Effect of PLC and SCADA in boosting the working of elevator system

Elevators are used as main connectivity unit of the floors, in malls, offices, industries and, buildings of the hospital. Generally, the chip based controllers are used to control the working of the elevator system. These controllers have some sharp specifications which cannot be maintained at all the time and, that´s why faults occur from time to time. So, Programmable Logic Controller (PLC) is implemented in place of embedded system. PLC can easily withstand the faulty situation occurred in industrial environment and easily maintain all the specific requirement of the elevator system. In the present work, the ladder programming is used for PLC. It has very simple and handy programming, i.e., if we want to increase, decrease or skip any floor then program can change as per our requirements. Supervisory Control and Data Acquisition (SCADA) is also used to supervise and control the working of the elevator. If somehow any fault occurs then SCADA itself identifies the fault position and generates an alarm. The response on the fault can be taken within no time by interfacing PLC and SCADA with the elevator system.
