Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 9

Chapter 1 Getting Started

Features

The features of the Dual-port EtherNet/IP adapter include:

• Industrial Ethernet switch, and ENET1 and ENET2 network ports that provide connections for EtherNet/IP star, linear, or device-level ring (DLR) network topologies.

• Switches to set a network node address before applying power to the drive—or you can disable the switches and use a BOOTP server, a Dynamic Host Configuration Protocol (DHCP) server, or adapter parameters to configure the IP address.

• Compatibility with various configuration tools to configure the adapter and host drive. The tools include the PowerFlex 4/40-class HIM (Human Interface Module 22-HIM-A3 or 22-HIM-C2S), and drive-configuration software such as RSLogix 5000 (version 17 or greater), Logix Designer (version 21 or greater), and Connected Components Workbench (version 3 or greater).

• Status indicators that report the status of the adapter and network communications.

• Parameter-configured 16-bit Datalinks in the I/O to meet application requirements (four Datalinks to write data from the network to the drive, and four Datalinks to read data to the network from the drive).

• Explicit Messaging support.

• Master-Slave hierarchy that can be configured to transmit data to and from

a controller on the network.

• Multi-drive mode which allows up to five drives to share a single EtherNet/IP node.

• User-defined fault actions to determine how the adapter and its host PowerFlex 520-series drive respond to:

– I/O messaging communication disruptions (Comm Flt Action) – Controllers in idle mode (Idle Flt Action)

• Automatic Device Configuration (ADC) is an RSLogix 5000 (version 20

or greater) and Logix Designer (version 21 or greater) software feature that supports the automatic download of configuration data upon the Logix controller establishing an EtherNet/IP network connection to a PowerFlex 520-series drive and its associated peripherals.

Safety Precautions

Please read the following safety precautions carefully.

ATT EN TI ON : Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death. Remove all power from the PowerFlex drive, and then verify power has been removed before installing or removing an adapter.

ATT EN TI ON : Risk of injury or equipment damage exists. Only personnel familiar with drive and power products and the associated machinery should plan or implement the installation, start up, configuration, and subsequent maintenance of the drive using this Dual-port EtherNet/IP adapter. Failure to comply may result in injury and/or equipment damage.

ATT EN TI ON : Risk of equipment damage exists. The adapter contains ESD (Electrostatic Discharge) sensitive parts that can be damaged if you do not follow ESD control procedures. Static control precautions are required when handling the adapter. If you are unfamiliar with static control procedures, see Guarding Against Electrostatic Damage, publication 8000-4.5.2

ATT EN TI ON : Risk of injury or equipment damage exists. If the adapter is transmitting control I/O to the drive, the drive may fault when you reset the adapter. Determine how your drive will respond before resetting the adapter.

ATT EN TI ON : Risk of injury or equipment damage exists. Device parameters 23 [Comm Flt Action] and 24 [Idle Flt Action] let you determine the action of

the adapter and drive if I/O communication is disrupted, the controller is idle, or explicit messaging for drive control is disrupted. By default, these parameters fault the drive. You may configure these parameters so that the drive continues to run, however, precautions should be taken to ensure that the settings of these parameters do not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable or a controller in idle state).

ATT EN TI ON : Risk of injury or equipment damage exists. When a system is configured for the first time, there may be unintended or incorrect machine motion. Disconnect the motor from the machine or process during initial system testing.

ATT EN TI ON : 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.

Preparing for Set-Up

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 or greater) is used and all devices on the network are configured for “unicast” I/O.

The adapter is a multicast device. In most situations, an IGMP snooping (managed) switch is required. If more than one or two adapters are connected to the switch, a managed switch is required—otherwise the drive may fault on a Net I/O Timeout network loss. The adapter, RSLogix 5000 (version 18 or greater), Logix Designer (version 21 or greater), 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.

Much of EtherNet/IP implicit (I/O) messaging uses IP multicast to distribute I/O control data, which is consistent with the CIP producer/ consumer model. Historically, most switches have treated multicast packets the same as broadcast packets. That is, all multicast packets are retransmitted to all ports.

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 15

Chapter 2 Installing the Adapter

IMPORTANT

IGMP snooping constrains the flooding of multicast traffic by dynamically configuring switch ports so that multicast traffic is forwarded only to ports associated with a particular IP multicast group.

Switches that support IGMP snooping (managed switches) “learn” which ports have devices that are part of a particular multicast group and only forward the multicast packets to the ports that are part of the multicast group.

Be careful as to what level of support a switch has of IGMP snooping. Some layer 2 switches that support IGMP snooping require a router (which could be a layer 3 switch) to send out IGMP polls to learn what devices are part of the multicast group. Some layer 2 switches can use IGMP snooping without a router sending polls. If your control system is a stand-alone network or is required to continue performing if the router is out of service, make sure the switch you are using supports IGMP snooping without a router being present.

• See Specifications

on page 123 for the number of CIP connections

supported by the adapter.

• Verify that you have all required equipment. See Required Equipment

page 11.

