內(nèi)部輔助繼電器不對(duì)外輸出，不能直接連接外部器件，而是在控制其他繼電器、定時(shí)器、計(jì)數(shù)器時(shí)作數(shù)據(jù)存儲(chǔ)或數(shù)據(jù)處理用。根據(jù)程序設(shè)計(jì)的需要，應(yīng)合理安排PLC的內(nèi)部輔助繼電器，在設(shè)計(jì)說明書中應(yīng)詳細(xì)列出各內(nèi)部輔助繼電器在程序中的用途，避免重復(fù)使用。
3．分配定時(shí)器計(jì)數(shù)器
對(duì)用到定時(shí)器和計(jì)數(shù)器的控制系統(tǒng)，注意定時(shí)器和計(jì)數(shù)器的編號(hào)不能相同。若掃描時(shí)間較長(zhǎng)，則要使用高速定時(shí)器以保證計(jì)時(shí)準(zhǔn)確
安全回路設(shè)計(jì)
安全回路起保護(hù)人身安全和設(shè)備安全的作用，它應(yīng)能獨(dú)立于PLC工作，并采用非半導(dǎo)體的機(jī)電元件以硬接線方式構(gòu)成。
確保系統(tǒng)安全的硬接線邏輯回路，在以下幾種情況下將發(fā)揮安全保護(hù)作用：① PLC或機(jī)電元件檢測(cè)到設(shè)備發(fā)生緊急異常狀態(tài)時(shí)；② PLC失控時(shí)；③ 操作人員需要緊急干預(yù)時(shí)。
設(shè)計(jì)安全回路的任務(wù)包括以下內(nèi)容：
(1) 確定控制回路之間邏輯和操作上的互鎖關(guān)系；
(2) 設(shè)計(jì)硬回路以提供對(duì)過程中重要設(shè)備的手動(dòng)安全性干預(yù)手段；
(3) 為PLC定義故障形式和重新啟動(dòng)特性。
PLC應(yīng)用系統(tǒng)的軟件設(shè)計(jì)
PLC應(yīng)用軟件設(shè)計(jì)的內(nèi)容
PLC應(yīng)用軟件的設(shè)計(jì)是一項(xiàng)十分復(fù)雜的工作，它要求設(shè)計(jì)人員既要有PLC、計(jì)算機(jī)程序設(shè)計(jì)的基礎(chǔ)，又要有自動(dòng)控制的技術(shù)，還要有一定的現(xiàn)場(chǎng)實(shí)踐經(jīng)驗(yàn)。
一個(gè)實(shí)用的PLC軟件工程的設(shè)計(jì)通常要涉及以下幾個(gè)方面的內(nèi)容：
(1) PLC軟件功能的分析與設(shè)計(jì)；
(2) IO信號(hào)及數(shù)據(jù)結(jié)構(gòu)分析與設(shè)計(jì)(3) 程序結(jié)構(gòu)分析與設(shè)計(jì)；
(4) 軟件設(shè)計(jì)規(guī)格說明書編制；
(5) 用編程語言、PLC指令進(jìn)行程序設(shè)計(jì)；
(6) 軟件測(cè)試；
(7) 程序使用說明書編制。
PLC應(yīng)用系統(tǒng)的軟件設(shè)計(jì)步驟
根據(jù)可編程序控制器系統(tǒng)硬件結(jié)構(gòu)和生產(chǎn)工藝要求，在軟件規(guī)格說明書的基礎(chǔ)上，編制實(shí)際應(yīng)用程序并形成程序說明書的過程就是應(yīng)用系統(tǒng)的軟件設(shè)計(jì)。
