1 新建工程
型号根据所选 HMI 型号创建
2 创建页面
添加设备变量
点击设备管理 添加 Modbus RTU 设备
根据需求添加不同的 modbus 设备，对于驱动方面的问题和介绍可以参考，本案例将以 Modbus RTU 为基本组态案例进行讲解 https://help.simtutai.cn/docs/ModBus-qu-dong
添加接口
分别对模拟器和 hmi 添加接口并设置协议参数
添加设备变量
选择设备型 根据地址添加变量。
构建页面
根据需求构建页面
3 运行工程
在添加了模拟器接口后，右键工程，运行程序并打开 modbus 测试软件。此处打开的为 modbus slave。modbus 软件可以通过 https://help.simtutai.cn/docs/HMI-fu-zhu-tiao-shi-ruan-jian 获取
通讯成功显示如下
4 变量测试
可以在模拟器上 对设备变量进行修改 点击 ✔ 之后 modbus slave 自动同步
对于 10 地址的变量，此处设置的是浮点型的变量，单精度浮点型为4个字节，因此占用的地址为10，11。
如果软件上设置的地址默认容量为 10，就会出现读不到地址的问题。会出现程序连接状态不稳定的情况，读写延迟或者不成功的问题。
可以按照下列方式对软件进行设置
