Chapter 1 Getting Started

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 PROFIBUS 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 11 [Comm Flt Action] and 12 [Idle Flt Action] let you determine the action

of the adapter and drive if I/O communication is 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 (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 an Installation

Commissioning the Adapter

Before installing the adapter, do the following:

• Read the PROFIBUS Installation Guideline for details on PROFIBUS networks.

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

on page 9.

To commission the adapter, you must set the Endianness and a unique node address that is used by the network. See the Glossary

on page 85 for details about

node addresses.

There are two methods for configuring the adapter’s Endianness and node address:

• Using the onboard DIP Switches;

• Using adapter parameters – Use adapter parameters when you want more

flexibility in setting up the node address. To set the node address using adapter parameters, see Setting the Node Address

on page 25.

Regardless of the method used to set the adapter’s node address, each node on the network must have a unique node address.

Chapter 2 Installing the Adapter

IMPORTANT

Node Address switches (1...7)

Byte Swap switch (8)

Setting the Endianness and Node Address Using the DIP Switches

Set the Endianness of the adapter with Byte Swap switch 8. The Byte Swap switch can be set to either OFF ‘0’ (Little Endian) or ON ‘1’ (Big Endian) data formats for the data exchanged on the network. The data consists of the following items:

• CTRL: Logic Command Word (four bytes)

• REF: Speed Reference (two bytes)

• STAT: Logic Status Word (four bytes)

• FEEDBACK: Speed Feedback (two bytes)

• zero to eight Datalinks (two bytes each)

• Acyclic messaging

Depending on the setting of the Byte Swap switch 8, the two bytes for each of the above data items are swapped.

Each node on the PROFIBUS network must have a unique address. Set the node address before power is applied because the adapter detects the node address during initialization (Power On Reset). Unless using the Set Slave Address service in which the address change occurs without requiring a power cycle.

Set the Node Address by setting the Node Address switches 1 through 7 to their binary equivalent, where ‘0’ and ‘1’ indicate switch positions ‘OFF’ and ‘ON’ respectively. Node Address Switch Settings

on page 15 lists node addresses and

the corresponding Node Address switch settings required to set that respective address.

Configuring/Verifying Key Drive Parameters

The PowerFlex 520-series 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, 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”.

2. Set the value of Host parameter P047 [Speed Reference1]

Chapter 3 Configuring the Adapter

IMPORTANT

Using Master-Slave Hierarchy (Optional)

This procedure is only required if Datalinks are used to write or read data of the drive. A hierarchy determines the type of device with which the adapter exchanges data. In a Master-Slave hierarchy, the adapter exchanges data with a PROFIBUS master, such as a Prosoft MVI69-PDPMV1 Master Network Interface module for CompactLogix.

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 PROFIBUS Master

the connection 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 31 for more information on setting

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:

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 by power cycling the drive.

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 PROFIBUS

Master on page 31.

26 Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013

Configuring the Adapter Chapter 3

IMPORTANT

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.

2. Reset the adapter by power cycling the drive.

Setting a Fault Action

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 PROFIBUS Master

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 11 [Comm Flt Action].

• An idle controller by using Device parameter 12 [Idle Flt Action].

ATT EN TI ON : Risk of injury or equipment damage exists. Device parameters 11 [Comm Flt Action] and 12 [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 a controller in idle state).

on page 31.

Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013 27

Chapter 3 Configuring the Adapter

Changing the Fault Action

Set the values of Device parameters 11 [Comm Flt Action] and 12 [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

the drive remains unchanged.

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

parameters (Device parameters 13 [Flt Cfg Logic], 14 [Flt Cfg Ref], and 15 [Flt Cfg DL 1] through 18 [Flt Cfg DL 4]).

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

If communication is disrupted and then re-established again, the drive will automatically receive commands over the network again.

Setting the Fault Configuration Parameters

Resetting the Adapter

When setting Device parameters 11 [Comm Flt Action] and 12 [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 occurs. You must set these parameters to values required by your application.

Device Parameter Description

13 [Flt Cfg Logic] A 16-bit integer value sent to the drive for Logic Command.

14 [Flt Cfg Ref] A 16-bit integer value sent to the drive for Reference.

15 [Flt Cfg DL 1] through 18 [Flt Cfg DL 4]

A 16-bit integer value sent to the drive for a Datalink.

