Safety Precautions

Please read the following safety precautions carefully.

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 embedded adapter. Failure to comply may result in injury and/or equipment damage.

ATT EN TI ON : Risk of equipment damage exists. The embedded 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. Drive parameters C143 [EN Comm Flt Actn] and C144 [EN Idle Flt Actn] let you determine the

action of the embedded EtherNet/IP 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.

Setting Up the Adapter

Since the EtherNet/IP adapter is embedded on the Main Control Board in the PowerFlex 525 drive, the only required step is setting its IP address and connecting it to the network.

Preparing for Set-Up

Before setting up the embedded EtherNet/IP adapter:

• 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 (version 18.0 or greater) 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

(Rockwell Automation publication

• Understand IGMP Snooping/Ethernet Switches

The embedded EtherNet/IP adapter is a multicast device. In most situations, an IGMP snooping (managed) switch is required. If more than one or two embedded EtherNet/IP 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 embedded EtherNet/IP adapter, RSLogix 5000 (version 18.0 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 embedded EtherNet/IP adapters are set up as unicast devices, then an IGMP snooping (managed) switch is not needed.

ENET-RM002

)

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-UM001A-EN-E - February 2013 15

Chapter 2 Setting Up 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.

Connecting the Adapter to the Network

There are two methods for configuring the embedded EtherNet/IP adapter’s IP address:

• BOOTP Server – Use BOOTP if you prefer to control the IP addresses of devices using a BOOTP server. The IP address, subnet mask, and gateway addresses will then be provided by the BOOTP server. This is enabled by default.

• Parameters – Use 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 parameters you set.

Regardless of the method used to set the adapter’s IP address, each node on the 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 drive.

ATT EN TI ON : Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death. Remove power from the drive, and then verify power has been discharged before connecting the embedded EtherNet/IP adapter to the network.

1. Remove power from the drive.

2. Remove the drive control module cover.

Applying Power

Install the control module cover, and apply power to the drive. The embedded EtherNet/IP adapter receives its power from the drive. When you apply power to the embedded EtherNet/IP adapter for the first time, the “ENET” status indicator on the drive LCD display should remain steady after an initialization. If it does not light up or is flashing, there is a problem. See

Troubleshooting.

Startup Status Indication

After power has been applied, status indicators for the PowerFlex 525 drive and embedded EtherNet/IP adapter can be viewed on the drive LCD display. See

Drive and Adapter Status Indicators

status indications.

ATT EN TI ON : 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.

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.

18 Rockwell Automation Publication 520COM-UM001A-EN-E - February 2013

Configuring the drive parameters can be done using the drive’s keypad, a HIM, RSLogix 5000/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 drive parameter P046 [Start Source 1] to 5 “EtherNet/IP”.

2. Set the value of drive parameter P047 [Speed Reference1] to 15 “EtherNet/IP”.

The PowerFlex 525 drive supports up to three control functions and three Reference functions.

device (usually a switch) on the other end of the cable is also set to automatically detect the data rate/duplex. If one device has the data rate/duplex hard-coded, the other device must be hard-coded to the same settings.

2. Reset the adapter by power cycling the drive.

Configuring the Adapter Chapter 3

Using Master-Slave Hierarchy

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.

For a Master-Slave hierarchy, the devices exchanging data must be on the same IP subnet. See “IP Addresses” in the

Glossary for information about IP subnets.

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 parameters C153 [EN Data In 1] through C156 [EN Data In 4], and C157 [EN Data Out 1] through C160 [EN 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 information on setting the connection size.

The [EN Data In x] and [EN Data Out x] parameters are named with respect to the master (controller), not the drive. [EN Data In x] parameters are for data incoming to the master (controller) from the drive, and [EN Data Out x] parameters are for data outgoing from the master (controller) to the drive.

Chapter 4 for more

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.

When using a ControlLogix or CompactLogix controller and an RSLogix 5000 (version 17.0 or greater) or Logix Designer (version 21.0 or greater) drive AddOn Profile, there is no need to configure Datalink parameters at this time. They will be assigned when configuring the drive Add-On Profile (see

Drive to the I/O Configuration on page 38).

Rockwell Automation Publication 520COM-UM001A-EN-E - February 2013 29

Adding the

Chapter 3 Configuring the Adapter

IMPORTANT

Enabling Datalinks To Write Data

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Parameters C157, C158, and C159 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.

Parameters C157 [EN Data Out 1] through C160 [EN Data Out 4] control which parameters in the drive, adapter, or any other connected peripheral receive values from the network. To configure these parameters, set them to the drive parameter number you want to write them to.

