Most important, transmitted data have to be secured using cryptographic techniques. However, even if the used cryptographic algorithms are perfectly secure, the overall security highly depends on the non-disclosure of the used shared secrets. Therefore, this paper targets the management of these shared secrets and the necessary infrastructure used to manage them. Finally, to eliminate a single point of failure in this infrastructure, a redundancy concept featuring multiple key servers is presented.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"39 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":"127275770","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}

On the other hand, there is the approach of providing data with individual frames for each node. The two most relevant factors influencing the performance in terms of the minimum achievable update time are the propagation delay and the frame transfer time. In this paper we introduce a new concept for reducing the minimum possible update time for individual frame based systems like PROFINET IRT. The performance evaluation compares the results of our concept with the summation frame based EtherCAT System.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"184 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":"123270844","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}

However, existing agent platforms do not always fulfill the requirements of practical automation applications in respect to real time properties and resource usage. Often, they offer a lot of functionality that is not necessary in automation and leads to significant overhead in respect of design effort and runtime resources. To meet the specific requirements of the automation domain, the resource-efficient agent platform AMES was developed, which relies on established concepts of agent platforms, but modifies and supplements them accordingly. The AMES platform is implemented in Java and in several C++ variants. This paper describes the architecture of the AMES platform and discusses several performance issues. Results of various performance tests are presented in comparison to the established agent platform JADE.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"5 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":"114233911","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}

In this work, we replay an a-priori defined bus traffic to influence the clock synchronization mechanism. Beyond testing this distributed mechanism itself, our aim is to draw conclusions on the nodespsila bus receiver operation. Since these replay activities are part of a transparent online test procedure, it is important to ensure that they do not represent a threat for proper system operation. We present a respective formal proof for TTP/C, while for the case of FlexRay we show that the system precision can be bounded according to the replay operation applied. Experimental results confirm and illustrate our approach.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"13 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":"132459646","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 Open-EDD technology was developed base on software standards already spread for personal computers (XLST, Xerces - DOM implementation, OO, XML Schema) and it is applied in this paper as viable alternative to the currently standardized Device Description technology (IEC 61804-2 - EDD) used for the HART, PROFIBUS and FOUNDATION Fieldbus protocols. In the case of FOUNDATION Fieldbus protocol, for the integration of IEC 61804-2 EDD with FBSIMU, it is necessary to purchase an integration toolkit, that has a high cost. The fieldbus simulation is based on the FBSIMU tool that focuses on the application process of Foundation Fieldbus systems and provides all functionalities to the user considering the configuration and operation of a fieldbus strategy. The results comprehend a functional and temporal evaluation that proves the possibility to reach fieldbus interoperability with the use of truly open software standards.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"201 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":"124398093","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}

Many wireless technologies are available today, where most important are IEEE 802.11 a/b/g for WLAN, and IEEE 802.15 for WPAN standards. Despite the advantages a single wireless technology might offer in an automation system, it will be often required to run multiple WLAN/WPAN networks in parallel in different or overlapping regions of the plant. Most of these technologies are working in the 2.4 GHz ISM band which is unlicensed and available all over the world. Because of this fact, it can be expected that all these technologies will interfere with each other. Thus the coexistence of multiple networks needs to be investigated and some parameters should be adjusted to optimize reliability and security of these technologies. We suggest an easy-to-use coexistence measurement test site and investigated the coexistence properties of WPAN systems like Bluetooth IEEE 802.15.1, ZigBee IEEE 802.15.4, IEEE 802.15.4a based CSS, and narrowband FSK and suggest optimal parameter settings.","PeriodicalId":352963,"journal":{"name":"2008 IEEE International Workshop on Factory Communication Systems","volume":"29 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":"124033504","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}