Setting the Node Address

ATT EN TI ON : Risk of equipment damage exists. The adapter contains ESD

(Electrostatic Discharge) sensitive parts that can be damaged if you do not follow ESD control procedures. Static control precautions are required when handling the adapter. If you are unfamiliar with static control procedures, see Guarding Against Electrostatic Damage, publication 8000-4.5.2

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.

There are four methods for configuring the adapter’s node address:

• Node Address Switches — Use these switches when working on a simple isolated network (for example, 192.168.1.xxx) that has other products with switches to set their IP addresses, does not need to be accessed from outside the network, and you prefer a simplified node addressing method. The three rotary switches are read when the drive powers up, and represent three decimal digits from top to bottom (see Setting the Node Address

Switches on page 18). When set to a valid address (001...254), the adapter

will use that value as the lower octet of its IP address (192.168.1.xxx, where xxx = rotary switch settings), along with a subnet mask of 255.255.255.0, and a gateway address of 0.0.0.0 when switches are set to 001, or a gateway address of 192.168.1.1 when switches are set from 002...254. Also, the setting for Device parameter 04 [Net Addr Sel] is automatically ignored.

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

Installing the Adapter Chapter 2

IMPORTANT

See Setting the Node Address Switches on page 18 and its accompanying table for all possible switch settings and their related descriptions.

When using the Node Address switches, set the network node address before power is applied because the adapter uses the node address it detects when it first receives power.

•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. To use parameters as the source for the IP address, the Node Address switches must be set to a value other than

001...254 or 888, and Device parameter 04 [Net Addr Sel] must be set to 1“Parameters”. The IP address, subnet mask, and gateway addresses will then come from the parameters you set. See Using Adapter Parameters

page 31for more information.

If parameter values are invalid or the adapter was not reset for the values to take effect, the node address is established by using DHCP.

•BOOTP Server — Use BOOTP when you want to configure a temporary IP address, subnet mask, and gateway address for the adapter using a BOOTP server. To use BOOTP as the source for the IP address, the Node Address switches must be set to a value other than 001...254 or 888, and Device parameter 04 [Net Addr Sel] must be set to 2 “BOOTP”.

Note the adapter’s hardware Ethernet Address (MAC) on the adapter’s data nameplate label located on the provided control module back cover, which will be used in Step 7 when configuring the BOOTP server (see

Using a BOOTP or DHCP Ser ver

on page 28 for details).

• DHCP (Dynamic Host Configuration Protocol) — Use DHCP, the default, 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. To use DHCP as the source for the IP address, the Node Address switches must be set to a value other than 001…254 or 888, and Device parameter 04 [Net Addr Sel] must be set to 3 “DHCP”.

Using a BOOTP or DHCP Ser ver

on page 28 for details).

Regardless of the method used to set the adapter’s node address, each node on the EtherNet/IP network must have a unique IP address. To change a node address, you must set the new value and then remove and reapply power to (or reset) the drive.

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”.

By default, the adapter automatically detects the data (baud) rate and duplex setting used on the network. If you need to set a specific data rate and duplex setting, the value of Device parameters 18 [Net Rate Cfg 1] determines the Ethernet data rate and duplex setting that will be uses to communicate on the adapter’s ENET1 network port. For definitions of data rate and duplex, see the

2. Reset the adapter; see Resetting the Adapter

A hierarchy determines the type of device with which the adapter exchanges data. In a Master-Slave hierarchy, the adapter exchanges data with a master, such as a scanner or bridge.

on page 36.

Configuring a Master-Slave Hierarchy

The controller I/O image can have anywhere from zero to eight (four In and four Out) additional 16-bit parameters called Datalinks. They are configured using

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]. The number of

Datalinks actively used is controlled by the connection size in the controller and the in/out parameters. See the respective controller example sections in

Configuring the I/O

size.

When using a ControlLogix or CompactLogix controller and the Generic Profile, or a MicroLogix 1100/1400 controller, configure the Datalink parameters now as described in this section.

on page 39 for more information on setting the connection

When using a ControlLogix or CompactLogix controller and a drive Add-On Profile for RSLogix 5000 (version 17 or greater) or Logix Designer (version 21 or greater) software, there is no need to configure Datalink parameters at this time. They will be assigned when configuring the drive Add-On Profile (see

Adding the Drive/Adapter to the I/O Configuration

on page 42).

Enabling Datalinks To Write Data

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host parameters C165, C166, and C167 to configure three Datalinks to write data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

Host parameters C165 [Opt Data Out 1] through C168 [Opt Data Out 4] control which parameters in the drive send values to the network. To configure these parameters, set them to the drive parameter number you want to correlate them to.

The following steps are required to enable Datalinks to write data:

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 33

Chapter 3 Configuring the Adapter

IMPORTANT

1. Set the values of only the required number of contiguous drive-to-network Datalinks needed to write data to the network and that are to be included in the network I/O connection.

2. Reset the adapter; see Resetting the Adapter

After the above steps are complete, the adapter is ready to send output data and transfer status data to the master (controller). Next, configure the controller to recognize and transmit I/O to the adapter. See Configuring the I/O

on page 36.

on page 39.

Enabling Datalinks To Read Data

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host parameters C161, C162, and C163 to configure three Datalinks to read data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

Host parameters C161 [Opt Data In 1] through C164 [Opt Data In 4] configure which parameters in the drive receive values from the network. To configure these parameters, set them to the parameter number you wish to correlate them to.

