1-8 Notes: Getting Started
Chapter 2 Installing the Adapter This chapter provides instructions for installing the adapter in a PowerFlex 40, PowerFlex 40P or PowerFlex 400 drive. This adapter can also be installed in a DSI External Comms Kit. In this case, refer to the 22-XCOMM-DC-BASE Installation Instructions (publication 22COMM-IN001) supplied with the kit.
2-2 Installing the Adapter 1. Set the adapter Node Address / Firmware Update switches (see Figure 2.1). The Profibus Node Address/Firmware Update State is configurable using an 8-bit DIP switch. The low seven bits set a node address and the valid address allows binary coding of 1 through 125. A new node address setting is recognized only when power is applied to the adapter by power cycling the drive or after an adapter Reset Module command.
Installing the Adapter Figure 2.2 Node Address Switch Settings (UP = OPEN = 1 = Off) Node Addr.
2-4 Installing the Adapter 2. Verify the Network Baud rate, which is set by the network master and depends on cable length (see Glossary). The 22-COMM-P adapter uses the Auto-Baud function, which enables the adapter to recognize the present baud rate and automatically sets itself to the transmission rate used by the master. The adapter supports the following data rates: 9.6 Kbps, 19.2 Kbps, 45.45 Kbps, 93.75 Kbps, 187.5 Kbps, 500 Kbps, 1.5 Mbps, 3 Mbps, 6 Mbps, and 12 Mbps.

Chapter 3 Configuring the Adapter This chapter provides instructions and information for setting the parameters in the adapter.
3-2 Configuring the Adapter Using the Optional, External PowerFlex 4-Class HIM Adapter parameters cannot be accessed using the integral keypad on a PowerFlex 4-Class drive. You must use Drive Explorer or DriveExecutive software, or an optional, external PowerFlex 4-Class HIM (22-HIM-A3 or 22-HIM-C2S). Basic steps to access parameters in the adapter are shown in Table 3.A. For additional HIM information, refer to the PowerFlex 4-Class HIM Quick Reference (publication 22HIM-QR001).
Configuring the Adapter 3-3 Table 3.A Accessing Adapter Parameters Using the HIM (Continued) Step Example Screens 5. Press (Enter) key to access the Mode parameters. Edit the adapter Parameter: parameters using the same techniques that you use to edit drive parameters. Single Drv VALUE RO # 001 0 LIMITS SEL NOTE: All configuration procedures throughout this chapter use the optional, external PowerFlex 4-Class HIM to access parameters in the adapter and show HIM screens.
3-4 Configuring the Adapter Setting the Node Address See page 2-2 for details to set the node address. Setting the I/O Configuration The I/O configuration determines the number of drives that will be represented on the network as one node by the adapter. If the Mode Jumper J2 is set to the “1x” (Single mode) default position, only one drive is represented by the adapter and Parameter 11 - [DSI I/O Cfg] has no effect.
Configuring the Adapter 3-5 Setting a Fault Action By default, when Profibus communication is disrupted (for example, a cable is disconnected) or the master is idle, the drive responds by faulting if it is using I/O from the network. You can configure a different response to communication disruption using Parameter 9 - [Comm Flt Action] and a different response to an idle scanner using Parameter 10 [Idle Flt Action]. ! ATTENTION: Risk of injury or equipment damage exists.
3-6 Configuring the Adapter Changes to these parameters take effect immediately. A reset is not required. If Multi-Drive mode is used, the same fault action is used by the adapter for all of the drives it controls (Drive 0, Drive 0-1 to Drive 0-4). Setting the Fault Configuration Parameters If you set Parameter 9 - [Comm Flt Action] or 10 - [Idle Flt Action] to the “Send Flt Cfg,” the values in the following parameters are sent to the drive after a communications fault occurs and/or the scanner is idle.
Configuring the Adapter ! 3-7 ATTENTION: Risk of injury or equipment damage exists. Parameter 25- [DSI Loss Action] lets you determine the action of the adapter when DSI communication with the drive has been lost. By default, this parameter maintains the Logic Status and Feedback word values sent to the controller at the time DSI communication between the adapter and drive was lost (that is, hold last state).
3-8 Configuring the Adapter Resetting the Adapter Changes to switch settings or 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.
Configuring the Adapter 3-9 Viewing the Adapter Configuration The following parameters provide information about how the adapter is configured. You can view these parameters at any time. Adapter Parameter Description 01 - [Mode] Displays the adapter operating mode selected with the Mode Jumper J2. Values 0 = Single Drv operation 1 = Multiple Drv operation 04 - [P-DP Addr Actual] Profibus Node Address actually used by the adapter. 05 - [P-DP Rate Actual] Profibus actual operating data rate.

