Mō ngā pūnaha hiko, he mea nui te aroturuki i te wā-tūturu. Heoi, nā te mea he maha ngā taputapu o nāianei e whakawhirinaki ana ki te whakahaere o te pūnaha hiko, he tino uaua te aroturuki i te wā-tūturu mō ngā kaimahi whakahaere me te tiaki. Ahakoa he maha ngā mahere whakarerekētanga me te whakapai ake a te nuinga o ngā pūnaha hiko, he maha ngā wā kāore e taea te whakatinana i aua mahere nā te iti o ngā tahua. Mō ngā teihana hiko iti he iti te tahua, ko te otinga pai ko te hono i te hanganga o nāianei ki te whatunga IEC 61850, ka taea ai te whakaiti nui i te haumitanga e hiahiatia ana.
Kua tāutahia e ngā pūnaha hiko o nāianei kua roa e whakahaerehia ana mō ngā tekau tau te maha o ngā taputapu e ahu mai ana i ngā kawa whakawhitiwhiti kōrero motuhake, ā, ehara i te mea tino whai hua te whakakapi i a rātou katoa i te wā kotahi. Mena kei te hiahia koe ki te whakapai ake i te pūnaha aunoatanga hiko me te whakamahi i tētahi pūnaha SCADA hou e ahu mai ana i te Ethernet hei aroturuki i ngā taputapu mara, ko te mea nui ko te whakatutuki i te utu iti rawa me te iti rawa o te whakauru tangata. Mā te whakamahi i ngā otinga hononga pēnei i ngā tūmau taputapu raupapa, ka taea e koe te whakatū hononga mārama i waenga i tō pūnaha SCADA hiko e ahu mai ana i te IEC 61850 me ō taputapu mara e ahu mai ana i te kawa motuhake. Ka tākaihia ngā raraunga kawa motuhake o ngā taputapu mara ki roto i ngā mōkihi raraunga Ethernet, ā, ka taea e te pūnaha SCADA te whakatutuki i te aroturukitanga wā-tūturu o ēnei taputapu mara mā te wetewete.
He ngāwari te whakamahi i ngā kēti hiko taumata-teihana-ipurangi Raupapa MGate 5119 a Moxa, ā, he tere te whakatū i te whakawhitiwhiti kōrero maeneene. Ehara i te mea ka āwhina noa tēnei raupapa kēti ki te whakatutuki i te whakawhitiwhiti kōrero tere i waenga i ngā taputapu Modbus, DNP3, IEC 60870-5-101, IEC 60870-5-104 me te whatunga whakawhitiwhiti kōrero IEC 61850, engari ka tautoko hoki i te mahi tukutahi wā NTP hei whakarite kia kotahi te tohu wā o ngā raraunga. Kei te raupapa MGate 5119 anō hoki he kaihanga kōnae SCL kua hangaia, he mea watea mō te whakaputa i ngā kōnae SCL kēti-teihana-ipurangi, ā, kāore koe e hiahia ki te whakapau wā me te moni ki te kimi i ētahi atu taputapu.
Mō te aroturukitanga wā-tūturu o ngā taputapu mara mā te whakamahi i ngā kawa motuhake, ka taea hoki te whakamahi i ngā tūmau taputapu raupapa NPort S9000 a Moxa hei hono i ngā IED raupapa ki ngā hanganga e hangai ana ki te Ethernet hei whakapai ake i ngā teihana hiko tuku iho. Ka tautokohia e tēnei raupapa te 16 ngā tauranga raupapa me te 4 ngā tauranga whakawhiti Ethernet, ka taea te tākai i ngā raraunga kawa motuhake ki roto i ngā mōkihi Ethernet, me te hono ngāwari i ngā taputapu mara ki ngā pūnaha SCADA. Hei tāpiri, ka tautokohia e te raupapa NPort S9000 ngā mahi tukutahi wā NTP, SNTP, IEEE 1588v2 PTP, me IRIG-B, ka taea te tukutahi-ake me te tukutahi i ngā taputapu mara o nāianei.
I a koe e whakapakari ana i tō whatunga aroturuki me te whakahaere i tō whatunga teihana iti, me whakapai ake e koe te haumarutanga o ngā taputapu whatunga. Ko ngā tūmau whatunga taputapu raupapa me ngā kēti kawa a Moxa ngā kaiawhina tika hei whakatau i ngā take haumarutanga, hei āwhina i a koe ki te whakaoti i ngā tūponotanga huna e puta mai ana i te whatunga taputapu mara. E tutuki ana ngā taputapu e rua i ngā paerewa IEC 62443 me NERC CIP, ā, he maha ngā mahi haumarutanga kua hangaia hei tiaki whānui i ngā taputapu whakawhitiwhiti kōrero mā roto i ngā mahi pēnei i te manatoko kaiwhakamahi, te whakatakoto i te rārangi IP e whakaaetia ana kia uru atu, te whirihoranga me te whakahaere taputapu i runga i te haumarutanga kawa HTTPS me te TLS v1.2 mai i te urunga kore mana. Ka mahi auau hoki te otinga a Moxa i ngā matawai ngoikoretanga haumarutanga, ā, ka mahi i ngā mahi e tika ana i te wā tika hei whakapai ake i te haumarutanga o ngā taputapu whatunga teihana iti i roto i te ahua o ngā papaki haumarutanga.
Hei tāpiritanga, kei te tutuki ngā tūmau taputapu raupapa me ngā kēti kawa a Moxa i ngā paerewa IEC 61850-3 me IEEE 1613, e whakarite ana i te mahi whatunga pumau me te kore e pāngia e te taiao uaua o ngā teihana hiko.
