Abstract:V diplomskem delu je opisana izdelava gonilnika za zajem podatkov v realnem-času pri visokih frekvencah iz omrežja EtherCAT, in sicer s pomočjo odprtokodnih rešitev za okolje Linux. Na začetku je primerjava dveh razširjenih rešitev za strogi realni-čas v operacijskem sistemu Linux z namenom ugotoviti, ali sta rešitvi enakovredni. Primerjani rešitvi sta v drugem delu implementirani in opravljene so primerjalne meritve. Izbrana rešitev Linux RT-Preempt je nato uporabljena kot osnova za razvoj jedrnega gonilnika. Gonilnik je razvit kot jedrni modul za operacijski sistem Linux, zasnovan na odprtokodni rešitvi IgH EtherCAT Master. Gonilnik je testiran, rezultati opravljenih meritev pa primerjani s pričakovanimi.

Title:DRIVER FOR REAL-TIME PACKET ACQUISITION FROM ETHERCAT NETWORK
Abstract:In this diploma thesis we develop a module for data acquisition from EtherCAT network using an open-source solution for real-time under Linux platform. In the beginning of the thesis, we compared two widely recognized solutions for hard real-time under the operating system Linux: RT_Preempt and RTAI. Next, we implemented both solutions and used benchmarks to check jitter of the developed systems. Further, Linux RT-Preempt was used as a base for the development of kernel module for data acquisition. Development of Linux kernel module was based on an open-source solution IgH EtherCAT Master. We also benchmark the developed module and compare the results with the expected ones.
Keywords:Linux, real-time, EtherCAT, RT-Preempt, RTAI, IgH EtherCAT Master, open source
