从CotrolLogix PLC的SD卡中读取程序
Use Case:
Let’s assume an OEM has a customer that is not familiar with Logix or does not have the appropriate software required to perform a download. The OEM can send files via email to the customer that can be loaded directly into a controller using an SD card. The steps below define the procedure for performing this task.
使用案例
让我们假设OEM有这样的一个客户,该客户不熟悉Logix或不具备执行下载相应的软件,但是有下载程序的需求。该OEM可以通过电子邮件发送程序文件给客户,将这个文件直接加载到控制器使用的SD卡中,就可实现程序的下载。下面的步骤定义执行此任务的过程。
- The OEM must have the exact controller type and series as the customer. The OEM downloads the application to the controller. The controller must be in Program Mode.
该OEM必须有与客户的PLC,类型和系列严格相同的PLC。OEM将下载程序到PLC中。控制器须在Program模式。 - Insert BLANK SD card into the controller.
在PLC内插入【空白】的SD卡 - Open Controller Properties window, click on the Nonvolatile Memory tab.
打开PLC属性窗口,点击至 Nonvolatile Memory标签页 - Click the ‘Load / Store’ button.
点击“Load / Store”按钮 - Select ‘On Power Up’. This will load the project from the SD card when the controller is powered up.
选择“On Power Up”,这样,PLC上电时会将SD卡内的程序上载到PLC内。 - Click the ‘<– Store’ button.
点击“<– Store“按钮(存储) - Read the warning message. Click ‘Yes’ when you’re ready to write the files to the SD card.
阅读警告信息,如果确认向SD卡写入文件则单击“Yes” - Click ‘OK’ on the dialog box that acknowledges that it may take up to 3 minutes to complete.
- After the program has been written to the SD card, remove it from the controller.
当程序写进SD卡后,从PLC上移除。 - Place the SD card in a card reader and open the contents on a PC.
在电脑上打开该SD卡 - If a blank SD card was used, the contents should have a ‘Logix’ folder.
如果该SD卡已经写入文件,里面将会有一个名为“Logix“的文件夹
NOTE: At this point, the ‘Logix’ folder contains everything required to load the application in a controller on power-up. - Copy the ‘Logix’ folder to the PC.
复制文件夹至电脑 - The OEM can then zip the ‘Logix’ folder and email the folder to the end customer.
OEM可压缩这个文件夹并发送至EU - Unzip the ‘Logix’ folder.
解压缩 - Acquire a Secure Digital (SD) card. All controllers ship with an SD card. It is advised to retrieve the SD card from the target controller in this example.
获取一个SD卡,所有的控制器都配备有一个SD卡,建议就使用目标PLC上的SD卡
NOTE: It is recommended that you use an SD card purchased from Rockwell Automation. These SD cards are industrial certified and are better suited for a manufacturing environment. Standard SD cards may operate correctly, however they are not tested by Rockwell Automation to verify function and performance.
建议您使用的SD卡是从罗克韦尔自动化购买的。 这些SD卡经过工业认证,更适合于制造环境。 标准的SD卡也可以正常运行,但是它们不是由罗克韦尔自动化测试验证功能和性能。 - Insert an SD card into the PC. If the SD card was removed from a controller, be sure to backup all files.
将SD卡插入电脑,如果SD卡已经从PLC取出,一定确认备份好所有文件。 - Delete all files on the SD card.
删除SD中所有文件 - Copy the ‘Logix’ folder onto the SD card.
复制文件夹到SD卡内 - Remove the SD card from the PC and place it into the target controller.
从电脑移除SD卡,并插入目标PLC。 - Switch the controller to REM or PROG mode.
将PLC切换至REM或PROG模式。 - Cycle Power on the controller.
将PLC断电,并重新将PLC上电。
OEM Procedure:
End Customer Procedure:
NOTE: During the boot sequence, the SD LED will illuminate indicating the controller is loading from the SD card. Controllers that have an LCD display will display ‘LOAD’. The entire sequence may take more than a minute, depending on the size of the application.
在启动过程中,SD 指示灯亮起标明PLC正从SD卡加载程序。 PLC有一个液晶显示屏会显示“LOAD”。 整个过程可能需要超过一分钟,这取决于应用程序的大小。
