SCADA (Supervisory Control and Data Acquisition) is a system that allows industrial processes to be monitored and controlled remotely. It consists of data acquisition and process control features. SCADA systems communicate with field instruments using various protocols and can control processes from a distance. They provide benefits like remote monitoring and control, data logging, alarms, and process visualization. SCADA systems connect to controllers like PLCs that are connected to field instruments to monitor and control industrial processes.

20. COST ANALYSISCOST ANALYSIS
• Cost of SCADA is decided by two factors.
Number of tags and packages.
• Packages are DRN and RN
• DRN stands for development ,runtime &
networking.
• RN stands for run and networking.
