What is SCADA and why it is used?

SCADA is a powerful control system that is designed to collect, analyze, and visualize data from industrial equipment. Operators can view critical measurements like temperature, vibration, power usage, and levels across industrial equipment.

How does a SCADA system work?

A SCADA system is a combination of hardware and software enabling the capture of data within, and automation of, industrial processes. SCADA connects the sensors that monitor equipment like motors, pumps, and valves to an onsite or remote server.

How many PLC are there in SCADA?

Supervisory Control and Data Acquisition (or SCADA) is an automated control process that many large industries use for industrial automation, such as manufacturing, construction, and engineering facilities. SCADA is a system made up of two components: PLC (programmable logic control)

What are the four basic parts of a SCADA system?

A SCADA system usually consists of the following main elements:

  • Supervisory computers.
  • Remote terminal units.
  • Programmable logic controllers.
  • Communication infrastructure.
  • Human-machine interface.
  • First generation: “Monolithic”
  • Second generation: “Distributed”
  • Third generation: “Networked”

How can I learn SCADA?

If so, you need to learn about supervisory control and data acquisition (SCADA) and programmable logic controllers (PLCs)….How to Learn SCADA: Step-by-Step

  1. Determine your knowledge gaps.
  2. Start researching.
  3. Study thoroughly.
  4. Enroll in a class.
  5. Enroll in online courses and get certified.


OT is a term developed to differentiate it from IT which represents the information technology assets of an organization. OT is closely related to ICS (industrial control systems) and SCADA (supervisory control and data acquisition systems).

Is SCADA and OT system?

Supervisory Control and Data Acquisition (SCADA) refers to hardware and software systems that allow organizations to control industrial processes, and they also provide a graphical user interface for operators to easily observe the status of a system, receive alarms, and make adjustments to processes under control.
