（3）程序下载 Download
下载当前正在的编辑的流程图程序或JC程序有3种方法：
There are three ways to download the current edited flowchart program or the JC program:
①点击工具栏的下载按钮；
Click the Download button on the toolbar;
②使用菜单栏“工具（T）”菜单下的“下载当前程序（D）”；
Use the "Download Current Program (D)" under the" Tools (T)" menu in the menu
bar;
③使用快捷方式，F5-下载当前JC程序，F6-下载当前流程图程序。
Use shortcuts, F5- download the current JC program, F6- download the current flowchart program.
程序下载前需要先连接USB下载线缆。Ccon102控制器连接好USB线缆后控制器的显示屏上会进入下载界面。如果没有连接好USB线缆，而直接下载，VJC的下载界面也会有提示。
The program needs to connect USB download cable before downloading. The Ccon102 controller connects the USB cable to the download interface on the display of the controller. If the USB cable is not connected, and download directly, the VJC download interface will also be prompted.
程序中如果有语法错误，会无法通过编译，也会导致程序无法下载。流程图程序的语法错误一般出现在自定义模块中。JC代码的语法错误会显示在“交互信息窗口”中，双击错误行，会在JC代码窗口进行自动定位，方便您的修改。
If there is a syntax error in the program, it will not be able to compile and will cause the program to be unable to download. The syntax error of the flowchart program generally appears in the custom module. The syntax error of the JC code will be displayed in the Interactive Information Window, double-clicking the error line will automatically locate in the JC code window to facilitate your modification.
