PROGRAMMABLE LOGIC CONTROLLER TRAINING STANDS FOR EDUCATIONAL PURPOSES

Abstract

Urgency of the research. Programmable logic controller are devices for controlling of various systems also in industry. If controlled device is complicated, it is problem to debug application, because of risk of its damage. For this purpose is better to use hardware training stand for testing of your designed application. Target setting. Training stand is as compact small device which is easy to move to another place. Also it allows to connect other hardware device for testing. Logical state hardware simulator is also designed for simulation of logic system with any user inputs with buttons or switches and also witch coloured lights for visualisation of output state.Actual scientific researches and issues analysis. Training set allows to make simulation of control system with real parts before its practical use with expensive controlled system, where any mistake can cause a huge economist loses, but errors occurred during the simulation on training set only make warning and shows the weak place on design. Uninvestigated parts of general matters defining. The questions of the networked structure of programmable logic controller structures are uninvestigated, so the next research will be focused to this. The research objective. The main goal is to create a compact device for training future application developers with a programmable logic controller, but it is also usable for developers from practice, who need to debug the program before installing it into real operation. The statement of basic materials. Existing training sets are large and expensive devices that are not easy to carry and cannot be expanded. Working with such devices is quite complicated. The designed training stand is a flexible and easily portable device. Conclusions. Main contribution is that students will gain practical experiences and skills that are essential for PLC programmers. This device supports also own creativity of students, because it allows to modify hardware composition. It uses the DIN rail system similar as in real installation cabinet. The stand also includes the human-machine interface for training of practical using of these devices.
