique IP address. To change a node
address, you must set the new value and then remove and reapply power to (or
reset) the drive.