The following steps are required to enable Datalinks to read data:

1. Set the values of only the required number of contiguous network-to-drive Datalinks needed to read data from the network and that are to be included in the network I/O connection.

Setting a Fault Action

2. Reset the adapter; see Resetting the Adapter

After the above steps are complete, the adapter is ready to receive input data from the master (controller). Next, configure the controller to recognize and transmit I/O to the adapter. See Configuring the I/O

By default, when communications are disrupted (the network cable is disconnected) and/or the controller is idle (in program mode or faulted), the drive responds by faulting if it is using I/O from the network. You can configure a different response to these events:

• Disrupted I/O communication by using Device parameter 23 [Comm Flt Action].

on page 36.

on page 39.

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

Configuring the Adapter Chapter 3

• An idle controller by using Device parameter 24 [Idle Flt Action].

ATT EN TI ON : Risk of injury or equipment damage exists. Device parameters 23 [Comm Flt Action] and 24 [Idle Flt Action] respectively let you determine the action of the adapter and drive if communications are disrupted or the controller is idle. By default, these parameters fault the drive. You may configure these parameters so that the drive continues to run, however, precautions should be taken to ensure that the settings of these parameters do not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (a disconnected network cable or controller in idle state).

Changing the Fault Action

Set the values of Device parameters 23 [Comm Flt Action] and 24 [Idle Flt Action] to the desired responses:

Value Action Description

0 Fault The drive is faulted and stopped. Datalink data is no longer sent to the drive. (Default) 1 Stop The drive is stopped as per Host parameter P045 [Stop Mode] setting. Datalink data sent to

2 Zero Data The drive is sent “0” values for all Reference and Datalink data. This does not command a stop. 3 Hold Last The drive continues in its present state. 4 Send Flt Cfg The drive is sent the Reference and Datalink data that you set in the fault configuration

the drive remains unchanged.

parameters (Device parameters 25 [Flt Cfg Logic], 26 [Flt Cfg Ref], and 27 [Flt Cfg DL 1] through 30 [Flt Cfg DL 4]).

Changes to these parameters take effect immediately. A reset is not required. If communication is disrupted and then re-established, the drive will automatically receive commands over the network again.

If Multi-Drive mode is used, the same fault action is used by the adapter for all of the drives it controls (Drive 0...4).

Setting the Fault Configuration Parameters

When setting Device parameters 23 [Comm Flt Action] and 24 [Idle Flt Action] to 4 “Send Flt Cfg,” the values in the following parameters are sent to the

drive after a communications fault and/or idle fault for drive control fault occurs. You must set these parameters to values required by your application.

Parameter Description

25 [Flt Cfg Logic] A 16-bit integer value sent to the drive for Logic Command. 26 [Flt Cfg Ref] A 16-bit integer value sent to the drive for Reference. 27 [Flt Cfg DL 1] through

30 [Flt Cfg DL 4]

Changes to these parameters take effect immediately. A reset is not required.

IMPORTANT

Resetting the Adapter

Restoring Adapter Parameters to Factory Defaults

Changes to switch settings or some adapter parameters require that you reset the adapter before the new settings take effect. You can reset the adapter by cycling power to the drive or by using Device parameter 22 [Reset Module].

Set Device parameter 22 [Reset Module] to 1“Reset Module”.

Setting for Device Parameter 22 [Reset Module]

Value Description

0 Ready (Default) 1 Reset Module 2Set Defaults

When you enter 1 “Reset Module”, the adapter will be immediately reset. An alternate method to reset the adapter is by power cycling the drive.

Set Device parameter 22 [Reset Module] to 2 “Set Defaults”.

Setting for Device Parameter 22 [Reset Module]

Value Description

0 Ready (Default) 1 Reset Module 2Set Defaults

When you enter 2 “Set Defaults”, the adapter will set all of its parameters to their factory default values.

When performing a Set Defaults action, the drive may detect a conflict and then not allow this function to occur. If this happens, first resolve the conflict and then repeat a Set Defaults action. Common reasons for a conflict include the drive running or a controller in Run mode.

After performing a Set Defaults action, you must enter 1 “Reset Module” or power cycle the drive so that the new values take effect. Thereafter, this parameter will be restored to a value of 0 “Ready”.

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.

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

Adding the Controller to the I/O Configuration

To establish communications between the controller and adapter over the network, you must first add the CompactLogix controller and its embedded EtherNet/IP bridge to the I/O configuration.

Configuring the I/O Chapter 4

1. Start RSLogix 5000 or Logix Designer. The application window appears. Select File > New to display the New Controller window.

Select the appropriate choices for the fields in the window to match your application. Then click OK. The application window reappears with the treeview in the left pane.

Note : If you are using a controller without an embedded EtherNet/IP bridge, you will also need to add the bridge to the I/O configuration. See the user manual for your controller for details.

2. Configure the IP address/Network Settings on your controller or bridge. In this example, the Network Settings are set for a private network.

3. Click OK. The controller is now configured for the EtherNet/IP network. It appears in the I/O Configuration folder. In our example, a 1769-L36ERM controller appears under the I/O Configuration folder with its assigned name.

