ʻO Siemens PLC Nānā Huahana

ʻO ka nānā ʻana o nā huahana Siemens PLC Series
Ma ke ʻano he alakaʻi i ke kahua o ka automation, ʻoliʻoli ʻo Siemens i kahi kūlana kiʻekiʻe ma ka honua holoʻokoʻa no kāna mau huahana papahana programmable logic controller (PLC). Ma ke ʻano he kumu nui o nā ʻōnaehana automation ʻoihana, hana ʻo PLC i nā hana koʻikoʻi o ka mana, ka nānā ʻana a me ka hoʻoili ʻikepili. Me kāna hana kiʻekiʻe, hilinaʻi kiʻekiʻe a me ka laulā o nā hiʻohiʻona noi, ua lilo ʻo Siemens PLC series i koho mua no nā papahana automation. E hōʻike ana kēia ʻatikala i nā pūʻulu nui ʻelima o nā huahana Siemens PLC i nā kikoʻī: S7-200 Smart, S7-300 (hoʻopau ʻia), S7-400, S7-1200 a me S7-1500.

S7-200 Smart Series
ʻO ka S7-200 Smart series ka PLC compact hou loa i hoʻokuʻu ʻia e Siemens, i hoʻolālā ʻia no nā ʻōnaehana automation liʻiliʻi. Ke hoʻohana nei kēia pūʻulu o nā PLC i kahi mea hana kiʻekiʻe me ka mana wikiwiki a me ka hiki ke hoʻoili ʻikepili. ʻO kona liʻiliʻi liʻiliʻi e kūpono ia no nā manawa me ka palena palena. Kākoʻo ia i nā ʻano modula hoʻonui like ʻole, me nā modules I/O digital, nā modula I/O analog a me nā modula wela, hiki ke hoʻonui ʻia i nā modula 14. Loaʻa i ka S7-200 Smart series kahi kikowaena Ethernet i kūkulu ʻia a kākoʻo i nā protocol kamaʻilio e like me TCP/IP a me Modbus TCP, kahi kūpono no ka hoʻonohonoho ʻana a me ka pili pūnaewele. Eia kekahi, kākoʻo ia i nā protocol kamaʻilio lehulehu, e like me RS485, RS232, etc., a he mau hana kamaʻilio ikaika. Hoʻohana kēia pūʻulu PLC i ka hoʻolālā ʻenehana, hoʻololi i nā wahi paʻakikī, loaʻa ka mana anti-interference kiʻekiʻe, a hōʻoia i ka hana paʻa o ka ʻōnaehana.

ʻO Siemens PLC S7-200 SMART moʻo
Nā ʻāpana hana nui (e lawe ana i ka mana V2.3 ma ke ʻano he laʻana):
Hāʻawi i nā hiʻohiʻona CPU like ʻole, e like me CPU SR20, CPU ST20, CPU SR30, etc.
Hoʻohui ʻia nā ana holoʻokoʻa e like me 100mm ka laula a me 81mm i ka hohonu, akā ʻokoʻa ke kiʻekiʻe ma muli o ke kumu hoʻohālike.
Aia i loko o ka wahi mālama mea hoʻohana ka wahi e mālama ai i ka polokalamu, kahi e mālama ai i ka ʻikepili a me ka wahi mālama mālama, a ʻokoʻa ka mana ma muli o ke ʻano CPU.
ʻOkoʻa ka helu o nā helu I/O kikohoʻe o kēia mīkini ma muli o ke ʻano CPU. No ka laʻana, loaʻa iā CPU SR20 he 12 hoʻokomo/8 puka.
ʻOkoʻa nā ʻāpana hana e like me nā helu helu kiʻekiʻe a me nā puka puka pulse kiʻekiʻe ma muli o ke kumu hoʻohālike CPU.
Kūkākūkā:
Ethernet: 1, helu 10/100Mb/s.
Awa Serial: 1 (RS485), 1 awa serial hou (RS232/RS485 koho).
Kākoʻo i ka protocol PPI, ke kamaʻilio port manuahi, etc.

S7-300 moʻo (hoʻopau ʻia)
ʻO ka S7-300 series he PLC medium-sized mai Siemens, hoʻohana nui ʻia i ka automation ʻoihana. Hoʻohana kēia pūʻulu PLC i kahi hoʻolālā modular, a hiki ke koho ʻia nā modula I / O ʻokoʻa a me nā modula kamaʻilio e like me nā pono, a hiki ke maʻalahi ka hoʻonohonoho. Loaʻa i ka moʻo S7-300 nā mana hoʻoili ʻikepili ikaika a me nā mana hoʻokele kiʻekiʻe, kūpono no nā hana hoʻomalu paʻakikī. I ka manawa like, kākoʻo ʻo ia i ke kamaʻilio I/O a me PROFIBUS, e hoʻomaikaʻi ana i ka hilinaʻi a me ka maʻalahi o ka ʻōnaehana. ʻOiai ua hoʻopau ʻia ka moʻo S7-300, ʻoi aku ka maikaʻi o kāna noi ākea a me ka hana maikaʻi loa i nā papahana automation medium-sized.
2. Siemens PLC S7-300 moʻo
Module mana:
Hāʻawi i nā modula mana like ʻole, e like me 120 / 230VAC input, 24VDC / 2A output; 120/230VAC komo, 24VDC/5A puka, etc.
ʻĀpana hana kikowaena (CPU):
Hāʻawi i nā hiʻohiʻona CPU like ʻole, e like me CPU 312, CPU 314, CPU 315-2DP, etc.
ʻO nā ʻāpana hana e like me ka hoʻomanaʻo hana, ka manawa hana bit, nā helu DI/DO a me AI/AO ma muli o ke kumu hoʻohālike CPU.
Kākoʻo kekahi mau hiʻohiʻona CPU PROFIBUS-DP master/slave interface, PROFINET interface, etc.
IO module:
Hāʻawi i nā ʻano modula hoʻokomo kikohoʻe a me nā modula puka kikohoʻe.
ʻOkoʻa ka helu o nā helu hoʻokomo a me nā helu puka ma muli o ke ʻano hoʻohālike. No ka laʻana, ʻo ka SM321 digital input module he 16 mau helu, 32 mau helu a me nā kikoʻī ʻē aʻe.

