Siemens PLC Product Overview

Zambiri za Siemens PLC Series Products
Monga mtsogoleri pagawo la automation, Siemens ali ndi mbiri yabwino padziko lonse lapansi chifukwa cha mapulogalamu ake owongolera (PLC). Monga gawo lalikulu la makina opanga makina, PLC imagwira ntchito zofunika kuwongolera, kuyang'anira ndi kukonza deta. Ndi magwiridwe ake apamwamba, kudalirika kwakukulu komanso mawonekedwe osiyanasiyana ogwiritsira ntchito, mndandanda wa Nokia PLC wakhala chisankho choyamba pama projekiti ambiri opanga makina. Nkhaniyi ifotokoza zazinthu zisanu zazikulu za Siemens PLC mwatsatanetsatane: S7-200 Smart, S7-300 (yosiya), S7-400, S7-1200 ndi S7-1500.

S7-200 Smart Series
Mndandanda wa S7-200 Smart ndiye compact PLC yaposachedwa kwambiri yomwe idakhazikitsidwa ndi Nokia, yopangidwira makina ang'onoang'ono odzichitira. Mndandanda wa PLCs umagwiritsa ntchito purosesa yothamanga kwambiri yokhala ndi mphamvu zowongolera komanso kukonza deta. Kukula kwake kochepa kumapangitsa kuti ikhale yoyenera nthawi zokhala ndi malo ochepa. Imathandizanso ma modules osiyanasiyana owonjezera, kuphatikizapo ma modules a digito a I / O, ma modules a analog I / O ndi ma modules otentha, omwe amatha kukulitsidwa mpaka ma modules 14. Mndandanda wa S7-200 Smart uli ndi mawonekedwe a Efaneti omangidwira ndipo umathandizira njira zoyankhulirana monga TCP/IP ndi Modbus TCP, zomwe ndizosavuta kupanga mapulogalamu ndi kulumikizana ndi netiweki. Kuphatikiza apo, imathandiziranso ma protocol angapo olankhulirana, monga RS485, RS232, etc., ndipo ili ndi ntchito zolumikizirana zamphamvu. Mndandanda wa PLC uwu umagwiritsa ntchito mapangidwe a mafakitale, umagwirizana ndi malo ovuta, ali ndi mphamvu zotsutsana ndi kusokoneza, ndipo amaonetsetsa kuti dongosololi likugwira ntchito mokhazikika.

Nokia PLC S7-200 SMART mndandanda
Zochita zazikulu (potengera mtundu wa V2.3 monga chitsanzo):
Perekani mitundu yosiyanasiyana ya ma CPU, monga CPU SR20, CPU ST20, CPU SR30, etc.
Makulidwe onse amalumikizana ngati 100mm m'lifupi ndi 81mm kuya, koma kutalika kumasiyanasiyana kutengera mtundu.
Malo osungiramo ogwiritsira ntchito amaphatikizapo malo osungiramo mapulogalamu, malo osungiramo deta ndi malo osungiramo, ndipo mphamvu imasiyanasiyana malinga ndi chitsanzo cha CPU.
Chiwerengero cha ma I/O a digito pamakinawa chimasiyana malinga ndi mtundu wa CPU. Mwachitsanzo, CPU SR20 ili ndi zolowetsa 12/8.

Chiwerengero cha mfundo zolowetsa ndi mfundo zotulutsa zimasiyanasiyana malinga ndi mtundu wa module. Mwachitsanzo, gawo lolowera digito la SM321 lili ndi mfundo 16, mfundo 32 ndi zina.

Zithunzi za S7-400
Mndandanda wa S7-400 ndi PLC yayikulu ya Siemens, yoyenera machitidwe ovuta komanso akuluakulu opangira makina. Mndandanda wa PLCs umagwiritsa ntchito mapurosesa apamwamba kwambiri omwe ali ndi mphamvu zowonongeka komanso odalirika kwambiri. Mndandanda wa S7-400 umathandizira ma modules osiyanasiyana owonjezera, kuphatikizapo ma modules owonjezera komanso olekerera zolakwika, kuti akwaniritse zofunikira zowongolera zovuta. Panthawi imodzimodziyo, imathandizira maukonde a mafakitale monga PROFINET ndi PROFIBUS, ndipo ali ndi ntchito zolankhulana zamphamvu. Mndandanda wa S7-400 ulinso ndi ntchito zolephera komanso zowonongeka kuti zitsimikizire kuti dongosololi ndi lokhazikika komanso lodalirika, ndipo ndiloyenera kuwongolera ndondomeko ndi machitidwe akuluakulu opanga zinthu.

