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

power from the PowerFlex drive, and then verify power has been discharged before installing or removing a LonWorks 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 the adapter. Failure to comply may result in injury and/or equipment damage.

ATTENTION: Risk of equipment damage exists. The adapter contains ESD (Electrostatic Discharge) sensitive parts that can be

damaged if you do not follow ESD control procedures. Static control precautions are required when handling the adapter. If you are unfamiliar with static control procedures, refer to Guarding Against Electrostatic Damage, Publication 8000-4.5.2.

ATTENTION: Risk of injury or equipment damage exists. If the adapter is transmitting control I/O to the drive, the drive may fault when

you reset the adapter. Determine how your drive will respond before resetting an adapter.

ATTENTION: Risk of injury or equipment damage exists. Parameter 6 - [Comm Flt Action] lets you determine the action of the adapter and

connected drive if communications are disrupted. By default, this parameter faults the drive. You can set this parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does not create a hazard of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable).

ATTENTION: Risk of injury or equipment damage exists. Parameter 7 - [RcvHrtBeat Time] lets you determine how long it will take your

adapter to detect network communication losses. By default, this parameter is set to 120 seconds. You can set it so that the duration is shorter, longer, or disabled. Take precautions to ensure that the setting does 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).

Getting Started 1-5

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

Setting the Comm Fault Action

By default, when communications are disrupted (for example, a cable is disconnected), the drive will remain in its current state (for example, a running drive will continue to run) until Parameter 12 - [RcvHrtBeat Time] has elapsed.

You can configure different responses to communications disruptions using Parameter 06 - [Comm Flt Action] and Parameter 12 -

[RcvHrtBeat Time].

ATTENTION: Risk of injury or equipment damage exists. Parameter 06 - [Comm Flt Action] and Parameter 12 - [RcvHrtBeat Time] let

you determine the action of the adapter and connected drive if communications are disrupted. Take precautions to ensure that the setting of these parameters does 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).

To change the Comm fault action

• Set the value of Parameter 06 - [Comm Flt Action] to the desired

response action.

• Setting Parameter 12 - [RcvHrtBeat Time] to “0” disables the fault

action, and a value greater than “0” enables the fault action. If nviDrvSpeedStpt is not received by the adapter within the

Parameter 12 - [RcvHrtBeat Time] value, the fault action in Parameter 06 - [Comm Flt Action] will be taken.

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

Setting the Idle Fault Action

Parameter 09 - [Idle Flt Action] lets you determine the action of the adapter and connected drive when the node is taken offline.

To change the idle fault action

• Set the value of Parameter 09 - [Idle Flt Action] to the desired

If you set Parameter 06 - [Comm Flt Action] or 09 - [Idle Flt Action] to the “Send Flt Cfg,” the values in the following parameters are sent to the drive after a communications fault and/or idle fault occurs. You must set these parameters to values required by your application.

Parameter Name Description

07 Flt Cfg Logic A 16-bit value sent to the drive for Logic Command.

08 Flt Cfg Ref A 16-bit value (0 – 65535) sent to the drive as a Reference.

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

Resetting the Adapter

Changes to switch settings and some adapter parameters require that you reset the adapter before the new settings take effect. You can reset the adapter by cycling power to the drive or by using the following parameter:

ATTENTION: Risk of injury or equipment damage exists. If the adapter is transmitting control I/O to the drive, the drive may fault when

you reset the adapter. Determine how your drive will respond before resetting a connected adapter.

• Set Parameter 03 - [Reset Module] to Reset Module.

Overview of LonWorks Functionality

A network variable is a data item that a particular device application program expects to get from other devices on a network (Network Variable Inputs) or expects to make available to other devices on a network (Network Variable Outputs). Data exchange on a LonWorks network is handled with Standard Network Variable Types (SNVTs), which represent different types of standard data (for example, temperature, pressure, voltage, etc.).

When a program writes into one of its Network Variable Outputs, the new value of the network variable is propagated across the network to all nodes with Network Variable Inputs connected to that Network Variable Output. A network variable can only be bound to another network variable of the same type.

Specific network variables are described in Network Variable Inputs

(NVIs) on page 4-5, Network Variable Outputs (NVOs) on page 4-7, and Network Configuration Inputs (NCIs)

Important: Any changes made using a PowerFlex 4-Class HIM to a

parameter that is also updated by the network will be overwritten when the next network update occurs.