Chapter 5 Using I/O Messaging This chapter provides information that explains how to use I/O Messaging to control a PowerFlex 40 drive. ! Topic Page About I/O Messaging 5-1 Understanding the I/O Image 5-2 Using Logic Command/Status 5-3 Using Reference/Feedback 5-3 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.
5-2 Using I/O Messaging Understanding the I/O Image The Profibus specification requires that the terms input and output be defined from the scanner’s point of view. Therefore, Output I/O is data that is output from the scanner and consumed by the Profibus 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: • Configuration of the Mode Jumper (J2) on the adapter and Parameter 11 - [DSI I/O Cfg].
Using I/O Messaging 5-3 Using Logic Command/Status The Logic Command is a 16-bit word of control produced by the controller and consumed by the adapter. The Logic Status is a 16-bit word of status produced by the adapter and consumed by the controller. When enabled, the Logic Command/Status word is always word 0 in the I/O image. This manual contains the bit definitions for compatible products available at the time of publication in Chapter C, PowerFlex 4-Class Drives Logic Command/Status Words.

Chapter 6 Using the Parameter Messaging This chapter provides information that explains how to use Parameter Messaging to monitor and configure the adapter and connected PowerFlex 4-Class drive, as well as other peripherals. ! ! Topic Page About the Parameter Messaging 6-1 Running the Parameter Messaging 6-2 Parameter Protocol 6-3 ATTENTION: Risk of injury or equipment damage exists. The examples in this publication are intended solely for purposes of example.
6-2 Using the Parameter Messaging Running the Parameter Messaging There are five basic events in the Parameter Data Exchange process defined below. 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 an response message for all Parameter Data, whether you are reading or writing a data. Figure 6.
Using the Parameter Messaging 6-3 Parameter Protocol This protocol uses 4 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. With this protocol you can: • • • • • Read 8-bit or 16-bit parameters from any DSI port Write 8-bit or 16-bit parameters to any DSI port Read the Adapter Fault Code Read Events Read Diagnostic Items Figure 6.
6-4 Using the Parameter Messaging Parameter Message Request Word Description 1 PNU - Parameter Number (Bit 0-10) The parameter number determines which parameter to access, in the selected peripheral. Parameters 1 - 1023 can be accessed. Parameter numbers 1024 - 2047 are used to access the fault object. Parameter 1024 is equal to the latest fault, 1025 to the prior fault, and so on.
Using the Parameter Messaging 6-5 Parameter Message Response Word Description 1 PNU - Parameter Number (Bit 0-10) Requested parameter number. SPM - Spontaneous Message (Bit 11) Reserved - is always set to 0.

