Method for orchestrating services of a service-oriented automation system and orchestration machine
A method for orchestrating services of a service-oriented automation system (SOAS), system components (SMC, LCC) offering services (S, WS) that represent the functionality thereof and requesting services (S) of other system components (SMC, LCC), the behavior of the automation system (SOAS) being controlled by the orchestration of the services (S) of the system components (SMC, LCC) using an orchestration machine (OE), and to an orchestration machine for orchestrating services of a service-oriented automation system (SOAS). In order to achieve an orchestration of services at a device level, it is provided that the orchestration machine (OE) uses high-level Petri nets tailored to service-oriented systems and the orchestration of the services (S) at the device level is performed by interpretation and execution of various HLPN models, which represent the behavior of the automation system (SOAS) and/or the system components (SMC, LCC).
1. Method for orchestration of services of a service-oriented automation system, with system components offering services depicting their functionality and querying services of other system components, with the behavior of the automation system being controlled through orchestration of the services of the system components using an orchestration machine,
characterized in that the orchestration machine is modular and is implemented respectively in the system components as a High-Level-Petri-Net interpreter, or as an auto-run-capable High-Level-Petri-Net control module, and uses High-Level-Petri-Nets tailored to service-oriented systems, and that the services are orchestrated at a device level by coordination and aggregation of the services from the system components by the High-Level-Petri-Net interpreter or the auto-run-capable High-Level-Petri-Net control module by interpretation and execution of High-Level-Petri-Net models depicting the behavior of the system components.
2. Method according to claim 1 , characterized in that the orchestration machine is integrated into a computing unit of the system components.
3. Method according to claim 1 , characterized in that the High-Level-Petri-Nets are described via extended markup language.
4. Method for orchestration of services of a service-oriented automation system, with system components offering services depicting their functionality and querying services of other system components, with the behavior of the automation system being controlled through orchestration of the services of the system components using an orchestration machine,
wherein the orchestration machine is modular and is implemented respectively in the system components as a High-Level-Petri-Net interpreter, or as an auto-run-capable High-Level-Petri-Net control module, and uses High-Level-Petri-Nets tailored to service-oriented systems, and that the services are orchestrated at a device level by coordination and aggregation of the services from the system components by the High-Level-Petri-Net interpreter or the auto-run-capable High-Level-Petri-Net control module by interpretation and execution of High-Level-Petri-Net models depicting the behavior of the system components, and
characterized in that linked to interpretation or compilation, High-Level-Petri-Net description is converted into data structures in the form of matrices.
