• Acronym stands for u#erisory Control and !ata Ac=uisition
•  <ot a full control system, but rather focuses on the su#erisory
leel
• urely soft'are #ac)age that is #ositioned on to# of hard'are
• Combination of telemetry and data ac=uisition to 'hich it is
interfaced, generally ia -Cs5 or !C5
• Collecting of the information, transferring it bac) to the central site,
carrying out any necessary analysis and control and then dis#laying
that information on a number of o#erator screens or dis#lays control
actions are then coneyed bac) to the #rocess.

Introduction to SCADA:
CA!A systems are designed to collect field information, transfer it to a central
com#uter facility, and dis#lay the information to the o#erator gra#hically or
te>tually, thereby allo'ing the o#erator to monitor or control an entire system
from a central location in real time.

All together, the term CA!A refers to the entire central system. he central
system usually monitors data from arious sensors that are either in close
 #ro>imity or off site.

:biously, a CA!A systemBs initial cost has to be ustified. A fe'
ty#ical reasons for im#lementing a CA!A system are;
• Im#roed o#eration of the #lant or #rocess resulting in
saings due to o#timiDation of the system
• Increased #roductiity of the #ersonnel
• Im#roed safety of the system due to better information and
im#roed control
• Im#roed energy saings due to o#timiDation of the #lant
• Im#roed and =uic)er recei#t of data so that clients can be
inoiced more =uic)ly and accurately
