Installing the Adapter
Chapter 2
1. Remove power from the drive.
2. Use static control precautions.
3. Connect one end of an Ethernet cable to the network.
Examples of different EtherNet/IP network topologies are shown in
Connecting the Ethernet Cable in a Star Topology Network on page 21,
Connecting the Ethernet Cable in a Linear Topology Network on page 21,
and Connecting the Ethernet Cable in a DLR Topology Network on
page 22. For information about linear and device-level ring (DLR)
topologies, see EtherNet/IP Embedded Switch Technology, publication
ENET-AP005.
IMPORTANT
The adapter has EtherNet/IP embedded switch technology, and ENET1 and
ENET2 network ports to connect to a linear or device-level ring (DLR) network
in a single subnet.
You cannot use ENET1 and ENET 2 network ports as two network interface
cards connected to two different subnets.

4. Depending on the network topology, do one of the following:
• Star Network Topology—Route the other end of the Ethernet cable
from the network through the bottom of the drive, and insert its cable
plug into the option module’s ENET1 or ENET2 network port.
• Linear or DLR Network Topology—Route the other end of the
Ethernet cable from the network through the bottom of the first drive,
and insert its cable plug into the option module ENET1 network port.
To connect to the second drive, attach another Ethernet cable between
the first drive’s option module ENET2 network port and the second
drive’s option module ENET1 network port.
To connect additional drives, repeat these daisy-chain connections in
the same way.
Applying Power
ATTENTION: Risk of equipment damage, injury, or death exists. Unpredictable
operation may occur if you fail to verify that parameter settings are compatible
with your application. Verify that settings are compatible with your application
before applying power to the drive.
Apply power to the drive. The adapter receives its power from the drive.
Startup Status Indication
After power has been applied, the status indicators can be viewed on the front of
the drive. When you apply power to the adapter for the first time, the status
indicators should be green after an initialization. If the status indicators go red,
there is a problem. See Troubleshooting on page 115.

Configuring/Verifying Key Drive Parameters
The PowerFlex 525 drive can be separately configured for the control and
Reference functions in various combinations. For example, you could set the
drive to have its control come from a peripheral or terminal block with the
Reference coming from the network. Or you could set the drive to have its
control come from the network with the Reference coming from another
peripheral or terminal block. Or you could set the drive to have both its control
and Reference come from the network.
Configuring the Host parameters can be done using the drive’s keypad, a HIM,
and software such as RSLogix 5000 or Logix Designer, or Connected
Components Workbench. In the following example, the drive will receive the
Logic Command and Reference from the network.
1. Set the value of Host parameter P046 [Start Source 1]
to 4 “Network Opt”.

Setting the Adapter Node
Address
When the Node Address switches (see Setting the Node Address Switches on
page 18) are set to a value other than 001...254 or 888, Device parameter 04 [Net
Addr Sel] determines the source for the adapter node address. By default, the
Node Address switches are set to 999 and Device parameter 04 [Net Addr Sel] is
set to 3 “DHCP”. This combination selects a DHCP server as the source for the
node address. To use a BOOTP or DHCP server to set the node address, see
Using a BOOTP or DHCP Server on page 28. To use adapter parameters, see
Using Adapter Parameters on page 31.

Configuring the I/O
6. Verify that your computer recognizes the drive. Select Communications >
RSWho and, in the menu tree, click the “+” symbol next to the Ethernet
driver.
7. Note that two other RSLinx drivers (Ethernet devices or Remote Devices
through Linx Gateway) may be used. Use one of these drivers if the
“EtherNet/IP Driver” cannot see your drive.
CompactLogix Example
After the adapter is configured, the drive and adapter will be a single node on the
network. This section provides the steps needed to configure a simple EtherNet/
IP network. In our example, we will configure a 1769-L36ERM CompactLogix
controller with embedded EtherNet/IP capability to communicate with a drive
using Logic Command/Status, Reference/Feedback, and eight Datalinks (four to
read and four to write) over the network.

