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 removed before installing or removing a ControlNet adapter.
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, start-up, configuration, and subsequent maintenance of the product using a
ControlNet adapter. Failure to comply may result in injury and/or equipment damage.
ATTENTION: Risk of equipment damage exists. The ControlNet 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, refer to Guarding Against
Electrostatic Damage, Publication 8000-4.5.2.
ATTENTION: Risk of injury or equipment damage exists. If the
ControlNet 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 an adapter.
ATTENTION: Risk of injury or equipment damage exists.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action] let you determine the action of the adapter and connected PowerFlex drive if communications are disrupted. By default, these parameters fault the
PowerFlex drive. You can set these parameters so that the PowerFlex drive continues to run. 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 faulted controller.)
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.

Preparing for an Installation
Before installing the ControlNet adapter:
• Verify that you have all required equipment. Refer to
.
Commissioning the Adapter
To commission the adapter, you must set a unique node address on the
network. (Refer to the Glossary
for details about node addresses.)
Important: New settings are recognized only when power is applied to the adapter, or the adapter is reset. If you change a setting, cycle power or reset the adapter.
!
ATTENTION: Risk of equipment damage exists. The ControlNet 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, refer to Guarding Against
Electrostatic Damage, Publication 8000-4.5.2.
Important: To guard against device malfunction, you must wear a grounding wrist strap when installing the ControlNet adapter.
2-2
Installing the Adapter
1. Set the ControlNet adapter’s node address by rotating the node address switches to the desired value for each digit.
Important: Each node on the ControlNet network must have a unique address.
Important: The node address must be set before power is applied because the adapter 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 adapter.

Configuring the Adapter
Setting a Fault Action
By default, when communications are disrupted (for example, a cable is disconnected) or the scanner is idle, the drive responds by faulting if it is using I/O from the network. You can configure a different response to communication disruptions using Parameter 10 - [Comm Flt Action] and a different response to an idle scanner using Parameter 11 - [Idle
Flt Action].
!
ATTENTION: Risk of injury or equipment damage exists. Parameters
10 - [Comm Flt Action] and 11 - [Idle Flt Action] let you determine the action of the adapter and connected drive if communications are disrupted or the scanner is idle. By default, these parameters fault the drive. You can set these parameters so that the drive continues to run.
Some ControlNet scanners may operate differently when a controller is idle which could limit the Idle Fault Action’s operating states.
Precautions should be taken to ensure that 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 faulted controller).
To change the fault action
• Set the values of Parameters 10 - [Comm Flt Action] and 11- [Idle
Flt Action] to the desired responses:

About I/O Messaging
On ControlNet, I/O messaging is 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 drives.
The ControlNet adapter provides many options for configuring and using
I/O, including:
• The size of I/O can be configured by enabling or disabling the Logic
Command/Reference and Datalinks.
• A Master-Slave hierarchy can be set up.
Chapter 3 , Configuring the Adapter and
Configuration for PLC-5C Applications
discuss how to configure the
adapter and scanner on the network for these options. The Glossary
defines the different options. This chapter discusses how to use I/O after you have configured the adapter and scanner.

PLC-5C Applications
Understanding the I/O Image
The terms input and output are defined from the scanner’s point of view.
Therefore, Output I/O is data that is output from the scanner and consumed by the ControlNet adapter. Input I/O is status data that is produced by the adapter and consumed as input by the scanner. The I/O image table will vary based on the following:
• Size (either 16-bit or 32-bit) of the Reference/Feedback words and
Datalink words used by the drive.
• Configuration of I/O (Parameter 25 - [M-S Input] and Parameter
26 - [M-S Output]). If all I/O is not enabled, the image table is truncated. The image table always uses consecutive words starting at word 0.

LSW is Least Significant Word (Bits 15 – 0). MSW is Most Significant Word (Bits 31 – 16).
Using Logic Command/Status
When enabled, the Logic Command/Status word is always word 0 in the output image and word 0 in the input image. The Logic Command is a
16-bit word of control produced by the scanner and consumed by the adapter. The Logic Status is a 16-bit word of status produced by the adapter and consumed by the scanner.
This manual contains the bit definitions for select PowerFlex products in
Appendix D , Logic Command/Status Words . For other products, refer to
their documentation.