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 41

Chapter 4 Configuring the I/O

There are two ways to add the adapter into the I/O configuration:

• Drive Add-On Profiles (for RSLogix 5000 version 17 or greater, Logix Designer version 21 or greater)

• Generic Profile (for RSLogix 5000 or Logix Designer, all versions)

These are described in the following separate sections. If your version of RSLogix 5000 or Logix Designer software supports drive Add-On Profiles, we recommend using this method.

Using Drive AOP (Add-On Profiles) with RSLogix 5000 or Logix Designer

When using the drive Add-On Profiles (with RSLogix 5000 vesion 17 or greater, or Logix Designer version 21 or greater) compared to the Generic Profile (all versions), the drive Add-On Profiles provide these advantages:

• Profiles for specific drives that provide descriptive controller tags for basic control I/O words (Logic Command/Status and Reference/Feedback) and Datalinks. Additionally, Datalinks automatically take the name of the drive parameter to which they are assigned. These profiles virtually eliminate I/O mismatch errors and substantially reduce drive configuration time.

• New Drive tab eliminates the need for a separate drive software configuration tool.

• Drive configuration settings are saved as part of the RSLogix 5000 or Logix Designer project file (.ACD) and also downloaded to the controller.

• Drive Add-On Profiles can be updated anytime. When a new drive is used or to benefit from new updates for Add-On Profiles, you will need the newest Add-On Profile update. Go to www.ab.com/support/abdrives/

webupdate to download the latest RSLogix 5000 or Logix Designer drive

Add-On Profile.

Adding the Drive/Adapter to the I/O Configuration

To transmit data between the controller and the drive, you must add the drive as a child device to the parent controller. In this example, RSLogix 5000 software version 20 is used with drive Add-On Profile version 1.02.

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 45

Chapter 4 Configuring the I/O

IMPORTANT

When using Datalinks you must still assign 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] to point to the appropriate drive or connected peripheral parameters. The procedure to configure the Datalinks on the Module Definition window for the Input Data and Output Data is the same:

• Click the button to assign a parameter to each input and output Datalink you require.

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. (For example, use parameters C161, C162, and C163 to configure three Datalinks to write data and/or parameters C165, C166, C167, and C168 to configure four Datalinks to read data.) Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

6. Click OK on the Module Definition window to save the drive configuration and close the window. The drive’s New Module window reappears.

7. On the New Module window, click the Connection tab.

8. In the “Requested Packet Interval (RPI)” box, set the value to 2.0

milliseconds or greater. This value determines the maximum interval that a controller should use to move data to and from the adapter. To conserve bandwidth, use higher values for communicating with low priority devices.

The “Inhibit Module” box, when checked, inhibits the module from communicating with the RSLogix 5000 or Logix Designer project. When the “Major Fault On…” box is checked, a major controller fault will occur when the module’s connection fails while the controller is in the Run Mode. For this example, leave the “Inhibit Module” and “Major Fault On…” boxes unchecked.

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

Configuring the I/O Chapter 4

The “Use Unicast Connection over EtherNet/IP” box is checked by default. This is the recommended setting. When this box is unchecked, the adapter will send multicast messages on the I/O connection. In this case, the adapter and the EtherNet/IP bridge must be on the same subnet.

9. Click OK on the New Module window. The new node (“PowerFlex 525-E2P PowerFlex_52X_Drive” in this

example) now appears under the icon in the I/O Configuration folder. If you double-click on the Input Controller Tag (see Controller

an EtherNet/IP network connection to a PowerFlex 525 drive and its associated peripherals.

• ADC is not available for DSI peripherals.

• ADC is not available in Multi-drive mode.

• ADC is only available when the drive is connected using the Dual-port

EtherNet/IP adapter to a compatible controller.

An RSLogix 5000 (version 20) or Logix Designer (version 21 or greater) project (.ACD file) contains the configuration settings for any PowerFlex drives in the project. When the project is downloaded to the Logix controller, these settings are also transferred and reside in the controller’s memory. Prior to ADC in RSLogix 5000 (version 20) or Logix Designer (version 21 or greater), downloading PowerFlex 525 configuration data was a manual process where the user would open the Drive tab in the respective drive Add-On Profile (AOP) in the application and click on the Download icon. ADC now automates the process and saves the user time. It is particularly beneficial in a drive replacement situation when a production line is down.

ADC can also work in tandem with Firmware Supervisor. If Firmware Supervisor is set up and enabled for a drive (“Exact Match” keying must be used), the drive/ peripheral will be automatically flashed (if necessary) prior to any ADC operation.

Logix “owns” the configuration of the drive. ADC will be triggered any time the Logix controller detects a configuration signature mismatch when establishing an EtherNet/IP network I/O connection. The use of

other configuration tools, such as a HIM or Connected Components Workbench software should be minimized and restricted to monitor-only operation. Any configuration changes made by these tools will cause a configuration signature mismatch the next time the Logix controller connects to the device and ADC will write over any changes made by the other tool(s). Any drive configuration changes should be made with the drive Add-On Profile.

