Features

The features of the option module include the following:

• Captive screws to secure and ground the module to the drive.

• Switches to set a node address and network data rate before applying

power to the drive—or you can disable the switches and use option module parameters to configure these functions.

• Compatibility with the following configuration tools to configure the option module and host drive:

– PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM (Human Interface

Module) on the drive, if available

– Connected Components Workbench software, version 1.02 or later – DriveExplorer software, version 6.01 or later – DriveExecutive software, version 5.01 or later

• Status indicators that report the status of the option module and network

communication. They are visible when the drive cover is removed.

• Parameter-configured 32-bit Datalinks in the I/O to meet application requirements (16 Datalinks to write data from the network to the drive, and 16 Datalinks to read data to the network from the drive).

• Explicit Messaging and UCMM (Unconnected Message Manager) support.

• Multiple data exchange methods, including Polled, Cyclic, and Change of State (COS), to transmit data between the network and option module.

• Master-Slave hierarchy that can be configured to transmit data to and from a controller on the network.

• User-defined fault actions to determine how the option module and its connected host drive respond to the following:

– I/O messaging communication disruptions (Comm Flt Action) – Controllers in Idle mode (Idle Flt Action) – Explicit messaging disruptions for drive control via PCCC or the CIP

• Faulted node recovery support. You can configure a device even when it is faulted on the network if you have a configuration tool that uses faulted node recovery and have set the Data Rate switch to position ‘3’. With this configuration, the option module uses parameter settings stored in its nonvolatile storage (NVS) memory for the data rate and node address instead of using its switch settings.

• Access to any PowerFlex drive and its connected peripherals on the network to which the option module is connected.

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

ATTENTION: Risk of injury or equipment damage exists. Host Parameters 33 [Comm Flt Action], 34 - [Idle Flt Action], and 36 - [Msg Flt Action] let you

determine the action of the option module and connected 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 verify 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).

ATTENTION: 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.

ATTENTION: Risk of injury or equipment damage exists. The examples in this publication are intended solely for purposes of example. There are many variables and requirements with any application.

Setting the Node Address Switches

Set the option module Node Address switches (bottom two switches in Figure 1) by rotating the switches to the desired value for each digit.

Each node on the DeviceNet net work must have a unique address. Set the node address before power is applied because the option module uses the node address it detects when it first receives power. To change a node address, you must set the new value and then remove and reapply power to (or reset) the option module, or disconnect and reconnect the DeviceNet network cable.

Configuring and Verifying Key Drive Parameters

The PowerFlex 750-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.

22 Rockwell Automation Publication 750COM-UM002B-EN-P - October 2012

Installing the Option Module Chapter 2

The following steps in this section assume that the drive will receive the Logic Command and Reference from the network.

1. Verify that drive Parameter 301 - [Access Level] is set to ‘1’ (Advanced) or ‘2’ (Expert) to access the required parameters in this procedure.

2. Use drive Parameter 545 - [Speed Ref A Sel] to set the drive speed Reference.

a. Set the Port field to ‘0’ as shown below.

b. Set the Parameter field to point to the port (slot) in which the option

module is installed (for this example, Port 4 Reference). The number ‘874’ in the Parameter field of the example dialog box

above is the parameter in the drive that points to the port.

3. Verify that drive Parameter 930 - [Speed Ref Source] is reporting that the source of the Reference to the drive (Port 0) is the port in which the option module is installed (for example, Port 4 Reference).

This ensures that any Reference commanded from the network can be monitored by using drive Parameter 002 - [Commanded SpdRef]. If a problem occurs, this verification step provides the diagnostic capability to determine whether the drive/option module or the network is the cause.

4. If hard-wired discrete digital inputs are not used to control the drive, verify that all unused digital input drive parameters are set to ‘0’ (Not Used).

For details on viewing and editing parameters, see the PowerFlex 20-HIM-A6/C6S HIM (Human Interface Module) User Manual, publication 20HIM-

UM001.

When the option module Data Rate switch (Figure 2) is set to position ‘3’ (Program), the value of Device Parameter 07 - [Net Addr Cfg] determines the node address. When the Data Rate switch is set to any other position, the Node Address switch settings determine the node address.

We recommend that you do not use node address 63 because all new devices on the network use this address as the default address. Also, node address 63 is used for Automatic Device Recovery (ADR).