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

Changes to switch settings on 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 19 [Reset Module].

Set Device parameter 19 [Reset Module] to 1 “Reset Module”.

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.

Restoring Adapter Parameters to Factory Defaults

Viewing the Adapter Status Using Parameters

Set Device parameter 19 [Reset Module] to 2 “Set Defaults”.

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”.

The following Device parameters provide information about the status of the adapter. You can view these parameters at any time using the PowerFlex 22-HIM-A3 or 22-HIM-C2S HIM or Connected Components Workbench.

connection opened by the controller.

03 [DLs To Net Act] Displays the number of drive-to-network Datalinks that the controller is using based on the

I/O connection opened by the controller.

04 [Net Addr Src] Displays the source from which the adapter’s node address is taken. This will be either the

Node Address switches (see Setting the Endianness and Node Address Using the DIP Switches

on page 14) or the value of Device parameter 05 [Net Addr Cfg].

06 [Net Addr Act] Displays the actual network node address used by the adapter, which can be one of the

following:

• The address set with the Node Address switches (see Setting the Endianness and Node

Address Using the DIP Switches on page 14).

• The Set Slave Address service, sets the value of the new address into the Device parameter 05 [Net Addr Cfg]. It is saved in Non-volatile memory, but takes effect immediately.

• An old address from the switches or parameter. (If either has been changed, but the

adapter has not been reset, the new address will not be in effect.)

The adapter firmware can be updated over the network or through DSI using a tool such as the 1203-USB serial converter.

When updating firmware over the network or DSI, you can use the Allen-Bradley ControlFLASH software tool.

ProSoft Configuration Builder (PCB) software uses PROFIBUS slave definition files (GSD files) to obtain basic configuration information about the PROFIBUS slaves you add to the network. The GSD configuration files identify the slave’s capabilities so that the MVI69-PDPMV1 module can communicate with it correctly.

Example: The 25-COMM-P GSD file is named ‘ROCK0E0B.gsd’. It is the GSD file for the 25-COMM-P adapter in the drive and can be downloaded at

Configuring the Adapter as a Slave

Follow these steps to add and configure a 25-COMM-P adapter as a slave.

1. Drag the Slave icon into the Bus Configuration window. The slave is added to the PROFIBUS network and configured to the Master in a networked relationship.

2. In the treeview, click ‘+’ to expand the slave you added.

The list in the window above shows the possible input/output configuration values for a 25-COMM-P Slave. The Datalinks (1...4) allow the assignment of configured drive parameters to be included in the PROFIBUS DP I/O data frames that are transferred between the CompactLogix controller and the PowerFlex 520-series drive.

3. Click on the 25-COMM-P in the Bus Configuration window.

Configuring the PROFIBUS Master Chapter 4

IMPORTANT

4. Drag the input and output parameters to the Slot Location Grid (Subscriber List) below the Bus Configuration window. This view displays the slot number, configuration data, and starting input and output addresses that will be assigned in the controller memory for the MVI69-PDPMV1 Master. The Master uses this information to identify and communicate with individual slaves on the network.

For this example, we will configure words for Ctrl/Stat & Ref/Fdbk as well as the four input and four output datalinks. These input and output 16-bit values are assigned to addresses within the MVI69-PDPMV1 Master’s internal database. For each new slave added to the PROFIBUS network, the PCB software automatically converts the input/output byte addresses to input and output image addresses for the tag database in the CompactLogix processor.

Datalink modules must be configured in order:

Slot 2 = Datalink 1 Slot 3 = Datalink 2 Slot 4 = Datalink 3 Slot 5 = Datalink 4

If this is not done the 25-COMM-P will reject the configuration during the startup of the Data Exchange.

When in Multi-drive mode this is also the case. The Drive 1...4 modules should be added in order 1, 2, 3, 4 in the ascending slot numbers, or the device will reject the configuration when trying to enter the Data Exchange mode of operation.

About I/O Messaging

PROFIBUS DPV0 or I/O messaging is used to transfer the data which controls the PowerFlex drive and its Reference. I/O messaging can also be used to transfer data to and from Datalinks which are mapped to parameters in the PowerFlex 520-series drives.

The adapter includes the Logic Command, Logic Status, Reference, and Feedback (all as 16-bit words). This requires four bytes for the Input Size and four bytes for the Output Size in the controller’s I/O image. This basic I/O must be always configured by the PROFIBUS configuration tool to the 25-COMM-P adapter, enabling the ability to control and monitor the PowerFlex 520-series drive. 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.

