Existing monitoring and control of an induction motor systems must be interoperable with next generation products to ensure smart integration in order to update existing system by reducing the cost and increasing the reliability. The best method must be chosen for efficient use of energy in some cases such as speed control, switching-on or switching-off, or in controlling the speed of induction motors, which make up a large part of the load group in industrial field. In this study, the controlling and monitoring of an induction motor parameters were carried out over a computer by using the Profibus (Process Field Bus) communication method through the TIA (Totally Integrated Automation) Portal program used to program all Siemens PLCs (Programmable Logic Controllers). The induction motor parameters were obtained over the frequency converter without using additional cards such as current, voltage, frequency and speed measurement. In this way, cables and electronic cards confusion were avoided and a safer, faster and more functional application was implemented compared to classical methods. KEPServerEx OPC (Ole-for Processing Control) Server program by OPC Foundation was preferred for the communication of computer with a PLC. Profi-Lab editor program was used for monitoring and controlling the system over a computer.
