Ib lub twj tshaj tawm yog ib qho txuas tshwj xeeb siv los hloov cov cim, hluav taws xob, roj av, lossis kua los ntawm ib qhov chaw mus rau lwm qhov chaw. Nws qhov tseem ceeb tseem ceeb yog nws lub peev xwm kis tau los ntawm cov vaj tse, khoom siv hauv tsev, txhim kho cov cuab yeej sib txuas thaum muab cov qauv sib txuas thaum muab cov qauv sib txuas thaum muab kev sib txuas ntawm sab hauv thiab sab nraud. Cov txuas txuas no ua lub luag haujlwm tseem ceeb hauv ntau lub khoos kas xav tau kev sib khi, rho tawm, lossis cov qauv sib xyaw.
Ib qho kev tshaj tawm cov khoom siv hluav taws xob feem ntau yog qhov tsim ntawm lub vaj huam sib luag ntawm lub cuab yeej vaj tse lossis tswj lub thawv lossis flange rau kev ua kom tiav. Ob qho kawg ntawm lub txuas txuas yog pre {{1} Nruab nrog cov qauv txuas, xws li RJ45, USB, SMA, DB9, lossis M12. Cov neeg siv tau ncaj qha ntsaws thiab unplug cables tsis tas yuav tsum tau khiav lawv los ntawm ib qho chaw mus rau lwm qhov, yog li txhim kho cov zuag qhia tag nrho thiab kev ntseeg tau ntawm lub system.
Hauv cov kev siv tswv yim, cov khoom siv cov khoom siv tau siv dav hauv kev siv tshuab, kev sib txuas lus, ib qho khoom siv kho mob, ntsuas chaw kuaj cov khoom siv, thiab lwm thaj teb. Piv txwv li, hauv kev tswj cov tshuab tswj kev kho tshuab, RJ45 lossis USB cov khoom noj khoom haus tuaj yeem siv los qhia cov cim tswj sab nraud rau sab hauv PlC tswj. Hauv xov tooj cua ntau yam cuab yeej siv, SMA lossis BNC cov ntaub ntawv sib txuas ua kom muaj kev cuam tshuam kom tsis txhob muaj kev sib kis dawb} dawb Nyob rau hauv lub tshuab nqus tsev kuaj khoom, tshwj xeeb tsim muaj siab heev - Lub tshuab hluav taws xob cov khoom sib txuas hluav taws xob.
Zuag qhia tag nrho, cov ntawv tshaj tawm xov tooj tau muab cov qauv ruaj khov, muaj txiaj ntsig zoo rau kev xa cov paib lossis lub zog tsim nyog rau kev sib khi, kev tiv thaiv, lossis kev tiv thaiv lossis kev daws teeb meem. Lawv tsis tsuas yog txhim kho cov cuab yeej tu kom muaj kev tswj hwm tab sis kuj yooj yim los tsim qauv, ua rau lawv muaj kev sib txuas tsis tseem ceeb hauv cov tshuab niaj hnub no.
