Step 4. For 1-20 HP SP600 drives, fold the Internal Interface cable behind the module and mount the module on the drive using the four captive screws. See figure 3.6. For frame 2 and larger SP600 drives, mount the module on the drive using the four captive screws to secure and ground it to the drive. Important: All screws must be tightened since the module is grounded through a screw. The recommended tightening torque is 0.9 N-m (8 in-lb).
3.6 Applying Power ! ATTENTION: Unpredictable operation may occur if parameter settings and switch settings are not compatible with your application. Verify that settings are compatible with your application before applying power to the drive. Failure to observe these precautions could result in severe bodily injury or loss of life. Step 1. Verify that the module will have a unique address on the network. If a new address is needed, reset its switches (refer to section 3.2, Commissioning the Module).

CHAPTER 4 Configuring the PROFIBUS Module Chapter 4 provides instructions and information for setting the parameters in the module. For a complete list of parameters, refer to Appendix B, PROFIBUS Module Parameters. For definitions of terms in this chapter, refer to the Glossary. 4.1 Configuration Tools The PROFIBUS module stores parameters and other information in its own non-volatile memory. Therefore, you must access the module to view and edit its parameters. Table 4.
4.2 Using the LCD OIM to Configure the Module Use the procedure in figure 4.1 to access the parameters on the PROFIBUS module using the LCD OIM. If you are unfamiliar with the operation of the LCD OIM, refer to the SP600 AC Drive User Manual (D2-3485 or D2-3501) for more information.
4.4 Setting the I/O Configuration The I/O configuration determines the type of data sent to the drive. Logic Command/Status, Reference/Feedback, and Datalinks may be enabled or disabled. Step 1. Set the bits in module parameter 11 (DPI I/O Config) as shown in figure 4.3. A “1” enables the I/O. A “0” disables it. Bit 0 is the right-most bit. In figure 4.3, it is highlighted and equals “1.
4.5 Setting a Fault Action ATTENTION: Parameter 9 (Comm Flt Action) and parameter 10 (Idle Flt Action) let you determine the action of the module 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. Precautions should be taken to ensure that the settings of these parameters do not create a risk of injury or equipment damage.
4.5.1 Setting the Fault Configuration Parameters If you set module parameter 9 (Comm Flt Action) or module parameter 10 (Idle Flt Action) to “Send Flt Cfg,” the values in the parameters shown in table 4.3 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. Table 4.
4.5.2 Resetting the Module Changes to switch settings or some module parameters require that you reset the module before the new settings take effect. You can reset the module by cycling power to the drive or by using module parameter 8 (Reset Module). ! ATTENTION: If the module is transmitting control I/O to the drive, the drive may fault when you reset the module. Determine how your drive will respond before resetting a connected module.
4.6 Viewing the Module Configuration The parameters in table 4.4 provide information about how the module is configured. You can view these parameters at any time. Table 4.4 – Module Configuration Status Parameters Number Name Description 01 DPI Port The port on the drive to which the module is connected. Usually, it is port 5. 02 DPI Data Rate The data rate used by DPI in the drive. It is set in the drive, and the module detects it. 04 P-DP Addr The node address used by the module.

CHAPTER 5 Configuring the PROFIBUS 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 a module connected to a network. PROFIBUS scanners are available from several manufacturers, including SST. SST PROFIBUS scanners come with a software tool for configuring the scanner (see figure 5.1). Device Library window Network Configuration window [001]_RECOMM_PBUS [002]_RECOMM_PBUS Online Browse window Figure 5.
5.1 Configuring a Simple Network: An Example In this example, we will be configuring two SP600 drives to be Station 1 and Station 2 on a PROFIBUS network. This will be the configuration used throughout the manual, including the ladder examples. Apart from the node address and scanner mapping, they will have identical configurations. This chapter describes the steps to configure a simple network like the network in figure 5.2.
Follow the steps outlined below only when a new GSD file needs to be added to the SST PROFIBUS Configuration Software Tool. Typically, this is only done once, after the software tool is initially installed or if configuring a RECOMM-PBUS on the network for the very first time with this software tool. The software tool comes with standard data files as shown in figure 5.3. Additional data files, such as the RECOMM-PBUS GSD file, will need to be added to configure the RECOMM-PBUS in the scanner. Figure 5.
Step 3. Find the directory location of the data file(s) you wish to add (typically, the source location is a floppy disk in drive A:). “Rele0573.gsd” is the GSD file for the RECOMM-PBUS as shown in figure 5.5. Rele0573.gsd Rele0573.gsd Figure 5.5 – Adding the GSD File for the RECOMM-PBUS Step 4. Select “Rele0573.gsd” for the RECOMM-PBUS and click Open. Step 5. Click on the (+) sign of the Slaves folder as shown in figure 5.6. Reliance Electric RECOMM-PBUS [V1.001.01] Figure 5.
5.2 Configuring the SST-PFB-SLC PROFIBUS Scanner The following steps are performed to configure the SST-PFB-SLC scanner using the SST PROFIBUS Configuration Software Tool. In our example, the PROFIBUS network will consist of a SLC master and two SP600 drives.
Step 4. A user-defined Name and Description can be given to the scanner. In our example, the scanner will be Station 0 on the network, as shown in figure 5.7. Figure 5.7 – SST-SST-PFB-SLC Master (General) Dialog Box Step 5. Click on the Parameters tab to view the Scan Cycle Times. In our example, use the default settings as shown in figure 5.8. Figure 5.
Step 7. Accept the settings in our example (COM1 on the PC at 115200 bps baud rate), as shown in figure 5.9. Figure 5.9 – COM Port Default Settings Step 8. The scanner will appear in the network window as shown in figure 5.10. Double-click on the scanner in the network window. Figure 5.10 – Scanner Network Window Step 9. Double-click on the RECOMM-PBUS listed in the Reliance Electric library folder. A user-defined Name and Description can be given to this RECOMM-PBUS.

