A PLC, qualified for safety applications, is attractive because it saves a lot of time in verification and validation effort as compared to development of embedded control systems. We developed a tool, ST to MISRA-C translator, required for developing application program using Structured Text (ST) in a qualified PLC. The syntax and semantics of ST programming language is defined in the IEC 61131-3 standard. During the development of the translator, we found some issues with ST language syntax and semantics not pointed out by other researchers. These issues are discussed in this paper along with proposed changes in the ST language grammar for its unambiguous parsing.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"47 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":"128688219","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 main focus will be on the assessment of the admission control mechanism proposed for the RT-WiFi upper layer, that is based on a non-preemptive EDF scheduling algorithm combined with a mechanism that measures the blockage times on medium access of real-time stations due to retransmissions and delays. The goal is to achieve a good compromise between medium utilization and timeliness. This proposal is compared with HCCA, and the results show that RT-WiFi offers a significantly better behavior in what concerns the maximum number of admitted streams.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"35 10 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":"123514975","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 paper presents a motion trajectory generation method that suppresses the residual vibrations of such machines. First, we consider a residual vibration problem for a gantry-type crane that is widely used in industrial factories. The dynamics of the crane system is represented by a simple set of differential equations. Assuming that only a simple motion trajectory can be applied to an industrial controller, we propose a motion trajectory generation method that suppresses the residual vibration, which increases the production takt time. Simulation and experimental results demonstrate the effectiveness of the proposed method.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"227 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":"114103271","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 presented robot is designed for milling by moving the spindle along a desired trajectory generated in the Cartesian space. This means that for each point of the trajectory a solution of the inverse kinematics problem is needed. The resulting sequence of data creates the joint space trajectory that must be calculated on-line at high frequency. The paper shows how to decrease the calculation time preserving required accuracy, by augmenting the arithmetic-logic unit (ALU) of a microprocessor with custom instructions. The hardware implementation of the accelerator is described and results of calculations performed in an Altera FPGA chip are analyzed.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"2 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":"114201502","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 design of these systems is more and more complex due to flow and speed increase which pose hardware and software problems. The control engineers, who master the logic of control systems, also have to adapt themselves to the type of hardware already present at the customer (PLC) without necessarily mastering their programming. In the current logic of time-to-market reduction, these designers have to design the control of the systems more and more quickly without denying the Quality. To overcome these challenges, this paper presents a design flow which automates the generation of multiplatform control for the transitic systems. Based on model driven engineering and using a component approach, it has been implemented in a tool. We present the specificities of Straton and Unity generations and analyze the cost of adding a new platform.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"71 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":"114719150","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}

Whereas a standard switch ASIC provides sophisticated mechanisms for switching of non real-time frames, an attached FPGA implements cut-through switching of real-time frames. The proposed FPGA architecture supports configuration of port numbers, bandwidth reservation for real-time frames and utilizes flow-control mechanisms of the ASIC in order to keep frame buffer sizes low. Mapping exemplary RTE extensions of PROFINET IRT onto a Xilinx Spartan 6 FPGA demonstrates the capability of providing band-width reservation and cut-through-forwarding of real-time frames. Therefore, the approach benefits from the innovations made by the switch manufacturers, whereas only a small amount of functions has to be mapped onto an FPGA.","PeriodicalId":222799,"journal":{"name":"Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012)","volume":"70 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":"124230881","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}

Software prototyping, development as well as upgrading existing application must be done in a short time and the final applications must be robust and efficient to decrease CPU, memory, disk space, and network costs, increasing the competitiveness of the company.
