PAGE 31
Configuring the Adapter Setting the Node Address 3-3 If the adapter Data Rate switch (Figure 2.2) is set to ‘PGM’ (Program), the value of Parameter 03 - [DN Addr Cfg] determines the node address. We recommend not to use the default node address 63 because all new devices on the network use this address as the default address. Also, node address 63 is used for Automatic Device Recovery (ADR). 1. Set the value of Parameter 03 - [DN Addr Cfg] to a unique node address.
PAGE 32
3-4 Configuring the Adapter 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 implicit I/O.) A ‘1’ enables the I/O and a ‘0’ disables the I/O. 1. Set the bits in Parameter 13 - [DPI I/O Cfg].
PAGE 33
Configuring the Adapter Selecting Master-Slave or Peer-to-Peer Hierarchy 3-5 A hierarchy determines the type of device with which the adapter exchanges data. In a Master-Slave hierarchy, the adapter exchanges data with a master, such as a scanner (1756-DNB, 1771-SDN, 1747-SDN, and so forth). In a Peer-to-Peer hierarchy, the adapter exchanges data with one or more DeviceNet adapters connected to other drives. (The drives must have compatible Logic Command/Status words.
PAGE 34

5-2 Using the I/O Understanding the I/O Image The terms ‘input’ and ‘output’ are defined from the controller’s point of view. Therefore, output I/O is data that is produced by the controller and consumed by the adapter. Input I/O is status data that is produced by the adapter and consumed as input by the controller. The I/O image will vary based on the following: • Size (either 16-bit or 32-bit) of the Reference/Feedback words and Datalink words used by the drive.

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.
PAGE 92
5-8 Using the 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].
PAGE 93
Using the I/O 5-9 PowerFlex Digital DC Drives The Reference/Feedback value is: 25000 = Maximum Reference Speed The maximum reference speed is set using drive parameter 45 - [Max Ref Speed]. Using Datalinks A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks allow a drive parameter value to be read or written without using an Explicit Message. When enabled, each Datalink occupies two 16-bit or 32-bit words in both the input and output image.
PAGE 94
5-10 Using the I/O 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.
PAGE 95
Using the I/O 5-11 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.

Using the I/O 5-23 TIP: When using a drive that has 16-bit Datalinks (PowerFlex 70, PowerFlex 700, and PowerFlex 700H drives) to transfer a 32-bit parameter, two contiguous drive Datalink parameters (for example, Data Out A1/A2, B1/B2, and so forth) are required. To determine if a parameter is a 32-bit parameter, see the Parameter section in the drive documentation and look for a 32 symbol in the ‘No.’ column. (All parameters in PowerFlex 700 Series B drives are 32-bit parameters.

6-2 Using Explicit Messaging About Explicit Messaging Explicit Messaging is used to transfer data that does not require continuous updates. With Explicit Messaging, you can configure and monitor a slave device’s parameters on the network. Important: When an explicit message is performed, by default no connection is made because it is an ‘unconnected’ message.
PAGE 131
Using Explicit Messaging Performing Explicit Messaging 6-3 There are five basic events in the Explicit Messaging process. The details of each step will vary depending on the type of controller being used. See the documentation for your controller. Important: There must be a request message and a response message for all Explicit Messages, whether you are reading or writing data. Figure 6.

Using Explicit Messaging SLC 500 Controller Examples 6-27 The CIP messaging method provides two ways to perform explicit messaging: • Read/Write Parameter Service simplifies setup by requiring less data to be entered in message configuration screens. However, the Read/Write Parameter Service can only be used to perform single parameter read or single parameter write explicit messages. (Multiple parameter reads or writes must be performed using the Generic Get/Set Attribute Service described below.

Glossary A Adapter Devices such as drives, controllers, and computers usually require a network communication adapter to provide a communication interface between them and a network such as DeviceNet. 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-D DeviceNet adapter connects PowerFlex 7-Class drives to a DeviceNet network.
PAGE 232
G-2 Glossary Class A class is defined by the DeviceNet specification as ‘a set of objects that all represent the same kind of system component. A class is a generalization of an object. All objects in a class are identical in form and behavior, but may contain different attribute values’. Connected Components Workbench Software The recommended tool for monitoring and configuring Allen-Bradley products and network communication adapters.
PAGE 233
Glossary G-3 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 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.
PAGE 234
G-4 Glossary 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 software (version 3.01 or later), that you can use to program, monitor, control, troubleshoot, and maintain Allen-Bradley products. DriveTools SP software can be used with PowerFlex 7-Class and PowerFlex 4-Class drives, and legacy drives that implement the SCANport communication interface.
PAGE 235
Glossary G-5 HIM (Human Interface Module) A device that can be used to configure and control a drive. PowerFlex 7-Class HIMs (catalog number 20-HIM-xx) can be used to configure PowerFlex 7-Class drives and their connected peripherals. 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.
PAGE 236
G-6 Glossary The Logic Status is used to monitor the PowerFlex 7-Class drive (for example, operating state and 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, and are shown in Appendix D. M Master-Slave Hierarchy An adapter configured for a master-slave hierarchy exchanges data with the master device.
PAGE 237
Glossary G-7 Polled I/O Data Exchange A device that is configured for polling I/O data exchange sends data immediately after it receives a request for the data. For example, an adapter receives a Logic Command from the scanner and then sends back the Logic Status of the connected PowerFlex drive.
PAGE 238
G-8 Glossary 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. Status Indicators 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.
