The modular production system (MPS): An alternate approach for control technology in design and technology

Traditionally, programming languages which are commonly employed in school control technology are QBASIC and CFA. They have been designed based on definable procedural types. Such languages are generally easy to learn and understand, and are well suited to the requirements of small systems. However, as the complexity of systems has increased, so the limitations of the procedural approach have become increasingly apparent. In order to solve the problem, a language which meets the IEC 1131-3 standard has to be employed. With the aid of a well-defined programming language, more realistic-like applications and problems can be simulated and resolved. This paper introduces an alternate approach in teaching and learning school control technology. The rationale for employing a Statement List, which is a programming language which meets the IEC 1131-1 standard, is firstly discussed. Secondly, the feature of Modular Production System, which is a simulation to real-life industrial production system, is introduced. Thirdly, the design of a processing station using the MPS approach is described. Finally, concluding remarks on the pros and cons of applying the approach are presented.
