点击上方菜单栏的【Connection】->【Connect...】或F3快捷键直接打开 Connection 默认选择的是Modbus TCP/IP,下方是远程Modbus Server的设置,像网络调试助手一样连接服务器一样,需要设置服务器的Ip和Port.其余参数使用默认传参数即可。之后点击【OK】按钮即可。 ④连接成功与更改数值 连接成功如下: 更改数据操作: 鼠标...
modbusserialclient() `ModbusSerialClient`可能是用于Modbus通信的一个库或者类的名称。Modbus是一种用于工业自动化领域的通信协议,它允许设备之间通过串行通信或网络通信进行数据交换。在这里,我将提供一个简单的Python示例,使用`minimalmodbus`库创建Modbus串口客户端。 首先,确保你已经安装了`minimalmodbus`库。你可以...
client = ModbusSerialClient() client.connect(port='COM1', baudrate=9600, databits=8) ``` 4.读取寄存器数据 一旦成功连接到设备,我们就可以开始读取寄存器数据。使用ModbusSerialClient()的read_holding_registers()方法可以读取设备的保持寄存器数据。 ```python #读取保持寄存器地址为0的数据 result = client...
基于python的ModbusSerialClient 基于Python的旅游数据分析, 这里,数据来源是马蜂窝http://www.mafengwo.cn/。首先,马蜂窝对爬虫相对友好,另外,使用马蜂窝也是我和女友出游的习惯,在计划去某地前都会先在马蜂窝上查查攻略,不得不佩服很多小伙