Chapter 7 Using Multi-Drive Mode This chapter provides information to explain how to use Multi-Drive mode. ! Topic Page Single Mode versus Multi-Drive Mode 7-1 Additional Information 7-5 System Wiring 7-5 Understanding the I/O Image 7-7 Configuring the RS-485 (DSI) Network 7-8 Multi-Drive Mode Parameter Data 7-10 ATTENTION: Hazard of injury or equipment damage exists. The examples in this publication are intended solely for purposes of example.
7-2 Using Multi-Drive Mode Figure 7.1 Single Mode Example - With Adapter in Drive 1 drive per node Profibus PowerFlex 40/40P/400 Drive with 22-COMM-P PowerFlex 40/40P/400 Drive with 22-COMM-P PowerFlex 40/40P/400 Drive with 22-COMM-P When the adapter cannot be installed in the drive (for example, a PowerFlex 4 or PowerFlex 4M drive) but operated in Single mode, the adapter can be installed in a DSI External Comms Kit (Figure 7.2). Figure 7.
Using Multi-Drive Mode 7-3 Multi-Drive mode is an alternative to the typical network installation, where a single Profibus node can consist of one to five drives. In Figure 7.4, the 22-COMM-P adapter is internally mounted in a PowerFlex 40, PowerFlex 40P or PowerFlex 400 drive, and the remaining PowerFlex 4-Class drives are daisy-chained from the RS-485 port on the first drive. Figure 7.
7-4 Using Multi-Drive Mode Benefits of Multi-Drive mode include: • Lower hardware costs. Only one adapter is needed for up to five drives. Any PowerFlex 4-Class drive can be daisy-chained. • Reduces the network node count. For example, in Single mode 30 drives would consume 30 nodes. In Multi-Drive mode, 30 drives can be connected in 6 nodes.
Using Multi-Drive Mode 7-5 Additional Information • When the adapter—mounted in a PowerFlex 40/40P/400 drive or a DSI External Comms Kit— is powered up, all configured daisy-chained drives must be present before an I/O connection is allowed on the network (that is, before the drives can be controlled). If the adapter PORT indicator is steady green, the adapter is properly communicating with all drives on the Multi-Drive node.
7-6 Using Multi-Drive Mode Figure 7.7 and Figure 7.8 show wiring diagrams for using AK-U0-RJ45-TB2P terminal block connectors and terminating resistors. Figure 7.7 Connector Wiring Diagram - With Adapter in Drive To Drive 0 (PowerFlex 40/40P/400 drive with installed 22-COMM-P adapter) To To Drive 1 Drive 2 To Drive 3 120 Ohm, ¼ Watt Terminating Resistor To Drive 4 120 Ohm, ¼ Watt Terminating Resistor Figure 7.
Using Multi-Drive Mode 7-7 Understanding the I/O Image The Profibus specification requires that the terms input and output be defined from the scanner’s point of view. Therefore, Output I/O is data that is output from the scanner and consumed by the Profibus 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 configuration of the adapter Mode Jumper (J2) and adapter Parameter 11 - [DSI I/O Cfg].
7-8 Using Multi-Drive Mode Configuring the RS-485 (DSI) Network Properly configure the adapter (Single mode operation) and only the 1st drive (as shown in Figure 7.4 or Figure 7.5) on the node so that they are communicating with each other. Communication has been established when the adapter PORT indicator is solid green. When the PORT indicator is red, communication between the adapter and the drive is not established.

In this case, the returned data in the response will contain a fault code and not the parameter value data.
D-16 Notes: SLC Ladder Logic Examples
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 Profibus. 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 22-COMM-P Profibus adapter connects PowerFlex 4-Class drives to a Profibus Network.
Glossary-2 DSI (Device Serial Interface) A modification of the ModBus RS-485 serial communication protocol used by various Allen-Bradley drives and power products. 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 serial converter and PowerFlex 4-Class HIMs (22-HIM-xx) are examples of DSI peripherals.
Glossary-3 fault occurs, the data from these parameters is sent as the Logic Command Logic and/or Reference. Feedback See Reference/Feedback Flash Update The process of updating firmware in a device. The adapter can be flash updated using the controlFLASH tool or the X-Modem protocol and a 1203-SSS Smart Self-powered Serial converter (firmware 3.xxx or later). G H GSD File A file used by network configuration tools to configure the adapter.
Glossary-4 of input from the adapter to the network. The definitions of the bits in this word depend on the drive, and are shown in Appendix C. M Master See Scanner N Node Address A Profibus network can have as many as 126 devices connected to it. Each device on the network must have a unique node address between 0 and 126. NVS (Non-Volatile Storage) NVS is the permanent memory of a device.
Glossary-5 Feedback is used to monitor the speed of a drive. It consists of one 16-bit word of input from the adapter to the network. 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. A Scanner is often called Master. Status Indicators Status indicators are LEDs that are used to report the status of the adapter, network, and drive.
