Cov tes hauj lwm sib txuas lus hauv kev lag luam yog lub hauv paus ntawm cov chaw tsim khoom niaj hnub thiab cov txheej txheem kev lag luam, ua lub luag haujlwm tseem ceeb hauv lawv txoj haujlwm thiab kev ua haujlwm. Txij li cov chaw tsim khoom tsheb mus rau cov chaw tsim tshuaj lom neeg nyuaj thiab cov chaw kuaj mob robotics siab heev, kev xaiv cov xov hlau hauv network tuaj yeem cuam tshuam rau kev ua haujlwm zoo thiab kev ua haujlwm ntawm kev sib txuas lus hauv tshuab. Lub network tsim zoo ua kom ntseeg tau tias cov ntaub ntawv raug xa mus tau zoo thiab sai, uas yog qhov tseem ceeb hauv cov chaw ib puag ncig uas xav tau kev saib xyuas thiab tswj xyuas lub sijhawm tiag tiag. Tsab xov xwm no yuav tsom mus rau yuav ua li cas xaiv ntawm PROFIBUS thiab PROFINETcov xov hlau.
1. PROFIBUS yog dab tsi?
PROFIBUS yog ib qho qauv fieldbus uas tau tsim tawm thaum xyoo 1980s. Nws feem ntau ua rau muaj kev sib txuas lus ntawm cov tswj kev ua haujlwm tsis siv neeg thiab cov khoom siv hauv thaj chaw xws li cov sensors, valves, thiab drives. Nws yog lub npe nrov rau nws qhov kev ruaj khov thiab kev ntseeg tau, feem ntau siv rau hauv kev tsim khoom thiab cov txheej txheem automation.
PROFIBUS siv kev sib txuas lus serial raws li RS-485 txheej txheej. Nws txhawb nqa cov ntaub ntawv tus nqi txog li 12 Mbps thiab tsim nyog rau kab lossis tsheb npav topology. Nws yog qhov tshwj xeeb tshaj yog zoo rau cov chaw uas xav tau kev sib txuas lus deterministic.
2. PROFINET yog dab tsi?
PROFINET yog ib qho kev sib txuas lus raws li Ethernet uas PROFIBUS thiab PROFINET International (PI) tsim. Nws yog tsim tshwj xeeb rau kev sib pauv cov ntaub ntawv ceev ceev thiab lub sijhawm tiag tiag hauv cov tes hauj lwm niaj hnub no, txhawb nqa cov haujlwm automation nyuaj.
PROFINET yog siv cov thev naus laus zis Ethernet txheem thiab txhawb nqa cov ntaub ntawv ceev ntawm 100 Mbps mus txog Gigabit. Nws cov qauv network topology muaj xws li lub hnub qub, kab, nplhaib, lossis cov qauv ntoo. Nws yog qhov tsim nyog rau kev ua haujlwm siab automation, robotics, thiab kev tswj kev txav mus los.
3. Cov Cables PROFIBUS
Vim tias PROFIBUS vam khom rau qhov sib txawv ntawm cov cim qhia sib txuas, kev teeb tsa cable yuav tsum txo qis kev cuam tshuam hluav taws xob (EMI) thiab tswj kev ncaj ncees ntawm cov cim. Cov lus qhia tshwj xeeb ntawm PROFIBUS cable suav nrogCov khub sib txuas uas muaj cov hlau tiv thaiv (STP) or Cov khub sib txuas tsis muaj hlau thaiv (UTP)nrog rau qhov impedance ntawm 100–120 ohms. Cov xov hlau uas muaj shielded raug pom zoo rau hauv cov chaw ua haujlwm uas muaj EMI siab. Ntawm qhov baud rates qis dua, qhov ntev ntawm cov xov hlau tuaj yeem ncav cuag txog li 1200 meters. Cov khoom sib txuas yuav tsum yog M12, M8, lossis hom ntsia hlau-terminal.
Siv cov cables uas tau ntawv pov thawj PROFIBUS kom ntseeg tau tias sib xws, tiv thaiv cov ntaub thaiv av kom zoo kom txo tau suab nrov, thiab tswj cov cable routing kom zoo kom tsis txhob muaj kev cuam tshuam.
4. Cov Cables PROFINET
PROFINET siv cov kab hluav taws xob Ethernet txheem, siv cov kab hluav taws xob hauv network rau kev lag luam. Kev xaiv cov kab hluav taws xob kom raug ua kom muaj kev sib txuas lus ceev ceev thiab txhim khu kev qha, tshwj xeeb tshaj yog nyob rau hauv cov chaw ua haujlwm hnyav.
Cov lus qhia tshwj xeeb ntawm PROFINET cable yog Cat5e, Cat6, lossis siab dua (qhov zoo dua yog qib kev lag luam uas muaj kev tiv thaiv). Rau kev tiv thaiv, siv cov khub sib txuas uas muaj kev tiv thaiv (STP lossis S/FTP) hauv cov chaw muaj suab nrov. Cov khoom sib txuas uas pom zoo yog RJ45 Ethernet tus qauv kev lag luam. Txhua ntu cable yuav tsum tsis pub tshaj 100 meters; qhov deb ntev dua yuav tsum muaj cov hloov lossis cov repeaters.
Cov Kev Xyaum Zoo Tshaj Plaws ntawm PROFINET:Siv cov cables Ethernet qib kev lag luam uas tsim los rau cov chaw ib puag ncig hnyav; xyuas kom meej tias muaj kev sib txuas hauv av thiab kev tiv thaiv zoo; siv cov hloov pauv network hauv kev lag luam los nthuav dav lossis faib lub network.
