Safety Precautions

Please read the following safety precautions carefully.

ATTENTION: 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 discharged before installing or removing the option module.

ATTENTION: 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, startup, configuration, and subsequent maintenance of the drive using the option module. Failure to comply may result in injury and/ or equipment damage.

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

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. Rockwell Automation does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

Setting the Node Address Switches

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

Each node on the ControlNet network 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.

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.

Rockwell Automation Publication 750COM-UM003B-EN-P - November 2012 21

Chapter 2 Installing the Option Module

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 this 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).

Using the PowerFlex 20-HIMA6 or 20-HIM-C6S HIM to Access Parameters

Setting the Node Address

If your drive has an enhanced PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, it can be used to access parameters in the option module.

1. Display the Status screen, which is shown on HIM power up.

2. Use the or key to scroll to the Port in which the option

module is installed.

3. Press the PAR# soft key to display the Jump to Param # entry pop-up box.

4. Use the numeric keys to enter the desired parameter number, or use the 

or  soft key to scroll to the desired parameter number.

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 Node Address switches (Figure 1) are set to ‘00’ (Program) the value of Device Parameter 05 - [Net Addr Cfg] determines the node address. When the Node Address switches are in any other combination of positions, these switches determine the node address.

Setting a Master-Slave Hierarchy (Optional)

1. Set the value of Device Parameter 05 - [Net Addr Cfg] to a unique node address.

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 bridge or scanner (1756-CNB, 1756-CNBR, 1747-SCNR, and so forth).

Enable Datalinks To Write Data

on page 31.

The controller output image (controller outputs-to-drive) can have 0 to 16 additional 32-bit parameters (Datalinks). The Datalinks are configured using

Host Parameters 01 - [DL From Net 01] through Parameter 16 - [DL From Net 16]. The number of Datalinks actively used is controlled by the connection

size in the controller. See the respective controller example sections in Chapter 4 for more information on setting the connection size.

26 Rockwell Automation Publication 750COM-UM003B-EN-P - November 2012

IMPORTANT

TIP

Configuring the Option Module Chapter 3

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 will be larger than necessary, which needlessly increases controller response time and memory usage.

When using a ControlLogix controller and an RSLogix 5000 drive Add-On Profile (version 16 or later), there is no need to configure Datalink parameters at this time. They will be assigned when configuring the RSLogix 5000 drive Add-On Profile (see Add the Drive/Option Module to the I/O Configuration

page 39).

When using a ControlLogix controller and the Generic Profile—or a PLC-5 or SLC 500 controller, configure the Datalink parameters now as described in this section.

Host Parameters 01 - [DL From Net 01] through 16 - [DL From Net 16] configure 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:

From Net Parameter Value = (10000 * port number) + (Destination Parameter Number)

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 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 option module; see Resetting the Option Module

3. Since the Logic Command and Reference is 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.

IMPORTANT

TIP

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 Datalinks are configured using Host Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16]. The number of Datalinks actively used is controlled by the connection size in the controller. See the respective controller example sections in Chapter 4 information on setting the connection size.

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.

for more

When using a ControlLogix controller and an RSLogix 5000 drive Add-On Profile, version 16.00 or later, there is no need to configure Datalink parameters at this time. They will be assigned when configuring the RSLogix 5000 drive Add-On Profile (see Add the Drive/Option Module to the I/O

Configuration on page 39).

When using a ControlLogix controller and the Generic Profile—or a PLC-5 or SLC 500 controller, configure the Datalink parameters now as described in this section.

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:

To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number)

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.

Setting a Fault Action

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

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, the CIP Register Object, or the CIP Assembly 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).

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 07 - [Reset Module].

Set Device Parameter 07 - [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 32.)

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

Compatible Keying. The ‘Compatible Keying’ setting for Electronic Keying verifies that the physical module is consistent with the software configuration before the controller and bridge make a connection. Therefore, be sure that you have set the correct revision in this dialog box. See the online Help for additional information on this and other Electronic Keying settings. If keying is not required, select ‘Disable Keying’. Disable Keying is recommended.

When this box is checked, clicking OK opens additional module properties dialog boxes to further configure the bridge. When unchecked, clicking OK closes the bridge’s New Module dialog box. For this example, uncheck this box.

In our example, a 1756-CNBR/D bridge appears under the I/O Configuration folder with its assigned name. For convenience, keep the project open. Later in this chapter the project will need to be downloaded to the controller.

