Manetwork ekukurukurirana emaindasitiri ndiwo musimboti wemafekitori emazuva ano uye maindasitiri ekugadzirisa, achiita basa rakakosha mukushanda kwawo uye mashandiro awo. Kubva kumafekitori ekugadzira mota kusvika kune zvivakwa zvemakemikari zvakaoma uye marabhoritari epamusoro emarobhoti, kusarudzwa kwetambo dzenetwork kunogona kukanganisa zvakanyanya kushanda zvakanaka uye kushanda kwekutaurirana kwemuchina. Network yakagadzirwa zvakanaka inoita kuti data ritumirwe zvakavimbika uye nekukurumidza, izvo zvakakosha munzvimbo dzinoda kutariswa nekudzorwa nenguva chaiyo. Chinyorwa chino chichatarisa maitiro ekusarudza pakati pePROFIBUS nePROFINETtambo.
1. Chii chinonzi PROFIBUS?
PROFIBUS imhando ye "fieldbus standard" yakatangwa kuma1980. Inonyanya kubvumira kutaurirana pakati pevanodzora otomatiki nemidziyo yemumunda yakaita semasensa, mavharuvhu, nemadhiraivha. Inozivikanwa nekusimba kwayo uye kuvimbika, inowanzoshandiswa mukugadzira uye kugadzira otomatiki.
PROFIBUS inoshandisa kutaurirana kwese kwakavakirwa paRS-485 physical layer. Inotsigira data rates inosvika 12 Mbps uye yakakodzera kune line kana bhazi topology. Yakanyatsokodzera nzvimbo dzinoda kutaurirana kwe deterministic.
2. Chii chinonzi PROFINET?
PROFINET inzira yekutaurirana yakavakirwa paEthernet yakagadzirwa nePROFIBUS nePROFINET International (PI). Yakagadzirirwa zvakananga kuchinjana data nekukurumidza uye panguva chaiyo muma network emazuva ano emaindasitiri, ichitsigira mabasa akaomarara e otomatiki.
PROFINET yakavakirwa patekinoroji yeEthernet yakajairwa uye inotsigira data rates kubva pa100 Mbps kusvika pakumhanya kweGigabit. Magadzirirwo ayo enetwork anochinjika anosanganisira nyeredzi, mutsetse, mhete, kana maumbirwo emiti. Yakakodzera automation inoshanda zvakanyanya, robotics, uye motion control.
3. Tambo dzePROFIBUS
Sezvo PROFIBUS ichivimba ne differential serial signaling, kuiswa kwetambo kunofanira kuderedza electromagnetic interference (EMI) uye kuchengetedza kuvimbika kwechiratidzo. Zvakajairika PROFIBUS cable zvinosanganisirapeya yakakoshwa yakachengetedzwa (STP) or peya yakamonyoroka isina kudzivirirwa (UTP)ine impedance ye100–120 ohms. Tambo dzakadzivirirwa dzinokurudzirwa munzvimbo dzemaindasitiri dzine EMI yakakwira. Pakureba kwebaud kwakaderera, kureba kwetambo kunogona kusvika mamita 1200. Zvinobatanidza zvinofanirwa kunge zviri zvemhando yeM12, M8, kana screw-terminal.
Shandisa tambo dzakasimbiswa nePROFIBUS kuti uve nechokwadi chekuti dzinoenderana, dziviriro dzakagadzirwa pasi zvakanaka kuderedza ruzha, uye kuchengetedza nzira dzakakodzera dzetambo kudzivirira kukanganiswa.
4. Tambo dzePROFINET
PROFINET inoshandisa tambo dzeEthernet dzakajairwa, ichishandisa tambo dzenetwork dzebhizinesi. Kusarudzwa kwetambo kwakakodzera kunovimbisa kutaurirana nekukurumidza uye kwakavimbika, kunyanya munzvimbo dzakaoma dzemaindasitiri.
