Question

What is SCADA ? Explain the basic functions
SCADA and describe distributed SCADA system architecture
​

Answer 1

Answer:

Supervisory control and data acquisition (SCADA) is a system of software and hardware elements that allows industrial organizations to: ... Directly interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software.SCADA systems perform several functions. The three basic functions are the monitoring, control and user interface functions. The monitoring function collects data and sends it back to the central computer.In the second generation, the sharing of control functions is distributed across the multiple systems connected to each other using Local Area Network (LAN). Hence, these were termed as distributed SCADA systems.

Answer 2

Supervisory control and data acquisition (SCADA) is a system of software and hardware elements that allows industrial organizations to:

Control industrial processes locally or at remote locations

Monitor, gather, and process real-time data

Directly interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software

Record events into a log file

SCADA systems are crucial for industrial organizations since they help to maintain efficiency, process data for smarter decisions, and communicate system issues to help mitigate downtime.

The basic SCADA architecture begins with programmable logic controllers (PLCs) or remote terminal units (RTUs). PLCs and RTUs are microcomputers that communicate with an array of objects such as factory machines, HMIs, sensors, and end devices, and then route the information from those objects to computers with SCADA software.
