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 an 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 an adapter. Failure to comply may result in injury and/or equipment damage.

ATTENTION: Risk of equipment damage exists. The adapter 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 adapter. 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. DPI or SCANport host products must not be directly connected together using 1202 cables. Unpredictable behavior due to timing and other internal procedures can result if two or more devices are connected this way.

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. Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]

let you determine the action of the adapter and connected drive if I/O communication is disrupted or the controller is idle. By default, these parameters fault the drive. You can set 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 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.

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.

2-2 Installing the Adapter

Commissioning the Adapter

To commission the adapter, set the Rack Address Rotary Switches and the Configuration DIP Switches. Either set these switches to the desired settings or disable them by sliding Configuration DIP Switches SW7 and SW8 to the ‘On’ position so that adapter parameters can be used instead.

Important: New switch settings are recognized only when power is applied

to the adapter or it is reset. After you change a switch setting, cycle power or reset the adapter.

ATTENTION: Risk of equipment damage exists. Pen ink or pencil lead may damage the adapter switches. Do not use a pen or pencil to set the switches.

Setting the Rack Address Rotary Switches

The adapter accepts a rack address between 00 and 77 octal. The default setting is 01. See Table 3.A on page 3-3 of the octal address to be used. Set the Rack Address Rotary Switches (Figure 2.1 octal value, but is internally converted to a decimal address. Each Remote I/ O device must have a unique rack address that the controller can recognize. Note the following points:

Configuring and Verifying Key Drive Parameters

The PowerFlex 7-Class 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.

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

1. Use drive Parameter 090 - [Speed Ref A Sel] to set the drive speed

Reference to ‘22’ (DPI Port 5).

2. If hard-wired discrete digital inputs are not used to control the drive,

verify that unused digital input drive Parameters 361 - [Dig In1 Sel] and 362 - [Dig In2 Sel] are set to ‘0’ (Not Used).

3. Verify that drive Parameter 213 - [Speed Ref Source] is reporting that

the source of the Reference to the drive is ‘22’ (DPI Port 5).

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

TIP: For PowerFlex 750-Series drives, use drive Parameter 545 [Speed Ref A Sel] to set the drive speed Reference:

a. Set the Port field to ‘Port 0 - PowerFlex 75x’.

b. Set the Parameter field to point to the port in which the

20-COMM-R adapter/20-750-20COMM Communication Carrier Card are installed (for example, ‘876 - Port 6 Reference’).

The number ‘876’ in the Parameter field of the example is the parameter in the drive that points to the port.

Setting the I/O Configuration

The I/O configuration determines the data that is sent to and from the drive. Logic Command/Status, Reference/Feedback, and Datalinks may be enabled or disabled. (Datalinks allow you to read/write directly to parameters in the drive using Discrete I/O.) A ‘1’ enables the I/O and a ‘0’ disables the I/O.

1. Set the bits in Parameter 12 - [DPI I/O Config].

Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.

2. If Logic Command/Reference is enabled, configure the parameters in

the drive to accept the Logic Command and Reference from the adapter.

For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or 700 drive to ‘22’ (DPI Port 5) so that the drive uses the Reference from the adapter. Also, verify that the mask parameters (for example, Parameter 276 - [Logic Mask]) in the drive are configured to receive the desired logic from the adapter. See the documentation for your drive for details.

20-COMM-R Remote I/O Adapter User Manual

Publication 20COMM-UM004D-EN-P

3. If you enabled one or more Datalinks, configure parameters in the drive

to determine the source and destination of data in the Datalinks.

When using Datalinks, up to 8 drive [Data In xx] parameters (300…307) and/or up to 8 [Data Out xx] parameters (310…317) must be assigned to point to the appropriate drive parameters for your application. Also, ensure that the Remote I/O adapter is the only adapter using the enabled Datalinks. See Chapter 4

About I/O

I/O is used to transfer the data which can control the PowerFlex drive and its speed. It is also used for transmitting data through Datalinks.

The Remote I/O adapter uses Discrete I/O and Block Transfer I/O to transfer I/O data. The ‘Discrete I/O’ is either 1/4 rack (two 16-bit words) or 1/2 rack (four 16-bit words). The rack size is set using Configuration DIP Switch SW4 or, if the hardware switches have been disabled, adapter Parameter 27 - [Rack Size]. The ‘Block Transfer I/O’ includes all Block Transfer Read or Block Transfer Write messages that are 18 words or fewer.

