20.500.12556/RUL-81662 Računalnik Raspberry Pi v vlogi PLK-ja Raspberry Pi computer employed as a PLC V modernem svetu, kjer vse stremi k avtomatizaciji, se je skoraj vsak izmed nas že srečal s procesom, ki ga vodi programirljivi logični krmilnik (PLK). Z avtomatizacijo in programiranjem se vse bolj srečujemo v šolstvu in celo doma. PLK-ji so večinoma zelo dragi, zato je pred nakupom potrebno temeljito premisliti, ali se bo tak nakup izplačal. V šolstvu se tako redko srečamo s PLK-ji, saj se zaradi njihove visoke cene za nakup odloči le peščica šol. Posledično nima vsak možnosti, da bi se preizkusil v razvijanju aplikacij za PLK-je in tako marsikatera potencialna inovativna ideja ostane nerealizirana. Cenovno dostopni računalnik Raspberry Pi z razširitvenim modulom PiFace Digital 2 pa približuje svet avtomatizacije ne samo v šolstvu, ampak tudi v domači rabi. V diplomskem delu sem preizkusil in opisal računalnik Raspberry Pi in razširitveni modul PiFace Digital 2, ki ju skupaj uporabimo v vlogi PLK-ja. Opisal sem tudi vse nastavitve in korake za aktivacijo, ki so potrebni za zagon in pravilno delovanje. Za preizkus računalnika Raspberry Pi v vlogi PLK-ja sem s programskim okoljem CODESYS razvil aplikacijo za dviganje in spuščanje modela zapornice in uspešno preizkusil njeno delovanje. Due to worldwide modernization, many people have come across a process, which is controlled by a programmable logic controller (PLC). Automation and programming have already become a part of everyday life and they are also involved in our educational system. But since PLC is a rather expensive tool, there is a clear need to carefully evaluate its purchase decision and define whether it will bring the expected results. PLC’s high price is unfortunately still an unbridgeable obstacle for many schools. Consequentially, not many students have the opportunity to test their skills in developing applications for PLC’s. Thus, many potentially innovative ideas are still left unrealized. However, the arrival of the cheap Raspberry Pi computer and its PiFace Digital 2 expansion module has made the world of automatization more accessible not only for schools, but for home projects as well. In my thesis I have described the Raspberry Pi computer and the PiFace Digital 2 expansion module, which together form a PLC, and tested both in practice. Furthermore, I have described all settings and activation steps that are required for their successful boot and operation. For the purpose of testing how the Raspberry Pi computer functions as a PLC, I have developed and also successfully tested an application in CODESYS environment, which controls a model barrier. računalnik Raspberry Pi razširitveni modul PiFace Digital 2 programsko okolje CODESYS PLK avtomatizacija Raspberry Pi computer PiFace Digital 2 expansion module CODESYS environment PLC automation true false false Slovenski jezik Angleški jezik Diplomsko delo 2016-04-25 14:50:06 2016-04-25 14:50:08 2022-08-01 22:18:12 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 33961 Mravlje_Klemen_-_Racunalnik_Raspberry_Pi_v_vlogi_PLK-ja.pdf Mravlje_Klemen_-_Racunalnik_Raspberry_Pi_v_vlogi_PLK-ja.pdf 1 DF588D86D66037D50F4F4526344B6536 55e6f630161d912ffda2fa3ee67fffb138496e096ab6c8f2eab1540d2fe146d3 709435d8-a1ad-11eb-a523-00155dcfd717 20.500.12556/rul/ee78a590-f11f-405e-90d5-5f4bd5ccb1a9 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=81876 Fakulteta za elektrotehniko 0 0 0
