Ndezvipi zvakakosha zvinodiwa patambo dzeProfinet?

Profinet ndeye Ethernet-yakavakirwa maindasitiri ekutaurirana protocol, inoshandiswa zvakanyanya mu automation control masisitimu, Profinet tambo yakakosha zvinodiwa zvinonyanya kutariswa pahunhu hwemuviri, kuita kwemagetsi, kuchinjika kwezvakatipoteredza uye kuisirwa zvinodiwa. Ichi chinyorwa chichatarisa paProfinet tambo yekuongorora zvakadzama.

I. Hunhu Hwenyama

1, mhando yetambo

Shielded Twisted Pair (STP/FTP): Shielded Twisted Pair inokurudzirwa kuderedza electromagnetic interference (EMI) uye crosstalk. Shielded akamonyoroka maviri anogona kudzivirira zvekunze kukanganiswa kwemagetsi uye kugadzirisa kugadzikana uye kuvimbika kwekufambiswa kwechiratidzo.

Unshielded Twisted Pair (UTP): Unshielded Twisted Pair inogona kushandiswa munzvimbo dzine kushomeka kwemagetsi kukanganiswa, asi hazvikurudzirwe kushandiswa munzvimbo dzeindasitiri.

2, tambo chimiro

Mapaya mana etambo yakamonyoroka: tambo yeProfinet kazhinji ine mapeya mana eakamonyoroka-pairi tambo, imwe neimwe waya inoumbwa newaya mbiri dzekufambisa data uye magetsi (kana zvichidikanwa).

Wire Diameter: Madhayamita ewaya anowanzo 22 AWG, 24 AWG, kana 26 AWG, zvichienderana nedanho rekufambisa uye simba rechiratidzo. 24 AWG inokodzera kureba kwekufambisa madaro, uye 26 AWG inokodzera madaro mapfupi.

3, Chibatanidza

RJ45 connector: Profinet tambo dzinoshandisa yakajairwa RJ45 zvibatanidza kuti ive nechokwadi chekuenderana neProfinet zvishandiso.

Kukiya Mechanism: RJ45 zvibatanidza zvine kukiya michina inokurudzirwa kune nharaunda dzeindasitiri kudzivirira yakasununguka kubatana uye kuve nechokwadi chekuvimbika kwekubatana.

Chechipiri, kuchinjika kwezvakatipoteredza

1、Tembiricha yemhando

Yakakura tembiricha dhizaini: Profinet tambo inofanirwa kushanda nemazvo munzvimbo yakakura yekushisa, kazhinji inodiwa kutsigira -40 ° C kusvika 70 ° C tembiricha.

2、Chiyero chekudzivirira

Chiyero chekudzivirira chepamusoro: Sarudza tambo dzine mwero wekudzivirira wakakwira (semuenzaniso IP67) kudzivirira kupinda kweguruva nemhute yemvura kunzvimbo dzakaoma dzemaindasitiri.

3, Vibration uye kushomeka kuramba

Mechanical simba: Profinet tambo dzinofanirwa kuve nekudedera kwakanaka uye kushomeka kuramba, yakakodzera vibration uye kuvhunduka nharaunda.

4, makemikari kuramba

Oiri, asidhi uye alkali kuramba: Sarudza tambo dzine makemikari kuramba semafuta, asidhi uye alkali kuramba kuti uenderane neakasiyana maindasitiri nharaunda.

III. Installation Zvinodiwa

1, Wiring nzira

Dzivisa kupindira kwakasimba kwemagetsi: mu wiring inofanirwa kuyedza kudzivirira kuiswa kwakafanana neakakwira-voltage magetsi tambo, mota uye zvimwe zvakasimba zvemagetsi midziyo yekudzikisa kukanganiswa kwemagetsi.

Kurongeka kunonzwisisika: Kuronga kunonzwisisika kwenzira ye wiring, kudzivirira kukotama kwakanyanya kana kudzvanywa patambo, kuve nechokwadi chekuvimbika kwemuviri kwetambo.

2, Kugadzirisa nzira

Fixed bracket: Shandisa iyo yakakodzera yakagadziriswa bracket uye chigadziriso kuti uve nechokwadi chekuti tambo yakanyatsogadziriswa kudzivirira kuzunguzika kana kufamba kunokonzerwa neakasununguka kubatana.

Wire chiteshi uye pombi: Munzvimbo dzakaomarara, zvinokurudzirwa kushandisa waya kana pombi yekudzivirira tambo kudzivirira kukuvadzwa kwemuchina uye kukanganisa kwezvakatipoteredza.

IV. Certification uye zviyero

1, Kutevedzera mitemo

IEC 61158: Profinet tambo dzinoenderana nezviyero zveInternational Electrotechnical Commission (IEC), senge IEC 61158.

ISO/OSI modhi: Makomboti epurofiti anofanirwa kuenderana neiyo yemuviri layer uye data link layer zviyero zveiyo ISO/OSI modhi.

V. Sarudzo nzira

1, Kuongororwa kwezvinodiwa zvekushandisa

Kuendesa kureba: Zvinoenderana nekushandiswa chaiko kwechinhambwe chekufambisa kusarudza mhando yakakodzera yetambo. Kufambisa daro pfupi kunogona kusarudza 24 AWG tambo, kureba kwekufambisa kunokurudzirwa kusarudza 22 AWG tambo.

Mamiriro ekunze: Sarudza tambo yakakodzera zvinoenderana nekushisa, humidity, vibration uye zvimwe zvinhu zvenzvimbo yekuisa. Semuenzaniso, sarudza yakakwirira tembiricha inodzivirira tambo yeyakanyanya tembiricha nharaunda uye isina mvura tambo yenzvimbo ine hunyoro.

2, sarudza mhando yakakodzera yetambo

Shielded twisted-pair cable: Shielded twisted-pair cable inokurudzirwa kuti ishandiswe munzvimbo dzakawanda dzemaindasitiri kuderedza kukanganiswa kwemagetsi uye crosstalk.

Unshielded twisted-pair cable: chete munzvimbo ye electromagnetic interference idiki kushandisa isina kuvharidzirwa yakamonyoroka-pair cable.

3, funga kuchinjika kwezvakatipoteredza

Tembiricha renji, nhanho yekudzivirira, vibration uye kushomeka kuramba, makemikari kuramba: sarudza tambo dzinogona kushanda zvakatsiga munzvimbo chaiyo yekushandisa.
