Design Of Programmable Logic Controllers To Adjust The Temperature In The Temporary Storage Buns Of Cotton

Abstract

In this scientific article, a SCADA system for continuous monitoring of temperature in temporary storage bunts of cotton was developed. The system was designed using 24-bit programmable logic controllers (PLC) and thermocouple sensors (TS), as well as analog digital converters (ADC).  The main objectives of the project in the article are:

-     Formatting of signals from thermocouple sensors (TS), development of a method of ratiometric change of the sensor;

-     Programmable logic controllers and signal routing, system protection;

-     Designing programmable logic controllers, as well as developing and creating a sensor-PLC module for measuring temperature and sending signals to PLC.
