Installing the Adapter
This chapter provides instructions for installing the adapter in a PowerFlex
7-Class drive. The 20-COMM-E Series B adapter, firmware revision 3.xxx
or later, can also be installed in a DPI External Comms Kit. In this case, see
or the 20-XCOMM-DC-BASE Installation Instructions,
publication 20COMM-IN001, supplied with the kit.
Preparing for an Installation
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 18.00 or
later, 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 20-COMM-E adapter is a multicast device. In most situations, an
IGMP snooping (managed) switch is required. If more than one or two
20-COMM-E adapters are connected to the switch, a managed switch is
required—otherwise the drive may fault on a DPI Port x network loss.
The 20-COMM-E Series B adapter, firmware 4.001 or later, RSLogix
5000 software, version 18.00 or later, 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.
