This has driven the need to have time synchronization at all levels of the enterprise. Time synchronization protocols such as network time protocol (NTP) and precision time protocol (PTP) have been defined for performing synchronization over distributed systems. Lack of time synchronization among the various subsystems is seen as a factor of poor data quality in equipment data acquisition (EDA) and advanced process control (A PC) analysis. The focus of our study is to investigate the extent and precision of time synchronization that can be practically applied with the available protocols at various levels of the semiconductor factory environment to meet next generation manufacturing requirements. To this end, we describe the objectives, details, and implementation of the simulator that aims to model a semiconductor factory network This will provide a practical perspective to study the accuracy achievable and potential network factors contributing to accuracy degradation of factory-wide time synchronization.","PeriodicalId":258197,"journal":{"name":"2007 IEEE International Symposium on Precision Clock Synchronization for Measurement, Control and Communication","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115261280","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 effects of these environmental conditions on the stability of the frequency of clock sources are well studied [1, 2]. However the influence on the synchronization characteristics of IEEE 1588 can be derived only partly from these investigations. The dependency between the frequency drift (df/dt) and the transmission period of the synchronization frames T is very important for the achievable accuracy of IEEE 1588-based networks. In order to examine these effects, a novel measuring method is proposed in this paper. The results of exemplary measurements at a crystal oscillator with different temperature and mechanical loads will be discussed. These results are compared with the existing requirements for industrial communication systems, especially for the Industrial Ethernet system PROFINET. The objective is to derive coherences and rules for the implementation of functional components of the synchronization procedure.","PeriodicalId":258197,"journal":{"name":"2007 IEEE International Symposium on Precision Clock Synchronization for Measurement, Control and Communication","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133823214","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}

Since the precision time protocol (PTP) measures the delay of communication paths, it has to cope with network topology changes. The concept of peer-to-peer transparent clocks (TC), introduced with PTP version 2, facilitates the handling of path switchover by measuring the link delays from each node to its neighbors in advance. The parallel redundancy protocol (PRP) follows a different approach from the well-known reconfiguration protocols. It makes use of two independent Ethernet networks. Frames are replicated by the sending node and transmitted over both networks. Duplicates are discarded by the receiving node. There is no distinction between a working and a backup path. The combination of PTP and PRP is studied in this paper. Different models are presented and evaluated with respect to synchronization switchover and implementation issues. An experimental implementation is outlined. The results show that master clock failure as well as network failures can be handled with very low impact on synchronization quality.","PeriodicalId":258197,"journal":{"name":"2007 IEEE International Symposium on Precision Clock Synchronization for Measurement, Control and Communication","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114891575","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}
