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
Scada For Dummies Pdf
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.
