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.

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 .

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.

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.

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 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.

IMPORTANT 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.

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013

System Wiring

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:

• 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.

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.

Chapter 7 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.

100

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 On subsequent connections to the drive (after the initial download), select Upload.
