各部分的主要作用是:
輸入部分:收集并保存被控對(duì)象實(shí)際運(yùn)行的數(shù)據(jù)的信息(被控對(duì)象上的各種開關(guān)量信息或操作命令等)。
邏輯部分:處理輸入部分報(bào)取得的信息,并按照被控對(duì)象的實(shí)際動(dòng)作要求正確的反映。
輸出部分:提供正在被控制的裝置中,哪幾個(gè)設(shè)備需要實(shí)施操作處理。
用戶程序通過編程器或其它輸入設(shè)備輸入并存放在PLC的用戶存儲(chǔ)器中。當(dāng)PLC開始運(yùn)行時(shí),CPU根據(jù)系統(tǒng)監(jiān)控程序的規(guī)定順序,通過掃描,完成各輸入點(diǎn)的狀態(tài)采集或輸入數(shù)據(jù)采集、用戶程序的執(zhí)行、各輸出點(diǎn)狀態(tài)更新、編程器鍵入響應(yīng)和顯示更新及CPU自檢等功能。
PLC掃描既可按固定的程序進(jìn)行,也可按用戶程序規(guī)定的可變順序進(jìn)行。
PLC采用集中采樣、集中輸出的工作方式,減少了外界的干擾。
The main functions of each part are:
Input part: collect and save the inbation of the actual operation data of the controlled b (various switching value inbation or operation commands on the controlled b, etc.).
Logic part: process the inbation obtained from the b part and correctly reflect it according to the actual b requirements of the controlled b.
Output part: it provides which devices in the controlled device need to implement operation processing.
The user program is b by programmer or other b equipment and stored in the user memory of PLC. When the PLC starts running, the CPU completes the functions of status acquisition or b data acquisition of each b point, execution of user program, status update of each output point, programmer b response and display update, CPU self-test and so on through scanning according to the specified sequence of system monitoring program.PLC scanning can be carried out according to either fixed program or variable sequence specified by user program.PLC adopts the working mode of centralized sampling and centralized output to reduce external interference.