Configuring the Adapter page 31 discuss how to configure the adapter and controller on the network for

the required I/O. This chapter discusses how to use I/O after you have configured the adapter and controller.

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 status 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...C164 [Opt Data In

1...4] and C165...C168 [Opt Data Out 1...4]) are used.

If all available I/O is not used, the image is truncated. The image always uses consecutive words starting at word zero.

CompactLogix Controller I/O Image for PowerFlex 520-Series Drives

page 42 shows the I/O image when using all of the 16-bit Datalinks.

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 CompactLogix or ControlLogix 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.

This manual contains the bit definitions for compatible products available at the time of publication in Logic Command/Status Words: PowerFlex 520-Series

Drives on page 81.

The Reference is a 16-bit INT (integer) produced by the controller and consumed by the adapter. The Feedback is a 16-bit INT produced by the adapter and consumed by the controller.

When using a CompactLogix or ControlLogix controller, the 16-bit INT Reference word is always INT 1 in the output image (see CompactLogix

Controller I/O Image for PowerFlex 520-Series Drives on page 42) and the

16-bit INT Feedback is always INT 1 in the input image.

The Reference and Feedback 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

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 a PROFIBUS DPV1 Service. When enabled, each Datalink occupies one 16-bit word in a ControlLogix, CompactLogix, or MicroLogix controller, providing a mirror of the PowerFlex 520-series drive data value that the Datalinked parameter represents.

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

• 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 adapter installed in the drive.

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

– Host parameters C161...C164 [Opt Data In 1...4] – Host parameters C165...C168 [Opt Data Out 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 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 are locked when the adapter has an I/O connection with a controller. When a controller has an I/O connection to the adapter, the drive does not allow a reset to defaults, configuration download or anything else that could change the

Chapter 5 Using the I/O

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:

• Putting the controller in Program mode

• Placing the master in idle mode

• Disconnecting the drive from the network

I/O Communication

The following example describes how to use PROFIBUS DPV0 I/O communication for the CompactLogix controller for the PROFIBUS MVI69PDPMV1 Master.

I/O data transferred to and from the 25-COMM-P adapter nodes can be viewed in the MVI69-PDPMV1 CompactLogix controller tags for the DPV0 cyclic communication connections. See Input Mapping in the MVI69-PDPMV1

About Acyclic Messaging

Acyclic Messaging for DPV1 Class 49

Acyclic Messaging Examples 49

ATT EN TI ON : Risk of equipment damage exists. If Acyclic 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 Acyclic 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 Acyclic Messages, set Host parameter C121 [Comm Write Mode] to 1 “RAM only”.

About Acyclic Messaging

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

Acylic messaging is used to transfer data that does not require continuous updates. Acylic messaging, or DPV1 messaging in the case of the 25-COMM-P adapter, is also used to configure and monitor drive’s parameters on a PROFIBUS network. Host (drive) parameters as well as Device (adapter) parameters can be accessed using acyclic messaging for a PowerFlex 520-series drive. For a full list of Host (drive) parameters, see the PowerFlex 520-Series Adjustable Frequency AC Drive User Manual, publication 520-UM001 a list of Device (adapter) parameters, see Adapter Parameters acyclic messaging read and write services, you need the values of the slot and index to which a parameter is associated.

For accessing any parameter within a drive, a general mechanism is used to map the parameter with a PROFIBUS slot and index number.

Every drive device port has a base slot number which supports 256 indices in a slot. These slot and index combinations are mapped to various drive and adapter parameters through the 25-COMM-P adapter. These are the general formulas used to determine the slot and index numbers for a specific parameter.

Slot Number = Base Slot Number + Quotient of (parameter number / 256) Index Number = Remainder of (parameter number / 256)

Due to PROFIBUS standard requirements of various identification and maintenance functions, there is an exception to the rule for assigning Host (drive) parameters. When accessing Host parameters, the slot number will start at 0x01. This is the formula used to determine the slot number for a Host parameter.

Slot Number = Base Slot Number + Quotient of (parameter number / 256) + 1

The following examples illustrates the use of these formulas.

