本教程采用HslCommunication PLC模拟工具，模拟三菱PLC接入腾龙边缘网关一体机（T2000）内置的AIoTedge，演示教程可以导入至您的NodeRED环境直接使用。
HslCommunication是一个专注于工业通信的开源项目，提供了丰富的通信协议支持，适用于各种工业自动化场景。它能够实现与多种工业设备如PLC、机器人、传感器、仪表等的数据通信，还能支持不同程序之间的数据交换，包括不同编程语言（如C#、Java、Python）编写的程序之间的通信，以及程序与网页、本地电脑与云服务器之间的数据传输。腾龙一体机（T2000）内置的AIoTedge能够很好的与HslCommunication搭配调试PLC。
[类型修饰符]<.位偏移量><,数组长度>
X0,8 – 前 8 个输入
TS190 – 定时器 290 的状态（布尔值）
TN190 – 定时器 290 的经过时间值（整数）
CS190 – 计数器 190 的状态
CN220 – 计数值（双整数，因为它超过 200）
DFLOAT1000 – 从 D1000 开始的浮点值（包括 D1001，因为浮点数需要 2 个字）
D2000,5 – 从 D2000 开始的 5 个值
RDINT80 – R80 和 R81 作为 DINT
RSTR30,10 – 从 R30 开始的 10 个字符（5 个字）的字符串
S5 – S5 的布尔值
RFLOAT20,5 – 从 R20-21 开始到 R28-29 结束的浮点值
Y010 – Y010 处的输出（实际上是第 9 个输出，因为输出的顺序是 Y000-Y008，然后是 Y010）
D1000.2 – 字 D1000 的位 2
D1000.2,5 – 从 D1000.2 开始的 5 位
