Python implements ModBusRTU server
It is a simple matter to implement the ModBusRTU server based on serial port communication in python, which can be achieved through the pymodbus module. 1. A Demo and the problems it causes 1. A Demo import asyncio import json import threading import time from pymodbus.server import StartSerialServer, ServerAsyncStop from pymodbus.datastore import ModbusSequentialDataBlock, ModbusServerContext, ModbusSlaveContext […]

ModbusRTU protocol encapsulation, control RJ45 alarm, just copy it and use it~
This article only operates on the writing holding register HoldingRegister, and other types of register methods are also in the ModbusWriteOrRead class, which can be tested by yourself. Alarm device model (USB version): JD01AX07 01 Equipment appearance and lighting: Documentation says – part: Note: Take the binary command with the first green light on in […]
C# develops serial port debugging assistant to realize modbusRTU communication
Let’s do a project for everyone today, come with me, don’t miss it when you pass by, and see how the big V plays C# industrial software development. Serial communication process Hardware products: Serial port RS232 temperature and humidity sensor, used to test the temperature and humidity of the outside world, such as warehouses, greenhouses, […]
python-batch extract plain text in srt files
python-batch extract plain text from srt files 1. Function introduction In order to facilitate daily use, I packaged the program for batch extraction of plain text in srt files into exe files, so that there is no need to install the python environment and related libraries too. The current version of the program can select […]
Process scheduling algorithm FCFS, SJF (SPF), SRT, RR principle and code implementation
Regarding the code implementation of the process scheduling algorithm, I wrote one two years ago (the portal is here), but the writing is not very good. To be honest, I can’t understand the code written at that time when I look back, because it is too written. It’s messy, and the code redundancy is very […]