Example 1: To a cc es s Host parameter 41[Accel Time 1], see PROFIBUS Slot

and Index for Drive and Adapter Parameters on page 48 to find the slot number

associated with Drive 0, which can be used to access the first 256 parameters. To access parameters 257...512, the slot number will increment by 1, and so on.

For Drive 0, the base slot number is 0x00 + 1 (per the exception). Therefore, the slot number can be calculated using the general formula:

Slot Number = 0x00 + Quotient of (41 / 256) + 1 (for Drive Host Parameters) = 0x01

The index number will be the remainder of the Host parameter number divided by 256, as shown using this formula:

Index Number = Remainder of (41 / 256) = 41

Example 2: To a cc es s Device parameter 5 [Net Addr Cfg] in the adapter, see

PROFIBUS Slot and Index for Drive and Adapter Parameters

on page 48.

For Device parameters, the base slot number is 0x15. Therefore, the slot number can be calculated using the general formula:

Slot Number = 0x15 + Quotient of (5 / 256) = 0x15

The index number will be the remainder of the Device parameter number divided by 256, as shown using this formula:

Index Number = Remainder of (5 / 256) = 5

Acyclic Messaging for DPV1 Class

Acyclic Messaging Examples

The 25-COMM-P adapter provides the following PROFIBUS DPV1 Class 1 Acyclic Services:

• READ – This service is used to read a parameter in the PowerFlex 520series drive or the adapter.

• WRITE – This service is used to write a parameter in the PowerFlex 520series drive or the adapter.

Examples of using PROFIBUS DPV1 Class 1, Acyclic Messaging to read and write a Host (drive) parameter is described in this section.

Read Example for Host Parameter 1 [Output Freq]

To read the PowerFlex 520-series drive parameter 1 [Output Freq] using a Class 1 Acyclic Read Service, setup a CompactLogix controller (with a MVI69PDPMV1 PROFIBUS Master). After the master is setup, the CompactLogix tags must be populated with the values to read the parameter as shown in Class 1

Acyclic Read for Host Parameter 1 [Output Freq] on page 50.

Host parameter 1 [Output Freq]:

• Slot Number = 0x00 + Quotient of (1/256) + 1 = 1

• Index Number = Remainder of (1/256) = 1

• Length in bytes of the value of the parameter (16-bit integer value) / 8 = 2

To test the Read service, you may manually enter the values as shown below into the MVI69-PDPMV1 controller scoped tags, where a ProSoft MVI69PDPMV1 PROFIBUS master module is installed in the backplane of the CompactLogix controller rack.

• MVI69PDPMV1.Mailbox.Class1AcyclicRead.Out.SlotNumber = 1

• MVI69PDPMV1.Mailbox.Class1AcyclicRead.Out.SlaveAddress = 3

• MVI69PDPMV1.Mailbox.Class1AcyclicRead.Out.Length = 2

• MVI69PDPMV1.Mailbox.Class1AcyclicRead.Out.Index = 1

Next, manually enter a value of ‘1’ into the MVI69PDPMV1.MailboxCommand.Class1AcyclicRead tag to send the message.

Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013 49

Chapter 6 Using Acyclic Messaging

Class 1 Acyclic Read for Host Parameter 1 [Output Freq]

Change value of tag to “1” to send Class 1 Acyclic Read Command.

Copy or insert values for parameter read request:

- Parameter Slot Number

- Slave Node Address

- Length of Data (Bytes)

- Parameter Index

When the message response successfully returns, the data for the Output Frequency parameter will be placed in the tags MVI69PDPMV1.Mailbox.Class1AcyclicRead.In.Data[] byte array. In the controller program, the return message data may be copied to a locally configured program tag, and converted by correctly assigning the data type for the Local tag to which the data returned from the read requests matches. In this Host parameter 1 [Output Freq] example, the local tag’s data type should be an integer.

Class 1 Acyclic Read response data can be viewed as shown in Class 1 Acyclic

Write Example for Host Parameter 41 [Accel Time 1]

To write to the PowerFlex 520-series drive parameter 41[Accel Time 1] using a Class 1 Acyclic Write Service, setup a CompactLogix controller (with a MVI69PDPMV1 PROFIBUS Master). After the master is setup, the CompactLogix tags must be populated with the correct slot and index addressing values to write the parameter as shown in Class 1 Acyclic Write for

Time 1] on page 53.