Using Reference/Feedback
When enabled, Reference/Feedback begins at word 1 (16-bit) or word 2
(32-bit) in the I/O range. The Reference (16 bits or 32 bits) is produced by the controller and consumed by the adapter. The Feedback (16 bits or
32 bits) is produced by the adapter and consumed by the controller. The size of the Reference/Feedback is determined by the drive and displayed in Parameter 07 - [Ref/Fdbk Size] in the adapter.
Size Valid Values In I/O Image Example
16-bit -32768 to 32767 Word 1
32-bit -2147483648 to 2147483647 Word 2 (LSW) and Word 3 (MSW)
The Reference value is a scaled value; it is not an engineering value. For example, in PowerFlex 70/700 drives, the reference is scaled based on the value of Parameter 55 - [Maximum Freq] where “32,767” equals the Parameter 55 frequency value, and “0” equals 0 Hz. Note that the commanded maximum speed can never exceed the value of Parameter
82 - [Maximum Speed].
shows example References and their results on a PowerFlex 70/700 drive that has its Parameters 55 -
[Maximum Freq] set to 130 Hz and 82 - [Maximum Speed] set to 60
Hz.

A value of 32767 is equivalent to the Parameter 55 frequency value. The effects of values greater than 32767 depend on whether the DPI host uses a bipolar or unipolar direction mode. Refer to the documentation for your DPI host.
(2)
The drive runs at 60 Hz instead of 130 Hz or 65 Hz because Parameter 82 - [Maximum
Speed] sets 60 Hz as the maximum speed.
(3)
The Feedback value is also scaled based on the value of Parameter 55 - [Maximum
Freq], For example, 60/130 = 0.46 so 32767 x 0.46 = 15123.
For Reference/Feedback details about other DPI Hosts, refer to their respective User Manuals.

Using Datalinks
A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks allow a parameter value to be changed without using an Explicit Message. When enabled, each Datalink occupies two 16-bit or 32-bit words in both the input and output image.
Parameter 08 - [Datalink Size] will indicate whether the drive uses
16-bit or 32-bit words for Datalinks.
Rules for Using Datalinks
• Each set of Datalink parameters in a PowerFlex drive can be used by only one adapter. If more than one adapter is connected to a single drive, multiple adapters must not try to use the same Datalink.
• Parameter settings in the drive determine the data passed through the
Datalink mechanism. Refer to the documentation for your drive.
• 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.
32-Bit Parameters using 16-Bit Datalinks
To read (and/or write) a 32-bit parameter using 16-bit Datalinks, typically both Datalinks of a pair (A, B, C, D) are set to the same 32-bit parameter. For example, to read Parameter 09 - [Elapsed MWh] in a
PowerFlex 70, both Datalink A1 and A2 are set to “9.” Datalink A1 will contain the least significant word (LSW) and Datalink A2 will contain the most significant word (MSW). In this example, the Parameter 9 value of 5.8 MWh is read as a “58” in Datalink A1.

Regardless of the Datalink combination, x1 will always contain the LSW and x2 will always contain the MSW. In the following examples

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 ControlNet network.
Performing Explicit Messages
There are five basic events in the Explicit Messaging process. The details of each step will vary depending on the controller. Refer to the documentation for your controller.
Important: There must be a request message and a response message for all Explicit Messages, whether you are reading or writing data.

1. You format the required data and set up the ladder logic program to send an Explicit Message request to the scanner module (download).
2. The scanner module transmits the Explicit Message Request to the slave device over the ControlNet network.
3. The slave device transmits the Explicit Message Response back to the scanner. The data is stored in the scanner buffer.
4. The controller retrieves the Explicit Message Response from the scanner’s buffer (upload).
5. The Explicit Message is complete.
Note: The scanner module may be integrated with the controller (e.g.,
PLC-5C).
PLC-5C Applications
5-13
The ControlNet I/O Transfer (CIO) instruction is used to send Explicit
Messages. For PLC-5C controllers before Series F Revision C, the available services you should use are Get Attribute Single, Get Attribute
All, Set Attribute Single, or Set Attribute All. Series F Revision C (or later) allow for more complex messages using a new Generic
Bi-Directional communication command.

