Steady Drive running, no faults are present. Flashing, drive stopped An inhibit condition exists – the drive cannot be started. Check drive Parameter 214 - [Start Inhibits].
2-10 Installing the Adapter 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.
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. We HIM to Access Parameters recommend that you read through the steps for your HIM before performing the sequence. For additional information, see the drive documentation or the PowerFlex 7-Class HIM Quick Reference, publication 20HIM-QR001. Using an LED HIM Step Example Screens 1.
3-3 Configuring the Adapter Setting the Rack Address If adapter Configuration DIP Switches SW7 and SW8 (Figure 2.2) are both set to ‘On’, the value of Parameter 03 - [RIO Addr Cfg] determines the rack address. Note these points: • Although the adapter supports rack addresses between 00 and 77 octal, not all controllers recognize all of the addresses, and a Remote I/O channel can support only 32 devices. • PLC-2 controllers identify rack addresses differently than other controllers.
3-4 Configuring the Adapter Setting the Baud Rate If adapter Configuration DIP Switches SW7 and SW8 (Figure 2.2) are both set to ‘On’, the value of Parameter 05 - [RIO Rate Cfg] determines the Remote I/O baud rate. 1. Set the value of Parameter 05 - [RIO Rate Cfg] to the baud rate at which your network is operating. Port 5 Device 20-COMM-R Parameter #: 05 RIO Rate Cfg 0 57.6 kbps Value Baud Rate 0 57.6 Kbps (default) 1 115.2 Kbps 2 230.4 Kbps 2.
Configuring the Adapter Setting the Last Rack 3-5 If adapter Configuration DIP Switches SW7 and SW8 (Figure 2.2) are both set to ‘On’, the value of Parameter 26 - [Last RIO Rack] notifies the controller that this device is the last device on a specified rack. This parameter must be set to ‘1’ (Enabled) if the drive is the last device on a rack address that uses a PLC-2 controller. We recommend that you set this parameter to ‘1’ (Enabled) whenever a device is the last device on a rack. 1.
3-6 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 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].
Configuring the Adapter Setting a Fault Action 3-7 By default, when I/O communication is disrupted (for example, a cable is disconnected) or the controller is idle (in program mode or faulted), the drive responds by faulting if it is using I/O from the network.
3-8 Configuring the Adapter Setting the Fault Configuration Parameters When setting Parameter 10 - [Comm Flt Action] or 11 - [Idle Flt Action] to ‘Send Flt Cfg’, the values in the following parameters are sent to the drive after an I/O communication fault and/or idle fault occurs. You must set these parameters to values required by your application. Parameter Description 14 - [Flt Cfg Logic] A 16-bit value sent to the drive for Logic Command.
Configuring the Adapter The following parameters provide information about the status of the adapter. You can view these parameters at any time. Parameter Description 04 - [RIO Addr Actual] The rack address used by the adapter. This will be one of the following values: • The address set by the Rack Address Rotary Switches. • The value of Parameter 03 - [RIO Addr Cfg] if adapter Configuration DIP Switches SW7 and SW8 are both set to ‘On’.
3-10 Configuring the Adapter Updating the Adapter Firmware The adapter firmware can be 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 updating firmware over the network, you can use the Allen-Bradley ControlFLASH software tool, the built-in update capability of DriveExplorer Lite or Full software, or the built-in update capability of DriveExecutive software.
Chapter 4 Using Discrete and Block Transfer I/O This chapter provides information and examples about using I/O to control a connected PowerFlex drive.
4-2 Using Discrete and Block Transfer I/O Understanding the I/O Image Figure 4.1 (1/4 rack) and Figure 4.2 (1/2 rack) show how data is transmitted between a controller and drive. Rack Size Reference Source Feedback Destination Datalinks 1/4 Block Transfer I/O Block Transfer I/O Block Transfer I/O 1/2 Discrete I/O Discrete and Block Transfer I/O Block Transfer I/O Figure 4.
Using Discrete and Block Transfer I/O Figure 4.
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 shows a 1/4 rack I/O image, and Figure 4.2 shows a 1/2 rack I/O image.
Using Discrete and Block Transfer I/O Size Valid Values 16-bit -32768 to 32767 32-bit -2147483648 to 2147483647 4-5 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.
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].
Using Discrete and Block Transfer I/O Block Transfer I/O Image 4-7 The Block Transfer I/O image is a Block Transfer message that contains eighteen 16-bit words. It reserves two words for the Reference/Feedback and four words for each Datalink (in case 32-bit values are used). Figure 4.
4-8 Using Discrete and Block Transfer I/O 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) is used, word 1 is not used during writes and is read as zero (0) during reads.
Using Discrete and Block Transfer I/O 4-9 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.
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 = 0001hex = 0001binary = 216 = 65536 LSW = 0003hex =3 Engineering Value = 65536 + 3 = 65539 Parameter 10 Displayed Value = 6553.

5-4 Using Block Transfer Messaging Block Transfer Read Structure to Receive Block Transfer Messages Data Field Description Word 0 Length The least significant byte contains the length of the actual Explicit Message in bytes. The most significant byte is always zero.
Using Block Transfer Messaging 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.
5-6 Using Block Transfer Messaging The following table describes the main events and what a program is monitoring when performing Block Transfer messaging. Item Event Description ➊ BTW Request Before initiating a Block Transfer message, bit 8 must be 1. This setting indicates that the adapter and drive are communicating, so a Block Transfer message will reach the drive. Before initiating a Block Transfer Write message, bit 9 must be 1.

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 Remote I/O. 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-R Remote I/O adapter connects PowerFlex 7-Class drives to a Remote I/O network.
G-2 Glossary CIP (Common Industrial Protocol) CIP is the transport and application layer protocol used by some scanners on Remote I/O networks. The protocol is used for implicit messaging (real-time I/O) and Block Transfer messaging (configuration, data collection, and diagnostics). Client/Server Network This type of network has a server respond to client requests. For example, the Remote I/O adapter is a server of data and responds to the requests of client devices (for example, controllers).
Glossary G-3 DPI Peripheral A device that provides an interface between DPI and a network or user. Peripheral devices are also referred to as ‘adapters’ or ‘modules’. The 20-COMM-R adapter, 1203-USB or 1203-SSS converter, and PowerFlex 7-Class HIMs (20-HIM-xx) are examples of DPI peripherals. DPI Product A device that uses the DPI communication interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex 7-Class drive is a DPI product.
G-4 Glossary H 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.
Glossary P G-5 Ping A message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control. PowerFlex 7-Class (Architecture Class) Drives The Allen-Bradley PowerFlex 7-Class family of drives supports DPI and, at the time of publication, includes the PowerFlex 70, PowerFlex 700, PowerFlex 700H, PowerFlex 700S, PowerFlex 700L, and PowerFlex 7000.
G-6 Glossary Remote I/O Network Remote I/O is an Allen-Bradley network interface originally designed to link remote I/O racks to PLCs over appropriate cables (‘Blue-Hose’). Remote I/O supports remote, time-critical control communications between a client controller and server devices such as a Remote I/O adapter and its connected host drive. A server device will accept only the packets that are addressed to it. Remote I/O also supports Block Transfer messaging.
