This SCADA tutorial covers SCADA basics, applications, working of SCADA system etc. The SCADA tutorial also covers various scada system equipment categories and manufacturers.
What is SCADA?
Supervisory Control And Data Acquisition is the full form of SCADA. Remember SCADA is not specific technology but SCADA system vary based on different applications such as electrical, sewage, building, telecom, rail & roadways,energy etc. SCADA protocols depend on these applications as there are different parameters to be managed. Let us examine the same below.
SCADA Applications
SCADA has following major applications of use.
Electric Utilities- Manage Current,voltage,circuit breaker,power grid.
Water and Sewage - Monitor and control water level, water flow and water pipe pressure.
Building - Control heating,ventilation,air conditioning,visualization,lighting and building access systems.
Mass Transit - regulation of electricity, track and locate buses,trams,trains
Railways/Roadways - Control traffic signal lights
Working of SCADA System
Following basic functions are performed by SCADA in general irrespective to applications. Data Acquisition, Data Communication, Data Presentation in various formats, Data Control based on various parameters. All these functions are done by following equipment categories.
SCADA equipment basic categories
Sensors - There are analog and digital type of sensors. With digital type discrete level of monitoring is taken care. With analog type precise measurement of value is performed. There are sensors for temperature,humidity,current,motion, water applications. For data acquision sensors are attached with RTUs to take measurements.
SCADA Remote Telemetry Units(RTUs)- These units are interfaced with sensors as well as with SCADA master using communication network. They provide deliver various parameters to central station(SCADA master) to be managed by them.
SCADA Master - Composed of programmable controls, multiprotocol support and provides human interface. It takes inputs from sensors via RTUs and regulate various applications. Provides various display formats in graphs, tabular and other forms. It will have various LEDs/Alarms for various functions. It also provides email/paging based on certain conditions.
Communication medium/network - These are various interfaces to connect SCADA master with SCADA RTUs.

SCADA stands for supervisory control and data acquisition. It is an industrial control system where a computer system monitoring and controlling a process.
Another term is there, Distributed Control System (DCS). Usually there is a confusion between the concept of these two.
Components of SCADA
1. Human Machine Interface (HMI)
Scada For Dummies
It is an interface which presents process data to a human operator, and through this, the human operator monitors and controls the process.
2. Supervisory (computer) system
It gathers data on the process and sending commands (or control) to the process.
3. Remote Terminal Units (RTUs)
Scada Tutorial Pdf
It connect to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system.
4. Programmable Logic Controller (PLCs)
Scada Pdf Books
It is used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose RTUs. 3d making software free.
5. Communication infrastructure
Scada Basics Tutorial Pdf
It provides connectivity to the supervisory system to the Remote Terminal Units.
