PLC feem ntau yog lub rooj vag programmable array (FPGA), ARM, Intel, lossis microprocessor yooj yim. Hauv qee qhov kev siv high-end thiab nyuaj, cov neeg siv kuj siv lub PC Industrial ua PLC. Lub operating system feem ntau yog lub sijhawm ua haujlwm tiag tiag (RTOS) rau kev muab cov lus teb txiav txim siab mus rau ob peb microseconds. Cov software yuav tsum tau ua rau PLC muaj peev xwm los tuav IEC 61131-3 cov lus programming xws li tus ntaiv, cov lus raws li cov lus, thiab cov duab thaiv kev ua haujlwm.
Ntawm qhov tod tes, DCS yog qhov zoo tshaj plaws Industrial PC khiav lub hom phiaj kev ua haujlwm dav dav (GPOS) xws li Linux lossis Windows, yog li muab tsis muaj kev ua haujlwm ntawm lub sijhawm tiag tiag nrog lub sijhawm zoo tshaj plaws ntawm ib ncig ntawm ob peb milliseconds. Zoo li PLC, DCS kuj xav tau software uas cov kev pab cuam lossis teeb tsa lub kaw lus raws li tus neeg siv xav tau. Tsis tas li ntawd, ib qho DCS muab kev muaj peev xwm ntawm kev rov ua dua, thiab nyob ntawm qhov kev thuam ntawm cov ntawv thov raug daws; tus neeg siv tuaj yeem txiav txim siab los siv cov txheej txheem rov ua dua. Feem ntau, cov chaw tsim hluav taws xob yog qhov piv txwv zoo tshaj plaws ntawm cov txheej txheem tseem ceeb uas xav tau 24 * 7 ua haujlwm.
Muaj qhov sib txawv ntawm qhov kev xa tawm ntawm PLC lossis DCS, thiab nws nyob ntawm daim ntawv thov, lub sijhawm teb, kev ua haujlwm nyab xeeb, thiab hom kev tswj hwm xav tau. Lub PLC yog ib qho kev xaiv rau lub tshuab tswj thiab automation uas xav tau kev txiav txim siab, lub sij hawm teb ceev ceev, qhov DCS yog ib qho kev xaiv rau lub Hoobkas automation rau cov ntaub ntawv nrhiav tau, tsom xam, qhia, los yog ib tug txheej txheem thiab cog kev tswj ntawm lub tseem ceeb infrastructure.
