Kutheni le nto iPLC yenziwe yacaba?
2023-12-08
Ngokuncitshiswa okuqhubekayo kwamaxabiso e-PLC kunye nokwandiswa kwemfuno yabasebenzisi, ngakumbi nangakumbi izixhobo ezincinci kunye neziphakathi zaqala ukukhetha i-PLC yokulawula, ukusetyenziswa kwe-PLC e-China kukhula ngokukhawuleza okukhulu. Ngophuhliso olukhawulezayo loqoqosho lwaseTshayina kunye nokuphuculwa okuqhubekayo kwinqanaba le-automation yasekhaya, i-PLC yase-China kwixesha elizayo iya kubambelela kwisantya sokukhula ngokukhawuleza. Iimveliso zanamhlanje ze-PLC zinokwahlulwa zibe zizikolo ezithathu eziphambili: i-United States, iYurophu kunye nomlomo wale nto. Ngophuhliso olukhawulezayo lwePLC yaseTshayina, iPLC yasekhaya ithatha ubunzima obuninzi. Ngokwezibalo, ngaphezu kwe-95% yezinga lokungaphumeleli kwezi mveliso ze-PLC zivela kubonelelo lwamandla, ukuhanjiswa, izibuko zonxibelelwano kwezi ndawo. Ke indlela yokunciphisa izinga lokusilela kwezi ndawo iGu Mei PLC yenze olu tshintsho. Unikezelo lwamandla lwangaphandle ukuphelisa i-90% yokusilela Ukuthintela utshintsho lobushushu bomoya, utshintsho lomswakama phantsi kwefuthe lomoya, uthuli, ukukhanya kwe-ultraviolet kunye nezinye izinto zokonakalisa izixhobo. Eyona nto ithanda ukusilela ngokubanzi kwinkqubo yonikezelo lwamandla kunye nenkqubo yenethiwekhi yonxibelelwano, unikezelo lwamandla kumsebenzi oqhubekayo, ukutshatyalaliswa kobushushu, umbane kunye nokuguquguquka kwangoku kwimpembelelo ayinakuphepheka. Unxibelelwano kunye nothungelwano ngokunokwenzeka kokuphazamiseka kwangaphandle, indawo yangaphandle yenye yezona zinto zinkulu ezibangela ukungaphumeleli kwezixhobo zangaphandle zonxibelelwano. Okwangoku, i-PLC kwimarike isisiseko sombane esakhelwe ngaphakathi, ngelixa iimveliso zethu zisebenzisa amandla angaphandle ukuphelisa i-90% yokusilela. Ukuhanjiswa ngenye yeebrendi ezilungileyo kakhulu - uOmron Ulawulo lweendleko zoshishino lwe-PLC, ukhetho luxhomekeke kwi-I / O, i-modyuli ye-I / O yinxalenye ebalulekileyo ye-PLC. elona khonkco libuthathaka le-PLC kwizibuko le-I/O. inzuzo yobugcisa ye-PLC lizibuko layo le-I/O, kwimeko yenqanaba lobugcisa lenkqubo yokusingatha umahluko phakathi kokungabikho komatshini, imodyuli ye-I/O licandelo eliphambili elibonisa ukusebenza kwe-PLC, ngoko kunjalo kwakhona. ikhonkco elibalaseleyo kumonakalo we-PLC. Ireyiyi esetyenziswa nguGumei nguOmron, yenye yeebrendi ezilishumi eziphezulu kwihlabathi. Ukhuseleko olukhethekileyo lwezibuko lonxibelelwano Ireyithi ye-RS-232 yokuhanjiswa kwedatha iphantsi, umgama wothumelo ulinganiselwe, kwaye amandla okuchasana nokuphazamiseka akubi. I-RS-422 ithatha imowudi yonxibelelwano oluyi-duplex epheleleyo kunye nokuhanjiswa okungafaniyo, kunye nokukwazi ukuphazamiseka kwemowudi ye-anticommon kuphuculwe. I-GuMei isebenzise i-485 port, i-485 port kune-232 i-port resistance resistance iphezulu, akukho lula ukutshisa. Ngezi ndlela, izinga lokungaphumeleli kwe-PLC liyancipha kakhulu, kwaye umthamo we-PLC uhlangene ngakumbi kodwa usebenza ngcono, ezi zicelo kumthengi zihlala zifumana imvume yomthengi.