1. Set the value of Device Parameter 07 - [Net Addr Cfg] to a unique node address.

2. Reset the option module; see Resetting the Option Module

The NET A status indicator will be steady green or flashing green if the node address is correctly configured, and the option module is connected to an operational network.

Setting a Master-Slave Hierarchy (Optional)

When the option module Data Rate switch (Figure 2) is set to position ‘3’ (Program), the value of Device Parameter 09 - [Net Rate Cfg] determines the data rate. The default setting for this parameter, ‘3’ (Autobaud), will detect the data rate used on the network if another device is setting the data rate. Your application may require a different setting.

1. Set the value of Device Parameter 09 - [Net Rate Cfg] to the data rate at which your network is operating.

2. Reset the option module; see Resetting the Option Module

This procedure is only required if Datalinks are used to write or read data of the drive or its connected peripherals. A hierarchy determines the type of device with which the option module exchanges data. In a Master-Slave hierarchy, the option module exchanges data with a master, such as a scanner (1756-DNB, 1771-SDN, 1747-SDN, and so forth).

on page 32.

Enable Datalinks To Write Data

The controller output image (controller outputs-to-drive) can have 0 to 16 additional 32-bit parameters (Datalinks). The quantity of additional parameters is configured using Device Parameter 02 - [DLs From Net Cfg].

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host Parameters 01, 02, and 03 to configure three Datalinks to write data. Otherwise, the network I/O connection

Host Parameters 01 - [DL From Net 01] through 16 - [DL From Net 16] control which parameters in the drive, option module, or any other connected peripheral receive the values from the network. You can use the PowerFlex 20HIM-A6 or 20-HIM-C6S HIM, or another drive configuration tool such as Connected Components Workbench, DriveExplorer, or DriveExecutive software to select the drive or peripheral by port number and the parameter by name. As an alternate method, the parameter value can be set manually by number using this formula:

For example, suppose you want to use Host Parameter 01 - [DL From Net 01] to write to Parameter 03 of an optional encoder module plugged into drive Port 5. Using the formula, the value for Host Parameter 01 - [DL From Net 01] would be (10000 * 5) + (3) = 50003.

Follow these steps to enable Datalinks to write data.

1. Set the value of Device Parameter 02 - [DLs From Net Cfg] to the number of contiguous controller-to-drive Datalinks that are to be included in the network I/O connection.

2. Reset the option module; see Resetting the Option Module

3. Since the Logic Command and Reference are always used in the option

module, configure the parameters in the drive to accept the Logic Command and Reference from the option module.

When using the controller for speed reference via the option module, set two fields in drive Parameter 545 - [Speed Ref A Sel].

a. Set the Port field for the drive (for example, 0 - PowerFlex 755). b. Set the Parameter field to point to the port in which the option module

is installed (for this example, Port 4 Reference). Also, verify that the mask parameters in the drive (for example,

Parameter 324 - [Logic Mask]) are configured to receive the desired logic from the option module. See the drive documentation for details.

After the above steps are complete, the option module 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 option module. See Chapter 4 Configuring the I/O.

Enable Datalinks To Read Data

The controller input image (drive-to-controller inputs) can have 0 to 16 additional 32-bit parameters (Datalinks). The quantity of additional parameters is configured using Device Parameter 04 - [DLs To Net Cfg].

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host Parameters 17, 18, 19, 20, and 21 to configure five 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 17 - [DL To Net 01] through 32 - [DL To Net 16] configure which parameters in the drive, option module, or any other connected peripheral send the values to the network. You can use the PowerFlex 20-HIM-A6 or 20HIM-C6S HIM, or another drive configuration tool such as Connected Components Workbench, DriveExplorer, or DriveExecutive software to select the drive or peripheral by port number and the parameter by name. As an alternate method, the parameter value can be set manually by number using this formula:

For example, suppose you want to use Host Parameter 17 - [DL To Net 01] to read Parameter 2 of an optional I/O module plugged into drive Port 6. Using the formula, the value for Host Parameter 17 - [DL To Net 01] would be (10000 * 6) + (2) = 60002.

Follow these steps to enable Datalinks to read data.

1. Set the value of Device Parameter 04 - [DLs To Net Cfg] to the number of contiguous drive-to-controller Datalinks that are to be included in the network I/O connection.