The drive AOP requires user action to enable ADC. This helps ensure that the user understands ADC operation prior to turning it on. The drive AOPs also have an ADC icon on the Drive tab to show general ADC enable/disable status for the drive:

Icon Meaning

No ports on the drive have ADC enabled.

At least one port on the drive has ADC enabled.

ADC is not supported.

Clicking on the ADC icon will launch the ADC configuration window. This provides a single, convenient location to enable/disable ADC on the drive.

Chapter 4 Configuring the I/O

ADC and Logix Memory

Starting in RSLogix 5000 software version 16, drive configuration settings have been stored in the project's ACD file which is downloaded and stored in the controller. The majority of Logix controllers have megabytes of memory available, so this typically should not be an issue. You can monitor Logix memory usage in the application in the Controller Properties > Memory tab.

Storing the Drive’s and Peripheral’s Firmware in the Logix Controller (Firmware Supervisor)

The Logix Firmware Supervisor function has been extended to provide firmware updates for the peripherals connected to the drive. To configure the controller to check and refresh the correct firmware for the drive and peripherals, perform the following steps:

1. Verify that “Exact Match” keying is selected in the drive’s and peripherals’ properties screens (the drive’s is in the General tab; the peripherals’ are under the Drive tab, after right-clicking on each peripheral and choosing

Properti es).

2. Verify that ControlFlash firmware kits for each revision of firmware for

each device that should be stored in the controller have been installed on the PC running RSLogix 5000 or Logix Designer software.

3. Verify that a CompactFlash or other storage card has been installed in the controller.

4. Use RSLogix 5000 or Logix Designer to go online with the controller in Program mode. Download your program if you have not done so already.

5. In the treeview, right-click on the controller folder at the top of the Controller Organizer and choose Properties . On the Controller Properties window, select the Nonvolatile Memory tab.

IMPORTANT

6. Click Load/Store…. The Nonvolatile Memory Load/Store window appears.

In the Controller section for the Automatic Firmware Update field, select “Enable and Store Files to Image,” and click the <-- Store button. You may see two different continue confirmation dialog boxes relating to communication disruptions and erasure of the current contents of the storage card. If okay, click Ye s on each dialog box.

7. The application will go to the Offline state, and the following dialog box will appear.

Wait a short period of time for the store operation to complete, and then attempt to go online with the controller again.

Monitoring the ADC Progress

The time it takes for the ADC process to complete will vary from seconds to several minutes depending on several factors:

• The number of peripherals enabled for ADC.

• If a configuration signature for the drive/peripheral indicates a

configuration download needs to be performed for the given port.

• Whether Firmware Supervisor is enabled and needs to flash the drive and/ or any peripherals.

ADC can automatically reset the drive as part of the configuration process. This is done because some parameters require a reset before they take effect. If a drive is being replaced with an out-of-the-box drive, you will typically see one or more resets during the ADC process.

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 55

Chapter 4 Configuring the I/O

An operational drive in a running Logix system will have the following status indicator states:

Status Indicator State Description

PORT Steady Green The adapter is properly connected and is communicating with the drive. MOD Steady G reen The adapter is operating normally and is transferring I/O data to a controller. NET A Steady Green The adapter is operating normally and has at least one CIP connection (I/O or

explicit) .

NET B Flashing Green The adapter is transmitting on the network.

See Understanding the Status Indicators

on page 115 for more information.

Additional information may also be displayed on the HIM if it is present (flash status, etc.).

If ADC is unsuccessful, RSLogix 5000 or Logix Designer software can be used to get additional information. When online, the drive at issue should have a yellow

triangle next to it in the RSLogix 5000 or Logix Designer project's I/O Configuration folder. Double-click on the drive to open the drive AOP. The Connection tab will show a Module Fault code and the Drive tab can help you identify issues.

Examples of potential issues/solutions are:

Issue Solution

“Compatible module” keying selected, but replacement drive or peripheral has an earlier firmware revision than the failed device.

Peripheral is required for connection (“Fail Drive Connection on Peripheral Error” was checked), but it is missing.

Parameter “out of range” error—ADC wrote a value to a parameter that was out of range (typically would only occur during initial commissioning of a drive system).

Replace device with a revision that is later than or equal to the failed device. If necessar y, use ControlFLASH to flash replacement device first to an acceptable revision level.

Add required peripheral or remove peripheral from RSLogix 5000/Logix Designer project for the drive and download project to the controller.

Use any available drive software tool to view a linear list of changed parameters to see if the configured value is outside the minimum/maximum value. The drive AOPs are the preferred tool and will highlight any out of range parameter in the Linear List editor. Connected Components Workbench (version 3 or greater) may also be used.

Using the RSLogix 5000 or Logix Designer Generic Profile

The basic RSLogix 5000 (all versions) or Logix Designer (version 21 or greater) Generic Profile is only recommended when:

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

Configuring the I/O Chapter 4

• A specific drive profile in other versions of RSLogix 5000 or Logix Designer software is unavailable.

• Users are already familiar with a Generic Profile and do not want to convert an existing project to a drive Add-On Profile (RSLogix 5000 version 17 or greater and Logix Designer version 21 or greater).

• A project must maintain specific revision level control.

