What is a SCADA?

SCADA is an acronym that stands for Supervisory Control and Data Acquisition. Basically, a SCADA system performs two actions, data acquisition and control. SCADA collects data from field device and controllers in the field and sends this data to the main central control unit and which then manages and controls the data.

SCADA systems are used mainly in the industry for control of supervision and data acquisition of industrial processes. A SCADA system can control other controllers such as PLCs, DCSs located at distant locations as a monitoring system. Therefore, SCADA is used in large industries.

What is SCADA software?

A SCADA software is used to acquire data from field devices, monitor the data and use it to control the hardware. It is used in power plants, oil and gas refining, telecommunications, transportation and water and waste control.

The software constantly searces for plant data in real time, stores data in the database, processes them in the database, generates reports, evaluates and generates alarms, displays information on display plant operators to plant operators, supervisors and managers

How to choose a SCADA software?

  • Is your SCADA system compatible across multiple operating systems?

  • Will it support my future needs as well as my existing ones?

  • What drivers does the SCADA system include?

  • What’s the cost?

  • How is the customer support?

  • Is it Scalable?

  • How easy will it be to upgrade my system?

  • How safe is my SCADA system?

Purpose of SCADA software

  • Monitoring: Continuous monitoring of parameter and variables

  • Data Acquisition: Frequent acquisition of data from RTUs and Data Loggers

  • Control: Online real-time control for closed loop and open loop processes.

  • Measurement: To gather measurement information and measurement variable processing

  • Automation: Automatic tasks of switching of transmission lines, CBs, etc
