PLC's Definition A PLC is a Programmable Logic Controller . In other words, it is an industrial computer used as a standalone unit and can be used in a network of PLCs to automatically control a process or perform a specific function. To take information from the outside world such as temperature of a liquid, level in a tank, speed of an object etc, PLC uses different forms of connected sensors. Future of industrial automation would be great if automation people use PLC to control processes. However, the real world signals are transformed into electrical signals by the external sensors and relayed to the PLC that turn processes the electrical signals and uses them to complete its pre-programmed task. Introduction PLCs are used in various places and many of the previous automation processes have been upgraded. This upgraded automation has more flexibility and is simple to alter also. This in turn lends itself to have a more efficient and portable process. On the other h