38 Rockwell Automation Publication 750COM-UM003B-EN-P - November 2012

Configuring the I/O Chapter 4

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

• Drive Add-on Profiles (RSLogix 5000 software, version 16.00 or later)

• Drive Generic Profile (RSLogix 5000 software, all versions)

These are described in the following separate sections. If your version of RSLogix 5000 software supports drive Add-on Profiles, we recommend that you use this method.

Using RSLogix 5000 Drive Add-On Profiles, Version 16.00 or Later

When compared to using the Generic Profile (all versions), the RSLogix 5000 drive Add-on Profiles provide the following 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 software, version 16.00 or later, project file (.ACD) and also downloaded to the controller.

• Drive Add-on Profiles, version 2.01 or later, enable I/O to be added online while the controller is in 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 http://www.ab.com/support/

abdrives/webupdate to download the latest RSLogix 5000 drive Add-on

Profile.

Add the Drive/Option Module to the I/O Configuration

To transmit data between the bridge and the drive, you must add the drive as a child device to the parent bridge. In this example, RSLogix 5000 software version

16.00 is used with drive Add-on Profile version 3.01. To determine your drive Add-on Profile version, see Allen-Bradley Knowledgebase document #65882.

1. In the treeview, right-click on the bridge and choose New Module to display the Select Module dialog box.

In our example, we right-click on the 1756-CNBR/D bridge. Expand the Drives group to display all of the available drives with their communication option modules.

•Create Database: Creates a database from an online network drive. Clicking this button displays an RSLinx software RSWho dialog box. Browse to the online drive (for this example, PowerFlex 755), select it, and click OK. The database will be uploaded and stored on the computer. Thereafter, close the Module Definition dialog box and then re-open it to display the new revision.

• Web Update: When a drive is not available online, opens the Allen-Bradley Drives Web Updates website to download a specific database file. After downloading the file, close the Module Definition dialog box and then re-open it to display the new revisio n.

• Match Drive: Use this button when the drive being added to the network matches the drive profile (revision, rating, Datalinks, configuration settings, and so forth) of an existing online network drive. Click this button to conveniently create a duplicate drive profile from the online drive, and automatically load this identical information into the Module Definition dialog box. This eliminates the need to manually enter the information each time a new drive with a matching profile is added to the network.

Compatible Module. The ‘Compatible Module’ setting for Electronic Keying verifies that the physical module is consistent with the software configuration before the controller and bridge make a connection. Therefore, be sure that you have set the correct revision in this dialog box. See the online Help for additional information on this and other Electronic Keying settings.

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. (For example, use Parameters 01, 02, and 03 to configure three Datalinks to write data and/or 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.

choose the parameter to which this Datalink will point (for this example, drive parameter 370 - [Stop Mode A]).

d. Click OK to complete configuration of the Datalink.

The name of the parameter that this Datalink points to is now shown in the row on the Module Definition dialog box.

e. Repeat Steps 6a through 6d for each Datalink being configured.

7. Click OK on the Module Definition dialog box to save the drive and option module configuration, and close the dialog box.

The drive’s New Module dialog box reappears.

8. Click the Connection tab.

9. In the ‘Requested Packet Interval (RPI)’ box, set the value to 5.0

milliseconds or greater (default is 20.0 milliseconds).

This value determines the maximum interval that a controller should use to move data to and from the option module. 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 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.

10. Click OK on the New Module dialog box.

The new node (‘My_PowerFlex_755_Drive’ in this example) now appears under the bridge (‘My_ControlNet_Bridge’ in this example) in the I/O Configuration folder. If you double-click the Controller Tags, you will see that module-defined data types and tags have been automatically created (Figure 6 include the assigned drive parameter name. After you save and download

Using the RSLogix 5000 Generic Profile, All Versions

We recommend that you only use the basic RSLogix 5000 software Generic Profile for any of the following reasons:

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

• Users are already familiar with a Generic Profile and do not want to convert an existing project to a drive Add-on Profile (RSLogix 5000 software, version 16.00 or later).

• A project must maintain specific revision level control.

• The controller cannot be taken offline. RSLogix 5000 software, version

16.00 or later, enables the drive Generic Profile to be added while the controller is online and in the Run mode.

Add the Drive/Option Module to the I/O Configuration

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 ControlNet, 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) in the controller’s I/O image. This basic I/O must always be configured in the ControlNet bridge using RSLogix 5000 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 one 32-bit word for each Datalink to the basic I/O Input Size and/or Output Size.