4-2 Configuring the Network

Operating the Drive Using a LonMark Profile

A LonMark profile defines the functional profile for a node communicating with other nodes. The profile specifies which SNVTs (Standard Network Variable Types) and SCPTs (Standard Configuration Property Types) are used, and provides a semantic meaning about the information being communicated.

When a profile is implemented in a node, it’s called a LonMark object. One node can have several objects implemented. The LonWorks adapter has two objects: a node object and a drive object. The node object (Figure 4.1

Figure 4.1 Node Object

) is used to control the other objects in a node.

Node Operations

This section describes the basics of node operation.

WINK (What is a WINK?)

WINK is a network command that verifies communication with a node. The NET A indicator will flash to indicate that a WINK was received. The LED will flash red according to the following sequence:

• 3 fast flashes

• OFF for 1 second

This sequence is repeated 10 times.

If the Node is Offline

If node is brought offline it will not accept any NVI (Network Variable Inputs) settings or update NVOs (Network Variable Outputs). The adapter uses the setting in Parameter 09 - [Idle Flt Action] and issues a command to the drive. NCI (Network Configuration Input) variable updates will be accepted but not forwarded to the drive until the node goes online and/or is reset.

If the Node is Online

The node accepts NCI and NVI settings and updates NVOs.

Drive Settings to Enable Operation on the Network

Two parameters in PowerFlex 40/400 drives must be set to enable the drive to operate on a LonWorks network:

• Set drive parameter P036 - [Start Source] to “5” (Comm Port)

• Set drive parameter P038 - [Speed Reference] to “5” (Comm Port)

Configuring the Network 4-5

Network Variable Inputs (NVIs)

This section describes the Network Variable Inputs.

Node Object Request

Variable: nviObjRequest

Format: SNVT_obj_request

Explanation: This Network Variable Input enables control commands

and updates from the network to specific objects in the node. The identification number for the node is 0 and for the drive object is 1. The request functionality is the same for both objects. The setting of nviObjRequest does not affect the ability of setting drive speed. The status of the node is reported in nvoObjStatus (page 4-7

Valid Range for Object ID: 0 and 1

Valid Range for Request:

• RQ_UPDATE_STATUS updates nvoObjStatus.

• RQ_CLEAR_STATUS clears nvoObjStatus.

• RQ_CLEAR_ALARM clears a fault in the drive.

• RQ_REPORT_MASK reports supported requests in nvoObjStatus.

• RQ_NORMAL is the normal request where the node functions as

normal.

• RQ_DISABLE puts the node in a disabled state. It sets a Comm Loss Action to the drive (at address 0x2002 bit 5). It does not respond to any updates received on Network Variable Inputs, but it supports writing of configuration properties (Network Configuration Inputs). A value written to a Network Variable Input in this state is not written to the drive. It will NOT be valid when the node is enabled again. In the disabled state, Network Variable Outputs (NVOs) are not propagated to the network. If the node was already in the disabled state, a request to disable the node is not an error.

• RQ_ENABLE enables the node again after a disable request.

All other requests are not supported, and any attempt to use them sets the invalid_request bit in nvoObjStatus.

4-6 Configuring the Network

Drive Speed Setpoint

Variable: nviDrvSpeedStpt

Format: SNVT_switch

Explanation: This Network Variable Input provides a low-resolution

speed setpoint. The setpoint value consists of two elements: the requested speed and the drive state. When the drive state element of the nviDrvSpeedStpt variable is set to zero, the drive will stop.

Val i d Ran g e : 0.0 - 100.0 (in 0.5% increments) followed by a space and either a “0” (STOP), “1” (RUN), or “-1” (AUTO) drive state.

Scaling: See table above and Adjusting the Frequency Setting

page 4-19.

Default Value: -1 (state = AUTO). This value is adapted at power up. This Network Variable Input may use Parameter 12 - [RcvHrtBeat Time] if this function is set up for use.

Speed Setpoint Scaling

Variable: nviDrvSpeedScale

Format: SNVT_lev_percent

Explanation: This Network Variable Input provides scaling for

nviDrvSpdStpt. For example, if nviDrvSpeedStpt value is 100.0% and nviDrvSpeedScale value is -150.000%, then actual speed setpoint value is -150.000% (reverse direction at 1.5 times nominal speed).

The write operation is triggered only when nciGenWriData is updated. The write operation is not triggered if nciGenWriAdr is updated.

ATTENTION: Risk of equipment damage exists. Writing to a parameter using this method causes a Non-Volatile Storage (NVS)

Conditions Required for Operation

This section describes what conditions are required for performing some common actions and how the combination of SNVTs and SCPTs affects the operation of the drive.