Zithunzi za S7-1200
Mndandanda wa S7-1200 ndi PLC yatsopano yapakatikati yochokera ku Siemens, yoyenera ntchito zazing'ono komanso zapakatikati. Mndandanda wa PLCs uwu umagwiritsa ntchito mapangidwe osinthika, omwe amachepetsa ndalama ndi zovuta kukonza. Mndandanda wa S7-1200 umathandizira malo opangira mapulogalamu a TIA Portal, omwe ndi osavuta kukonza ndikuwongolera. Panthawi imodzimodziyo, imagwirizanitsa mawonekedwe a Ethernet, imathandizira kulankhulana kwa PROFINET, ndipo ili ndi mphamvu zolankhulana zamphamvu. Mndandanda wa S7-1200 umathandiziranso ma modules osiyanasiyana a I / O, ali ndi scalability yabwino, ndipo amasintha malinga ndi zosowa zosiyanasiyana. Kudalirika kwake kwakukulu komanso kukhazikika kwa magwiridwe antchito kumapangitsa mndandanda wa S7-1200 kukhala chisankho choyenera pama projekiti ang'onoang'ono ndi apakatikati.

Zithunzi za S7-1500
Mndandanda wa S7-1500 ndi PLC yogwira ntchito kwambiri kuchokera ku Siemens, yoyenera ntchito zovuta komanso zovuta zodzipangira. Mndandanda wa PLCs umagwiritsa ntchito mapurosesa apamwamba kwambiri ndipo umathandizira mapulogalamu apamwamba ndi ntchito zowunikira. Mndandanda wa S7-1500 umagwirizanitsa mawonekedwe a Ethernet, umathandizira ntchito zoyankhulirana zapamwamba za PROFINET, ndipo uli ndi ma modules olemera ogwira ntchito komanso mphamvu zopangira mphamvu. Panthawi imodzimodziyo, imapereka njira zowonongeka komanso zopezeka kwambiri kuti zitsimikizire kuti dongosololi ndi lokhazikika komanso lodalirika. Mndandanda wa S7-1500 umathandizanso ma modules osiyanasiyana a I / O ndi ma modules oyankhulana, ndipo mukhoza kusankha ma modules oyenerera ndi maukonde ogwirizana malinga ndi zosowa zenizeni. Kuchita kwake kwapamwamba komanso kusinthasintha kumapangitsa mndandanda wa S7-1500 kukhala woyamba kusankha mapulojekiti opangidwa ndi mafakitale ofunikira kwambiri.

Hard PLC ndi Soft PLC
Ndi chitukuko chaukadaulo, PLC yasintha kuchoka ku kudalira kwa hardware kupita ku tanthauzo la mapulogalamu, zomwe zidapangitsa kuti pakhale mitundu iwiri ya PLC yolimba ndi PLC yofewa. Monga mtsogoleri pankhani ya automation, Nokia 'hard PLC ndi zofewa za PLC zimagwiritsidwa ntchito kwambiri. Ma PLC olimba, monga mndandanda wa S7-1500, ali ndi zida zodzipatulira ndi mapulogalamu osasunthika, ndipo amapangidwira malo enieni a mafakitale ndi ntchito, ndi ubwino wokhazikika komanso nthawi yeniyeni. Ma Soft PLC, monga Siemens Simatic WinAC, amagwiritsa ntchito ntchito za PLC kutengera ma hardware wamba (monga PC) ndi mapulogalamu, ndipo ali ndi maubwino osinthika komanso osavuta. Ma PLC olimba ndi abwino kwambiri pamisonkhano yokhala ndi zofunikira kwambiri pakukhazikika komanso magwiridwe antchito anthawi yeniyeni, pomwe ma PLC ofewa ndi oyenera kugwiritsa ntchito zomwe zimafuna kusinthasintha kwakukulu komanso kusinthika.
