Program Plan Intro

Programmable Logic Controller (PLC):

  • 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 Personal Computer (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 controlling programming language.

Set-point:

  • Set-point is a component of closed-loop control system and abbreviated as SP.
  • It refers to the input which determines the operating point for the process.
  • In industrial systems, the determined set point can be limited by physical or process restraints.
