Maindasitiri ekukurukurirana network ndiwo musimboti wemafekitori emazuva ano uye maindasitiri ekugadzirisa, achiita basa rakakosha mukushanda nekushanda kwawo. Kubva kumiti yekugadzira mota kusvika kune yakaoma makemikari zvivakwa uye epamberi marobhoti labs, kusarudzwa kwetambo dzenetiweki kunogona kukanganisa zvakanyanya kushanda uye kushanda kwemuchina kutaurirana. Iyo network yakanyatsogadzirwa inovimbisa kuti data inofambiswa zvakavimbika uye nekukurumidza, izvo zvakakosha munzvimbo dzinoda chaiyo-nguva yekutarisa uye kutonga. Ichi chinyorwa chinotarisa maitiro ekusarudza pakati pePROFIBUS nePROFINETcables.
1. Chii chinonzi PROFIBUS?
PROFIBUS ndeye yakakura fieldbus standard yakaunzwa mukupera kwema1980s. Iyo inonyanya kugonesa kutaurirana pakati peautomation controllers uye zvishandiso zvemumunda senge sensors, mavharuvhu, uye madhiraivha. Iyo inozivikanwa nekusimba kwayo uye kuvimbika, inowanzoshandiswa mukugadzira uye kugadzirisa otomatiki.
PROFIBUS inoshandisa serial kutaurirana zvichibva pane RS-485 yemuviri layer. Inotsigira data rates kusvika ku12 Mbps uye inokodzera mutsara kana bhasi topology. Iyo inonyanya kukodzera kune nharaunda dzinoda deterministic kutaurirana.
2. Chii chinonzi PROFINET?
PROFINET iEthernet-based communication protocol yakagadzirwa nePROFIBUS uye PROFINET International (PI). Yakagadzirirwa yakanyatso kumhanyisa, chaiyo-nguva yekuchinjana data mumaindasitiri emazuva ano maindasitiri, achitsigira yakaoma otomatiki mabasa.
PROFINET yakavakirwa pane yakajairwa Ethernet tekinoroji uye inotsigira data mitengo kubva pa100 Mbps kusvika kuGigabit kumhanya. Yayo inoshanduka network topology inosanganisira nyeredzi, mutsara, mhete, kana zvimiro zvemuti. Iyo yakakodzera kune yakakwirira-inoshanda otomatiki, marobhoti, uye inofamba kutonga.
3. PROFIBUS Cables
Sezvo PROFIBUS ichivimba nekusiyanisa serial kusaina, kuisirwa tambo kunofanirwa kudzikisa kukanganiswa kwemagetsi (EMI) uye kuchengetedza chiratidzo chekuvimbika. Yakajairika PROFIBUS tambo yakatarwa inosanganisirashielded twisted pair (STP) or isina kuvharidzirwa yakamonyoroka pair (UTP)ine impedance ye100-120 ohms. Tambo dzakadzivirirwa dzinokurudzirwa munzvimbo dzeindasitiri dzine yakakwira EMI. Pamitengo yakaderera yebaud, kureba kwetambo kunogona kusvika kusvika 1200 metres. Zvibatanidza zvinofanirwa kunge zviri M12, M8, kana screw-terminal mhando.
Shandisa tambo dzakasimbiswa-PROFIBUS kuti uve nechokwadi chekuenderana, nhovo dzepasi zvakanaka kuderedza ruzha, uye chengetedza nzira yakakodzera yetambo kudzivirira kukanganisa.
4. PROFINET Cables
PROFINET inoshandisa yakajairwa Ethernet cabling, leveraging commercial network tambo. Kusarudzwa kwakakodzera kwetambo kunovimbisa kukurumidza-kumhanya, kutaurirana kwakavimbika, kunyanya munzvimbo dzakaoma dzeindasitiri.
Yakajairika PROFINET tambo yakatarwa ndeye Cat5e, Cat6, kana yepamusoro (zvichida maindasitiri-giredhi akadzivirirwa). Pakudzivirira, shandisa shielded twisted pair (STP kana S/FTP) munzvimbo dzine ruzha. Zvinokurudzirwa zvinobatanidza iindasitiri-yakajairwa RJ45 Ethernet. Chikamu chimwe nechimwe chetambo hachifanirwe kudarika 100 metres; kureba kunoda ma switch kana anodzokorora.
PROFINET Maitiro Akanakisisa:Shandisa maindasitiri-giredhi Ethernet tambo dzakagadzirirwa nharaunda dzakaoma; iva nechokwadi chekugadzirisa pasi uye kudzivirira; shandisa maindasitiri network switch kuwedzera kana kupatsanura network.
5. Ndeipi Cable Yaunofanira Kusarudza?
Shandisa PROFIBUS tambo:
-
Zvechinyakare masisitimu kana serial yekutaurirana maapplication
-
Munzvimbo dzine kushomeka kwemagetsi kukanganiswa
-
Kana inodhura-inoshanda, yakavimbika serial kutaurirana yakakwana
-
Kune pfupi tambo inomhanya mukati memichina kana kutonga makabati
Shandisa PROFINET tambo:
-
Kune yakakwirira-kumhanya, yakakwirira-bandwidth application
-
Munzvimbo dzakakwirira-EMI dzinoda tambo dzakavharidzirwa dzeEthernet
-
Zvekuchinjika, scalable network topology
-
Kana uchibatanidza neazvino Ethernet-yakavakirwa zvishandiso uye kuvaka ramangwana-uchapupu masisitimu
6. Kuisa Mazano eKukurukurirana Kwakavimbika
-
Kudzivirira Kwakakodzera:Shandisa nhovocablesuye ona kuti nhovo dzakadzika zvakanaka.
-
Cable Routing:Chengetedza tambo dzekukurukurirana kure netambo dzemagetsi uye kunovhiringidza masosi.
-
Connectors uye Terminals:Shandisa maindasitiri-giredhi zvibatanidza uye ona kuti materminal akachengeteka.
-
Segmentation:Dhizaina network kuderedza kureba kwechikamu uye kudzivirira zvishwe zvisina basa.
-
Mafungiro Ezvakatipoteredza:Sarudza tambo dzakayerwa tembiricha, kuratidzwa kwekemikari, uye kushushikana kwemagetsi munzvimbo.
Ose ari maviri PROFIBUS uye PROFINET tambo dzinotamba dzakakosha mabasa asi dzakagadzirirwa kune chaiwo maapplication. PROFIBUS inomiririra processbus uye yave sarudzo yakavimbika, kunyanya mumaindasitiri echinyakare maindasitiri anovimba neayo akasimba ekuvaka. Idzi nharaunda dzinowanzoda kugadzikana uye kuenderana uye kubatsirwa kubva mukukwanisa kwePROFIBUS kuchengetedza kutaurirana kwakavimbika pamusoro pemadaro marefu uye yakaoma network masisitimu.
Paunenge uchisarudza, funga nezvezvivakwa zvako, nharaunda, uye zvinangwa zvenguva yemberi. Sarudza mhinduro dzakasimba, dzinoshanda, uye dzakavimbika kunyangwe pasi pemamiriro akaomarara.
