Which of the following is NOT a function of SCADA systems?

SCADA (Supervisory Control and Data Acquisition) systems are primarily designed to monitor and control infrastructure processes, such as those found in pipelines, water treatment facilities, and electrical grids. One of the key characteristics of SCADA systems is their ability to collect and log data, allowing operators to analyze system performance over time. They also monitor the status of equipment, providing real-time insights into operational conditions, which helps in decision-making.

Another essential function of SCADA systems is controlling equipment operations. This includes remotely starting or stopping pumps, valves, and other critical components of the infrastructure, ensuring that everything operates smoothly and efficiently.

On the other hand, providing emergency medical services is outside the primary scope of SCADA systems. While these systems may provide critical operational data that can indirectly support emergency response efforts, they do not directly manage or deliver medical services. This distinctly identifies it as an activity that is not a function of SCADA systems, which is why this choice is the correct answer in this context.