Selecting COS, Cyclic, or Polled Data Exchange

2. Reset the option module; see Resetting the Option Module

The option module is configured to send output data to the master (controller). You must now configure the controller to recognize and transmit I/O to the option module. See Chapter 4

The data exchange is the method that the option module uses to exchange data on the DeviceNet network. Polled is the default and is recommended—unless one of the other following data exchanges, which the adapter supports, is more appropriate for your application:

• COS (Change of State) • Polled and COS

• Cyclic • Polled and Cyclic

• Polled

If ‘Polled and COS’ or ‘Polled and Cyclic’ is used, the option module transmits and receives the I/O from the polled messages. It transmits only a Logic Status and Feedback in COS or Cyclic messages. Other data is transmitted in Polled messages.

Setting a Fault Action

By default, when communication is disrupted (for example, the network cable is disconnected), the controller is idle (in program mode or faulted), or explicit messaging for drive control is disrupted, the drive responds by faulting if it is using I/O from the network. You can configure a different response to these faults:

• Disrupted I/O communication by using Host Parameter 33 - [Comm Flt Action].

• An idle controller by using Host Parameter 34 - [Idle Flt Action].

• Disrupted explicit messaging for drive control via PCCC or the CIP Register Object by using Host Parameter 36 - [Msg Flt Action].

ATTENTION: Risk of injury or equipment damage exists. Host Parameters 33 [Comm Flt Action], 34 - [Idle Flt Action], and 36 - [Msg Flt Action] let you

determine the action of the option module and connected drive if 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 verify 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 network cable, controller in idle state, or explicit message control disruption).

Changing the Fault Action

Set the values of Host Parameters 33 - [Comm Flt Action], 34 - [Idle Flt Action], and 36 - [Msg Flt Action] to an action that meets your application

requirements.

Value Action Description

0 Fault The drive is faulted and stopped. (Default)

1 Stop The drive is stopped, but not faulted.

2 Zero Data The drive is sent ‘0’ values for 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 data that you set in the fault configuration parameters (Host

Parameters 37 - [Flt Cfg Logic], 38 - [Flt Cfg Ref], and 39 - [Flt Cfg DL 01] through 54 - [Flt Cfg DL 16]).

Setting the Fault Configuration Parameters

When setting Host Parameter 33 - [Comm Flt Action], 34 - [Idle Flt Action] or 36 - [Msg Flt Action] to ‘Send Flt Cfg’, the values in the following parameters are sent to the drive after a communication fault, idle fault, and/or explicit messaging for drive control fault occurs. You must set these parameters to values required by your application.

Option Module Host Parameter Description

Parameter 37 - [Flt Cfg Logic] A 32-bit value sent to the drive for Logic Command.

Parameter 38 - [Flt Cfg Ref] A 32-bit REAL (floating point) value sent to the drive for Reference.

Parameter 39 - [Flt Cfg DL 01]

through

Parameter 54 - [Flt Cfg DL 16]

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

A 32-bit integer value sent to the drive for a Datalink. If the destination of the datalink is a REAL (floating point) parameter, you must convert the desired value to the binary representation of the REAL value. (An internet search of ‘hex to float’ provides a link to a tool to do this conversion.)

Resetting the Option Module

Changes to switch settings and some option module parameters require you to reset the option module before the new settings take effect. You can reset the option module by power cycling the drive or by using Device Parameter 14 - [Reset Module].

Set Device Parameter 14 - [Reset Module] to ‘1’ (Reset Module).

When you enter ‘1’ (Reset Module), the option module will be immediately reset. An alternate method to reset the module is by power cycling the drive. When you enter ‘2’ (Set Defaults), the option module will set all of its Device and Host parameters to their factory default values. (This is the same as pressing the ALL soft key when using the MEMORY folder method described in Restoring Option

Module Parameters to Factory Defaults on page 33.)

When performing a Set Defaults, 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, 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).

If your application allows, you can also reset the option module by cycling power to the drive (resetting the drive) or by using the HIM’s Reset Device function located in the drive’s DIAGNOSTIC folder.

Restoring Option Module Parameters to Factory Defaults

As an alternate reset method, you can restore the option module parameters by using a MEMORY folder menu item instead of using Device Parameter 14 - [Reset Module] described in Resetting the Option Module MEMORY folder method provides two ways to restore the option module

Device and Host parameters:

• ALL—restores ALL option module Device and Host parameters to their

factory default values.

