Program Plan Intro
Programmable Logic Controller (PLC):
- • Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process.
- • PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
- • The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
- • When compared to general PC, a PLC is available in small and tiny sizes.
- • The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by control
programming language.
