  1. PROL’s Demonstrator Background and Requirements

  2. Specification of Objs and ISim modules Specification for each railway object • input, output representation • conversion rules Safety task specification Specification for simulator (ISim module)

  3. Questions • Modeling safety architecture (2oo2) • Referring to potential faults (fault database) • Defining parameterizing phase: • how can we model • possible faults of parameterizing

  4. Application environment Behaviour Model of Railway Objects (UML statechart) conversion, extension extension simulator application model Objs application model code generation, interfaceimplementation test case generation test case generation generated simulator code existing Objs code test case by running the simulator

  5. Application environment of Prolan Example considered: part of the state model of the points object Input: external eventse.g. control sigal, sensor data Output: telegramsIEC 60870-5-104 Modelling: capabilities of a finite state machine (FSM) is enough Behaviour model of railway objects (UML statechart) Input: telegrams Output: status words Modelling: same modell can be used(FSM model of objects) Extension Conversion,Extension Simulator application model objs application model (decoder) Test case generation Code generation, Interface Implementation Test case generation • Modelling: FSM extended with time • first telegram starts a timer • next telegrams are filtered within a time period Input: simulated events Output: telegrams Generated simulator code Existing objs code test case by running the simulator

  6. Example: railway object - points
