Introduction
A Programmable Logic Controller or PLC was first created for General Motors in the 1968 in order to provide services to the automotive industry. PLC includes logic in which it replaces wires with electronic controls and relay system. PLC was in demand during the early 21st century and it was used heavily in the packaging, manufacturing and variety of high output production lines.
Since its implementation is normally in harsh environments, the PLC is to stand high vibrations and noise level. It is able to control most of the inputs and output from getting sensor value and giving motor output. It is able to display the values in LCD displays and have been used to automated most of the manufacturing processes.
PLC is a programmable microprocessor which is programmed using a specialized computer language. Usually, the PLC is programmed through a wired connection between a pc and the PLC itself.
Objective
1) Program PLC’s to control robotic systems.
2) Analyse and
