Qee qhov loj qhov sib txawv ntawm a SIS , PLC thiab BPCS hardware yog: Standard BPCS muaj hom tsis ua hauj lwm hom. a SIS PLC yuav ua tsis tau zoo nyob rau hauv ib qho kev tshwm sim (SIL) a SIS PLC tau ntawv pov thawj rau cov qauv zoo li IEC61508 rau kev siv hauv a daim ntawv thov kev nyab xeeb.

Tsuas yog li ntawd, dab tsi yog kev tswj hwm qhov system?

Kev nyab xeeb ua haujlwm qhov system ( SIS ) muaj ib tug engineered txheej hardware thiab software tswj uas tshwj xeeb tshaj yog siv rau cov txheej txheem tseem ceeb tshuab.

Ib yam li ntawd, sil3 yog dab tsi? SIB 3 yog ib qib kev nyab xeeb kev nyab xeeb tau teev tseg los ntawm IEC 61508 tus qauv. Nws tau txhais los ntawm kev txo qis kev pheej hmoo ntawm 1.000-10.000 ntawm kev ua tsis tiav ntawm kev thov thiab 10-8-10-7 rau qhov yuav tshwm sim ntawm kev ua tsis tiav ib teev. SIB 3 yog qib kev ruaj ntseg siab tshaj plaws uas muaj peev xwm ua tau rau kev lag luam feem ntau.

Tib neeg tseem nug, tus sis hauv kev ntsuas yog dab tsi?

Kev ruaj ntseg Instrumented System ( SIS ) yog cov txheej txheem tsim los ntawm cov ntsuas hluav taws xob, kev daws teeb meem logic thiab kev tswj hwm zaum kawg tsim thiab teeb tsa los tiv thaiv cov neeg ua haujlwm, khoom siv thiab ib puag ncig los ntawm kev ua cov txheej txheem rau lub xeev muaj kev nyab xeeb. Kev Nyab Xeeb Kev Nyab Xeeb ( SIS ) | instrumentationportal.com.

Qhov txawv ntawm PLC thiab kev nyab xeeb PLC yog dab tsi?

A kev nyab xeeb programmable logic maub los ( PLC ) zoo li tus qauv PLC . Nws tuaj yeem siv los tswj thiab automate tej khoom ntawm cov khoom siv. A kev nyab xeeb PLC txhawb txhua daim ntawv thov uas tus qauv PLC ua; txawm li cas los, a kev nyab xeeb PLC muaj kev sib xyaw ua ke kev nyab xeeb cov haujlwm uas tso cai rau nws los tswj kev nyab xeeb systems thiab.