Host parameter 41[Accel Time 1]:

• Slot Number = 0x00 + Quotient of (41/256) + 1 = 1

• Index Number = Remainder of (41/256) = 41

• Length in bytes of the value of the parameter (16-bit integer value) / 8 = 2

To test the Write Service, you may manually enter the values as shown below into the MVI69-PDPMV1 controller scoped tags where a ProSoft MVI69-PDPMV1 PROFIBUS master module has been installed in the backplane of the CompactLogix controller rack.

• MVI69PDPMV1.Mailbox.Class1AcyclicWrite.Out.SlotNumber = 1

• MVI69PDPMV1.Mailbox.Class1AcyclicWrite.Out.SlaveAddress = 3

• MVI69PDPMV1.Mailbox.Class1AcyclicWrite.Out.Length = 2

• MVI69PDPMV1.Mailbox.Class1AcyclicWrite.Out.Index = 41

The data bytes to be written can be entered in the MVI69PDPMV1.Mailbox.Class1AcyclicWrite.Out.Data[] array, or the data may be copied using ladder logic and a locally configured program tag which represents the correct data type, for the data value, to be written to Host parameter 41 [Accel Time 1]. In this example, the value would be an integer data type. The value shown in Class 1 Acyclic Write for

Host Parameter 41 [Accel

Time 1] on page 53 indicates a value of 20.00 seconds.

Single-drive mode is a typical network installation, where a single PROFIBUS node consists of a single drive with a PROFIBUS adapter.

Single-Drive Mode Example for Network

Multi-drive mode is an alternative to the typical network installation, where a single PROFIBUS node can consist of one to five drives (see Multi-Drive Mode

Example for Network on page 56). 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.

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.

56 Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013

The trade-offs of Multi-drive mode include:

• If the PowerFlex 520-series drive with 25-COMM-P 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 PROFIBUS (Single-drive mode). This is because the 25-COMM-P adapter must take the PROFIBUS 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

• Since the RS-485 ports are used for daisy-chaining the drives, there is no connection for a peripheral device such as a HIM or USB converter module (1203-USB). DSI Splitter cables cannot be used to add a second connection for a peripheral device.

System Wiring

To daisy-chain the drives to the PowerFlex 525, the AK-U0-RJ45-TB2P terminal block connector can be used for easy installation.

The wiring diagram for using AK-U0-RJ45-TB2P terminal block connectors is shown below.

Understanding the I/O Image

Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013 57

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

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

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

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 PROFIBUS side, Device parameters 11 [Comm Flt Action] and 12 [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.

Chapter 7 Using Multi-Drive Mode

Multi-Drive Ladder Logic Program for Generic Profile

The following is an example of the ladder logic program for the Generic Profile and demonstrates using Multi-drive mode with five drives. See Multi-Drive

Mode Example for Network on page 56 for an example of a system layout

diagram.

See Multi-Drive Example of I/O Image

on page 58 for the number of 16-bit

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

Function of the Example Program

The example program provided is for the CompactLogix family of controllers, but other Logix-based 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.

Drive 0 (PowerFlex 525) Settings for the Example Program

• Parameter C169 [MultiDrv Sel] is set to 1“Network Opt”.

• The following parameters are set:

Parameter Value Description

P046 [Start Source1] 4 “Network Opt”

P047 [Speed Reference1] 4 “Network Opt”

C175 [DSI I/O Cfg] 4 “Drive 0-4” (5 drives on 1 node)

Multi-Drive Mode Acyclic Messaging

(End)

Acyclic messaging in Multi-drive mode is similar to Single-drive mode but the slot numbers will change depending on which drive you are messaging to. See

PROFIBUS Slot and Index for Drive and Adapter Parameters

on page 48 to

determine the correct slot values to set up your message.

Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013 67

Chapter 7 Using Multi-Drive Mode

For example, to access [Accel Time 1] (parameter P041 in PowerFlex 525 and P109 in PowerFlex 4M) in each of the drives, the following slot and index values would be used:

• Drive 0 (PowerFlex 525) Slot = 1, Index = 41

• Drive 1 (PowerFlex 4M) Slot = 5, Index = 109

• Drive 2 (PowerFlex 4M) Slot = 9, Index = 109

• Drive 3 (PowerFlex 4M) Slot = 13, Index = 109

• Drive 4 (PowerFlex 4M) Slot = 17, Index = 109

Additional Information

• When the PowerFlex 525 drive (Drive 0) is powered up, all configured daisy-chained drives must be present before the 25-COMM-P adapter will enter the Data Exchange mode. The PORT LED status indicator will flash red while it is starting up.

