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.
Chapter 3 Configuring the Adapter This chapter provides instructions and information for setting the parameters to configure the adapter.
3-2 Configuring the Adapter Using the PowerFlex 7-Class If your drive has either an LED or LCD HIM (Human Interface Module), it can be used to access parameters in the adapter as shown below. It is HIM recommended that you read through the steps for your HIM before performing the sequence. For additional information, refer to your PowerFlex Drive User Manual or the PowerFlex 7-Class HIM Quick Reference (publication 20HIM-QR001). Using an LED HIM Step 1.
Configuring the Adapter Using BOOTP 3-3 By default, the adapter is configured so that you can set its IP address, subnet mask, and gateway address by using a BOOTP utility. You can select from a variety of BOOTP utilities. These instructions use Rockwell’s BOOTP Server (version 2.3 or higher), a stand-alone program that incorporates the functionality of standard BOOTP utilities with a graphical interface. It is available from http://www.software.rockwell.com/support/ download/detail.cfm?ID=3390.

Configuring the Adapter 3-5 8. Click OK to apply the settings. The adapter appears in the Relation List (Figure 3.4) with the new settings. Figure 3.4 BOOTP Server Window with Adapter in the Relation List 9. To assign this configuration to the adapter permanently, select the device in the Relation List and click Disable BOOTP/DHCP. When power is cycled on the adapter, it will use the configuration you assigned it and not issue new BOOTP requests.
3-6 Configuring the Adapter Setting the IP Address, Subnet Mask, and Gateway Address By default, the adapter is configured so that you set its IP address, subnet mask, and gateway address using a BOOTP server. If you want to set these attributes using the adapter parameters instead, you must disable BOOTP and then set the appropriate parameters in the adapter. Disabling the BOOTP Feature 1. Set the value of Parameter 03 - [BOOTP] to “0” (Disabled). Figure 3.
Configuring the Adapter 3-7 Setting a Subnet Mask Using Parameters 1. Verify that Parameter 03 - [BOOTP] is set to “0” (Disabled). This parameter must be set to Disabled to configure the subnet mask using the adapter parameters. 2. Set the value of Parameters 08 - [Subnet Cfg 1] through 11 - [Subnet Cfg 4] to the desired value for the subnet mask. Figure 3.7 Example Subnet Cfg 1 LCD HIM Screen Default = 0.0.0.0 Port 5 Device 20-COMM-M Parameter #: 08 Subnet Cfg 1 0 0 <> 255 255 . 255 . 255 .
3-8 Configuring the Adapter Setting the Data Rate By default, the adapter is set to autodetect, so it automatically detects the data rate and duplex setting used on the network. If you need to set a specific data rate and duplex setting, the value of Parameter 16 - [EN Rate Cfg] determines the Ethernet data rate and duplex setting that the adapter will use to communicate. For definitions of data rate and duplex, refer to the Glossary. 1.
Configuring the Adapter 3-9 3. If you enabled one or more Datalinks, configure parameters in the drive to determine the source and destination of data in the Datalink(s). For example, configure the Datalinks in PowerFlex 70 and 700 drives by setting Parameters 300 - [Data In A1] through 317 - [Data Out D2]. Also, ensure that the Modbus/TCP adapter is the only adapter using the enabled Datalink(s). 4. Reset the adapter (see Resetting the Adapter on page 3-12). The adapter is ready to receive I/O.
3-10 Configuring the Adapter Setting the Fault Configuration Parameters If you set Parameter 23 - [Comm Flt Action] to “Send Flt Cfg,” the values in the following parameters are sent to the drive after an I/O communications fault and/or idle fault occurs. You must set these parameters to values required by your application. Parameter 26 - [Flt Cfg Logic] 27 - [Flt Cfg Ref] 28 - [Flt Cfg x1 In] through 35 - [Flt Cfg x2 In] Description A 16-bit value sent to the drive for Logic Command.
Configuring the Adapter 3-11 Setting Web Access Control By using a web browser to access the IP address set for the adapter, you can view the adapter’s web pages for information about the adapter, its connected drive, and other DPI devices connected to the drive, such as HIMs or converters.
3-12 Configuring the Adapter 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 power cycling the drive or by using Parameter 22 - [Reset Module]. ! 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.
Configuring the Adapter Flash Updating the Adapter 3-13 The adapter can be flash updated over the network or serially through a direct connection from a computer to the drive using a 1203-USB or 1203-SSS serial converter. When flashing over the network, you can use the Allen-Bradley software tool ControlFLASH, the built-in flash capability of DriveExplorer Lite or Full, or the built-in flash capability of DriveExecutive.

