MODBUS是一种广泛使用的工业通信协议,它允许通过串行线路在不同设备之间进行通信和数据交换。RS485模块是一个在ESP32上实现MODBUS协议的硬件。在本教程中,我们将使用RS485模块在ESP32开发板上创建一个MODBUS主机和从机设备,并实现与MODBUS主机的通信。实验效果多个Modbus(Server)从机设备与一个Modbus主机(Client)设备...
Is there any way just change the byte order in esp-idf Modbus library? This is my solution at the moment: Code: Untitled.cpp Select all void DataExchange::updateModbusArray() { for(int i=0; i < _numElements; i++) { _modbusArray[i*4+0] = *((char*)_dataArray + i*4+2);...
Unfortunately, the current implementation of the ESP_Modbus library does not allow this. It is not possible to install several instances of master or several instances of a slave at the same time because they share the same FSM - final state machine (one master and one slave is allowed at ...
