Chapter 2
Installing the Adapter
Chapter 2 provides instructions for installing the Dual-port EtherNet/IP adapter
in a PowerFlex 520-series drive.
Preparing for Set-Up
Before installing the adapter, do the following:
Make sure the Ethernet switch is the correct type. A “managed” switch that
supports IGMP snooping is usually recommended. An “unmanaged”
switch can be used instead if RSLogix 5000 software (version 18 or
greater) is used and all devices on the network are configured for “unicast”
I/O. For more details, see the following documents:
EtherNet/IP Media Planning and Installation Manual,
ODVA publication 148
EtherNet/IP Network Infrastructure Guidelines,
ODVA publication 35
Ethernet Design Considerations Reference Manual,
publication ENET-RM002
Understand IGMP Snooping/Ethernet Switches
The adapter is a multicast device. In most situations, an IGMP snooping
(managed) switch is required. If more than one or two adapters are
connected to the switch, a managed switch is required—otherwise the
drive may fault on a Net I/O Timeout network loss. The adapter,
RSLogix 5000 (version 18 or greater), Logix Designer (version 21 or
greater), and a ControlLogix or CompactLogix controller will support
unicast. Unicast setup is required when adding the drive to the I/O. When
all adapters are set up as unicast devices, then an IGMP snooping
(managed) switch is not needed.
Much of EtherNet/IP implicit (I/O) messaging uses IP multicast to
distribute I/O control data, which is consistent with the CIP producer/
consumer model. Historically, most switches have treated multicast
packets the same as broadcast packets. That is, all multicast packets are re-
transmitted to all ports.
