Installing the Option Module
This chapter provides instructions for installing the option module in a
PowerFlex 750-Series drive.
Preparing for an Installation Before installing the option module, 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 option module is a multicast device. In most situations, an IGMP
snooping (managed) switch is required. If more than one or two
EtherNet/IP option modules are connected to the switch, a managed
switch is required—otherwise the drive may fault on a Net IO Timeout
network loss. The option module, 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 option modules are set up as unicast devices, then an IGMP snooping
(managed) switch is not needed.