• MOST—restores MOST option module Device and Host parameters— except the following which are used for network setup:

– Device Parameter 07 - [Net Addr Cfg] – Device Parameter 09 - [Net Rate Cfg]

Follow these steps to restore option module Device and Host parameters to their factory default values.

Configuring the I/O

This chapter provides instructions on how to configure a Rockwell Automation ControlLogix controller to communicate with the option module and connected PowerFlex drive.

Top ic Pa ge

Using RSLinx Classic Software

ControlLogix Controller Example

Because the option module and PowerFlex 750-Series drive are 32-bit devices, the ControlLogix controller (also a 32-bit device) is used for example purposes in this chapter and throughout this manual. To simplify configuration and ladder logic programs, and to maximize drive performance, we recommend using only a 32-bit platform Logix controller with this option module and PowerFlex 750-Series drive. If you must use a 16-bit controller (PLC-5, SLC 500, or MicroLogix 1100/1400), we recommend using a 20-COMM-D adapter and 20-750-20COMM or 20-750-20COMM-F1 Communication Carrier Card installed in drive Port 4, 5 or 6. In this case, go to the Rockwell Automation Technical Support Knowledgebase website at www.rockwellautomation.com/

knowledgebase for details to configure and use the I/O, and configure explicit

messaging.

Using RSLinx Classic Software

Rockwell Automation Publication 750COM-UM002B-EN-P - October 2012 37

RSLinx Classic software, in all its variations (Lite, Gateway, OEM, and so forth), is used to provide a communication link between the computer, network, and controller.

Use the 20-HIM-A6 or 20-HIM-C6S HIM, or another drive configuration tool such as Connected Components Workbench, DriveExplorer, or DriveExecutive software to view Diagnostic Items 7 and 8. The option module automatically calculates the number of bytes for the Input Size and Output Size based on the values of Device Parameters 2 - [DLs From Net Cfg] and 4 - [DLs To Net Cfg] configured in Setting a Master-Slave Hierarchy (Optional)

Calculate the Input/Output Byte Sizes

You can easily calculate the number of bytes for the Input Size and Output Size. Since the option module always uses the 32-bit Logic Command, 32-bit Feedback, 32-bit Logic Status, and 32-bit Reference, at least 8 bytes must be set for both the Input Size and Output Size. (A 32-bit word is four bytes.) If any or all of the drive’s sixteen 32-bit Datalinks are used (see Setting a Master-Slave Hierarchy (Optional)

page 27), increase the Input and Output Size settings accordingly.

•Input Size: Multiply the number of Datalinks used to write data (value of Device Parameter 02 - [DLs From Net Cfg]) by 4 bytes, and add this result to the minimum 8 bytes. For example, if Parameter 02 has a value of ‘3’, add 12 bytes (3 x 4 bytes) to the required minimum 8 bytes for a total of 20 bytes.

•Output Size: Multiply the number of Datalinks used to read data (value of Device Parameter 04 - [DLs To Net Cfg]) by 4 bytes, and add this result to the minimum 8 bytes. For example, if Parameter 04 has a value of ‘7’, add 28 bytes (7 x 4 bytes) to the required minimum 8 bytes for a total of 36 bytes.

About I/O Messaging

ATTENTION: Risk of injury or equipment damage exists. The examples in this

publication are intended solely for purposes of example. There are many variables and requirements with any application. Rockwell Automation does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

On CIP-based networks, including DeviceNet, 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 750-Series drives.

The option module includes the Logic Command, Logic Status, Reference, and Feedback (all as 32-bit words). This requires 8 bytes for the Input Size and 8 bytes for the Output Size in the controller’s I/O image. This basic I/O must always be configured in the DeviceNet scanner using RSNetWorx for DeviceNet software. Additional I/O, if needed, can be set using up to 16 Datalinks to write data and/or up to 16 Datalinks to read data. When using any combination of these Datalinks, add 4 bytes for each Datalink to the basic I/O Input Size and/or Output Size.

Chapter 3

Configuring the I/O, discuss how to configure the option module 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 option module and controller.