• The controller cannot be taken offline. RSLogix 5000 (all versions) and

Logix Designer (version 21 or greater) software enables the drive Generic Profile to be added while the controller is online and in the Run mode.

Adding the Drive/Adapter to the I/O Configuration

To transmit data between the bridge and the drive, you must add the drive as a child device to the parent bridge.

1. In the treeview, right-click on the icon and select New Module… to display the Select Module Type window. Expand the

Communications group to display all of the available communication modules or search for “ETHERNET-MODULE”.

2. Select “ETHERNET-MODULE” from the list in the Select Module Type window to configure the drive’s embedded EtherNet/IP adapter, and then click Create. The drive’s New Module window appears.

parameters [Opt Data Out x] used for your application, either in Single-drive mode (see details below) or Multidrive mode (see Using Multi-Drive Mode

on page 87).

Enter the number of 16-bit words that are required for your I/O in the Input Size and Output Size boxes. Since the adapter always uses the 16-bit Logic Status, 16-bit Feedback, and two 16-bit words dedicated for memory allocation of the Generic Ethernet module profile, at least four 16-bit words must be set for the Input Size. The adapter also uses the 16bit Logic Command and 16-bit Reference, requiring at least two 16-bit words for the Output Size. If any or all of the drive’s eight 16-bit Datalinks are used (see Configuring a Master-Slave Hierarchy

on page 33), the Input

and Output Size settings must be increased accordingly.

TIP

Saving the I/O Configuration to the Controller

After adding the bridge and drive/adapter to the I/O configuration, you must download the configuration to the controller. You should also save the configuration to a file on your computer.

When using RSLogix 5000 or Logix Designer software, you can add the I/O configuration of a Generic Profile while the controller is online and in the Run mode.

1. In the RSLogix 5000 or Logix Designer window, select Communications > Download. The Download dialog box appears.

on page 39 for details.

2. Click Download to download the configuration to the controller. When the download is successfully completed, RSLogix 5000 or Logix Designer goes into the Online mode and the I/O OK box in the upper-left of the screen should be steady green.

3. Select File > Save. If this is the first time you saved the project, the Save As dialog box appears. Navigate to a folder, type a file name, and click Save to save the configuration to a file on your computer.

4. Any Datalinks that were enabled in the controller and drive during I/O configuration must also be configured in the drive. Each Datalink being used must be assigned to a specific parameter in the drive or connected peripheral (see Configuring a Master-Slave Hierarchy

on page 33). If this is

not done, the controller will receive or send placeholder data instead of actual drive or peripheral parameter values.

5. Place the controller in Remote Run or Run Mode.

Chapter 4 Configuring the I/O

Limitations in Using MicroLogix 1100/1400

Controlling I/O with explicit messages is relatively complex compared to normal implicit I/O control.

ControlLogix and CompactLogix controllers with EtherNet/IP provide the easiest and most integrated form of implicit I/O control for a PowerFlex drive. RSLogix 5000 or Logix Designer programming software for ControlLogix and CompactLogix controllers contains integrated profiles for PowerFlex drives that, with a few clicks of the mouse, automatically create all controller tags and an implicit connection at the specified Requested Packet Interval to control the drive. This connection is monitored at both ends to ensure that the controller and drive are communicating. A watchdog will cause a drive fault if the drive does not respond within approximately 100 milliseconds. Therefore, using a ControlLogix or CompactLogix controller is by far the much preferred method of controlling drives on EtherNet/IP.

If you are not using either of these type of controllers, then PowerFlex drives on EtherNet/IP can be controlled with explicit messages using MicroLogix 1100/1400 controllers with the following limitations:

• An explicit message is a much slower form of control and is nondeterministic. This means that you cannot guarantee how long the drive will take to start up or stop when the command is given. Therefore, all equipment used in this manner should be subject to a risk assessment, taking into account the mechanical and electrical implementation.

• A timeout value (in seconds) in the embedded EtherNet/IP adapter will issue a drive fault if a message is not received from the controller within the specified time. However, the controller has no way of detecting a loss of communications to the drive until the next cycle of explicit messages. This is another factor in the risk assessment.

• Any additional drives to be controlled will require additional explicit messages for their control, and they need to be carefully sequenced. Most controllers have small communication queues (see its User Manual), which need to be carefully managed if messages are not to be lost.

• Each controller has a limited number of communication connections (see its User Manual for maximum connections), which will limit the number of drives that can be connected.

In summary, unlike a ControlLogix or CompactLogix controller, programming a MicroLogix 1100/1400 controller using RSLogix 500 software with explicit messages is more difficult, and produces a more complex program.

About I/O Messaging

On CIP-based networks, including EtherNet/IP, I/O connections are used to transfer the data which controls the PowerFlex drive and sets its Reference. I/O can also be used to transfer data to and from Datalinks in PowerFlex 520-series drives.

The adapter includes the Logic Command, Logic Status, Reference, Feedback, and memory allocation for the Generic Ethernet module profile (all as 16-bit words) in the controller’s I/O image. This basic I/O must always be configured in the Ethernet bridge using RSLogix 5000 or Logix Designer software. Additional I/O, if needed, can be set using up to four Datalinks to write data and/or up to four Datalinks to read data. When using any combination of these Datalinks, add one 16-bit word for each Datalink to the basic I/O Input Size and/or Output Size.