S7-400 moʻo
ʻO S7-400 series kahi PLC nui o Siemens, kūpono i nā ʻōnaehana paʻakikī a me nā ʻōnaehana nui. Ke hoʻohana nei kēia pūʻulu PLC i nā mea hana kiʻekiʻe me nā mana hana ikaika a me ka hilinaʻi kiʻekiʻe. Kākoʻo ka moʻo S7-400 i nā modula hoʻonui like ʻole, me nā modules redundant a me ka hewa-tolerant modules, e hoʻokō i nā koi mana paʻakikī. I ka manawa like, kākoʻo ia i nā ʻoihana ʻenehana e like me PROFINET a me PROFIBUS, a he mau hana kamaʻilio ikaika. Loaʻa i ka S7-400 nā hana palekana a me ka hoʻolālā redundant e hōʻoia i ka paʻa a me ka hilinaʻi o ka ʻōnaehana, a kūpono hoʻi no ka mana kaʻina hana a me nā ʻōnaehana hana nui.

S7-1200 moʻo
ʻO ka moʻo S7-1200 he PLC hou mai Siemens, kūpono i nā hana automation liʻiliʻi a me ka liʻiliʻi. Hoʻohana kēia pūʻulu PLC i kahi hoʻolālā modular streamlined, e hōʻemi ana i nā kumukūʻai a me nā pilikia mālama. Kākoʻo ka moʻo S7-1200 i ke kaiapuni hoʻolālā TIA Portal, maʻalahi ka papahana a me ka hoʻokele. I ka manawa like, hoʻohui ia i kahi interface Ethernet, kākoʻo i ke kamaʻilio PROFINET, a loaʻa iā ia nā mana kamaʻilio ikaika. Kākoʻo pū ka moʻo S7-1200 i nā ʻano modula I/O like ʻole, he scalability maikaʻi, a hoʻololi i nā pono automation like ʻole. ʻO kona hilinaʻi kiʻekiʻe a me nā mana hana paʻa e hana i ka S7-1200 series i kahi koho kūpono no nā papahana automation liʻiliʻi a me ka nui.

S7-1500 moʻo
ʻO ka moʻo S7-1500 he PLC hana kiʻekiʻe mai Siemens, kūpono no nā hana automation paʻakikī a koi. Ke hoʻohana nei kēia pūʻulu PLC i nā kaʻina hana kiʻekiʻe a kākoʻo i nā polokalamu kiʻekiʻe a me nā hana diagnostic. Hoʻohui ka S7-1500 i nā pilina Ethernet, kākoʻo i nā hana kamaʻilio PROFINET kiʻekiʻe, a loaʻa iā ia nā modula hana waiwai a me nā mana hana ikaika. I ka manawa like, hāʻawi ia i ka redundancy a me ka loaʻa kiʻekiʻe o nā hoʻonā e hōʻoia i ka paʻa a me ka hilinaʻi o ka ʻōnaehana. Kākoʻo pū ka S7-1500 series i nā ʻano modula I/O a me nā modula kamaʻilio, a hiki iā ʻoe ke koho i nā modula kūpono a me nā pilina pūnaewele e like me nā pono kikoʻī. ʻO kāna hana kiʻekiʻe a me ka maʻalahi e hana i ka moʻo S7-1500 i koho mua no nā papahana ʻoihana ʻoihana kiʻekiʻe.

PLC paakiki a me PLC palupalu
Me ka hoʻomohala ʻana o ka ʻenehana, ua hoʻololi ʻia ka PLC mai ka hilinaʻi ʻana i ka ʻenehana a hiki i ka wehewehe ʻana i nā polokalamu, e hopena i ʻelua mau ʻano o ka PLC paʻakikī a me ka PLC palupalu. Ma ke ʻano he alakaʻi i ke kahua o ka automation, hoʻohana nui ʻia ʻo Siemens 'hard PLC a me nā huahana PLC palupalu. ʻO nā PLC paʻakikī, e like me ka S7-1500 series, aia i nā lako paʻa i hoʻolaʻa ʻia a me nā polokalamu paʻa, a ua hoʻolālā ʻia no nā wahi ʻenehana kūikawā a me nā noi, me nā mea maikaʻi o ke kūpaʻa a me ka hana manawa maoli. ʻO nā PLC palupalu, e like me Siemens Simatic WinAC, e hoʻokō i nā hana PLC e pili ana i ka ʻenehana maʻamau (e like me PC) a me nā lako polokalamu, a loaʻa iā ia nā pōmaikaʻi o ka maʻalahi a me ka scalability. ʻOi aku ka maikaʻi o nā PLC paʻakikī no nā manawa me nā koi kiʻekiʻe loa no ka paʻa a me ka hana manawa maoli, ʻoiai nā PLC palupalu e kūpono i nā noi e koi ana i ka loli kiʻekiʻe a me ka scalability.
