Sequential control using ladder logic, Programmable Logic Controllers (PLCs), and operator interfaces are commonly used in the manufacturing industry today. The introduction course of programmable logic controller is a course that needs a lot of practice. We present a project-based approach to teaching it by introducing real engineering projects into the process of theory teaching. The students show more enthusiastic during learning course and their abilities of solving engineering problems are greatly enhanced.

This paper presents programmable logic controller based elevator control system. Primary focus is on using programmable logic controller to build the elevator model. To control the motion of the elevator through various levels DC geared motor is used. Push buttons are used to give signal to the elevator to come to the desired floor, traversing up and down. Moreover DC relays are used as switches, not protective devices, to drive the motor in clockwise and anticlockwise direction. Ladder logic is used for the model implementation.

 Parking is an integral component of the transport system. It plays a crucial role in the management of traffic and congestion. On-street parking constitutes one major problem that makes traffic situation chaotic in Nigeria cities. Most roads in Nigeria cities are narrow and lack pedestrian lanes. As we all know, vehicles are used extensively for transportation. It is also important to have easy and effective system for maintaining the vehicles cleanliness as well which necessitate this simulation experiment. The simulation experiment involves the use of LADDER SIMULATOR which allows the Programmable Computer to simulate a Programmable Logic Controller such that Ladder Logic PLC programs can be developed in a simple ‘Drag and Drop’ manner. The system entails the use of several proximity sensors and components like Timers (On-Delay), Counters (Count-Up and Count-Down), LEDs to control the process of cars moving in to the car park with the proper arrangement of cars entering the car park and the exit of the cars. The sensors transfer the outputs to the PLC (programmable logic controller). This type of setup is an Advanced Parking System (APS) which acquire information any about available parking spaces, process the information and then present it to drivers by means of variable message signs using LADSIM simulation technique. The problem of car parking space is enormous which made this work relevant due to insufficient parking spaces and lack of skilled security men.  There is a worldwide and global shift towards the automatic car parking system to calculate accurate space available for car and for revenue collection as parking fees. Opinion statistical analysis sample test with KMO and Bartlett's validity test conducted among fifty students revealed a strong positive significant (0.759) in support of the use of automated car parking system in Nigeria. The significant of this new scheme is that it provides an improvement and reliability in the present car parking system and this system can be implemented easily because it is very economical, dependable and cheap. Keywords— Sensors, PLC (programmable logic controller), Car parking; LADSIM; Ladder Logic.

<span>Signal Interpreted Petri Nets (SIPN) modeling has been proposed as an alternative to Ladder Logic Diagram (LLD) modeling for programming complex programmable logic controllers (PLCs) due to its high level of abstraction and functionalities. This paper proposes an algorithm to efficiently convert existing SIPN models to their LLD models equivalences. In order to automate and speed up the conversion process, matrix calculation approach is used. A complex SIPN model was used to show that existing conversion technique must be expanded in order to cater for a more complex SIPN models.</span>