Chapter 5
Using the I/O
Understanding the I/O Image
The terms input and output are defined from the controller’s point of view.
Therefore, output I/O is data that is produced by the controller and consumed by
the adapter. Input I/O is data that is produced by the adapter and consumed as
input by the controller. The I/O image will vary based on:
• How many of the drive’s 16-bit Datalinks (Host parameters C161 [Opt
Data In 1] through C164 [Opt Data In 4] and C165 [Opt Data Out 1]
through C168 [Opt Data Out 4]) are used.
Device parameters 02 [DLs From Net Act] and 03 [DLs To Net Act]
must also be configured accordingly if Datalinks are used.
• ControlLogix/CompactLogix Controllers only—The drive Add-On
Profile (AOP) used in RSLogix 5000 (version 17 or greater) or Logix
Designer (version 21 or greater) software, or the Generic Profile (all
versions).
• If Multi-drive mode is enabled, and the number of daisy-chained drives
that are present.
I/O Controller Image
Since the drive Add-On Profile in RSLogix 5000 (version 17 or greater) and
Logix Designer (version 21 or greater) software provides descriptive controller
tags, the I/O image (tag size and location) is automatically configured based on
the drive being used. When using the Generic Profile in RSLogix 5000 or Logix
Designer, however, controller tags are not descriptive.
I/O Image for PowerFlex 525 Drives on page 64 shows the I/O image when using
all of the 16-bit Datalinks.

ATTENTION: On PowerFlex 525 drives, support for multi-drive mode using the
25-COMM-E2P Dual-Port adapter is only available on firmware revision 1.004
and later.
ATTENTION: Risk of injury or equipment damage exists. The examples in this
publication are intended solely for purposes of example. There are many
variables and requirements with any application. Rockwell Automation, Inc.
does not assume responsibility or liability (to include intellectual property
liability) for actual use of the examples shown in this publication.
Single-Drive Mode vs.
Multi-Drive Mode
Single-drive mode is a typical network installation, where a single EtherNet/IP
node consists of a single drive with an EtherNet/IP adapter.

EtherNet/IP
Multi-drive mode is an alternative to the typical network installation, where a
single EtherNet/IP node can consist of one to five drives (see Multi-Drive Mode
Example for Network on page 88). The first drive must be a PowerFlex 520-series
drive. The remaining drives can be any PowerFlex drive which supports Multidrive mode.
For the examples in the chapter, we will use the PowerFlex 525 as a master
drive with four daisy-chained PowerFlex 4M drives.

Benefits of Multi-drive mode include:
• Lower hardware costs. No need to purchase additional communication
adapters for daisy-chained drives.
• Reduces the network node count. For example, in Single-drive mode 30
drives would consume 30 nodes. In Multi-drive mode, 30 drives can be
connected in 6 nodes.
• Controller can control, monitor, and read/write parameters for all five
drives.
The trade-offs of Multi-drive mode include:
• If the PowerFlex 520-series drive with Dual-port EtherNet/IP adapter is
powered down, then communications with the daisy-chained drives is
disrupted and the drives will take the appropriate communications loss
action set in each drive.

Using Multi-Drive Mode
Chapter 7
• Communications throughput to the daisy-chained drives will be slower
than if each drive was a separate node on EtherNet/IP (Single-drive
mode). This is because the Dual-port EtherNet/IP adapter must take the
EtherNet/IP data for the other drives and sequentially send the respective
data to each drive over RS-485. The approximate additional throughput
time for Logic Command/Reference to be transmitted and received by
each drive is:

PowerFlex 525 plus 1 drive
PowerFlex 525 plus 2 drives
PowerFlex 525 plus 3 drives
PowerFlex 525 plus 4 drives
• Since the RS-485 ports are used for daisy-chaining the drives, there is no
connection for a peripheral device such as a HIM or USB converter
module (1203-USB). DSI Splitter cables cannot be used to add a second
connection for a peripheral device.
System Wiring
To daisy-chain the drives to the PowerFlex 525, the AK-U0-RJ45-TB2P terminal
block connector can be used for easy installation.
The wiring diagram for using AK-U0-RJ45-TB2P terminal block connectors is
shown below.

Using Multi-Drive Mode
Correlating the Drive with the Controller
You must now correlate the drive settings to the RSLogix 5000 or Logix Designer
project I/O settings so that they match. This requires loading the project I/O
settings into the drive.
1. In the treeview under I/O Configuration, right-click on the drive profile
(for this example “Multi-Drive-25-COMM-E2P
PowerFlex_52X_Drive_Multi”) and select Properties.
2. Select the Drive tab to begin the correlation process.
After the drive configuration data has been verified, the Drive tab will
display a request to synchronize the configuration with the drive. Click
Upload. The correlation process will continue. This may take several
minutes depending on the number and type of daisy-chained drives.
If the Differences Found Screen on page 101 appears—which is typical,
click Download. This will download the project settings from the
controller to the drives. If Upload is clicked, the drive settings are
uploaded to the controller.
TIP
100
On subsequent connections to the drive (after the initial download),
select Upload.