Zvinodiwa zvetambo dzePROFINET ndezvekuti Cat5e, Cat6, kana kupfuura (zviri nani kuti dzishandiswe muindasitiri). Kuti dzishandiswe mumidziyo, shandisa tambo dzakatwasuka dzakadzivirirwa (STP kana S/FTP) munzvimbo dzine ruzha. Zvinokurudzirwa kuti zvisanganisirwe mumidziyo yemagetsi zvishandiswe muindasitiri yeRJ45 Ethernet. Chikamu chega chega chetambo hachifanirwe kudarika mamita zana; daro refu rinoda maswitch kana ma repeater.
Maitiro Akanakisisa ePROFINET:Shandisa tambo dzeEthernet dzemhando yepamusoro dzakagadzirirwa nzvimbo dzakaoma; iva nechokwadi chekuti pasi rayo rakasimba uye rakachengetedzwa zvakanaka; shandisa maswichi enetwork eindasitiri kuwedzera kana kupatsanura network.
5. Ndeipi Cable Yaunofanira Kusarudza?
Shandisa tambo dzePROFIBUS:
-
Kune masisitimu echinyakare kana mashandisirwo ekutaurirana akatevedzana
-
Munzvimbo dzisina kukanganiswa kwakanyanya kwemagetsi
-
Kana kutaurirana kwakavimbika uye kwakatevedzana kuchibatsira pamutengo wakaderera zvakakwana
-
Kuti tambo dzishande kwenguva pfupi mukati memakabati emuchina kana ekudzora
Shandisa tambo dzePROFINET:
-
Kune maapplication anomhanya zvikuru uye ane bandwidth yepamusoro
-
Munzvimbo dzine EMI yakawanda dzinoda tambo dzeEthernet dzakadzivirirwa
-
Kune magadzirirwo enetwork anochinjika uye anogona kukura
-
Pakubatanidza nemidziyo yemazuva ano yakavakirwa paEthernet uye kuvaka masisitimu anodzivirira ramangwana
6. Mazano Ekuisa Kuti Ukwanise Kutaurirana Zvakavimbika
-
Kudzivirira Kwakakodzera:Shandisa kudzivirirwatambouye simbisa kuti nhoo dzakamiswa zvakanaka.
-
Kufambisa Nheyo:Chengeta tambo dzekutaurirana kure netambo dzemagetsi uye zvinhu zvinokanganisa mashandiro.
-
Zvinobatanidza uye Zviteshi:Shandisa zvinobatanidza zvemhando yepamusoro uye iva nechokwadi chekuti materminals akachengeteka.
-
Kupatsanura:Gadzira ma network kuti uderedze hurefu hwezvikamu uye kudzivirira zvipingamupinyi zvisina kufanira.
-
Kufunga Nezvezvakatipoteredza:Sarudza tambo dzakatarwa zvichienderana nekupisa, kusvibiswa nemakemikari, uye kushushikana kwemakemikari munharaunda.
Tambo dzePROFIBUS nePROFINET dzese dzinoita mabasa akakosha asi dzakagadzirirwa mashandisirwo chaiwo. PROFIBUS inomiririra process fieldbus uye yave sarudzo yakavimbika, kunyanya mumaindasitiri echinyakare eprocess ayo anovimba nehunyanzvi hwayo hwakasimba. Nzvimbo idzi dzinowanzoda kugadzikana uye kugara kwenguva refu uye dzinobatsirwa nekugona kwePROFIBUS kuchengetedza kutaurirana kwakavimbika pamusoro penzvimbo refu uye marongero akaomarara enetwork.
Pakusarudza, funga nezvezvivakwa zvako, nharaunda, uye zvinangwa zveramangwana. Sarudza mhinduro dzinogara kwenguva refu, dzinoshanda zvakanaka, uye dzakavimbika kunyangwe mumamiriro ezvinhu akaomarara.
