In this ABB sponsored project we have extended previous work on parameterised state machine and Petri net models. These models capture control and timing aspects of distributed controllers in hierarchical architectural definitions of software such as IEC6-1131 Function Blocks diagrams. Our work on parameterised contracts and dependent finite state machines has led to an implementation of an analysis package in Java and C#. In a recent integration into the ABB Aspect Integration Platform the package is now being used as a new 'TCAP aspect'. FBs are translated into our underlying semantics on which we analyse their timing properties interactively.In this talk I present underlying concepts, highlight elements of the TCAP system under development, and briefly touch on related work in the Formal Component Software Engineering group in the DSSE Centre at Monash University.
