PLC automation uses programmable logic controllers (PLCs), which are rugged industrial computers, to control and automate industrial processes and machinery. These systems have largely replaced older relay logic for their flexibility, reliability, and ease of programming through software, making them essential for industries like manufacturing, energy, and transportation. A PLC works by continuously monitoring inputs from sensors, processing that information with its CPU based on programmed logic, and then sending commands to output devices like motors and valves to perform actions. I can develop and install automated systems for medium to large companies to help better organise plants, sites and warehouses with less effort.
