SCADA

Supervisory Control and Data Acquisition

SCADA stands for Supervisory Control and Data Acquisition. It's a system that helps monitor and control various equipment or processes from a central location.

Think of it like a remote control for a big factory. It allows people to:

1. See what's happening: Check on the status of machines, temperature, pressure, and other important factors.
2. Make changes: Adjust settings, turn things on or off, or even stop processes if necessary.
3. Collect data: Gather information over time to analyze and improve operations. SCADA systems are commonly used in industries like manufacturing, energy, water treatment, and transportation.

These are the samples of Human Machine Interface HMI for Controlling Devices:

The application of the system depends on your systems, it might applied on substation automation for power distribution or applied on a productional machine of a product. 

It might seems too general if you heard about SCADA Systems, and that makes us confuse what is the real SCADA means. But, look when you are working on electrical systems then you will understand by looking the real application of the SCADA systems. 

So, generally all of the data from remote or the apparatus will be monitored within a Human Machine Interface that will help operator to monitor the system. Then the risk of system disturbance will reduced by knowing what is really happening within the systems. 

The other way, we an also use the SCADA to Control our machine/ or a systems by sending command via protocol that have been integrated between a PLC and the Human Machine Interface on the SCADA. 

I see often when working on the Power Generation System, when the systems seems useful to monitor all of the condition of the Power Plant. Like the supply for motor who deliver power to operate a conveyor for filling coal, and the conveyor condition itself.
