Step:
1.Define objective e.g. if temperature of heater goes
beyond 200 degree celcius the fan made on untill
temperature reaches 150degree celcious.
2. then the given objective is converted in programm by
using set of instruction it may be Plc programming language
s5 or s7 in Ladder logic or STL
3. install program into plc using required input from
module.
4.then start plc it works as per instruction.
5.Requred to connect plc output to field contactar,
6.connect sensor feedback to plc system.
