Abstract
As a result of technological developments, remote control via communication techniques such as ZigBee, RF, Infrared, Wi-Fi and mobile communication techniques has been widely used in various fields. These techniques have both advantages and disadvantages. GPRS (General Packet Radio Service) communication offers a non-stop, secure and cheap communication to individuals where there is no access to Internet. This study consists of PLC-based, online monitoring and control of the parameters of a widely-used induction motor utilizing the GPRS/GSM (Global System for Mobile Communications) communication technique. The research monitored current values of three phases drawn from the network, voltage values of three phases applied to the induction motor, power factor, rpm (rotation per minute) and operating frequency. The induction motor was operated by keeping the V/f ratio constant via a frequency convertor; a visual user interface was prepared on the Profi-Lab Expert platform, and then presented to the users through the Profi-Lab Web Server program.

Highlights
Technological developments have enabled to be taken classic systems’ place by automatic and advanced systems
The present study reports on monitoring and vector control of the parameters of an induction motor using GPRS communication technology
The parameters of the induction motor were thereby read through the boards designed via programmable logic controllers (PLC) and they were monitored via GPRS/GSM using the web interface developed on OPC Server
Summary
Technological developments have enabled to be taken classic systems’ place by automatic and advanced systems. It was found that products with different technologies and characteristics such as microcontrollers, data acquisition boards (DAQ), programmable logic controllers (PLC) and FPGA (Field Programmable Gate Array) were preferred [2]–[5]. Different control technologies are used for monitoring and control of the systems, whereas the communication between a system and a user is generally realized online via wireless communication techniques such as Rf, ZigBee, Bluetooth and GPRS in remote monitoring [14]–[17]. Through different communication methods, monitoring and control are realized via remote-controlled technological communication techniques such as Profi-Bus and GPRS [18], [19]. The web-based user interface for remote control and monitoring was developed via the Profi-Lab Expert program and it was presented online to users via the Profi-Lab WebServer program. Visually and resiliently in comparison with other programs, as Profi-Lab Expert program has a rich library of predefined functions that enables developers to create a user interface without the need to write code
