PLC Tutorials

Before the advent of solid-state logic circuits, logical control systems were designed and built exclusively around electromechanical relays. Instead, digital computers fill the need, which may be programmed to do a variety of logical functions. As an acronym, it meant Mod ular Di gital Con troller, and later became the name of a company division devoted to the design, manufacture, and sale of these special-purpose control computers. Other engineering firms developed their own versions of this device, and it eventually came to be known in non-proprietary terms as a PLC , or P rogrammable L ogic C ontroller. The purpose of a PLC was to directly replace electromechanical relays as logic elements, substituting instead a solid-state digital computer with a stored program, able to emulate the interconnection of many relays to perform certain logical tasks. In an effort to make PLCs easy to program, their programming language was designed to resemble ladder logic diagrams.

This is an era of technology and everyone relies on technology. Technology has changed mankind a lot. Technology has the immense effect on mankind. It has basically given birth to new mankind in which men just have to design certain tools or devices for their work and then command them to work accordingly. One such device, which has the immense effect and is based on logical technology in the field of different industries, is PLC.
