SCADA systems are generally used when combined with PLCs and other devices and sometimes it is even possible that PLCs become a part of the SCADA system for effective operations. If SCADA and PLCs are used together, they form an automatic system to allot maintenance tasks that form the core of a predictive maintenance program.

With the effectively changing trends in the technical world, the use of IoT in the SCADA system would bring a positive change with its advanced capabilities of drawing more attention towards productivity. It is one of the great advancements in history that machines are now able to take care of themselves through technology. Even an effective report generation through IoT plays a huge role in providing better decision-making and suggesting strategies to improve business performance like never before.