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

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

2. Reset the adapter by power cycling the drive.

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

Chapter 4

, Configuring the I/O.

Enabling Datalinks To Read Data

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Parameters C153, C154, and C155 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.

Parameters C153 [EN Data In 1] through C156 [EN Data In 4] configure which parameters in the drive, adapter, or any other connected peripheral send values to the network. To configure these parameters, set them to the parameter number you wish to read over the network.

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

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

2. Reset the adapter by power cycling the drive.

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

Chapter 4, Configuring the I/O.

Configuring the Adapter Chapter 3

Setting a Fault Action

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:

• Disrupted I/O communication by using parameter C143 [EN Comm Flt Actn].

• An idle controller by using parameter C144 [EN Idle Flt Actn].

ATT EN TI ON : Risk of injur y or equipment damage exists. Drive parameters C143 [EN Comm Flt Actn] and C144 [EN Idle Flt Actn] respectively let you determine the action of the embedded EtherNet/IP 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 parameters C143 [EN Comm Flt Actn] and C144 [EN Idle Flt Actn] to the desired responses:

Value Action Description

0 Fault The drive is faulted and stopped (Default). 1 Stop The drive is stopped as per P045 [Stop Mode] setting. 2 Zero Data The Reference and Datalink values transmitted to the drive will be set to “0”. 3 Hold Last The Reference and Datalink values transmitted to the drive will be held at their last value. 4 Send Flt Cfg The Logic, Reference, and Datalink values will be transmitted to the drive as configured in

C145 [EN Flt Cfg Logic], C146 [EN Flt Cfg Ref], and C157 [EN Data Out 1] through C160 [EN Data Out 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.

Setting the Fault Configuration Parameters

When setting parameter C143 [EN Comm Flt Actn] and C144 [EN Idle Flt Actn] 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. Changes to these parameters take effect immediately. A reset is not required.

Parameter Description

C145 [EN Flt Cfg Logic] A 16-bit value sent to the drive for Logic Command. C146 [EN Flt Cfg Ref] A 16-bit REAL (floating point) value sent to the drive for Reference. C157 [EN Data Out 1] through

Using RSLinx Classic

RSLinx Classic, in all its variations (Lite, Gateway, OEM, etc.), is used to provide a communication link between the computer, network, and controller. RSLinx Classic requires its network-specific driver to be configured before communications are established with network devices. To configure the RSLinx driver:

1. Start RSLinx and select Communications > Configure Drivers to display the Configure Drivers window.

2. From the Available Driver Types pull-down box, choose “EtherNet/IP Driver” and then click Add New… to display the Add New RSLinx Driver window.

3. Use the default name or type a name and click OK. The “Configure driver:” window appears.

4. Depending on your application, select either the browse local or remote subnet option, and click OK. The Configure Drivers window reappears with the new driver in the Configured Drivers list.

5. Click Close to close the Configure Drivers window. Keep RSLinx running.

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.

Configuring the I/O Chapter 4

1. Start RSLogix 5000/Logix Designer. The application window appears. Select File > Ne w 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-UM001A-EN-E - February 2013 37

Chapter 4 Configuring the I/O

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

• Drive Add-On Profiles (RSLogix 5000 version 17.0 or greater, Logix Designer version 21.0 or greater)

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

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

Using Drive Add-On Profiles with RSLogix 5000 (version 17.0 or greater) or Logix Designer (version 21.0 or greater)

When compared to using 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/ Logix Designer project file (.ACD) and also downloaded to the controller.

• Unicast connection (RSLogix 5000 version 18.0 or greater, or Logix Designer version 21.0 or greater)

• Drive Add-On Profiles enable I/O to be added online while the controller is in the Run mode.

• 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/

Adding the Drive 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 version 20.0 is used with drive Add-On Profile version 1.01 or later.

IMPORTANT

C160 [EN 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 C157, C158, and C159 to configure three Datalinks to write data and/or parameters C153, C154, C155, and C156 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 5.0

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/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.

Using Automatic Device Configuration (ADC) with RSLogix 5000 (version 20.0) or Logix Designer (version 21.0 or greater)

Automatic Device Configuration (ADC) is an RSLogix 5000 (version 20.0) and Logix Designer (version 21.0 or greater) feature that supports the automatic download of configuration data upon the Logix controller establishing an EtherNet/IP network connection to a PowerFlex 525 drive and its associated peripherals.

Configuring the I/O Chapter 4

IMPORTANT

TIP

IMPORTANT

• 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 embedded

EtherNet/IP adapter or future EtherNet/IP DLR adapter to a compatible controller.

