Method, system and computer program product for simulating a production automation system with service-oriented architecture

摘要

The invention relates to methods and a system for simulating a production automation system with service-oriented architecture, wherein components of the production automation system through service-oriented device models (CON, MA, LE, GA) in a service-oriented Simulation environment can be represented, wherein functions and / or properties of the device models (CON, MA, LE, GA) as function and / or property services (P, E) offered and / or called via a SoA communication network (N) and wherein a simulation of the production automation system is carried out on the basis of a chronological sequence of the calls of the function and / or property services (P, E). In order to realize a discrete-event simulation, it is provided that the service-oriented device models (CON, MA, LE, GA) during the execution of the simulation in response to a call of an offered function and / or property service (P, E ) call a simulation service (SE) offered by a simulation manager (SIMM) that a new discrete simulation event (DSE1 ... DSEn) is generated by each call of the simulation service (SE), which information in each case via an event time, an event type and the calling device model (CON; MA; LE; GA) contains the discrete simulation events (DSE1 ... DSEn) in chronological order in accordance with the event time Simulation Manager (SIMM) database (ED), that the simulation is executed as a discrete-event simulation by executing the stored discrete simulation events (DSE1 ... DSEn) in chronological order and that at Au The Simulation Manager (SIMM) calls up a simulation service (TE) in the corresponding device model (CON, MA, LE, GA) for the discrete simulation events (DSE1 ... DSEn).
