Appendix H
EtherNet/IP
This section contains only basic information to setup an EtherNet/IP
connection with your PowerFlex 520-series drive. For comprehensive
information about
EtherNet/IP (single and dual-port) and how to use it, see the following
publications:
• PowerFlex 525 Embedded EtherNet/IP Adapter User Manual, publication
520COM-UM001
.
• PowerFlex 25-COMM-E2P Dual-Port EtherNet/IP Adapter User Manual,
publication 520COM-UM003
.
It is recommended to use Allen-Bradley Ethernet RJ45 cables, shielded or
unshielded (catalog number 1585J-M8xBJM-x), for connecting your
PowerFlex 520-series drive to an EtherNet/IP network.
Establishing A Connection
With EtherNet/IP
There are three methods for configuring the Ethernet IP address:
• BootP Server – Use BootP if you prefer to control the IP addresses of
devices using a server. The IP address, subnet mask, and gateway
addresses will then be provided by the BootP server.
• 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. The IP address, subnet mask, and
gateway addresses will then come from the adapter parameters you set.
• DHCP (Dynamic Host Configuration Protocol) (only with PowerFlex 25-
COMM-E2P adapter) – Use DHCP 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.
ATTENTION: PowerFlex 523 drives support only the 25-COMM-E2P dual-port
EtherNet/IP adapter. PowerFlex 525 drives support both the embedded
EtherNet/IP adapter and the 25-COMM-E2P dual-port EtherNet/IP adapter.
IMPORTANT
If you are setting your network addresses manually using parameters,
you must set the appropriate drive or 25-COMM-E2P adapter parameter
value to 1 “Parameters”. See the respective EtherNet/IP adapter user
manual for more information.
IMPORTANT
Regardless of the method used to set the adapter IP address, each node
on the EtherNet/IP 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 adapter.