Understanding the I/O Image
The terms input and output are defined from the scanner’s point of view.
Therefore, Output I/O is data that is output from the scanner and consumed by the ControlNet adapter. Input I/O is status data that is produced by the adapter and consumed as input by the scanner. The I/O image table will vary based on the following:
• Size (either 16-bit or 32-bit) of the Reference/Feedback words and
Datalink words used by the drive.
• Configuration of I/O (Parameter 25 - [M-S Input] and Parameter
26 - [M-S Output]). If all I/O is not enabled, the image table is truncated. The image table always uses consecutive words starting at word 0.
Figure 6.21
illustrates an example of an I/O image with 16-bit words.

ControlLogix Applications
Using Logic Command/Status
When enabled, the Logic Command/Status word is always word 0 in the output image and word 2 in the input image. The Logic Command is a
16-bit word of control produced by the scanner and consumed by the adapter. The Logic Status is a 16-bit word of status produced by the adapter and consumed by the scanner.
This manual contains the bit definitions for select PowerFlex products in
Appendix D , Logic Command/Status Words . For other products, refer to
their documentation.
Using Reference/Feedback
When enabled, Reference/Feedback begins at word 1 (16-bit) or word 2
(32-bit) in the I/O range. The Reference (16 bits or 32 bits) is produced by the controller and consumed by the adapter. The Feedback (16 bits or
32 bits) is produced by the adapter and consumed by the controller. The size of the Reference/Feedback is determined by the drive and displayed in Parameter 07 - [Ref/Fdbk Size] in the adapter.
Size Valid Values In I/O Image Example
16-bit -32768 to 32767 Word 1 Figure 6.21
32-bit -2147483648 to 2147483647 Word 2 (LSW) and Word 3 (MSW) Figure 6.22
The Reference value is a scaled value; it is not an engineering value. For example, in PowerFlex 70/700 drives, the reference is scaled based on the value of Parameter 55 - [Maximum Freq] where “32,767” equals the Parameter 55 frequency value, and “0” equals 0 Hz. Note that the commanded maximum speed can never exceed the value of Parameter
82 - [Maximum Speed]. Figure 6.23
shows example References and their results on a PowerFlex 70/700 drive that has its Parameters 55 -
[Maximum Freq] set to 130 Hz and 82 - [Maximum Speed] set to 60
Hz.

A value of 32767 is equivalent to the Parameter 55 frequency value. The effects of values greater than 32767 depend on whether the DPI host uses a bipolar or unipolar direction mode. Refer to the documentation for your DPI host.
(2)
The drive runs at 60 Hz instead of 130 Hz or 65 Hz because Parameter 82 - [Maximum
Speed] sets 60 Hz as the maximum speed.
(3)
The Feedback value is also scaled based on the value of Parameter 55 - [Maximum
Freq], For example, 60/130 = 0.46 so 32767 x 0.46 = 15123.
For Reference/Feedback details about other DPI Hosts, refer to their respective User Manuals.
Using Datalinks
A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks allow a parameter value to be changed without using an Explicit Message. When enabled, each Datalink occupies two 16-bit or 32-bit words in both the input and output image.
Parameter 08 - [Datalink Size] will indicate whether the drive uses
16-bit or 32-bit words for Datalinks.
Rules for Using Datalinks
• Each set of Datalink parameters in a PowerFlex drive can be used by only one adapter. If more than one adapter is connected to a single drive, multiple adapters must not try to use the same Datalink.
• Parameter settings in the drive determine the data passed through the
Datalink mechanism. Refer to the documentation for your drive.
• 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.
6-18
ControlLogix Applications
32-Bit Parameters using 16-Bit Datalinks
To read (and/or write) a 32-bit parameter using 16-bit Datalinks, typically both Datalinks of a pair (A, B, C, D) are set to the same 32-bit parameter. For example, to read Parameter 09 - [Elapsed MWh] in a
PowerFlex 70, both Datalink A1 and A2 are set to “9.” Datalink A1 will contain the least significant word (LSW) and Datalink A2 will contain the most significant word (MSW). In this example, the Parameter 9 value of 5.8 MWh is read as a “58” in Datalink A1.

