和Add-ins有什么区别
附加组件是功能或数据包，它们为EPLAN产品变体增加了额外的功能或提供了额外的数据。这些附加组件可以是EPLAN提供的，也可以是用户创建的。在许多情况下，EPLAN附加组件的功能包也可以作为独立的独立版本提供。例如，EPLAN Fluid既可以作为独立版本使用，也可以作为EPLAN Electric P8 Professional的附加组件购买。
Add-ons = Add-ins + 设置 + 图片 + 脚本 + XML + …
一系列内容组成的扩展包。而Add-in只是指由dll组成的插件程序。
每个附加组件都有相同的文件夹结构。当文件夹名称是可选并且可以由附加组件开发者更改时，这些名称会用 <> 标记。
注意： 这个附加组件文件夹可以存在于磁盘上的任何位置！
一个附加组件总是由相同的文件夹结构组成，基本上看起来是这样的：
<Add-on>
<Add-on version>
BIN 这里安装了附加组件的所有二进制文件。
CFG 这里安装了所有的XML文件和 install.xml 文件。install.xml 文件是基础数据。
文件夹的名称在 install.xml 中列出，用于将数据复制到EPLAN基础数据中。
<Images>
<Scripts>
<XML>
<…>
最重要的文件是 install.xml。它包含了关于附加组件和EPLAN版本的所有信息。
本段展示了一个由 EplAddonUtility.exe 创建的 install.xml 文件示例。
提示： 有关如何使用 EplAddonUtility.exe 创建附加组件及应遵循的条款和条件的更多信息，请参阅 "EplAddonUtility" 文档。
