WOODWARD 9907-247调速器
将I/O配置保存到控制器
将网桥和驱动器/选项模块添加到I/O配置后，您可以必须将配置下载到控制器。您还应该保存配置到计算机上的文件。
1.从RSLogix 5000对话框的通信菜单中，选择下载。2.单击下载将配置下载到控制器。
成功完成下载后，RSLogix 5000软件进入在线模式，I/O OK框位于对话框应呈绿色稳定显示。
3.从“文件”菜单中，选择“保存”。如果这是您第一次保存项目，将显示“另存为”对话框。导航到文件夹，键入文件名，然后单击“保存”保存配置到计算机上的文件。
4.控制器和选项模块中启用的任何数据链路I/O配置期间，还必须在驱动器中配置。每个使用的数据链路必须分配给驱动器中的特定参数或连接的外围设备（请参阅选择主从或对等第39页上的层次结构（仅适用于适配器模式）或自定义对等I/O配置（第42页）。如果不这样做，控制器将接收或发送占位符数据，而不是实际驱动器或外围设备参数价值观
5.将控制器置于远程运行或运行模式。关于I/O消息在基于CIP的网络（包括EtherNet/IP）上，I/O连接用于
传输控制PowerFlex驱动器的数据并设置其参考。输入/输出也可用于在PowerFlex 750系列中与Datalinks之间传输数据驱动器。选项模块包括逻辑命令、逻辑状态、参考、通用以太网模块配置文件的反馈和内存分配（均为32位字）。此基本I/O必须始终使用RSLogix 5000软件在EtherNet网桥中配置。附加I/O，如果需要，可以使用最多16个数据链接来设置写入数据和/或最多16个读取数据的数据链接。使用这些数据链接的任何组合时，请添加一个每个数据链接到基本I/O输入大小和/或输出大小的32位字。
第3章，配置选项模块
第4章，配置I/O，讨论如何配置选项模块和控制器在网络上执行所需的I/O。术语表定义了不同的选项。
本章讨论配置选项后如何使用I/O模块和控制器。术语输入和输出是从控制器的角度定义的。
因此，输出I/O是由控制器生成并由选项模块。输入I/O是由选项生成的状态数据模块，并作为控制器的输入使用。
I/O映像将根据在以下方面：
•驱动器的32位数据链路的数量（主机DL From Net 01-16和主机DL To Net 01-16）。
•仅ControlLogix/CompactLogix控制器使用的驱动器配置文件
在RSLogix 5000软件中（驱动16.00或更高版本中的附加配置文件，或所有版本中的通用配置文件）。
Saving the I/O Configuration to the Controller
After adding the bridge and drive/option module to the I/O configuration, you must download the configuration to the controller. You should also save the configuration to a file on your computer. 1. From the Communications menu in the RSLogix 5000 dialog box, choose Download.2. Click Download to download the configuration to the controller. When the download is successfully completed, RSLogix 5000 software goes into the Online mode and the I/O OK box in the upper-left of the dialog box should be steady green. 3. From the File menu, choose Save. If this is the first time you saved the project, the Save As dialog box appears. Navigate to a folder, type a file name, and click Save to save the configuration to a file on your computer. 4. Any Datalinks that were enabled in the controller and option module during I/O configuration must also be configured in the drive. Each Datalink being used must be assigned to a specific parameter in the drive or connected peripheral (see Selecting Master-Slave or Peer-to-Peer Hierarchy (Adapter mode only) on page 39 or Custom Peer I/O Configuration on page 42). If this is not done, the controller will receive or send placeholder data instead of actual drive or peripheral parameter values. 5. Place the controller in Remote Run or Run Mode.
About I/O Messaging
On CIP-based networks, including EtherNet/IP, I/O connections are used to transfer the data which controls the PowerFlex drive and sets its Reference. I/O can also be used to transfer data to and from Datalinks in PowerFlex 750-Series drives. The option module includes the Logic Command, Logic Status, Reference, Feedback, and memory allocation for the Generic Ethernet module profile (all as 32-bit words) in the controller’s I/O image. This basic I/O must always be configured in the EtherNet bridge using RSLogix 5000 software. Additional I/O, if needed, can be set using up to 16 Datalinks to write data and/or up to 16 Datalinks to read data. When using any combination of these Datalinks, add one 32-bit word for each Datalink to the basic I/O Input Size and/or Output Size. Chapter 3, Configuring the Option Module, and Chapter 4, Configuring the I/O, discuss how to configure the option module and controller on the network for the required I/O. The Glossary defines the different options. This chapter discusses how to use I/O after you have configured the option module and controller.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 option module. Input I/O is status data that is produced by the option module and consumed as input by the controller. The I/O image will vary based on the following: • How many of the drive’s 32-bit Datalinks (Host DL From Net 01-16 and Host DL To Net 01-16) are used. • ControlLogix/CompactLogix Controllers only—The drive profile used in RSLogix 5000 software (drive Add-on Profile in version 16.00 or later, or Generic Profile in all versions).