CHAPTER 6 Using I/O Messaging Chapter 6 provides information and examples that explain how to use I/O Messaging to control an SP600 drive. ! 6.1 ATTENTION: 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.
The I/O image table will vary based on the following: • Size (either 16-bit or 32-bit) of the Reference/Feedback word and Datalink words used by the drive. • Configuration of parameter 11 (DPI I/O Config). If not all I/O is enabled, the image table is truncated. The image table always uses consecutive words starting at word 0. Figure 6.1 illustrates an example of an I/O image with 16-bit words.
An image that uses 32-bit words for Reference and Datalinks would change the I/O image in figure 6.1 as follows: Word I/O Word I/O 0 Logic Command/Status 7 - 10 Datalink B 1-2 Reference/ Feedback 11 - 14 Datalink C 3-6 Datalink A 15 - 18 Datalink D Figure 6.2 illustrates an example of an I/O image that does not use all of the I/O data. Only the Logic Command/Reference and Datalink B are enabled. In this example, the Reference is a 32-bit word, and Datalinks are 16-bit words.
6.3 Using Logic Command/Status When enabled, the Logic Command/Status word is always word 0 in the I/O image. The Logic Command is a 16-bit word of control produced by the scanner and consumed by the module. The Logic Status is a 16-bit word of status produced by the module and consumed by the scanner. This manual contains the bit definitions for compatible products available at the time of publication in Appendix C, Logic Command/ Status Words. For other products, refer to their documentation. 6.
• 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. 6.5.2 32-Bit Parameters using 16-Bit Datalinks To read (and/or write) a 32-bit parameter using 16-bit Datalinks, typically both Datalinks (A,B,C,D) are set to the 32-bit parameter.
Example: Power Up Marker (242) = 88.4541 hours MSW = 13decimal = 1101binary = 219 + 218 + 216 = 851968 LSW = 32573 851968 + 32573 = 884541 6.6 Sample SLC Ladder Logic Program The PROFIBUS sample program uses an SLC processor with an SST PROFIBUS scanner (SST-PFB-SLC) in the first slot of the rack and will work with SP600 drives.
Parameter Settings Table 6.
SLC Data Table Read Data File N10: contains the actual read data that can be used elsewhere in the ladder program.
Logic Command/Status Words The examples in sections 6.7 and 6.8 use the Logic Command word and Logic Status word for SP600 drives. Refer to Appendix C, Logic Command/Status Words, for more information. The definition of the bits in these words may vary if you are using a different DPI Host product. Refer to the documentation for your Host product.
6.7 Sample SLC Ladder Logic - Main Program This sample program is for a PROFIBUS demonstration using a SLC 5/05 processor with an SST Profibus scanner (SST-PFB-SLC) in the first slot of the rack.
PROFIBUS scanners vary from manufacturer to manufacturer in how the bytes are ordered in a word. For example, some PROFIBUS scanners operate with high & low bytes swapped (the value "1234" is represented as "3412"). The READ data is copied into N10: and the bytes are reversed in the SWP instruction below so a value such as "3412" is viewed as "1234".

CHAPTER 7 Using Explicit Messaging (Parameter Protocol) Chapter 7 provides information and examples that explain how to use Explicit Messaging to monitor and configure the module and connected SP600 drive, as well as other peripherals. ! ATTENTION: The examples in this publication are intended solely for purposes of example. There are many variables and requirements with any application.
Refer to step 21 in chapter 5 to view the procedure for adding the “Parameter Access” module to a configuration. This maps four words input and output to the end of the I/O configuration, which is used as the request/response in the parameter message format (figure 7.2). Parameter 23 (Parameter Mode) in the PROFIBUS module is used to configure the parameter protocol that is active. The default protocol is the Parameter Protocol. 7.
7.3 Parameter Protocol This protocol uses four words in the PROFIBUS I/O area. Requests and responses are a handshake procedure and cannot be batched, meaning that if the master sends a request, it has to wait for the response before sending a new request.
7.3.1 Parameter Message Request Table 7.1 – Parameter Message Request Data Word 1 Description PNU - Parameter Number (Bit 0-10) The parameter number determines which parameter to access in the selected peripheral.

C-4 PROFIBUS Communications Module
GLOSSARY communications module - Devices such as drives, controllers, and computers usually require a module to provide a communication interface between them and a network such as PROFIBUS. A module 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 RECOMM-PBUS PROFIBUS module is an module that connects SP600 drives to a PROFIBUS network.
DPI - A peripheral communication interface used by various Reliance Electric drives and power products. DPI peripheral - A device that provides an interface between DPI and a network or user. Peripheral devices are also referred to as “modules” and “modules.” The serial converter and SP600 OIM 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 SP600 drive is a DPI product.
Logic Command/Logic Status - The Logic Command is used to control the SP600 drive (e.g., start, stop, direction). It consists of one 16-bit word of input to the module from the network. The definitions of the bits in this word depend on the drive. The Logic Status is used to monitor the SP600 drive (for example, operating state, motor direction). It consists of one 16-bit word of output from the module to the network. The definitions of the bits in this word depend on the drive.
scanner - A separate module (of a multi-module controller) or a built-in component (of a single-module controller) that provides communication with modules connected to a network. Also called a master. See also controller. status indicators - LEDs that are used to report the status of the module, network, and drive. They are on the module and can be viewed on the front cover of the drive when the drive is powered.
