Programmable logic controllers (PLCs) are the workhorse computing systems that help to coordinate and harmonize functions performed by the multitude of sensors, actuators, conveyors and many other ...

PLCs, or programmable logic controllers, are widely used in industrial automation and smart factories to control sensors and actuators. Sensors are devices that measure physical properties, such ...

The Programmable Logic Controller (PLC) is the workhorse of Industrial Control systems. It uses digital and analog I/O modules to interface to sensors, actuators and other equipment. These I/O modules ...

Logic controllers are frequently assigned the responsibility of controlling and monitoring a vast array of sensors and actuators. Thus, their broad I/O (input/output) configurations set them apart ...

Programmable Logic Controllers Handbook Vol. 1 . This 100+ page handbook deals with the PLC hardware and software and all the surrounding systems that must be compatible to achieve a safe and reliable ...

Development, testing and validation of a small battery-powered hand-held programmable-logic-device (PLD) based temperature and relative-humidity sensing, processor and display system platform, to be ...

This paper presents the design and implementation of speed control for a brushless direct current (BLDC) motor using a complex programmable logic device (CPLD). Implementation of speed control is ...

Well it’s been another extraordinary summer of weather. One stage of the Tour De France had to be cut short due to a snow blizzard in July, that closed a mountain pass. To be more accurate, it was the ...

A Programmable Logic Controller is “a small industrial computer originally designed to perform the logic functions executed by electrical hardware (relays, switches, and mechanical timer/counters),” ...

Given the above, the main purpose of this study was to developing a programming system and evaluating an automated control system for four fertigation management-types in an experiment with tomatoes ...
