PLC stands for Programmable Logic Controller. It is a digital computer that is used for automation of industrial processes(electrical & mechanical), like controlling different machines. It is also known as programmable automation controllers. What is PLC | Programmable Logic Controller
Unlike PID loop controllers, which are special-purpose devices intended to perform a single type of control function, a PLC may be instructed to do almost anything with the signals it receives from input devices. PLCs were introduced to industry as electronic replacements for electromechanical relay controls.
PLCs were introduced to industry as electronic replacements for electromechanical relay controls. In applications where relays typically control the starting and stopping of electric motors and other discrete output devices, the reliability of an electronic PLC meant fewer system failures and longer operating life.
A PLC device essentially consists of a base station with some inputs and outputs. The basic version features a processor in the central assembly, signal inputs and outputs, the interface, and an operating system. Depending on the model’s complexity, controllers may have a different number of analogue or digital inputs and outputs.
CPU is the brain of PLC with an octal or hexagonal microprocessor. Being a microprocessor-based CPU, it replaces timers, relays, and counters. Two types of processors a single bit or word processor, can be incorporated with a PLC. A bit processor is used to perform logic functions.
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). The biggest differences are that a PLC can perform discrete and continuous functions that a PC cannot do, and a PLC is much better suited to rough industrial environments.
