- SCADA systems are very important for industrial organizations because they help maintain efficiency, process data for smarter decisions and communicate system problems to help minimize downtime.
- Basic SCADA architecture begins with programmable logic controllers (PLCs) or remote terminals (RTUs). PLCs and RTUs are computers that communicate with a variety of objects such as factory machines, HMIs, sensors and terminals, then route information from those objects to computers with SCADA software. SCADA software processes, distributes and displays data, helps operators and other employees analyze data and make important decisions.
- For example, the SCADA system quickly informs an operator that a batch of products is displaying a high error rate. Moderators stop working and see SCADA system data via HMI to determine the cause of the problem. They looked at the data and found that Machine 4 was broken. SCADA system to notify the incident operator to help him solve the problem and prevent further loss of products.
