WHAT IS SCADAWHAT IS SCADA

SCADA stands for Supervisory Control And Data Acquisition.

SCADA refers to a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data.

WHAT IS DATA ACQUISITIONWHAT IS DATA ACQUISITION

Data acquisition is the process of retrieving control information from the equipment which is out of order or may lead to some problem or when decisions are need to be taken according to the situation in the equipment. So this acquisition is done by continuous monitoring of the equipment to which it is employed. The data accessed are then forwarded onto a telemetry system ready for transfer to the different sites.

Human-Machine Interface is the apparatus which presents process data to a human operator, and through this, the human operator monitors and controls the process.

Remote Terminal Units connecting to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system.

Programmable Logic Controller used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose RTUs.

FEATURES OF SCADAFEATURES OF SCADA

REAL TIME AND HISTORICAL TRENDREAL TIME AND HISTORICAL TREND

The trend play very important role in the process operation. If your batch fails or the plant trips, you can simply go to the historical trend data and do the analysis. You can have better look of the parameters through the trend..

ALARMSALARMS

have a very critical role in automation. Generally we have alarm states for each inputs/outputs. . Most of the SCADA software support four types of alarms like LOLO,LO,HI and HIHI.

RECIPE MANAGEMENTRECIPE MANAGEMENT

When you have different products to manufacture, you just have to load the recipe of the particular product.

SECURITYSECURITY

BENEFITS OF SCADABENEFITS OF SCADA

Long distance monitoring Long distance training Protection against terrorism/vandalism-alarm Data management (engineering and

operations) Automated operations with real time control

CONCLUSIONCONCLUSION

SCADA is a control system with

● More interfaces and efficient storage

● More record or device oriented configuration

● But system wide configuration tools are needed

● Are less expensive than DCS, but offer different functionality than DCS

● And finally various applications