• If the PowerFlex 525 drive (Drive 0) is powered down, communications with the four daisy-chained drives (Drive 1 to Drive 4) are disrupted and the drives will take their corresponding Comm Loss Actions.

• If any of the daisy-chained drives (Drive 1 to Drive 4) are powered down, the respective Input Image (Logic Status and Feedback) will be set to zero. Status information will not indicate there is a fault at the node, and the I/O connection will not be dropped.

Viewing and Clearing Events

Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013 71

The adapter’s diagnostic items cannot be viewed in Multi-drive mode.

The adapter has an event queue to record significant events that occur in the operation of the adapter. When such an event occurs, an entry consisting of the event’s numeric code and a timestamp is put into the event queue. You can view the event queue using the PowerFlex 22-HIM-A3/-C2S HIM or Connected Components Workbench software.

The event queue can contain up to 32 entries, which are stored in an EEPROM chip—making the event queue nonvolatile. Eventually the event queue will become full, since its contents are retained through adapter power cycles and resets. At that point, a new entry replaces the oldest entry. Only an event queue clear operation will clear the event queue contents.

Chapter 8 Troubleshooting

Resetting the adapter to defaults has no effect on the event queue, other than to log a Code 58 “Module Defaulted” event.

Many events in the event queue occur under normal operation. If you encounter unexpected communications problems, the events may help you or Allen-Bradley personnel troubleshoot the problem. The following events may appear in the event queue:

Glossary

The following terms and abbreviations are used throughout this manual. For definitions of terms not listed here, see the Allen-Bradley Industrial Automation Glossary, publication AG-7.1

Adapter Devices such as drives, controllers, and computers usually require an adapter to

provide a communication interface between them and a network such as PROFIBUS. An adapter reads data on the network and transmits it to the connected device. It also reads data in the device and transmits it to the network.

The 25-COMM-P PROFIBUS DPV1 adapter connects PowerFlex 520-series drives to a PROFIBUS DPV0/DPV1 network. Adapters are sometimes also called ‘cards’, ‘embedded communication options’, ‘modules’, and ‘peripherals’.

Acyclic Messaging PROFIBUS DPV1 acyclic messages are used to transfer data that does not

require continuous updates. Typically the read and write services used for acyclic messaging are used to configure, monitor, and diagnose devices over the PROFIBUS network.

system that has a user-programmable memory for storage of instructions to implement specific functions such as I/O control, logic, timing, counting, report generation, communication, arithmetic, and data file manipulation. A controller consists of a central processor, input/output interface, and memory. See also master.

Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013 85

Glossary

Data Rate The speed at which data is transferred on the PROFIBUS network. The available

data rates depend on the type of cable and total cable length used on the network.

Data Rate Maximum Cable Length Data Rate Maximum Cable Length

9.6 K 1000 m (3,280 ft) 500 K 400 m (1,312 ft)

19.2 K 1000 m (3,280 ft) 1.5 M 200 m (656 ft)

45.45 K 1000 m (3,280 ft) 3 M 100 m (328 ft)

93.75 K 1000 m (3,280 ft) 6 M 100 m (328 ft)

187.5 K 1000 m (3,280 ft) 12 M 100 m (328 ft)

Datalinks A Datalink is a type of pointer used by PowerFlex 520-series drives to transfer

data to and from the controller. Datalinks allow specified parameter value(s) to be accessed or changed. When enabled, each 16-bit Datalink in a PowerFlex 520series drive consumes 2 bytes in the input image table and/or 2 bytes in the output image table of the controller.

Fault Action A fault action determines how the adapter and connected drive act when a

communications fault (for example, a cable is disconnected) occurs or when the controller is switched out of run mode. The former uses a communications fault action, and the latter uses an idle fault action.

Fault Configuration When communications are disrupted (for example, a cable is disconnected), the

adapter and its PowerFlex 520-series drive can respond with a user-defined fault configuration. The user sets the data that is sent to the drive using specific fault configuration parameters in the adapter. When a fault action parameter is set to use the fault configuration data and a fault occurs, the data from these parameters is sent as the Logic Command, Reference, and/or Datalink(s).

