產(chǎn)品詳情
操控功用包含PID操控運算、前饋賠償操控運算、比值操控運算等,應(yīng)依據(jù)操控請求斷定。PLC首要用于次序邏輯操控,因此,大大都場合常選用單回路或多回路操控器解決模仿量的操控,有時也選用專用的智能輸入輸出單元完結(jié)所需的操控功用,行進PLC的處理速度和節(jié)省存儲器容量。例如選用PID操控單元、高速計數(shù)器、帶速度賠償?shù)哪7聠卧?、ASC碼改換單元等。
(三)通訊功用
大中型PLC體系應(yīng)支撐多種現(xiàn)場總線和標準通訊協(xié)議(如TCP/IP),需求時應(yīng)能與工廠管理網(wǎng)(TCP/IP)相連接。通訊協(xié)議應(yīng)契合ISO/IEEE通訊標準,應(yīng)是敞開的通訊網(wǎng)絡(luò)。
PLC體系的通訊接口應(yīng)包含串行和并行通訊接口(RS2232C/422A/423/485)、RIO通訊口、工業(yè)以太網(wǎng)、常用DCS接口等;大中型PLC通訊總線(含接口設(shè)備和電纜)應(yīng)1:1冗余裝備,通訊總線應(yīng)契合國際標準,通訊間隔應(yīng)滿意設(shè)備實踐請求。
PLC體系的通訊網(wǎng)絡(luò)中,上級的網(wǎng)絡(luò)通訊速率應(yīng)大于1Mbps,通訊負荷不大于60%。PLC體系的通訊網(wǎng)絡(luò)首要辦法有下列幾種辦法:1)PC為主站,多臺同類型PLC為從站,構(gòu)成簡便PLC網(wǎng)絡(luò);2)1臺PLC為主站,別的同類型PLC為從站,構(gòu)成主從式PLC網(wǎng)絡(luò);3)PLC網(wǎng)絡(luò)經(jīng)過特定網(wǎng)絡(luò)接口連接到大型DCS中作為DCS的子網(wǎng);4)專用PLC網(wǎng)絡(luò)(各廠商的專用PLC通訊網(wǎng)絡(luò))。
為減輕CPU通訊使命,依據(jù)網(wǎng)絡(luò)構(gòu)成的實踐需求,應(yīng)挑選具有不一樣通訊功用的(如點對點、現(xiàn)場總線、工業(yè)以太網(wǎng))通訊處理器。
