What is SCADA & how does it work ?

SCADA stands for supervisory control and information acquisition. it’s a kind of software system application for process management.

This could be a central system that includes controller’s network interfaces, input/output, communication equipment and software system.
This systems are wont to monitor and control the equipment within the industrial process that embodies producing, production, development and fabrication.

The infrastructural processes embody gas and oil distribution, electric power, water distribution. Public utilities embody bus traffic system, airport.

The SCADA system takes the reading of the meters and checks the standing of sensors in regular interval so it needs lowest interference of human.
Generally this system could be a centralized system that monitors and controls entire space. It’s purely software system package that’s positioned on prime of hardware. A supervisory system gathers information on the process and sends the commands control to the process.

The SCADA could be a remote station unit that is additionally called RTU. Most control actions are auto performed by RTUs or PLCs. The RTUs include programmable logic device which might be set to specific demand. For instance, in the thermal power station the water flow will be set to specific value or it will be modified according to the need.
