The main purpose of PLC in industries is the automation of all processes instead of manually control them.
PLC ( programmable logic controller) is used for processing the data and controlling the machines and exécutes a different comand according to a program
PROGRAMMABLE LOGIC CONTROLLER offer a system with computer flexibility:
1. Suited to withstand the industrial environment
2. Has simplicity of operation
3. Maintenance by plant technicians and
4. Reduce machine down time and provide expandability for future.
PLC is the backbone of industry, millions of processes must done every day, controlling these tasks by humans are quit diffcult, so we need help by machines , but still that human are playing a majour role in supervisour and controll.
The role of PLC in the industry is : processing the DATA from sensors and controlling the machinery by giving the command according to a program
PLC is a programmable logic controller -which processing the data from sensors and controlling the machine and giving different commend