GSD (Generic Station Description)

A device database text file used by the network configuration tool to identify a

File

PROFIBUS module and its capabilities. The file is normally registered in the PROFIBUS configuration tool for a device, and is supplied with the device via removable media or on the internet as a download.

HIM (Human Interface Module) A device that can be used to configure and control a drive. The PowerFlex 22-

HIM-A3 or 22-HIM-C2S HIM can be used to configure PowerFlex 520-series drives and their connected peripherals.

Hold Last When communication is disrupted (for example, a cable is disconnected), the

adapter and its PowerFlex 520-series drive can respond by holding last. Hold last results in the drive receiving the last data received through the network connection before the disruption. If the drive was running and using the Reference from the adapter, it will continue to run at the same Reference.

Idle Action An idle action determines how the adapter and its PowerFlex 520-series drive act

when the controller is switched out of run mode.

86 Rockwell Automation Publication 520COM-UM004A-EN-E - November 2013

I/O Data I/O data, sometimes called “implicit messages” or “input/output,” is time-critical

data such as a Logic Command and Reference. The terms “input” (To Net) and “output” (From Net) are defined from the controller’s point of view. Output is produced by the controller and consumed by the adapter. Input is produced by the adapter and consumed by the controller.

Logic Command/Logic Status The Logic Command is used to control the PowerFlex 520-series drive (for

example, start, stop, direction). It consists of one 16-bit word of output to the adapter from the network. The definitions of the bits in this word are shown in

Logic Command/Status Words: PowerFlex 520-Series Drives

on page 81.

The Logic Status is used to monitor the PowerFlex 520-series drive (for example, operating state, motor direction). It consists of one 16-bit word of input from the adapter to the network. The definitions of the bits in this word are shown in

Logic Command/Status Words: PowerFlex 520-Series Drives

on page 81.

Master-Slave Hierarchy An adapter configured for a master-slave hierarchy exchanges data with the

master device. Usually, a network has one master which is the master device, and all other devices (for example, drives connected to PROFIBUS DPV1 adapters) are slave devices.

Glossary

On a network with multiple masters (called a multi-master hierarchy), each slave device must have one specified master.

MVI69-PDPMV1 PROFIBUS

DPV1 Master

A Profibus communication module interface for CompactLogix controllers. It is developed under license from Rockwell Automation, and incorporates proprietary backplane technology that enables data exchange with CompactLogix processors.

technology.com/Products/Rockwell-Automation-In-chassis/Platform/ CompactLogix/PROFIBUS-DP-V1-Master-Network-Interface-Module-forCompactLogix.

Node Address A unique address identifier for a device assigned to a PROFIBUS network. A

PROFIBUS network can have as many as 126 devices connected on it, where each device on the network must have a unique node address between 1 and 126.

NVS (Non-Volatile Storage) NVS is the permanent memory of a device. Devices such as the adapter and drive

store parameters and other information in NVS so that they are not lost when the device loses power. NVS is sometimes called “EEPROM.”

PowerFlex 523 Drives The Allen-Bradley PowerFlex 523 drives are part of the PowerFlex 520-series of

drives.

PowerFlex 525 Drives The Allen-Bradley PowerFlex 525 drives are part of the PowerFlex 520-series of

drives.

Glossary

PROFIBUS Network A PROFIBUS network uses RS485 to connect devices such as controllers, drives,

motor starters and other equipment in automation systems. A Profibus network can support a maximum of 126 devices. Each device is assigned a unique node address and transmits data on the network at the same data rate. A cable is used to connect devices on the network. It contains the bus signal. Devices can be connected to the network in a daisy-chain connection.

Stop Action When communication is disrupted (for example, a cable is disconnected), the

adapter and drive can respond with a stop action. A stop action results in the drive receiving zero as values for Logic Command, Reference, and Datalink data. If the drive was running and using the Reference from the adapter, it will stay running but at zero Reference.

Studio 5000 Environment The Studio 5000 Engineering and Design Environment combines engineering

and design elements into a common environment. The first element in the Studio 5000 environment is the Logix Designer application. The Logix Designer application is the rebranding of RSLogix 5000 software and will continue to be the product to program Logix 5000 controllers for discrete, process, batch, motion, safety, and drive-based solutions.

The Studio 5000 environment is the foundation for the future of Rockwell Automation engineering design tools and capabilities. It is the one place for design engineers to develop all the elements of their control system.
