在OPC DA通讯测试时总是避免不了要配置DCOM，我习惯是在虚拟机中装这些通讯测试软件，每次安装都需要再次手动配置，感觉很是麻烦
因此，查找资料，了解到可以用dcomperm这个软件来在命令行下进行dcom的配置，花了些时间研究，以KepServer6.4为例，写了一个配置脚本，在此留下记录，方便后续参考

在命令行下运行dcomperm，得到帮助如下图:

我使用的配置脚本如下，复制粘贴到记事本，保存为bat文件，以管理员权限执行，执行结果会记录在DCOMConfig.log日志文件中。

仔细看代码中如下图所示位置:

上图红框中是是应用程序ID，如果你使用的软件和我的版本不一致(或者不是这个OPCServer服务端)，需要更换成你所使用软件的应用ID，查看ID方法如下图所示:

dcomperm软件自行下载.我所使用的信息如下图:

再次说明，要以管理员权限运行...