The type of I/O that is transmitted between the drive and controller is set in Parameter 12 - [DPI I/O Cfg]. When you set up your I/O, note the following:

• The Logic Command/Status is always transmitted in the discrete I/O.

• The Reference is transmitted in the Discrete I/O if you are using a 1/2

rack, or in the Block Transfer I/O if you are using a 1/4 rack.

• Datalinks are always transmitted in the Block Transfer I/O.

4-4 Using Discrete and Block Transfer I/O

Discrete I/O Image

The Discrete I/O image is either a 1/4 rack or 1/2 rack. Use Configuration DIP Switch SW4 to select 1/4 rack or 1/2 rack or, if the hardware switches have been disabled, adapter Parameter 27 - [Rack Size]. The I/O that is transmitted depends on the size of the rack. Figure 4.1 image, and Figure 4.2

Data in the Discrete I/O image is transferred between the controller and Remote I/O adapter every scan.

Block Transfer Control/Status Word

Word 0 in the Discrete I/O image is always the 16-bit Block Transfer Control/Status word. The ‘Block Transfer Control’ word is used for handshaking between the scanner and adapter. Do not change this word. The ‘Block Transfer Status’ word is used to determine when you can write and read Block Transfers for Explicit Messages. The section Executing

Block Transfers for Explicit Messages on page 5-5 explains the bits in this

word and how to use them. Block Transfer I/O does not use the Block Transfer Status word.

Logic Command/Logic Status in Discrete I/O Image

shows a 1/4 rack I/O

Word 1 in the Discrete I/O image is always the Logic Command/Logic Status word. The ‘Logic Command’ word is a 16-bit word that is used to control the drive (for example, start, stop, change direction). The ‘Logic Status’ word provides details about how the drive is operating. PowerFlex 750-Series drives have a 32-bit Logic Command/Status word—but when using the 20-COMM-R adapter only the first 16 bits can be used.

PowerFlex 70/700/700H, and PowerFlex 700L Drives with 700 Control

The Reference/Feedback value is a scaled engineering value; it is not in Hertz or RPM. The Reference uses a ‘32767’ scale. The ‘32767’ endpoint of the scale is equal to the value of drive parameter 55 - [Maximum Freq], which has a default value of 130 Hz. For these drives, default scaling is 0…15123 which is equal to 0…60.0 Hz. This is based on the formula shown below. Reference/Feedback scaling is limited by drive parameter 82 - [Maximum Speed]. If the default value of 60 Hz. for parameter 82 - [Maximum Speed] is changed, the speed Reference/Feedback scaling also changes. To determine Reference/Feedback scaling, use the following formula:

(Parameter 82 ÷ Parameter 55) * 32767 = Scaling

Using drive parameter 82 and 55 default values, speed Reference/Feedback scaling is:

(60 Hz ÷ 130 Hz) * 32767 = 15123

Therefore, 0…15123 = 0…60.0 Hz.

If parameter 82 - [Maximum Speed] is changed to 90 Hz, then:

(90 Hz ÷ 130 Hz) * 32767 = 22685

Therefore, 0…22685 = 0…90.0 Hz.

A graphic representation of this Reference/Feedback scaling is shown below.

For PowerFlex 70 drives with enhanced control, firmware 2.xxx or later, or PowerFlex 700 drives with vector control, firmware 3.xxx or later, drive parameter 298 - [DPI Ref Select] was added to simplify scaling for the speed Reference/Feedback. When drive parameter 298 - [DPI Ref Select] is set to its default ‘0’ (Max Freq), the speed Reference/Feedback scaling is as shown above. However, when parameter 298 - [DPI Ref Select] is set to ‘1’ (Max Speed), the speed Reference/Feedback scaling is equal to parameter 82 - [Max Speed]:

Parameter 82 = Scaling

Using the parameter 82 default value, speed Reference/Feedback scaling is:

0…32767 = 0…60.0 Hz.

20-COMM-R Remote I/O Adapter User Manual

Publication 20COMM-UM004D-EN-P

4-6 Using Discrete and Block Transfer I/O

If parameter 82 - [Maximum Speed] is changed to 90 Hz, then:

90 Hz = 32767

Speed Feedback uses the same scaling as the speed Reference.