Starting the Drive

The drive will RUN if the drive state element in the Network Variable Input nviDrvSpeedStpt is set to “1.”

Stopping the Drive

The drive will stop and use the default stop mode if the drive state element in the Network Variable Input nviSpeedStpt is set to “0.” When the node is brought offline or disabled, the drive will take the idle fault response action set in adapter Parameter 09 - [Idle Flt Action].

Adjusting the Frequency Setting

The actual value written to the drive equals:

nciNmlFreq * (nviDrvSpeedStpt ÷ 100) * (nviDrvSpeedScale ÷ 100)

Explanation: Nominal frequency is the basis for speed setpoint and speed scale percent values. For more information, see Drive Speed

Setpoint on page 4-6 and Speed Setpoint Scaling on page 4-6.

nciMinOutTm versus nciSendHrtBt

The nciMinOutTm has priority over nciSendHrtBt. This means that heartbeats will not be sent as often as specified in nciSendHrtBt if nciMinOutTm has a longer time set.

Error Handling

If nciRcvHrtBt is larger than zero, and heartbeats are not received within the nciRcvHrtBt time, then communication with the LonWorks network is considered disrupted. The adapter response to loss of communication depends on the setting of adapter Parameter 06 - [Comm Flt Action].

Resource Files

LonMark resource files define the components of the external interface for a LonWorks device. These files allow installation tools and operator interface applications to interpret data produced by a device and to correctly format data sent to a device. They also help a system integrator or system operator to understand how to use a device and to control the LonMark objects on a device.

The LonWorks module uses three types of resource files:

• Type File (.TYP) - Defines network variable, configuration property, and enumerated types. LonMark standard network variable and configuration property types are defined in the STANDARD.TYP file. Type files have a .TYP extension.

• Functional Profile Template (.FPT) - Defines functional profiles that are used for describing LonMark objects. A functional profile specifies the mandatory and optional network variable and configuration property components of a LonMark object. LonMark standard functional profiles are defined in the STANDARD.FPT file. Functional profile templates have a .FPT extension.

• Format File (.FMT) - Defines display and input formats for network variable and configuration property types defined in a type file. Formats for the LonMark standard network variable and configuration property types are defined in the STANDARD.FMT file. Format files have a .FMT extension.

In addition to the resource files, these other file types are also used:

• Language File - Defines language-dependent strings. There is a separate language file for each supported language. The supported language file determines the extension of a language file. Two language files are currently available for the LonMark standard type files; these are STANDARD.ENU for American English and STANDARD.ENG for British English.

• XIF File - Defines the external interface for a LonWorks device. This file contains self-documentation information, number of address table entries, number of message tags, and the number, types, and directions of network variables.

The resource files and XIF file are shipped with the LonWorks module on a disk.

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 LonWorks. An adapter reads data on the network and transmits it to the connected drive. It also reads data in the drive and transmits it to the network.

B Binding

A process whereby a Network Variable Input and a Network Variable Output are connected together. Binding a network variable tells the device which other devices it should talk to and what information it should share. Only network variables of the same SNVT type can be bound together. For example, a temperature type could not be bound to a pressure type.

Bus Off

A condition that occurs when an abnormal rate of errors is detected in a device. The bus off device cannot receive or transmit messages on the network. This condition is often caused by corruption of the network data signals due to noise or data rate mismatch.

Glossary

C Channel

The transmission media that connect devices on the network such as twisted pair 78 kbps or power line carrier. Also called segment.

Configuration Property

A data value used to configure the application program in a device.

D Data Rate

The speed at which data is transferred on the network. Each device on a network must be set for the same data rate.

DSI (Drive Serial Interface)

DSI is based on the Modbus RTU serial communication protocol and is used by PowerFlex 4-Class drives.

DSI Peripheral

A device that provides an interface between DSI and a network or user. Peripheral devices are also referred to as “adapters” and “modules.” The

G-2 Glossar y

22-COMM-L, 22-SCM-232 serial converter, and PowerFlex 4-Class HIMs (22-HIM-xxx) are examples of DSI peripherals.

DSI Product

A device that uses the DSI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex 4-Class drive is a DSI product. In this manual, a DSI 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 various Microsoft Windows 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 running on various Microsoft Windows operating systems. This software suite provides a family of tools, including DriveExecutive (version 3.01 or higher), that you can use to program, monitor, control, troubleshoot, and maintain Allen Bradley products. DriveTools SP (version 1.01 or higher) can be used with PowerFlex drives. Information about DriveTools SP can be accessed at http://www.ab.com/drives/drivetools.