Chapter 4 Using Modbus/TCP Function Codes This chapter provides information about controlling a PowerFlex 7-Class drive, setting its Reference, and accessing its parameters and the parameters of its connected peripherals using Modbus/TCP Function Codes over the Modbus/TCP network.
4-2 Using Modbus/TCP Function Codes Supported Modbus/TCP Function Codes On Modbus/TCP, a register is defined as an addressable container that holds 16-bit data. All parameters (16-bit or 32-bit) for the drive and its connected peripherals always occupy two consecutive 16-bit registers—one for the Lo Word and one for the Hi Word—even if the parameter is only a 16-bit word. In this case, the parameter value is the Lo Word. The adapter supports the Modbus/TCP function codes listed in Table 4.A. Table 4.
Using Modbus/TCP Function Codes Unit Identifier 4 5 6 7…15 16 17…254 255 4-3 Device Connection (Example) DPI Port 4 (peripheral connected to Port 4 of a four-way splitter cable) DPI Port 5 (peripheral connected to the drive’s internal Port 5 or to Port 5 of a four-way splitter cable) DPI Port 6 (reserved for future use) Reserved for future use DPI Port 0 (Drive) — an alternate to using Unit Identifier 0 Unused — defaults to Unit Identifier 0 Adapter Using Function Code 43 to Read Drive Identification Fu
4-4 Using Modbus/TCP Function Codes Peripheral Status Register (Address 10022) The Peripheral Status register contains information on which DPI Ports presently have a peripheral connected and logged into the drive according to Table 4.C. By using Function Code 03 or 23, you can read register address 10022 to conveniently determine which DPI Ports and peripherals are in use. Table 4.

The Reference value is a scaled engineering value; it is NOT in Hertz or RPM. The Reference uses a “32767” scale.
Using Modbus/TCP Function Codes 4-7 Speed Feedback uses the same scaling as the speed Reference. TIP: For PowerFlex 700 VC drives (firmware v3.xxx or higher), 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].

Using Modbus/TCP Function Codes Accessing Device Parameters 4-9 There are two methods for accessing parameters in the drive or its connected peripherals: the direct access method (for individual or contiguous parameters) and the indirect access method (for contiguous or non-contiguous parameters). Direct Access Method ! ATTENTION: Risk of equipment damage exists.
4-10 Using Modbus/TCP Function Codes Indirect Access Method ! ATTENTION: Risk of equipment damage exists. When adapter Parameters 38 - [Indirect Par #1] through 53 - [Indirect Par #16] and their corresponding data registers are used to write parameter data to Non-Volatile 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 Indirect Parameters to write parameter data to NVS.
Using Modbus/TCP Function Codes 4-11 Reading Device Parameters 1. Verify that the Unit Identifier is set to “0” (zero) or “16.” 2. Using Table 4.J and its associated formula, determine the value to use for an adapter Indirect Par #x that points to the specific device parameter you want to read. For example, suppose adapter Parameter 38 - [Indirect Par #1] is used and you want to read drive Parameter 003 - [Output Current] or drive Parameter 012 - [DC Bus Voltage].
4-12 Using Modbus/TCP Function Codes Writing Device Parameters 1. Verify that the Unit Identifier is set to “0” (zero). 2. Using Table 4.J and its associated formula, determine the value to use for an adapter Indirect Parameter that points to the specific device parameter you want to write. For example, suppose adapter Parameter 38 - [Indirect Par #1] is used and you want to write to drive Parameter 140 - [Accel Time 1]. In this case, set adapter Parameter 38 - [Indirect Par #1] to a value of “140.” 3.
Using Modbus/TCP Function Codes 4-13 Table 4.
4-14 Using Modbus/TCP Function Codes Using 16-Bit Datalinks to Read/Write 32-Bit Parameters This subsection only pertains to PowerFlex 70 (SC or EC), PowerFlex 700 (SC), 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 and Datalink A2 Out are set to “10.
Using Modbus/TCP Function Codes Supported Modbus Registers 4-15 The adapter supports the Modbus registers listed in Table 4.N. Table 4.

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 Modbus/TCP. 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 20-COMM-M Modbus/TCP adapter connects PowerFlex 7-Class drives to a Modbus/TCP network.
G-2 Glossary Datalinks A Datalink is a type of pointer used by PowerFlex 7-Class drives to transfer data to and from the controller. Datalinks allow specified parameters to be read or written to without using explicit messages. When enabled, each Datalink in a PowerFlex 7-Class drive 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.
Glossary G-3 E EDS (Electronic Data Sheet) Files 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 and revision. EDS files for many Allen-Bradley products can be found at http://www.ab.com/networks/eds. 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.
G-4 Glossary Hold Last When communication is 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.
Glossary L G-5 Logic Command/Logic Status The Logic Command is used to control the PowerFlex 7-Class 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, and are shown in Appendix C. The Logic Status is used to monitor the PowerFlex 7-Class drive (for example, operating state, motor direction). It consists of one 16-bit word of input from the adapter to the network.
G-6 Glossary R Reference/Feedback The Reference is used to send a setpoint (for example, speed, frequency, torque) to the drive. It consists of one word of output 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 input 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.
