![]() There is a wide range of PLC functions like timing, counting, calculating, comparing, and processing various analog signals. ![]() Since then PLC has revolutionized the industrial and manufacturing sectors. PLCs were invented by Dick Morley in 1964. They both have a power supply, a CPU (Central Processing Unit), inputs and outputs (I/O), memory, and operating software (although it’s a different operating software). PLCs share many features of the personal computer you have at home. PLCs are used to automate industrial processes such as a manufacturing plant’s assembly line, an ore processing plant, or a wastewater treatment plant. A PLC is a computer specially designed to operate reliably under harsh industrial environments – such as extreme temperatures, wet, dry, and/or dusty conditions. PLC stands for “Programmable Logic Controller”.
