Ko ngā whatunga whakawhitiwhiti kōrero ahumahi te pou tuarā o ngā wheketere hou me ngā ahumahi tukatuka, ā, he mahi nui tā rātou i roto i tā rātou mahi me te whai huatanga. Mai i ngā whare hanga motuka ki ngā whare matū uaua me ngā taiwhanga karetao matatau, ka pā nui te whiriwhiri i ngā taura whatunga ki te whai huatanga me te whai huatanga o te whakawhitiwhiti kōrero mīhini. Mā te whatunga kua hoahoatia pai ka taea te tuku raraunga me te pono, me te tere hoki, he mea nui tēnei i roto i ngā taiao e hiahia ana ki te aroturuki me te whakahaere i te wā tūturu. Ka arotahi tēnei tuhinga ki te whiriwhiri i waenga i a PROFIBUS me PROFINET.ngā taura.
1. He aha te PROFIBUS?
He paerewa pahi mara kua pakari a PROFIBUS i whakaurua mai i te mutunga o te tekau tau atu i 1980. Mā tēnei ka taea te whakawhitiwhiti kōrero i waenga i ngā kaiwhakahaere aunoatanga me ngā taputapu mara pēnei i ngā pūoko, ngā takirere, me ngā puku. He rongonui mō tōna pakari me tōna pono, e whakamahia whānuitia ana i roto i te hanga me te aunoatanga tukanga.
Ka whakamahia e PROFIBUS te whakawhitiwhiti kōrero raupapa i runga i te paparanga tinana RS-485. Ka tautokohia e ia ngā tere raraunga tae atu ki te 12 Mbps, ā, he pai mō ngā momo hononga raina, pahi rānei. He tino pai mō ngā taiao e hiahia ana ki te whakawhitiwhiti kōrero whakatau.
2. He aha te PROFINET?
He kawa whakawhitiwhiti kōrero e ahu mai ana i te Ethernet a PROFINET i whakawhanakehia e PROFIBUS me PROFINET International (PI). He mea hanga motuhake mō te whakawhiti raraunga tere-tere, wā-tūturu i roto i ngā whatunga ahumahi hou, hei tautoko i ngā mahi aunoatanga uaua.
Ko te PROFINET e hangai ana ki te hangarau Ethernet paerewa, ā, e tautoko ana i ngā tere raraunga mai i te 100 Mbps ki ngā tere Gigabit. Ko ōna hanganga whatunga ngāwari ko ngā hanganga whetu, raina, mowhiti, rākau rānei. He pai mō te aunoatanga mahi-teitei, te karetao, me te whakahaere nekehanga.
3. Ngā Taura PROFIBUS
I te mea e whakawhirinaki ana a PROFIBUS ki te tohu raupapa rerekē, me whakaiti te tāutanga taura i te pokanoa hikohiko (EMI) me te pupuri i te pono o te tohu. Ko ngā whakatakotoranga taura PROFIBUS noa ko:takirua miro kua āraia (STP) or takirua miro kore-ārai (UTP)me te ātete o te 100–120 ohms. E taunakihia ana ngā taura ārai i roto i ngā taiao ahumahi me te EMI teitei. I ngā reiti baud iti iho, ka taea e te roa o ngā taura te eke ki te 1200 mita. Me momo M12, M8, momo tīwiri rānei ngā hononga.
Whakamahia ngā taura kua whaimana a PROFIBUS hei whakarite i te hototahitanga, hurihia kia tika te whenua o ngā ārai hei whakaiti i te haruru, me te pupuri i te ara tika o te taura hei karo i ngā pokanoa.
4. Ngā Taura PROFINET
Ka whakamahia e PROFINET ngā taura Ethernet paerewa, me ngā taura whatunga arumoni. Mā te whiriwhiri tika i ngā taura ka taea te whakarite kia tere te whakawhitiwhiti kōrero, kia pono hoki, inā koa i roto i ngā taiao ahumahi uaua.
Ko ngā whakatakotoranga taura PROFINET noa ko Cat5e, Cat6, teitei ake rānei (he pai ake te whakamahi i te taura ā-ahumahi hei ārai). Mō te ārai, whakamahia te taura takahuri ārai (STP, S/FTP rānei) i roto i ngā taiao haruru. Ko ngā hononga e taunakitia ana ko te RJ45 Ethernet paerewa ā-ahumahi. Kaua ia wāhanga taura e neke ake i te 100 mita; me whakamahi ngā pana, ngā pūrua rānei mō ngā tawhiti roa ake.
Ngā Tikanga Pai o PROFINET:Whakamahia ngā taura Ethernet taumata ahumahi i hangaia mō ngā taiao uaua; kia tika te whenua me te ārai; whakamahia ngā pana whatunga ahumahi hei whakawhānui, hei wehewehe rānei i te whatunga.
5. Ko tēhea taura me whiriwhiri e koe?
Whakamahia ngā taura PROFIBUS:
-
Mō ngā pūnaha tuku iho, mō ngā tono whakawhitiwhiti raupapa rānei
-
I roto i ngā taiao he iti noa te pokanoa hikohiko
-
Ina he iti te utu, he rawaka te whakawhitiwhiti kōrero raupapa pono
-
Mō ngā taura poto i roto i ngā mīhini, i ngā kāpata whakahaere rānei
Whakamahia ngā taura PROFINET:
-
Mō ngā tono tere-teitei, whānui-aho teitei
-
I roto i ngā taiao EMI-teitei e hiahia ana ki ngā taura Ethernet ārai
-
Mō ngā āhua whatunga ngāwari, tauine hoki
-
Ina whakauru atu ki ngā taputapu hou e hangai ana ki te Ethernet, me te hanga pūnaha ā-mua
6. Ngā Tohutohu Tāutanga mō te Whakawhitiwhiti Kōrero Pono
-
Te Parepare Tika:Whakamahia he parengangā taurame te whakarite kia tika te whenua o ngā whakangungu rakau.
-
Te Ara Taura:Puritia ngā taura whakawhitiwhiti kōrero kia matara atu i ngā raina hiko me ngā pūtake o ngā pokanoa.
-
Ngā Hononga me ngā Pūrua:Whakamahia ngā hononga ā-ahumahi, ā, kia tino mau te hononga.
-
Wāhanga:Hoahoahia ngā whatunga hei whakaiti i te roa o ngā wāhanga me te karo i ngā koropiko kore e hiahiatia.
-
Ngā Whakaaroaro Taiao:Kōwhiria ngā taura kua whakatauria mō te pāmahana, te pānga ki ngā matū, me te ahotea ā-pūkaha o te taiao.
He mahi nui tā ngā taura PROFIBUS me PROFINET, engari he mea whakarite kia rite ki ngā tono motuhake. Ko PROFIBUS te tohu o te pahi tukatuka, ā, kua waiho hei whiringa pono, inā koa i roto i ngā ahumahi tukatuka tuku iho e whakawhirinaki ana ki tōna hoahoa pakari. He maha ngā wā e hiahiatia ana he pumau me te ōritetanga mō ēnei taiao, ā, ka whai hua mai i te kaha o PROFIBUS ki te pupuri i te whakawhitiwhiti kōrero pono i runga i ngā tawhiti roa me ngā whirihoranga whatunga uaua.
I te wā e whiriwhiri ana koe, whakaarohia ō hanganga, taiao, me ngā whāinga ā muri ake nei. Kōwhiria ngā otinga he pakari, he kaha te mahi, ā, he pono ahakoa i raro i ngā āhuatanga tino uaua.
