Architectural Concepts for IEC 61499-based Machine Controls: Beyond Normal Operation Handling

Modern production systems are constantly getting more complex and moving towards smaller lot sizes and more customizable products. This poses new challenges on the control software, which is growing in size and complexity. To deal with this increasingly large and complex control software, design guidelines are needed. We are working on such design guidelines for IEC 61499, a modeling language for distributed control systems. In our previous work, we proposed a distributed and highly reusable application design based on skills. In this work, we will present concepts for extending this design beyond normal operation handling.
