合理布置硬布線輸入/輸出量
為了最大限度地減少DCS不同I/O站之間的數(shù)據(jù)交換,必須對(duì)硬布線輸入/輸出進(jìn)行科學(xué)合理的更改和布置,防止因傳輸負(fù)荷過(guò)大造成信息傳輸堵塞,使DCS通訊系統(tǒng)出現(xiàn)信息傳輸不及時(shí)、不準(zhǔn)確等異常現(xiàn)象。AUYBUS PROFIBUS DP-V1
03 加強(qiáng)培訓(xùn),規(guī)范操作規(guī)程
在進(jìn)行DS系統(tǒng)維護(hù)時(shí)要規(guī)范操作規(guī)程,因?yàn)橐恍┕ぷ鞔嬖诘陌踩[患較大,相關(guān)工作人員要經(jīng)過(guò)相關(guān)工作經(jīng)驗(yàn)的培訓(xùn),防止因人為因素導(dǎo)致DCS通訊故障。
例如卸載系統(tǒng)中應(yīng)用軟件、更改控制參數(shù)以及修改人機(jī)界面時(shí),要嚴(yán)格按照相關(guān)規(guī)章操作,能夠有效較低DCS系統(tǒng)發(fā)生故障的可能性。
04 保證沒(méi)有電磁干擾源
電磁干擾會(huì)影響DCS系統(tǒng)的穩(wěn)定性和可靠性,因此在DCS系統(tǒng)周圍要保證沒(méi)有電磁干擾源。在機(jī)柜室內(nèi)嚴(yán)禁使用對(duì)講機(jī)、手機(jī)以及平板電腦等能夠產(chǎn)生電磁波的儀器設(shè)備,以避免產(chǎn)生干擾信號(hào),造成系統(tǒng)銅通訊故障。
05 嚴(yán)格設(shè)計(jì)控制器及通訊網(wǎng)絡(luò)負(fù)荷PROFIBUS DP-V1使用教程
在設(shè)計(jì)階段要嚴(yán)格計(jì)算和規(guī)范DCS控制器工作負(fù)荷,還要仔細(xì)核算通訊網(wǎng)絡(luò)負(fù)荷,在設(shè)計(jì)變更時(shí),要考慮到I/O點(diǎn)的冗余以及報(bào)警數(shù)量等。同時(shí)在正式運(yùn)行該系統(tǒng)前要進(jìn)行調(diào)試和試運(yùn)行,模擬可能會(huì)發(fā)生的各種緊急情況,及時(shí)發(fā)現(xiàn)其存在的通訊故障,防止運(yùn)行后造成不必要的經(jīng)濟(jì)損失。
06 建立科學(xué)合理的DCS維護(hù)管理系統(tǒng)
DCS維護(hù)人員應(yīng)每天按時(shí)檢查DCS機(jī)柜和通信網(wǎng)絡(luò)各模塊的工作狀態(tài),檢查是否發(fā)生故障提示,并及時(shí)分析產(chǎn)生異常情況的原因,并且及時(shí)進(jìn)行處理。
market at present. 3、 Introduction to HMI engineering screen 3.1 operation screen
The operation screen is mainly divided into two parts: front and back, corresponding to two devices respectively, so the parameters are also corresponding to the left and right. The screen shows the real-time position, real-time frequency and current working mode of the current reciprocating machine. The program allows the equipment to modify the upper / lower limit of travel, delay and frequency during movement. Every time the manual / automatic mode is switched, the equipment will automatically return to the original point and wait for the command. The positive and negative linkage buttons at the bottom of the screen are used to turn on / off the linkage mode of the two devices. When the linkage mode is turned on, the two devices work synchronously. 3.2 recipe screen the recipe screen provides ten groups of recipes for customers to use. Select the