TIP: For PowerFlex 700 drives with vector control, firmware 3.xxx or later, parameter 299 - [DPI Fdbk Select] enables you to select the feedback data coming from the drive over DPI. The default is ‘Speed Fdbk’ in Hz or RPM determined by Parameter 079 - [Speed Units]. The data selection for parameter 299 is also displayed on the 1st line of the HIM and on DriveExplorer and DriveExecutive software screens in the drive status area of the screen.

PowerFlex 700S and PowerFlex 700L Drives with 700S Control

The Reference/Feedback value is:

32767 = Base Motor Speed

The base speed is set using drive parameter 4 - [Motor RPM]. To set a speed Reference/Feedback above base speed, a value greater than 32767 must be entered.

For 16-bit processors, such as PLC-5 and SLC 500 controllers, the data requires manipulation to set a speed Reference above 32767 or below

-32767. Please see the PowerFlex 700S AC Drives Phase II Control

Reference Manual, publication PFLEX-RM003, in the Chapter 1 ‘Communications’ section. Then go to the ‘PLC 5 or SLC System’ subsection and see the ‘Reference/Feedback Programming’ sub-subsection.

PowerFlex 753/755 Drives

The Reference/Feedback value is Hz x 1000 or RPM x 1000. Drive Parameter 300 - [Speed Units] determines whether the scaling is Hz or RPM. The default scaling is Hz, where 0…60,000 equates to 0…60.000 Hz. When Parameter 300 is set to RPM, then 0…1,765,000 equates to 0…1765.000 RPM.

For 16-bit processors, such as PLC-5 and SLC 500 controllers, the data requires manipulation to set a speed Reference above 32767 or below

Block Transfer I/O requests must be eighteen (18) words or fewer. If a Reference or Datalink In field is not configured to be used by the adapter, any value placed in the field will be ignored by the adapter. If a Datalink Out field is not configured to be used by the adapter, the value of that field is undefined. The Feedback field will always contain the Feedback from the

drive. If a request has fewer than eighteen words, as much I/O data as will fit in the request will be used.

Reference/Feedback in Block Transfer I/O Image

Word 0 and word 1 are reserved for the Reference/Feedback. The size of the Reference (16-bits or 32-bits) is determined by the drive. If a 16-bit Reference (Figure 4.3 as zero (0) during reads.

Important: If the adapter is configured as a 1/2 rack, it uses the Reference

from the Discrete I/O and ignores the Reference in the Block Transfer I/O. Feedback is transmitted in both Discrete I/O and Block Transfer I/O.

Datalinks in Block Transfer I/O Image

Words 2 through 17 are optionally enabled for Datalinks. A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks let a drive parameter value to be read or written without using an Explicit Message. When enabled, each Datalink occupies four 16-bit words in both the input and output Block Transfer I/O image. The size of Datalinks (16 bits or 32 bits) is determined by the drive. If 16-bit Datalinks (Figure 4.3 is not used during writes and is read as zero (0) during reads.

) is used, word 1 is not used during writes and is read

) are used, the most significant word of each Datalink

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 cannot use the same Datalink.

• Parameter settings in the drive determine the data passed through the

Datalink mechanism. Note that some parameters may not be allowed as Datalinks. See the documentation for your drive.

• 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.

Datalink Scaling

PowerFlex 70/700/700H Drives and PowerFlex 700L Drives with 700 Control

Datalink scaling is not automatic and uses whole numbers (INTs or DINTs). See the drive documentation to determine the unit resolution for the associated parameter Datalink. For example, PowerFlex 700VC drive parameter 3 - [Output Current] has a 0.1 unit resolution. Because Datalink scaling uses whole numbers, the Output Current value is multiplied by 10 in the adapter and then sent over the network. Suppose the actual Output Current value is 35.5 amps. Reading the associated parameter Datalink received by the controller, the value would be 355. By using ladder logic, divide the value by 10 in the controller to get the correct scaling. See the drive documentation to determine if the Datalink parameter is a 16-bit or 32-bit parameter.