Configuring the Adapter

on page 25 and Configuring the I/O on page 39 discuss

how to configure the adapter and controller on the network for the required I/O. The Glossary defines the different options. This chapter discusses how to use I/O after you have configured the drive and controller.

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 63

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.

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

Using the I/O Chapter 5

Using Logic Command/Status

Using Reference/Feedback

The Logic Command is a 16-bit word of control data produced by the controller and consumed by the adapter. The Logic Status is a 16-bit word of status data produced by the adapter and consumed by the controller.

When using a ControlLogix or CompactLogix controller, the Logic Command word is always INT 0 in the output image and the Logic Status word is always:

• INT 0 in the input image when using the drive Add-On Profile.

• INT 2 when using the Generic Profile.

This manual contains the bit definitions for compatible products available at the time of publication in Logic Command/Status Words: PowerFlex 525 Drives

page 157.

The Reference is a 16-bit word that is produced by the controller and consumed by the adapter. The Feedback is a 16-bit word produced by the adapter and consumed by the controller.

When using a ControlLogix or CompactLogix controller, the Reference is always INT 1 in the output image (see I/O Image for PowerFlex 525 Drives

on page 64)

and the 16-bit Feedback is always:

• INT 1 in the input image when using the drive Add-On Profile.

• INT 3 when using the Generic Profile.

The Reference and Feedback are 16-bit INT values represent drive speed. The scaling for the speed Reference and Feedback is 0.01 Hz. For example, a 16-bit INT Reference value of ‘3000’ would equal a Reference of 30.00 Hz. Note that the commanded maximum speed can never exceed the value of Host parameter P044 [Maximum Freq]. PowerFlex 525 Drive Example Speed Reference/

Feedback Scaling on page 65 shows example References and their results for a

PowerFlex 525 drive that has its:

• Host parameter P043 [Minimum Freq] set to 10.00 Hz.

• Host parameter P044 [Maximum Freq] set to 50.00 Hz.

Chapter 5 Using the I/O

IMPORTANT

There are several parameters in the drive that will override the start source and speed reference command if enabled. For details on these parameters, see the PowerFlex 525 drive’s user manual, publication 520-UM001

Attempting to write a negative value to the Speed Reference will result in the drive ramping to maximum speed due to overflow, the direction of the drive can only be controlled programmatically with the appropriate bits (bits 4 and

5) in the Command Word.

Using Datalinks

A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks allow a drive parameter value to be read or written to without using an Explicit Message. When enabled, each Datalink occupies one 16-bit word in a ControlLogix, CompactLogix, or MicroLogix controller.

The following rules apply when using PowerFlex 520-series drive Datalinks:

• Datalinks cannot be used with Multi-drive mode.

• The target of a Datalink can be any appropriate Host parameter. For

example, Host parameter P041 [Accel Time 1] can be the target of the Dual-port EtherNet/IP adapter installed in the drive.

• The data passed through the drive’s Datalink mechanism is determined by the settings of the following parameters:

– Device Parameter 02 [DLs From Net Act] – Device Parameter 03 [DLs To Net Act] – Host parameters C161 [Opt Data In 1] through

C164 [Opt Data In 4]

– Host parameters C165 [Opt Data Out 1] through

C168 [Opt Data Out 4]

A reset is always required after configuring Datalinks so that the changes take effect.

• When an I/O connection that includes Datalinks is active, those Datalinks being used are locked and cannot be changed until that I/O connection becomes idle or inactive.

• When you use a Datalink to change a value, the value is NOT written to the Non-Volatile Storage (NVS). The value is stored in volatile memory and lost when the drive loses power. Thus, use Datalinks when you need to change a value of a parameter frequently.

Datalinks for PowerFlex 520-series drive peripherals (embedded EtherNet/IP adapter on PowerFlex 525 drives only and option modules such as an encoder or communication adapter) are locked when the peripheral has an I/O connection with a controller. When a controller has an I/O connection to the drive, the drive does not allow a reset to defaults, configuration download or anything else that could change the makeup of the I/O connection in a running system. The I/O connection with the controller must first be disabled to allow changes to the respective Datalinks.

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

Using the I/O Chapter 5

Depending on the controller being used, the I/O connection can be disabled by:

• Inhibiting the module in RSLogix 5000 or Logix Designer software

• Putting the controller in Program mode

• Placing the scanner in idle mode

• Disconnecting the drive from the network

Example Ladder Logic Program Information

The example ladder logic programs in the sections of this chapter are intended for PowerFlex 520-series drives.

Functions of the Example Programs

The example programs enable you to:

• Receive Logic Status information from the drive.

• Send a Logic Command to control the drive (for example, start, stop).

• Send a Reference to the drive and receive Feedback from the drive.

• Send/receive Datalink data to/from the drive.

Logic Command/Status Words

These examples use the Logic Command word and Logic Status word for PowerFlex 525 drives. See Logic Command/Status Words: PowerFlex 525 Drives

on page 157 to view details.

