將I/O配置保存到控制器
將網橋和驅動器/選項模塊添加到I/O配置后,您可以必須將配置下載到控制器。您還應該保存配置到計算機上的文件。
1.從RSLogix 5000對話框的通信菜單中,選擇下載。2.單擊下載將配置下載到控制器。
成功完成下載后,RSLogix 5000軟件進入在線模式,I/O OK框位于對話框應呈綠色穩定顯示。
3.從“文件”菜單中,選擇“保存”。如果這是您第一次保存項目,將顯示“另存為”對話框。導航到文件夾,鍵入文件名,然后單擊“保存”保存配置到計算機上的文件。
4.控制器和選項模塊中啟用的任何數據鏈路I/O配置期間,還必須在驅動器中配置。每個使用的數據鏈路必須分配給驅動器中的特定參數或連接的外圍設備(請參閱選擇主從或對等第39頁上的層次結構(僅適用于適配器模式)或自定義對等I/O配置(第42頁)。如果不這樣做,控制器將接收或發送占位符數據,而不是實際驅動器或外圍設備參數價值觀
5.將控制器置于遠程運行或運行模式。關于I/O消息在基于CIP的網絡(包括EtherNet/IP)上,I/O連接用于
傳輸控制PowerFlex驅動器的數據并設置其參考。輸入/輸出也可用于在PowerFlex 750系列中與Datalinks之間傳輸數據驅動器。選項模塊包括邏輯命令、邏輯狀態、參考、通用以太網模塊配置文件的反饋和內存分配(均為32位字)。此基本I/O必須始終使用RSLogix 5000軟件在EtherNet網橋中配置。附加I/O,如果需要,可以使用最多16個數據鏈接來設置寫入數據和/或最多16個讀取數據的數據鏈接。使用這些數據鏈接的任何組合時,請添加一個每個數據鏈接到基本I/O輸入大小和/或輸出大小的32位字。
第3章,配置選項模塊
第4章,配置I/O,討論如何配置選項模塊和控制器在網絡上執行所需的I/O。術語表定義了不同的選項。
本章討論配置選項后如何使用I/O模塊和控制器。術語輸入和輸出是從控制器的角度定義的。
因此,輸出I/O是由控制器生成并由選項模塊。輸入I/O是由選項生成的狀態數據模塊,并作為控制器的輸入使用。
I/O映像將根據在以下方面:
?驅動器的32位數據鏈路的數量(主機DL From Net 01-16和主機DL To Net 01-16)。
?僅ControlLogix/CompactLogix控制器使用的驅動器配置文件
在RSLogix 5000軟件中(驅動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).