E EDS (Electronic Data Sheet) Files

EDS files are simple text files that are used by network configuration tools to describe products so that you can easily commission them on a network. EDS files describe a 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.

Glossary G-3

Fault Configuration

When communication is 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 using specific fault configuration parameters in the adapter. When a fault action parameter is set to use the fault configuration data and a fault occurs, the data from these parameters is sent as the Logic Command and Reference.

Flash Update

The process of updating firmware in the adapter. The adapter can be flash updated using the Allen-Bradley software tool ControlFLASH, the built-in flash capability of DriveExplorer (version 4.01 or higher), or when the adapter is installed in a DSI External Comms Kit, the X-Modem protocol and a 22-SCM-232 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 4-Class drive. PowerFlex 4-Class HIMs (22-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 network connection before the disruption. If the drive was running and using the Reference from the adapter, it will continue to run at the same Reference.

I Interoperability

The ability of systems from different manufacturers and of different types to share information with each other without losing any of their independent functional capabilities and without requiring complex programming by the integrator.

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 produced by the scanner and consumed by the adapter. Input is produced by the adapter and consumed by the scanner.

G-4 Glossar y

L Logic Command/Status

The Logic Command is used to control the PowerFlex drive (for example, start, stop, direction). It consists of one 16-bit word of output to the adapter from the network. The definitions of the bits in this word 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 input from the adapter to the network. The definitions of the bits in this word depend on the drive.

LON

An acronym for local operating network, which consists of intelligent devices, or nodes, that are connected by one or more communications media and that communicate with one another using a common protocol.

LonMaker Software

Windows-based software package for designing, documenting, installing, and maintaining multi-vendor, open, interoperable LonWorks networks.

LonWorks Device

Hardware and software than runs an application and communicates with other devices using the LonWorks protocol. The LonWorks device may optionally interface with input/output hardware. It includes at least one processor and a LonWorks transceiver, and typically has a Neuron Chip.

LonWorks Network

Intelligent devices that communicate with each other using the LonWorks protocol over one or more communications channels.

LonWorks Protocol

The open control networking protocol designed for applications involving sense, monitor, control, and identification functions. It is also known as EIA 709.1 Control Networking Standard and as LonTalk protocol.

N Network Variable

A data item that a particular device application program expects to get from other devices on a network (a Network Variable Input) or expects to make available to other devices on a network (a Network Variable Output). Examples are a temperature, switch value, and actuator position setting.

Glossary G-5

Neuron Chip

A microprocessor usually contained in each LonWorks node which processes all LonTalk protocol messages, senses inputs, manipulates outputs, implements application-specific functions, and stores installation-specific parameters.

Node

An intelligent device connected to the network. Nodes are programmed to send messages to one another in response to changes in various conditions, and to take action in response to messages they receive.

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.”

P PowerFlex 4-Class (Component-Class) Drives

The Allen-Bradley PowerFlex 4-Class (Component-Class) family of drives include the PowerFlex 4, PowerFlex 40, and PowerFlex 400. These drives can be used for applications ranging from 0.2 kW (0.25 HP) to 7.5 kW (10 HP).

Protocols

Rules that order how information is transmitted and presented. An “open protocol” is one in which the manufacturer has made the language “translation” available to anyone who wishes to use it.

R Reference/Feedback

The Reference is used to send a setpoint (for example, speed, frequency, torque) to the drive. It consists of one 16-bit word of output to the adapter from the network.

Feedback is used to monitor the speed of a product. It consists of one 16-bit word of input from the adapter to the network.

S SCPT (Standard Configuration Property Type)

SCPTs are standardized definitions of the units, scaling, encoding, and meaning of the contents of configuration properties.

G-6 Glossar y

SNVT (Standard Network Variable Type)

SNVTs are a set of predefined types of network variables with associated units, such as degrees, centigrade, etc. SNVTs promote interoperability of products from different manufacturers by standardizing the names given to Network Variable Inputs and Network Variable Outputs.

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.

T Transceiver

A device that is both a transmitter and a receiver for a communications channel.

Type 0/Type 1/Type 2 Control

When transmitting I/O, the adapter can use different types of messages for control. The Type 0, Type 1, and Type 2 events help Rockwell Automation personnel identify the type of messages that is used.

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 and Reference data. If the drive was running and using the Reference from the adapter, it will stay running but at zero Reference.