An RSLogix 5000 (version 20.0) or Logix Designer (version 21.0 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 20.0) or Logix Designer (version 21.0 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.

Use with Stratix switches (Stratix 5700) to provide dynamic IP address assignment by port. This eliminates the need for the user to manually enter the IP address, Subnet mask, and Gateway address prior to connecting a replacement drive to the Ethernet network.

ADC can also work in tandem with Firmware Super visor. 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 for that port.

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.

Electronic Keying for HIMs and serial converters are disabled by default. These are typically temporary devices or used for monitoring purposes only and therefore “do not matter” if they are present or not. You still have the option to select these to other Keying selections if desired.

Electronic Keying settings for peripherals can be modified in the Drive tab of the AOP. Select the peripheral tab for the device you wish to modify, then click Properties.

Click OK when finished.

3. Select the Drive tab and click the ADC icon to open the ADC

Settings.

The ADC Settings window provides a single location for ADC configuration of the drive’s ports. Global checkboxes at the top of each column checks or unchecks the entire column. Ports can also be turned on/off individually. See the checkbox selection information in Step 3 for additional details.

Click OK when finished.

4. Perform the above steps for each additional PowerFlex 525 drive.

5. Save your project and download the project to the Logix controller.

Rockwell Automation Publication 520COM-UM001A-EN-E - February 2013 49

Chapter 4 Configuring the I/O

ADC and Logix Memory

Starting in RSLogix 5000 version 16.0, 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

Proper ties).

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/Logix Designer.

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

4. Use RSLogix 5000/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 Prop erties. On the Controller Properties window, select the Nonvolatile Memory tab.

50 Rockwell Automation Publication 520COM-UM001A-EN-E - February 2013

Configuring the I/O Chapter 4

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-UM001A-EN-E - February 2013 51

Using the RSLogix 5000 (version 17.0 or greater) or Logix Designer (version 21.0 or greater) Generic Profile

The basic RSLogix 5000/Logix Designer Generic Profile is only recommended when:

• A specific drive profile in other versions of RSLogix 5000/Logix Designer 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 17.0 or greater and Logix Designer version 21.0 or greater).

• A project must maintain specific revision level control.

• The controller cannot be taken offline. RSLogix 5000 (version 17.0 or

greater) and Logix Designer (version 21.0 or greater) enables the drive Generic Profile to be added while the controller is online and in the Run mode.

Adding the Drive to the I/O Configuration

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 29), 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 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/Logix Designer, 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/Logix Designer window, select Communications > Download. The Download dialog box appears.

Using RSLinx Classic

on page 35 for details.

2. Click Download to download the configuration to the controller. When the download is successfully completed, RSLogix 5000/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 29). 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/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

Understanding the I/O Image

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 525 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/Logix Designer. 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.

Chapter 3

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.

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:

• 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 17.0 or greater) and Logix Designer (version 21.0 or greater) 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/Logix Designer, however, controller tags are not descriptive.

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, CompactLogix, or MicroLogix 1100/1400 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.

IMPORTANT

Using Reference/Feedback

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, CompactLogix, or MicroLogix 1100/1400 controller, the Reference is always INT 1 in the output image (see

PowerFlex 525 Drives on page 60) 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 values which represent drive speed in

0.01 Hz.

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

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 525 drive Datalinks:

• Datalinks cannot be used with Multi-drive mode.

• The target of a Datalink can be any parameter, including those of a

peripheral. For example, drive parameter P041 [Accel Time 1] can be the target of the embedded EtherNet/IP adapter and any or all Option Cards installed in the drive.

• The data passed through the drive’s Datalink mechanism is determined by the settings of parameters C157...C160 [EN Data Out 1...4] and parameters C153...C156 [EN Data In 1...4].

• 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 525 drive peripherals (embedded EtherNet/IP adapter and Option Modules such as a communication module) 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

Rockwell Automation Publication 520COM-UM001A-EN-E - February 2013 61

Chapter 5 Using the I/O

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.

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

• Inhibiting the module in RSLogix 5000/Logix Designer

• Putting the controller in Program mode

• Placing the scanner in idle mode

• Disconnecting the drive from the network

Example Ladder Logic Program Information

CompactLogix Example

The example ladder logic programs in the sections of this chapter are intended for PowerFlex 525 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

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.

, Using the I/O 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.

Explicit Messaging Process

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.

For information on the maximum number of Explicit Messages that can be executed at a time, see the documentation for the bridge or scanner and/or controller that is being used.

