USE OF PROGRAMMABLE LOGIC CONTROL IN MODERN VEHICLE
INTRODUCTION.
01. Programmable logic controllers (PLCs) have become the most predominant control elements for the discrete event control of a mechatronics system. Simplification of engineering and precise control of mechanical or manufacturing process can result in significant cost savings. The most effective way which can pay big dividends in the long run is flexible automation; a planned approach towards integrated control systems. It requires a conscious effort on the part of engineers to identify areas where automation can result in better in orders to save man-hours or down time. Controls automation need not necessarily be high ended and extremely sophisticated; it is the phased, step-by-step effort to automate, employing control systems tailored to one’s specific requirements that achieves the most attractive results. This is where programmable logic controls have been a breakthrough in the field of automation and control techniques.
02. The basic idea behind these programmable controllers was to provide meansto eliminate high cost associated with inflexible, conventional relay controlled systems.Programmable controllers offer a system with computer flexibility that is suited towithstand the harsh working environment, has simplicity of operation/readability, canreduce machine down time and provide expandability for future and is able to bemaintained by average technicians.
03. In an automated system, the PLC is commonly regarded as the heart of the control system. With a control application program that is stored in the memory of the PLC, it constantly monitors the state of the system through the field input devices’ feedback signal. It will then based on the program logic, determine the course of action to be carried out at the field output devices.