CompactLogix Example

Creating Ladder Logic Using the Drive Add-On Profiles in RSLogix 5000 or Logix Designer Software

Since the drive Add-On Profile automatically created descriptive controller tags (see Controller Input Tags I/O image in Configuring the I/O control and monitor the drive without creating any ladder logic program. However, if you intend to use Human Machine Interface devices (PanelView, etc.) to operate the drive and view its status, you will need to create descriptive user-defined Program tags (see CompactLogix Program Tags for Drive Add-On

Profile Ladder Logic Program Example on page 68) and a ladder logic program

that will pass the Controller tag data to the Program tags.

ATT EN TI ON : Risk of equipment damage exists. If Explicit Messages are programmed to write parameter data to Non-Volatile Storage (NVS) frequently, the NVS will quickly exceed its life cycle and cause the drive to malfunction. Do not create a program that frequently uses Explicit Messages to write parameter data to NVS. Datalinks do not write to NVS and should be used for frequently changed parameters.

ATT EN TI ON : If you need to make frequent parameter changes using Explicit Messages, set Host parameter C121 [Comm Write Mode] to 1 “RAM only”.

About Explicit Messaging

See Using the I/O Command/Status, Reference/Feedback, and Datalinks.

Explicit Messaging is used to transfer data that does not require continuous updates. With Explicit Messaging, you can configure and monitor a device’s parameters on the network.

Rockwell Automation Publication 520COM-UM003A-EN-E - June 2013 73

on page 63 for information about the I/O Image, using Logic

When an explicit message is performed, by default no connection is made since it is an “unconnected” message. When timing of the message transaction is important, you can create a dedicated message connection between the controller and drive by checking the “Connected” box on the Communications tab message configuration screen during message setup. These message connections are in addition to the I/O connection. However, the trade off for more message connections is decreased network performance. If your application cannot tolerate this, do not check the “Connected” box, which is recommended.

Performing Explicit Messaging

There are five basic events in the Explicit Messaging process. The details of each step will vary depending on the type of controller being used. See the documentation for your controller.

There must be a request message and a response message for all Explicit Messages, whether you are reading or writing data.

Event Description

➊ You format the required data and set up the ladder logic program to send an Explicit Message request to the

scanner or bridge module (download).

➋ The scanner or bridge module transmits the Explicit Message Request to the slave device over the network. ➌ The slave device transmits the Explicit Message Response back to the scanner. The data is stored in the

scanner buffer.

➍ The controller retrieves the Explicit Message Response from the scanner’s buffer (upload). ➎ The Explicit Message is complete.

Single-Drive Mode Example for Network

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.

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

Multi-Drive Mode Example for Network

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.

• 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.

The AK-U0-RJ45-TB2P comes with (5) terminal block connectors and (2) terminating resistors.

Understanding the I/O Image

The terms input and output are defined from the scanner’s point of view. Therefore, Output I/O is data that is output from the scanner and consumed by the EtherNet/IP adapter. Input I/O is status data that is produced by the adapter and consumed as input by the scanner.

The I/O image table will vary based on the configuration of Host parameters C169 [MultiDrv Sel] and C175 [DSI I/O Cfg]. The image table always uses consecutive words starting at word 0.

IMPORTANT

Configuring the RS-485 Network

The following parameters must be set in the daisy-chained PowerFlex 4M drives and not in the master drive:

Parame ter Value

P106 [Start Source] 5 “Comm Port” P108 [Speed Reference] 5 “Comm Port” C302 [Comm Data Rate] 4 “19.2K” C303 [Comm Node Addr] 1...247 (must be unique) C306 [Comm Format] 0 “RTU-8-N-1”

Note: The RS-485 Multi-drive network is fixed at 19.2K baud rate, 8 data bits, no parity, and 1 stop bit.

Parameters [Comm Loss Action] and [Comm Loss Time] in the daisy-chained drives are still used in Multi-drive mode. If the RS-485 cable is disconnected or broken, the disconnected drive(s) will take the corresponding Comm Loss Action(s). On the EtherNet/ IP side, Device parameters 23 [Comm Flt Action] and 24 [Idle Flt Action] determine the action taken for ALL of the drives on the Multi-drive node.

The following Multi-drive parameters must be set in the master PowerFlex 525 drive:

Parame ter Value

P046 [Start Source 1] 4 “Network Opt” P047 [Speed Reference1] 4 “Network Opt” C169 [MultiDrv Sel] 1 “Network Opt”

Note: Drive must be power cycled after setting this parameter.

C171 [Drv 1 Addr] C172 [Drv 2 Addr] C173 [Drv 3 Addr] C174 [Drv 4 Addr]

C175 [DSI I/O Cfg] 0 “Drive 0”

2 3 4 5 Note: Drive must be power cycled after setting this

parameter.

1 “Drive 0-1” 2 “Drive 0-2” 3 “Drive 0-3” 4 “Drive 0-4” Note: Drive must be power cycled after setting this

parameter.

Parameters can be set using a DSI peripheral (22-HIM-A3 or 22-HIM-C2S) only when Host parameter C169 [MultiDrv Sel] is set to 0 “Disabled”.

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 Upl oad . 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 Upl oad is clicked, the drive settings are uploaded to the controller.

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