ABSTRACT

Using the knowledge we learned in the classroom, making a two story model elevator using Programmable Logic

Controller. To make this project into a reality, we need to do the necessary research as well as seeking advice and insight

from our professors who are very experienced in their respective discipline. Making a two story model elevator is

beneficial for our senior project because it is a good balance of electrical and mechanical engineering. Mechanical

engineers can use their knowledge to design the elevator to its necessary specifications and make a pulley system so the

elevator can move up and down, as well as opening and closing the door. The electrical engineers can program the

elevator using the plc language called ladder logic to make sure the elevator runs properly.

Motivation

The motivation is to use a PLC to demonstrate

how an elevator operates. By using the PLC we

see the detailed work that is design for each

elevator to function.
