www.justengg.com www.justengg.com Basic Introduction to Programmable Logic Controller PLC PLCs are the main heart of the automation system. PLC is the controller used to control the plant/process/system/machine PLC is digital Programs use to be industrial computer that monitor Input makes decisions and output to controls automate process Machine. Programmable Logic Controller PLC used in the industry control the machine. Programmable Logic Controller PLC is designed to read digital and analog input various sensors. History : The First programmable logic controller PLC specified in 1968 by the Hydromantic division of the General Motors Crop. The first models name was invented. the Second models came in 1970 communication abilities appears and third Model came 1980 Standardization on communication on protocols 1990 Standardization on programming language PLC control System : Programmable logic controller PLC in industrial digital computer control system input or output devices to control and easy to make decisions PLC controller is used to control the plant/process/system/machine PLC Advantages : • PLC is programmer language easy to understand • Very fast • Easy to change logic i.e. flexibility • Low power consumption • Easy maintenance due to modular assembly