Chapter 5 Using the I/O

Understanding the ControlLogix Controller 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 option module. Input I/O is status data that is produced by the option module and consumed as input by the controller. The I/O image will vary based on how many of the drive’s 32-bit Datalinks (Host DL From Net 01-16 and Host DL To Net 01-16) are used.

If all available I/O is not used, the image is truncated. The image always uses consecutive words starting at word 0.

Using Logic Command/Status

The Logic Command is a 32-bit word of control data produced by the controller and consumed by the option module. The Logic Status is a 32-bit word of status data produced by the option module and consumed by the controller.

When using a ControlLogix controller, the Logic Command word is always DINT 0 in the output image and the Logic Status word is always DINT 0 in the input image.

This manual contains the bit definitions for compatible products available at the time of publication in Appendix 750-Series Drives.

Using the I/O Chapter 5

Using Reference/Feedback

The Reference is a 32-bit REAL (floating point) piece of control data produced by the controller and consumed by the option module. The Feedback is a 32-bit REAL (floating point) piece of status data produced by the option module and consumed by the controller.

When using a ControlLogix controller, the 32-bit REAL Reference word is always DINT 1 in the output image (see Ta b l e 2 word is always DINT 1 in the input image. Because the I/O image is integerbased and the Reference and Feedback are floating point, a COP (Copy) instruction or User Defined Data Types (UDDT) is required to correctly write values to the Reference and read values from the Feedback. See the ladder logic program examples in Figure 9

The Reference and Feedback 32-bit REAL values represent drive speed. The scaling for the speed Reference and Feedback is dependent on drive Parameter 300 - [Speed Units]. For example, if Parameter 300 is set to Hz, a 32-bit REAL Reference value of ‘30.0’ would equal a Reference of 30.0 Hz. If Parameter 300 is set to RPM, a 32-bit REAL Reference value of ‘1020.5’ would equal a Reference of 1020.5 RPM. Note that the commanded maximum speed can never exceed the value of drive Parameter 520 - [Max Fwd Speed]. Ta b l e 3 References and their results for a PowerFlex 750-Series drive that has its:

• Parameter 300 - [Speed Units] set to Hz.

the drive documentation for details. (2) For this example, drive parameter 300 - [Speed Units] is set to Hz. (3) The drive runs at 60 Hz instead of 130 Hz or 65 Hz because drive Parameter 520 - [Max Fwd Speed] sets 60 Hz as the maximum

speed.

Chapter 5 Using the I/O

IMPORTANT

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 32-bit word in a ControlLogix controller.

The following rules apply when using PowerFlex 750-Series drive Datalinks:

• The target of a Datalink can be any Host parameter, including those of a peripheral. For example, drive parameter 535 - [Accel Time 1] can be the target of any or all option modules installed in the drive.

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

Device Parameter 02 - [DLs From Net Cfg] Device Parameter 04 - [DLs To Net Cfg] Host Parameters 01…16 - [DL From Net 01-16] Host Parameters 17…32 - [DL To Net 01-16]

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

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

• When you use a Datalink to change a value, the value is not written to the Nonvolatile Storage (NVS) memory. 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 750-Series drive peripherals (the embedded EtherNet/ IP adapter on PowerFlex 755 drives only, and option modules such as an encoder or 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 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 doing the following:

• Inhibiting the module in RSLogix 5000 software

• Putting the controller in Program mode

• Placing the scanner in idle mode

• Disconnecting the drive from the network

DeviceLogix Datalinks are also locked while the DeviceLogix program is running. The DeviceLogix program must first be disabled to allow changes to the

Using the I/O Chapter 5

TIP

Datalinks. Set DeviceLogix parameter 53 - [DLX Operation] to ‘DisableLogic’ to disable the logic (the parameter value will then change to ‘LogicDisabld’).

A COP (Copy) instruction or a UDDT is needed—for REAL parameters, speed Reference, and speed Feedback only—to copy the DINT data into a REAL word for input data conversion. For output data conversion, a COP (Copy) instruction or UDDT is needed—for REAL parameters, speed Reference, and speed Feedback only—to copy the REAL data into a DINT word. To determine whether a parameter is a 32-bit integer (DINT) or a REAL data type, see the Data Type column in the chapter containing parameters in the PowerFlex 750Series AC Drives Programming Manual, publication 750-PM001

Example Ladder Logic Program Information