Regardless of the Datalink combination, x1 will always contain the LSW and x2 will always contain the MSW. In the following examples

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 ControlNet network.
Performing Explicit Messages
There are five basic events in the Explicit Messaging process. The details of each step will vary depending on the controller. Refer to the documentation for your controller.
Important: There must be a request message and a response message for all Explicit Messages, whether you are reading or writing data.

Glossary
A
Adapter
Devices such as drives, controllers, and computers usually require an adapter to provide a communication interface between them and a network such as ControlNet. 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 ControlNet adapter (20-COMM-C or 20-COMM-Q) connects
PowerFlex drives to a ControlNet network. Adapters are sometimes also called “cards,” “embedded communication options,” “gateways,”
“modules,” and “peripherals.”
C
CAN (Controller Area Network)
A CAN is a serial bus protocol on which DPI is based.
Controller
A controller, also called programmable logic controller, is a solid-state control 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 Scanner.
ControlFLASH
ControlFLASH is an Allen-Bradley software tool that lets users electronically update firmware on printed circuit boards. The tool takes advantage of the growing use of flash memory (electronic erasable chips) across industrial control products.
ControlNet
An open producer-consumer communication network with features, such as redundant medial and deterministic I/O timing, designed for high-performance or time-critical requirements.
D
Data Rate
The data rate is the speed at which data is transferred on the ControlNet network (fixed at 5M bit/s).
Datalinks
A Datalink is a type of pointer used by some PowerFlex drives to transfer data to and from the controller. Datalinks allow specified
G-2
Glossary parameter value(s) to be accessed or changed without using explicit messages. When enabled, each Datalink consumes either four bytes or eight bytes in both the input and output image table of the controller. The drive determines the size of Datalinks.
DPI (Drive Peripheral Interface)
DPI is a second generation peripheral communication interface used by various Allen-Bradley drives and power products, such as PowerFlex 70 and PowerFlex 700 drives. It is a functional enhancement to SCANport.
DPI Peripheral
A device that provides an interface between DPI and a network or user.
Peripheral devices are also referred to as “adapters” and “modules.” The
20-COMM-C or 20-COMM-Q adapter and PowerFlex 7-Class HIMs
(20-HIM-xxx) are examples of DPI peripherals.
DPI Product
A device that uses the DPI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex 7-Class drive is a DPI product. In this manual, a DPI product is also referred to as “drive” or “host.”
DriveExplorer Software
DriveExplorer software is a tool for monitoring and configuring
Allen-Bradley products and adapters. It can be run on computers running
Microsoft Windows 95, Windows 98, Windows NT (version 4.0 or higher), Windows 2000, and Windows CE (version 2.01 or higher) operating systems. DriveExplorer (version 3.xx or higher) can be used to configure this adapter and PowerFlex drives. Information about
DriveExplorer software and a free lite version can be accessed at http:// www.ab.com/drives/driveexplorer.
DriveTools SP Software
A software suite designed for Microsoft Windows 98, Windows NT (4.0 or higher), and Windows 2000 operating systems. This software suite provides a family of tools that you can use to program, monitor, control, troubleshoot, and maintain Allen-Bradley products. DriveTools SP
(version 1.xx) can be used with PowerFlex drives. Information about
DriveTools SP can be accessed at http://www.ab.com/drives/drivetools.
E
Electronic Data Sheet (EDS) Files
EDS files are simple text files that are used by network configuration tools such as RSNetWorx for ControlNet to describe products so that you can easily commission them on a network. EDS files describe a
Glossary
G-3
product device type, revision, and configurable parameters. EDS files for many Allen-Bradley products can be found at http://www.ab.com/ networks/eds.
Explicit Messaging
Explicit Messages are used to transfer data that does not require continuous updates. They are typically used to configure, monitor, and diagnose a device over the network.
F
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 scanner 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 PowerFlex drive can respond with a user-defined fault configuration. The user sets the data that is sent to the drive in the fault configuration parameters (Parameters 15- [Flt Cfg
Logic] through 24- [Flt Cfg D2 In]). When a fault action parameter is set to use the fault configuration and a fault occurs, the data from these parameters is sent as the Logic Command, Reference, and/or
