树莓派2的Modbus协议(主)是指树莓派2作为Modbus通信协议的主设备,用于与其他Modbus从设备进行通信。Modbus是一种常用的工业通信协议,用于在自动化系统中传输数据。Modbus协议分为Modbus RTU和Modbus TCP两种形式,其中RTU是基于串口通信的,而TCP是基于以太网的。 树莓派2作为Modbus主设备,可以通过串口或以太网接口与Modbu...
Modbus TCP/IP是一种基于TCP/IP协议的工业通信协议,用于在工业自动化系统中实现设备之间的数据通信。它是Modbus协议的一个变体,通过以太网进行通信,支持异步传输模式,具有高效、可靠、灵活等特点。 在Raspberry Pi上使用PyModBus可以实现Modbus TCP/IP通信。PyModBus是一个Python编程语言的Modbus协议库,可以用于创建Modbus...
