A Study of Programmable Logic Controllers (PLC) in Control Systems for Effective Learning

PLC controllers in today's day are a staple mechanism to control operation of large number of machines and devices in the industry. With their advanced usage, it is increasingly becoming a staple and important part of Engineering. Thus, it is crucial that this knowledge is effectively delivered to students with practical applications. This paper presents a series of laboratory experiments for students to learn and explore the various industrial applications of PLC’s. The control problems in this paper are defined with respect to their applications in different industries such as automotive, steel, oil and electronics. Applications are typical processes that can be observed in these industries such as material conveying, material handling, cutting processes, system control and temperature control. All the problems are solved using Ladder Logic programming on Automation Studio to simulate these processes and provide students with a wholesome learning experience.

Four Junction Traffic Light Controller using PLC (S7-200)

Advance of a road traffic light control system using Programmable Logic Controller is the principal of the system. This system can be divided into two parts which are hardware and software. The hardware part for this system is a model of four -way junction of a traffic light. The Red, Yellow and Green are installed at each lane to represent as a traffic light signal indicator. This switches and lamps are linked to PLC. The PLC receives signal which is coming from the inputs (sensor and switch) and drives the units (lamps or relays). In the system, Siemens s7-200 PLC is used as the main controller of the traffic light system. The Step7 Micro Win software can be developed the ladder logic diagram which can control the traffic light for proposed system. So, the traffic light system can be successfully controlled by PLC.
