Research overview:
Function block(FB) defined in IEC-PAS 61499-1, will provide us a method to construct IPMCS(Industrial Process Measurement and Control Systems) based on OOD(Object Oriented Design). The interfaces of FBs are specified in a common way, the interface declaration of FB can be separated from its implementation and its represented by the abstract classes or interfaces in OOD. Delegation event model can be applied to representing the event flows of the function blocks. We regard also the data flow as a particular kind of event flow, and the same event model is also applied to it. Since we can use easily the event delegation model in JavaTM, JavaTM is suitable for describing function blocks. We propose an implementation of function blocks using JavaTM in this research and development.