PowerFlex 700S, PowerFlex 700L with 700S Control, PowerFlex 753/755, and PowerFlex Digital DC Drives

Datalinks require scaling in the following way. Parameters are either 16-bit or 32-bit integers or REALs. When the parameter is a 32-bit integer, the data needs to be copied using a COP command to a DINT tag. (Because PLC-5 and SLC 500 controllers do not support 32-bit integers, the data must be separated into two 16-bit integers.) When the parameter is a REAL, the data needs to be copied using a COP command to a REAL tag. See subsequent sections in this chapter for ladder logic examples. See the drive documentation to determine if the Datalink parameter is a 16-bit or 32-bit integer parameter, or a REAL parameter.

Using 16-Bit Datalinks to Read/Write 32-Bit Parameters

This subsection only pertains to PowerFlex 70 (standard or enhanced control), PowerFlex 700 (standard control), and PowerFlex 700H drives which use 16-bit Datalinks. To read 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 10 - [Elapsed Run Time] in a PowerFlex 70 drive, both Datalink A1 Out (Parameter 310) and Datalink A2 Out (Parameter 311) are set to ‘10’. Datalink A1 Out will contain the least significant word (LSW) and Datalink A2 Out will contain the most significant word (MSW).

32-bit data is stored in binary as follows:

MSW 231 through 2

LSW 215 through 2

20-COMM-R Remote I/O Adapter User Manual

Publication 20COMM-UM004D-EN-P

4-10 Using Discrete and Block Transfer I/O

In this example, the Parameter 10 - [Elapsed Run Time] value of 6553.9 Hrs is read as ‘6553.9’ in Datalink A1 Out (Parameter 310) and Datalink A2 Out (Parameter 311).

Datalink Word Parameter Data (Hex)

A1 Out LSW 10 0003

A2 Out MSW 10 0001

Conversion Example:

Parameter 010 - [Elapsed Run Time] = 6553.9 Hrs MSW = 0001 LSW = 0003 Engineering Value = 65536 + 3 = 65539 Parameter 10 Displayed Value = 6553.9 Hrs

Regardless of the Datalink combination, Datalink x1 Out will always contain the LSW and Datalink x2 Out will always contain the MSW. In the following example, the PowerFlex 70 drive parameter 242 - [Power Up Marker] contains a value of 88.4541 hours.

SLC 500 Controller Examples

Examples in this section are provided for SLC 500 Series C controllers with firmware revision 3.xx and higher, and for SLC 500 controllers all versions.

Series C Controller with Firmware Revision 3.xx and Higher

In a series C, firmware revision 3.xx and higher SLC processor, Block Transfer Read (BTR) and Block Transfer Write (BTW) instructions can be used. When the length of the Block Transfer is 18 words or less, the 20-COMM-R adapter knows the Block Transfer is for I/O and not for an explicit message Block Transfer (Chapter 5). Block Transfer setup is the same for a 1/4 rack or 1/2 rack configuration. This example is for Rack 1, Group 4 (the upper half rack).

Block Transfer Read Example

The following data is used for this example.

• Rack 1

• Group 4 (upper half rack)

• Slot 0 (always 0)

• Control Block N9:0 (user defined)

• Data File N21:0 (user defined)

• Buffer File M1:x.100 (Block Transfer Reads always start with M1,

where x is the slot in which the 1747-SN scanner card is in. In this example, the 1747-SN card is in slot 2.)

• Requested Word Count is 18 or less (see See Figure 4.1 on page 4-2

See Figure 4.2 on page 4-3

• Transmitter Word Count (always 0)

• Control Block Length (always 3)

)

Important: Each Block Transfer needs to be offset by 100 (M1:x.100) and

the default is 3300 words, so you can perform up to 33 Block Transfers. See the advanced configuration for your 1747-SN scanner card under channel configuration.

All Controller Versions

The SLC RIO scanner performs Block Transfers through control/status buffers that you allocate in the scanner’s M0 and M1 files. The first 10 words of each file are reserved for either control words (M0) or status words (M1). Block Transfer Read/Write data starts in word 11. See the Remote I/O 1747-SN Scanner User Manual, publication 1747-UM013, for more information.

The following data is required for the example program.

ATTENTION: Risk of equipment damage exists. If Block Transfer is used to send Explicit Messages that are programmed to write parameter data to Nonvolatile Storage (NVS) frequently, the NVS will quickly exceed its life cycle and cause the drive to malfunction. Do not create a program that frequently uses Block Transfer to send Explicit Messages to write parameter data to NVS. Datalinks do not write to NVS and should be used for frequently changed parameters.

