AutomationML aims to close this gap by supporting the exchange of a variety of aspects of automation engineering and its ability to manage multiple semantics in a heterogeneous engineering tool landscape. But beside all AutomationML-concepts, the introduction in the industry is bound to its ease of use. This paper gives an overview about the results of an activity of the AutomationML society which investigated concepts to reduce the AutomationML programming effort. After an introduction into basic requirements, this paper proposes a generic design for im-and exporter software and explains how to technically manage semantic variety. In addition, the author gives an overview about typical errors in AutomationML object modeling and how to avoid them. Finally, this paper wraps up with a major prejudice about XML based file exchange, the lack of performance, and presents encouraging results of a CAEX performance investigation.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131215499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This information is required for analyses of effects due to temporal changes of the physical system structures, e.g. to analyze the effect of a component fault onto the automation system functions. This contribution proposes a metamodel for the system level design of automation systems, which makes use of hierarchical structures offered by the description language AutomationML, structured on the basis of the IEC 81346 aspects: product, function, and location, and supplemented by inter and intra structure relationships for modeling the dependencies. Modeling temporal changes is considered by means of the integration of an event structure into the metamodel.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128023676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This flexibility is mainly realized by software. Standards like IEC 61508 for functional safety demand intensive testing efforts to ensure a certain level of integrity. The uncertainty about system behavior, especially in fault situations, complicates reliability testing. We propose a concept that integrates fault models into SysML system models for model based development. The introduced fault models can be designed in two granularity levels, starting with coarse information at early development phases up to precise mathematical relations. The concept is applied to a component (rotary switch) of a laboratory plant, which connects three conveyor bands where friction deviation can occur during rotary movement. Such models can build the foundation for test generation in reliability testing.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133738789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A tuning rule for the reset ratio parameter of the PI+CI compensator is proposed in order to improve the disturbance rejection.

This concerns any level of the system from the configuration and control to the management of production. The proposed work deals with the development of an innovative platform jointly managing the production scheduling level and the automation level. The major advantage coming from the platform is the capacity of generating scheduling plans which are executed at automation level and concurrently monitored over time so that any production anomaly or system misbehavior can be dynamically interpreted and adapted by regenerating online a new schedule. The paper describes the current release of our closed loop architecture that integrated both control and automation parts.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the productivity and cost of the system are also determined. The approach of the Assisted Engineering aims to integrate experience and knowledge of existing manufacturing systems in the engineering process. For this purpose, these systems are modularized and systematically integrated into a knowledge base. This knowledge base allows a more efficient engineering process by reusing mechatronic modules. Thereby, the performance of a manufacturing system can be substantiated at an early stage of engineering. The approach described in this paper aims at increasing the reusability of such modules. For this, the modularization of existing systems is optimized so that the modules are not too specific for reuse in the development of a new manufacturing system.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"50 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123698631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both the plant and controller models are described in a formalism where urgent transitions are possible, to avoid non-realistic evolutions, and without deadlock when they are separated. It is first shown that deadlocks may occur in the plant model as soon as both models are coupled. To solve this issue, shared variables which model the changes of the inputs of the controller are defined and introduced in some actions of the plant model as well as in some guards of the controller model; the aim of these variables is to authorize evolutions of the controller only when at least one input has changed. This solution removes the previously pinpointed deadlocks and guarantees the reactivity of the controller.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122896066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
