PLC yog hais txog programmable logic controller, uas yog tshwj xeeb tshaj yog nyob rau hauv automation. Cov hauv qab no qhia txog hom kev ua yuam kev thiab kho cov txheej txheem thaum siv PLC.
Hom kev ua yuam kev hauv PLC (Programmable Logic Controller) suav nrog:
1. Kev ua yuam kev: PLC qhov kev zov me nyuam tau sau tsis raug lossis muaj cov lus qhia tsis raug lees paub, ua rau kev ua haujlwm yuam kev.
2. Hardware tsis ua hauj lwm: PLC khoom nws tus kheej muaj teeb meem, xws li I/O module tsis ua hauj lwm, CPU abnormality, thiab lwm yam.
3. Kev cuam tshuam hluav taws xob: PLC teeb liab cuam tshuam los ntawm yam xws li tsis tshua muaj hluav taws xob, luv Circuit Court, lossis inductance, ua rau PLC tsis tuaj yeem ua haujlwm zoo.
Rau ntau hom kev ua yuam kev, cov txheej txheem kho yog raws li hauv qab no:
1. Kev ua yuam kev: Xyuas seb PLC qhov kev pab cuam sau raug thiab nrhiav qhov ua yuam kev hauv qhov program. Nyob rau tib lub sijhawm, xyuas kom meej tias I / O cov cuab yeej txuas tau zoo thiab qhov ntsuas qhov ntsuas tau raug, kom ntseeg tau tias muaj kev sib raug zoo thiab kev ruaj ntseg ntawm qhov kev zov me nyuam.
2. Kho vajtse tsis ua haujlwm: Tshawb xyuas seb cov khoom siv PLC puas ua haujlwm zoo, txheeb xyuas cov khoom tsis raug, thiab hloov lossis kho lawv.
3. Kev cuam tshuam hluav taws xob: Txhim kho cov cuab yeej lossis cov kev sim ntsuas xws li cov lim dej thiab cov khoom sib cais kom tsis txhob cuam tshuam, txheeb xyuas qhov chaw ntawm hluav taws xob tsis raug, thiab ua haujlwm kho lossis kho.
Tsis tas li ntawd, hauv kev siv txhua hnub ntawm PLC, cov txheej txheem hauv qab no tuaj yeem siv los tiv thaiv qhov tsis raug tshwm sim:
1. Khaws PLC software hloov tshiab: Los ntawm kev siv software hloov tshiab cov kev pab cuam, qhov tsis zoo nyob rau hauv cov kev pab cuam uas twb muaj lawm lossis cov ntaub ntawv yuav raug zam, tswj kev ncaj ncees thiab kev ncaj ncees ntawm lub cev sab hauv.
2. Tsim cov txheej txheem kev khiav hauj lwm kom raug: Ua kom muaj qhov raug thiab ua qauv ntawm PLC kev ua haujlwm, thiab zam kev ua yuam kev uas yuav ua rau cov khoom siv sib tsoo.
3. Kev saib xyuas tsis tu ncua: Kev tshuaj xyuas tsis tu ncua thiab tswj cov khoom siv PLC kom ntseeg tau tias nws txoj haujlwm zoo thiab kev ncaj ncees. Nyob rau hauv cov txheej txheem ntawm kev tu cov cuab yeej, kev tiv thaiv kev saib xyuas thiab kev kwv yees kev saib xyuas yuav siv tau los tiv thaiv cov cuab yeej ua tsis tiav.
