There was a time DC silicon-controlled rectifier (SCR) power motors and DC motors with a permanent magnet field were the main solutions for applications requiring variable-speed performance. Although AC induction motors offered cost savings over their DC cousins, extracting variable-speed performance from an induction motor required either motor/alternator combinations or a mechanical adjustable-speed pulley system. All that changed in the 1980s, when solid-state power electronics enabled the development of a practical AC inverter drive. Advances in power electronics made getting variable-speed performance from an AC motor more practical and cost effective.

SCADA systems include hardware and software components. The hardware gathers and feeds data into a computer that has SCADA software installed. The computer then processes this data and presents it in a timely manner. SCADA also records and logs all events into a file stored on a hard disk or sends them to a printer. SCADA applications warn when conditions become hazardous by sounding alarms.

SCADA (Supervisory Control and Data Acquisition) is a type of industrial control system. In typical industrial automation applications, PLCs are used to communicate between the plant and SCADA. In this paper we are using a low cost microcontroller to understand the various control techniques and capabilities of SCADA and implement them in real time. A simple temperature control scheme is developed using ATMEGA2560 microcontroller and industry standard SCADA software Vijeo Citect v7.2. We make use of MODBUS ASCII protocol which is an industry standard communication protocol to set up a temperature control system which collects real time temperature data, processes the data and performs the desired control action. Major contribution of the paper is in developing MODBUS library for communication between microcontroller and SCADA and implementing control algorithms such as ON/OFF and proportional controller on data obtained in real time. Thus this paper presents a low cost automation scheme which can be easily extended for more complicated control schemes including wireless control. The project has been developed as first step towards a project on pipeline leakage detection scheme using wireless sensor nodes.