About Block Transfer Messaging

Formatting Block Transfer Messages

Block Transfer messaging is used to transfer data to the drive. The size of Block Transfer messages to the Remote I/O adapter determines their purpose.

Block Transfer I/O

For information about Block Transfer I/O messages, see Chapter 4, Using

Discrete and Block Transfer I/O.

One Block Transfer request is processed per Remote I/O rack scan, but multiple requests to a rack can be initiated. You can use Block Transfer Read messages to gather input and status data from the adapter and Block Transfer Write messages to send output and configuration data to the adapter and connected drive.

Block Transfer Write Structure to Send Block Transfer Messages

Data Field Description

Word 0 Length

The least significant byte contains the length of the Explicit Message. The most significant byte is always zero. This is the length of the actual message in bytes, not the size of the BTW in words.

This length excludes the two bytes of word 0, but includes words 1 and 2, and all of the data in the main body of the message to be sent. If using a scattered read or write with class code 0x93, the length includes the zero(s) after the last parameter as place holders. See pages C-9…C-14.

Word 1 0x81 and DPI Port

The least significant byte contains the value 0x81. The most significant byte is the DPI port. For PowerFlex drives, you can access:

0 - Drive 1 - Device at Port 1 (HIM) 2 - Device at Port 2 3 - Device at Port 3

Word 2 CIP Service

The least significant byte contains a CIP service. The most significant byte is always zero (0). CIP services include the following:

0x0E - Get Attribute Single 0x10 - Set Attribute Single

Word 3 CIP Class

See Appendix C

Word 4 CIP Instance

Executing Block Transfers for Explicit Messages

1. Enter data into the program.

Data must be entered into a data file for a program to run. The data file that is used depends on your controller and application.

2. Run the program.

When executing a Block Transfer message, the program must monitor the Block Transfer Status word (Word 0) in the Discrete I/O Image. Its bits are defined as shown in the following table.

Bits Name and Description

0…7 Node Adapter Chip

These bits are used by the node adapter chip to communicate with the master on the network. The master application should not use these bits.

8 DATA_VALID

0 = Data from the drive is not valid. 1 = Data from the drive is valid.

9 Message Block Transfer Write Available

0 = Not ready 1 = Ready to receive a Block Transfer write.

10 Message Block Transfer Read Available

0 = Not ready 1 = Data is available for a Block Transfer read.

Before initiating a Block Transfer Write message, bit 9 must be 1. This setting indicates that a Block Transfer Write can be executed.

Because only one Block Transfer message can be active at a time, bit 9 is set to 0 when the Block Transfer Write begins. Bit 9 and bit 10 remain at zero while the Block Transfer is being processed.

This setting indicates that the program can perform either a Block Transfer Read or a Block Transfer Write.

Bit 11 remains at 0 if messaging is successful. If an error occurs, it would be set to 1.

Example Programs

3. Receive data from the program.

After the program with Block Transfer messages has been run, the results can be seen in a data file. The data file that is used depends on your controller and application.

The example ladder logic programs (Figure 5.3, Figure 5.4, and Figure 5.6) can be used to demonstrate how Block Transfer can be used to send Explicit Messages from a ControlLogix, PLC or SLC controller, respectively. With these examples, Block Transfer messaging is used to read or write a parameter value from a PowerFlex 70 drive at Rack 1, Group 0, Slot 0.

These example ladder programs are continuations of the Discrete and Block Transfer I/O example ladder programs in Chapter ladder logic in that chapter performs Jump to Subroutines (JSRs) to these examples.

Viewing and Clearing Events

The adapter has an event queue to record significant events that occur in the operation of the adapter. When such an event occurs, an entry is put into the event queue. You can view the event queue with any of these drive configuration tools:

• LCD PowerFlex 7-Class HIM

• Connected Components Workbench software, version 1.02 or later

• DriveExplorer software, version 2.01 or later

• DriveExecutive software, version 1.01 or later

The event queue can contain up to 32 entries. Eventually the event queue will become full, since its contents are retained through adapter resets. At that point, a new entry replaces the oldest entry. Only an event queue clear operation or adapter power cycle will clear the event queue contents.

Resetting the adapter to defaults has no effect on the event queue.
