The instruction of industrial controls employing programmable logic controllers (PLCs) is vital for many industries including manufacturing, mining, and production. PLCs are self-contained industrial grade microcontrollers with user-friendly input and output buffering. They are typically programmed using a visual ladder logic based language. In response to requests from our constituents, we implemented an industrial control course based on both PLC and microcontroller technology. In developing the course, a graduate student worked closely with an industrial control company to develop a series of practical, hands on laboratory exercises to educate students on the fundamentals of PLC application design and implementation. In conjunction with development of laboratory courseware, an Industrial Control Laboratory was developed and equipped with state-of-theart PLC and control instrumentation and test equipment. This paper discusses the development and content of the laboratory exercises and physical laboratory. We have now taught this course twice and have gathered student perceptions on the quality and utility of the Industrial Control course. Students have requested additional emphasis in this area. We conclude the paper with plans for future course enhancements.

Abstract The proposed methodology enables to secure the control program of automated production systems. The principle is to place a robust filter inside the PLC of the automated production system to inhibit or authorize actions in the event of detection of errors in the control program. The proposed methodology rests on the one hand, on a rigorous analysis of the automated production system in order to formally build the set of constraints which constitute the filter using temporal and boolean logic. And on the other hand, a phase of modeling by finite-state automata which is necessary to validate the sufficiency of the constraints and to check the robustness of the filter as well as the safety properties using Model-Checking tools.

Abstract In this paper an approach that utilizes the paradigm of agent-orientation for the software development of automation systems, is presented. We discuss different methods for agent-oriented software development in general and motivate a novel approach that meets the special requirements for control software in production automation. We show how this novel approach can enhance the dependability of control software by integrating concepts for diagnosis and failure compensation in real-time. Furthermore, we present a modelling approach, that will be integrated into a market leading IEC 61131 software development tool and by that, allow application engineers to implement agent control software.
