C# OPCServer：使用KEPServer安装方法_如何添加仿真器与添加西门子S7PLC

OPCServer：使用KEPServer

https://www.cnblogs.com/ioufev/p/9366877.html

1.下载安装

实际OPCServer使用（450M，中文，破解时间限制）：KEPServer V6，百度网盘，密码: ykj2

2. 添加仿真器或者硬件PLC S7-300，S7-1200

仿真器就选：Simulator

西门子硬件就选：siemens TCP/IP ethernet,

如果连接硬件：参考这里：https://www.cnblogs.com/txwtech/p/15218280.html

记得输入PLC 的IP

标记里面的地址：K0003是随便写的。连接了硬件PLC，就输入PLC的实际需要操作的地址即可。

c#连接KEPServer后，写入数据，就可以观察其变化