(4) In this example, we are reading five 16-bit parameters. Each parameter being read requires two contiguous INT registers. Therefore,

a controller tag was created with its Data Type field set to “INT[10].” Also, the Source Length field on the Message Configuration

screen must correspond to the selected Data Type in bytes (for this example, 20 bytes for an INT[10] array). Scattered read messages

always assume that every parameter be ing read is a16-bit parameter, regardless of its actual size. Maximum message length is 25 6

bytes which can read up to 6 4 parameters, regardless of their size. (5) The controller tag for “Scattered_Read_Response” must be the same size as the controller tag for “Scattered_Read_Request” (for

this example, 20 bytes), but can be a different data type (for this example, a UDDT to handle conver sions to parameter values that

are a REAL data type).

Single-Drive Mode vs. MultiDrive Mode

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.

Single-drive mode is a typical network installation, where a single EtherNet/IP node consists of a single drive with an EtherNet/IP adapter.

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 82). The first drive must be a PowerFlex 525 drive.

The remaining drives can be any PowerFlex drive which supports Multi-drive mode.

AK-U0-RJ45-TB2P

For the examples in the chapter, we will use the PowerFlex 525 as a master drive with four daisy-chained PowerFlex 4M drives.

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 525 with embedded 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 embedded 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:

Drive Additional Throughput Time

PowerFlex 525 0 ms PowerFlex 525 plus 1 drive +24 ms PowerFlex 525 plus 2 drives +48 ms PowerFlex 525 plus 3 drives +72 ms PowerFlex 525 plus 4 drives +96 ms

• 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 of 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.

Understanding the I/O Image

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

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 parameters C169 [MultiDrv Sel] and C175 [DSI I/O Cfg]. The image table always uses consecutive words starting at word 0.

Multi-Drive Example of I/O Image on page 84 is an illustration of the

Using the RSLogix 5000 (version 17.0 or greater) or Logix Designer (version 21.0 or greater) Generic Profile on page 53 for instructions.

Multi-Drive Example of I/O Image

See

on page 84 for the number of 16-bit

input and output words to use for your application. In this example, the number of input words is 12 and the number of output words is 10.

Function of the Example Program

The example program provided is for the CompactLogix family, but other Logixbased controllers can also be used similarly. This example program enables you to:

• View status information from the drives such as Ready, Fault, At Speed, and Feedback.

• Control the drives using various Logic Command bits (Stop, Start, etc.) and Reference.

• Perform a single parameter read and write for each drive. The example uses PowerFlex 4M drive parameter P109 [Accel Time 1] for both so you can see (read) the change after a write is performed.

The same programming approach can be used with the tags generated by the Multi-drive Add-On Profile. Note that the tags used in this example will be different from those created by the Multi-drive Add-On Profile.

Drive 0 (PowerFlex 525) Settings for the Example Program

• Parameter C169 [MultiDrv Sel] is set to 2 “EtherNet/IP”.

• The following parameters are set:

Parameter Value Description

P046 [Start Source1] 5 “EtherNet/IP” P047 [Speed Reference1] 15 “EtherNet/IP ” C175 [DSI I/O Cfg] 4 “Drive 0-4” (5 drives on 1 node) C171 [Drv 1 Addr] C172 [Drv 2 Addr] 2 Modbus address of Drive 2 C173 [Drv 3 Addr] 3 Modbus address of Drive 3 C174 [Drv 4 Addr] 4 Modbus address of Drive 4

Main Routine

The Main Routine reads the network Input Image from the scanner, calls the various drive control subroutines, and writes the network Output Image to the scanner. See

Main Routine

Main Routine on page 98.

CompactLogix EtherNet/IP Multi-Drive example program with a PowerFlex 525 on EtherNet/IP. Four PowerFlex 4M drives are daisy-chained to the main PowerFlex 525 using their RJ45 ports (RS-485). I n this mode, up to ﬁve PowerFlex drives can exist on one EtherNet/IP node.

This rung retrieves the Logic Status and Feedback data for all ﬁve drives from the scanner (DINTs), and moves it to speciﬁc INT tags for use elsewhere in the ladder program. The input image is as follows:

Drive_Input_Image[2] and Drive_Input_Image[3] = Drive 0 Logic Status and Feedback Drive_Input_Image[4] and Drive_Input_Image[5] = Drive 1 Logic Status and Feedback Drive_Input_Image[6] and Drive_Input_Image[7] = Drive 2 Logic Status and Feedback Drive_Input_Image[8] and Drive_Input_Image[9] = Drive 3 Logic Status and Feedback Drive_Input_Image[10] and Drive_Input_Image[11] = Drive 4 Logic Status and Feedback