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 the following :

• How many of the drive’s 32-bit Datalinks (Host DL From Net 01-16 and Host DL To Net 01-16) are used.

• ControlLogix/CompactLogix Controllers only—The drive profile used in RSLogix 5000 software (drive Add-on Profile in version 16.00 or later, or Generic Profile in all versions).

Since the drive Add-on Profile in RSLogix 5000 software, version 16.00 or later, provides descriptive controller tags, the I/O image (tag size and location) is automatically configured based on the drive being used. When using the RSLogix 5000 Generic Profile, however, controller tags are not descriptive or defined.

Using Logic Command/Status

Using Reference/Feedback

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 when using the drive Add-on Profile.

• DINT 1 in the input image when using the Generic Profile.

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

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 when using the drive Add-on Profile.

• DINT 2 in the input image when using the Generic Profile.

D, Logic Command/Status Words: PowerFlex

) and the 32-bit REAL Feedback

When using a drive Add-on Profile, the Reference and Feedback are automatically formatted properly and displayed as a controller tag. When using the Generic Profile, the I/O image is integer-based and the Reference and Feedback are floating point. Because of this, a COP (Copy) instruction or User Defined Data Type (UDDT) is required to correctly write values to the Reference and read values from the Feedback. See the ladder logic program examples in Figure 15

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.

• Parameter 37 - [Maximum Freq] set to 130 Hz.

• Parameter 520 - [Max Fwd Speed] set to 60 Hz.

and Figure 16.

When using the drive Add-on Profile, the controller tags for Reference and Feedback are automatically and properly formatted. This eliminates the need for data conversion using COP (copy) instructions or a UDDT to copy the DINT data into a REAL 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 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 Host Parameters 01…16 - [DL From Net 01-16] and 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

64 Rockwell Automation Publication 750COM-UM003B-EN-P - November 2012

TIP

Using the I/O Chapter 5

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

When using the drive Add-on Profile, the controller tags for Reference and Feedback to Datalinks are automatically and properly formatted.

If a Generic Profile is used, 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 750-Series AC Drives Programming Manual, publication 750-PM001

TIP

IMPORTANT

About Explicit Messaging

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

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.

To message to another device in a different drive port, see the Instance table in Appendix C:

• DPI Parameter Object section on page 115

• Host DPI Parameter Object section on page 129

In the Message Configuration dialog box, set the Instance field to an appropriate value within the range listed for the port in which the device resides.

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.

Figure 18 - Explicit Message Process

➍

Event Description

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

➊

scanner module (download).

The scanner module transmits the Explicit Message Request to the slave device over the network.

➋

The slave device transmits the Explicit Message Response back to the scanner. The data is stored in the

➌

scanner buffer.

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

➍

The Explicit Message is complete.

ControlLogix Controller Examples

To display the Message Configuration dialog box in RSLogix 5000 software, add a message instruction (MSG), create a new tag for the message (Properties:

Base tag type, MESSAGE data type, controller scope), and click the button in the message instruction.

For supported classes, instances, and attributes, see Appendix C, ControlNet Objects.

The explicit messaging examples in this sec tion can be performed with RSLogix 5000 software, any version—or Studio 5000™ Logix Designer application, version 21.00 or later.

The read and write messaging examples in this section are for Device parameters which use Class Code 0x93. For Host parameters, use Class Code 0x9F and format the rest of the message in the same way as these examples.

The Message Configuration has a Service Type of ‘Parameter Read’ which is Class code 0x0F, Parameter Object. Parameter Object is not supported in PowerFlex 750-series drives.

ControlLogix Controller Example Ladder Logic Program to Read a Single Parameter

A Get Attribute Single message is used to read a single parameter. This read message example reads the value of the 32-bit REAL (floating point) parameter 007 - [Output Current] in a PowerFlex 750-Series drive.

Chapter 7 Troubleshooting

Viewing and Clearing Events

The option module has an event queue to record significant events that occur in the operation of the module. 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 with any of these drive configuration tools:

• PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM

• Connected Components Workbench software, version 1.02 or later

• DriveExplorer software, version 6.01 or later

• DriveExecutive software, version 5.01 or later

• Other clients using the DPI Fault object

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

20HIM-UM001

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 option module power cycles and resets. At that point, a new entry replaces the oldest entry. Only an event queue clear operation or the corruption of the EEPROM group containing the event queue will clear the event queue contents. In the latter case, the option module will not generate a fault to indicate that the event queue was corrupted.
