TO optimaze human effort & interferance ,,, after the relays something more frequent and optimised was needed,engineer's developed PLC'S .using which we can automize the machinery with a much bettor output an improved rate. SCADA was developed to look on for what all is developed & to control the whole project even in remote mode. AUTOMATIC CAR PARKING SYSTEM. with the advent of plc's it becomes really very easy to control even a jammed place like a parking block, ladder programming is done over a plc,,wherin a proximity sensor is used at the entrance and exit the elevator mechanism is controlled by scada the software used for the whole projet is RS LOGIX 500.
PLC is the soul of automation in industry.
to add any program a user is provided a software -RS LOGIX 500 .
SCADA-supervisory control and data acquistion system as the name signifies ,it provides control and is also used for data acquistion in the industry.it acts as a Remote terminal unit.
Thus helps in controlling the plant from some other location .
this system of plc & sacda system came as a replacemnt to sequintial realy circuts.
INDustrial automation clearly therfore signifies what to really do.it's the minimum HMI technique -human machine interference.It made controlling the machinery very easy and the output/s much compatiable and reliable
we can develop a system less introduced to human's and getting the best out of a system.
