说明：Client节点作用于和OPC-UA服务端进行通信。

1、准备工作

1-1、OPC-UA 服务端

模拟器名称：OPC UA Simulation Server 。

官方下载地址：

https://www.prosysopc.cn/products/opc-ua-simulation-server

备用下载：

prosys-opc-ua-simulation-server-2.3.2-146.zip

1-2、服务端软件使用

1、打开模拟器【Prosys OPC UA Simulation Server】，自动创建【Server】。

Node-RED软网关使用手册-最佳实践（OPC-UA【Client】读写—示例）

需要注意的是：

运行状态，是否变为【Running】
复制OPC连接地址【opc.tcp://windows10.microdone.cn:53530/OPCUA/SimulationServer】

注意这个地址改为自己对应的IP【opc.tcp://192.168.1.27:53530/OPCUA/SimulationServer】

2、关闭模拟器上动态数据。

需要注意的是：下图中，在标记2处，【取消勾选】；

作用：后续演示写入时，避免数据一直在动态更新，无法看到写入数据。

2、OPC-UA 读写操作

2-1、示例代码
