Stiff competition, higher quality standards and growing concerns of safety & environmental damage have pushed the Industrial sector to adapt state-of-the-art Automation Techniques for effective utilization of resources and optimized performance of the process plants. Automation applications span plant automation, discrete and batch process control, embedded machine control and manufacturing production line automation. Operational Technology (OT) refers to computing systems that are used to manage these industrial operations. Recent trends of integrating Information Technology (IT) & OT and merging of control systems associated with both factory and process automation demands knowledge from diverse fields. The industrial automation applications include automation of time critical systems that demand precise real time readings and control. Qualified automation engineers are needed to meet these requirements of designing appropriate automation systems. But, one need to have knowledge of diversified fields such as PC/ PLC based Control, Instrumentation, H/W, S/W, Networking, Industrial AC Drives, Machine Vision, DCS, SCADA/HMI, Industrial IoT (IIoT), High speed data acquisition, cRIO etc., to become a successful automation engineer.
