Chapter 2 Setting Up the Adapter
IGMP snooping constrains the flooding of multicast traffic by dynamically
configuring switch ports so that multicast traffic is forwarded only to ports
associated with a particular IP multicast group.
Switches that support IGMP snooping (managed switches) “learn” which
ports have devices that are part of a particular multicast group and only
forward the multicast packets to the ports that are part of the multicast
group.
Be careful as to what level of support a switch has of IGMP snooping.
Some layer 2 switches that support IGMP snooping require a router
(which could be a layer 3 switch) to send out IGMP polls to learn what
devices are part of the multicast group. Some layer 2 switches can use
IGMP snooping without a router sending polls. If your control system is a
stand-alone network or is required to continue performing if the router is
out of service, make sure the switch you are using supports IGMP
snooping without a router being present.
• See Appendix A for the number of CIP connections supported by the
embedded EtherNet/IP adapter.
• Verify that you have all required equipment. See Required Equipment on
page 12 .
Setting the IP Address There are two methods for configuring the embedded EtherNet/IP adapter’s IP
address:
• BOOTP Server – Use BOOTP if you prefer to control the IP addresses of
devices using a BOOTP server. The IP address, subnet mask, and gateway
addresses will then be provided by the BOOTP server. This is enabled by
default.
• Parameters – Use 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 parameters you set.
Connecting the Adapter to
the Network
1. Remove power from the drive.
2. Remove the drive control module cover.
IMPORTANT Regardless of the method used to set the adapter’s IP address, each node on
the 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 drive.
ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain
high voltages that can cause injury or death. Remove power from the drive, and
then verify power has been discharged before connecting the embedded
EtherNet/IP adapter to the network.
