內部輔助繼電器不對外輸出，不能直接連接外部器件，而是在控制其他繼電器、定時器、計數器時作數據存儲或數據處理用。根據程序設計的需要，應合理安排PLC的內部輔助繼電器，在設計說明書中應詳細列出各內部輔助繼電器在程序中的用途，避免重復使用。
3．分配定時器計數器
對用到定時器和計數器的控制系統，注意定時器和計數器的編號不能相同。若掃描時間較長，則要使用高速定時器以保證計時準確
安全回路設計
安全回路起保護人身安全和設備安全的作用，它應能獨立于PLC工作，并采用非半導體的機電元件以硬接線方式構成。
確保系統安全的硬接線邏輯回路，在以下幾種情況下將發揮安全保護作用：① PLC或機電元件檢測到設備發生緊急異常狀態時；② PLC失控時；③ 操作人員需要緊急干預時。
設計安全回路的任務包括以下內容：
(1) 確定控制回路之間邏輯和操作上的互鎖關系；
(2) 設計硬回路以提供對過程中重要設備的手動安全性干預手段；
(3) 為PLC定義故障形式和重新啟動特性。
PLC應用系統的軟件設計
PLC應用軟件設計的內容
PLC應用軟件的設計是一項十分復雜的工作，它要求設計人員既要有PLC、計算機程序設計的基礎，又要有自動控制的技術，還要有一定的現場實踐經驗。
一個實用的PLC軟件工程的設計通常要涉及以下幾個方面的內容：
(1) PLC軟件功能的分析與設計；
(2) IO信號及數據結構分析與設計(3) 程序結構分析與設計；
(4) 軟件設計規格說明書編制；
(5) 用編程語言、PLC指令進行程序設計；
(6) 軟件測試；
(7) 程序使用說明書編制。
PLC應用系統的軟件設計步驟
根據可編程序控制器系統硬件結構和生產工藝要求，在軟件規格說明書的基礎上，編制實際應用程序并形成程序說明書的過程就是應用系統的軟件設計。
