description: In this short paper we describe early work on a case study concerning a power window control unit. We use UML-B state machines to simultaneously model both the cyclic processing schedule and the mode of control behaviour. We find this a useful way to visualise the model, particularly when the state machines are animated via the Pro-B animator. We verify the state machines using the Event-B proof tools. We envisage new developments to the UML-B tool set to improve support for this modelling technique. The motivation for this simple but powerful form of modelling is the immediate benefit and low cost of entry making industrial adoption of formal models more attractive to industry.
