To overcome some of them, we proposed a replicated star topology, ReCANcentrate, whose hubs incorporate fault-treatment and fault tolerance mechanisms. The two hubs of ReCANcentrate are coupled with each other, thereby forcing a single communication domain that simplifies the management of the replicated media that each node performs to ensure data consistency. This paper proposes additional mechanisms to enforce data consistency even when hubs become temporarily or permanently decoupled.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121603313","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}

Therefore, static structures, close coupling and vendor-specific solutions have been established over decades. To increase flexibility and interoperability we introduce a service-oriented middleware approach in form of an integration layer between shop-floor equipment and enterprise applications. The integration layer addresses the actual capabilities and data flows on the field and control layer individually. It offers core services that are applicable in several manufacturing domains. We describe a detailed case study to discuss pros and cons of a SOA approach in manufacturing systems and to show the feasibility of our approach.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"28 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113959481","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}

Although there exists a various class of applications, like synchronizing the clock of a PC with the network time protocol, where an accuracy of several milliseconds is sufficient, many applications, such as synchronized test and measurement or localization services in wireless LANs require a higher confidentiality in the time domain. This paper enlights some of the key restrictions and possibilities in the case of IEEE 802.3 Ethernet. As this case not only challenges the state of the art oscillator models, but also timestamping techniques, a novel, highly accurate approach for that is proposed. Moreover, a highly accurate deterministic approach also concerns the behavior of the physical layer devices and their influence on the asymmetry, as well as the underlying control loops an analysis of the behavior of both is given together with some preliminary results for Ethernet based clock synchronization in the nanosecond range.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"90 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114095885","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}

Integration, reuse, flexibility and optimization are demanded to adapt to a rapidly changing and competitive market. In fact, standardization is a key goal to achieve these goals. The international standardization efforts have lead to the definition of the IEC 61131 standard. Part 3 of this standard defines a software model for defining automation projects as well as 5 programming languages. Nowadays, a major part of Programmable Logic Controllers (PLC) vendors follows this standard, although each programming tool adds particularities and stores the automation project in different manner. But, although they may use the same software model and the same programming languages, source code reuse is not available. This work presents an infrastructure that allows transferring source code from one PLC programming tool to any other transparently to the users. The proposal consists of a textual expression of the software model and the programming languages, as well as the mechanisms, based on XML technologies, to achieve tool interoperability.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124090890","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}

The latter is supported by maintenance systems that require a tedious configuration process. Therefore, this paper introduces the planning of maintenance activities during the planning phases of a plant, but also an export of data from CAE-Systems to maintenance related systems as well as retrieval of engineering information on-site directly from the engineering databases.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133277386","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}

The semantic device descriptions are based on semantic Web technologies, especially OWL. Several application scenarios are shown, which demonstrate the potential of the introduced approach.
