What is a PLC and Why is PLC Programming Important?
Understanding Programmable Logic Controllers (PLCs)
A PLC is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or lighting fixtures. Unlike traditional computers, PLCs are ruggedized for harsh environments and designed for real-time control.
Significance of PLC Programming
PLC programming is the process of creating instructions that a PLC uses to control connected devices. Proper programming ensures safety, efficiency, and reliability in automated systems. Learning to program PLCs is crucial for designing, troubleshooting, and maintaining automation systems across various industries.