Datalink(s).
Flash Update
The process of updating firmware in the adapter. The adapter can be flash updated using the ControlFLASH tool or the X-modem protocol and a 1203-SSS Smart Self-powered Serial converter (version 3.xx or higher firmware).
H
HIM (Human Interface Module)
A device that can be used to configure and control a PowerFlex 7-Class drive. PowerFlex 7-Class HIMs (20-HIM-xxx) can be used to configure connected peripherals.
Hold Last
When communications are disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond by holding last. Hold last results in the drive receiving the last data received via the
ControlNet 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.
G-4
Glossary
I
I/O Data
I/O data, sometimes called “implicit messages” or “input/output,” transmit time-critical data such as a Logic Command and Reference. The terms “input” and “output” are defined from the scanner’s point of view.
Output is transmitted by the scanner and consumed by the adapter. Input is transmitted by the adapter and consumed by the scanner.
L
Logic Command/Logic Status
The Logic Command is used to control the PowerFlex drive (e.g., start, stop, direction). It consists of one 16-bit word of input to the adapter from the network. The definitions of the bits in this word depend on the drive.
The Logic Status is used to monitor the PowerFlex drive (for example, operating state, motor direction). It consists of one 16-bit word of output from the adapter to the network. The definitions of the bits in this word depend on the drive.
M
Master-Slave Hierarchy
An adapter configured for a master-slave hierarchy exchanges data with the master device. Usually, a network has one scanner which is the master device, and all other devices (for example, drives connected to
ControlNet adapters) are slave devices.
On a network with multiple scanners (called a multimaster hierarchy), each slave device must have a scanner specified as its master.
N
Node Address
The legal range of ControlNet addresses is 1-99. The ControlNet adapter includes two rotary switches to allow the ControlNet address to be set.
The ControlNet adapter reads the values of the switches only at power-up.
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.”
Glossary
G-5
P
PCCC (Programmable Controller Communications Command)
PCCC is the protocol used by some controllers to communicate with devices on a network. Some software products (for example,
DriveExplorer and DriveTools SP) also use PCCC to communicate.
Ping
A ping is a message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control.
PowerFlex 7-Class Drives
The Allen-Bradley PowerFlex 7-Class family of drives includes
PowerFlex 70, PowerFlex 700, PowerFlex 700S, and PowerFlex 7000 drives. These drives can be used for applications ranging from 0.37 kW
(0.5 HP) to 3,000 kW (4,000 HP). All PowerFlex 7-Class drives support
DPI, allowing them to use the ControlNet adapter (20-COMM-C or
20-COMM-Q). This manual focuses on using the adapter with
PowerFlex 7-Class drives. Other products that implement DPI can also use the adapter.
R
Reference/Feedback
The Reference is used to send a Reference (for example, speed, frequency, torque) to the drive. It consists of one word of input to the adapter from the network. The size of the word (either a 16-bit word or
32-bit word) is determined by the drive.
Feedback is used to monitor the speed of the drive. It consists of one word of output from the adapter to the network. The size of the word
(either a 16-bit word or 32-bit word) is determined by the drive.
RSLogix
RSLogix software is a tool for configuring and monitoring controllers to communicate with connected devices. It is a 32-bit application that runs on various Windows operating systems. Information about RSLogix software can be found at http://www.software.rockwell.com/rslogix.
RSNetWorx for ControlNet
RSNetWorx for ControlNet software is a tool for configuring and monitoring ControlNet networks and connected devices. It is a 32-bit
Windows application that runs on Microsoft Windows 95, Windows 98, and Windows NT. Information about RSNetWorx for ControlNet software can be found at http://www.software.rockwell.com/rsnetworx.
G-6
Glossary
S
Scanner
A scanner is a separate module (of a multi-module controller) or a built-in component (of a single-module controller) that provides communication with adapters connected to a network. See also
Controller.
Status Indicators
Status indicators are LEDs that are used to report the status of the adapter, network, and drive. They are on the adapter and can be viewed on the front cover of the drive when the drive is powered.
Z
Zero Data
When communications are disrupted (for example, a cable is disconnected), the adapter and drive can respond with zero data. Zero data 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.
