Abstract

The PLC (programmable logic controller) is a microprocessor-based regulator or controller that is used for implementation of logical functions for controlling industrial processes, where in automation field is also known as an ‘‘industrial computer”. As automation device that includes microprocessor, the manners of communication between PLC and the developer or operator are realized through the graphical and textual languages, where since the beginning of utilization, the basic or most used language for implementation of logical functions is the graphical language called LLD (ladder logic diagram), but with rapidly development and advancing techniques in years, there are also created other different languages where operators have options or other alternatives to choose, based on their abilities and skills. Thus, the most applied languages for PLC programming are unified and standardized according to IEC 61131. In this article GRAFCET (graph for step transition control) is presented as one of the methods or techniques used for designing industrial processes accompanied with discrete events and also the manner of transforming this technique into LDD or SFC (sequential function chart) through the logic equations. To complete the description of the implementation process, all these procedures are illustrated with a practical project that fulfills the real requirements of the industrial sector.
