控制系統一般設計步驟

（2）    確定 I/O 設備

根據被控對象對 PLC 控制系統的功能要求，確定系統所需的用戶輸入、輸出設備。常用的輸入設備有按鈕、選擇開關、行程開關、傳感器等，常用的輸出設備有繼電器、接觸器、指示燈、電磁閥等。

（3）    選擇合適的 PLC 類型

根據已確定的用戶 I/O 設備，統計所需的輸入信號和輸出信號的點數，選擇合適的 PLC 類型，包括機型的選擇、容量的選擇、 I/O 模塊的選擇、電源模塊的選擇等。

（4）    分配 I/O 點

分配 PLC 的輸入輸出點，編制出輸入 / 輸出分配表或者畫出輸入 / 輸出端子的接線圖。接著九可以進行 PLC程序設計，同時可進行控制柜或操作臺的設計和現場施工。

（5）    設計應用系統梯形圖程序

根據工作功能圖表或狀態流程圖等設計出梯形圖即編程。這一步是整個應用系統設計的zui核心工作，也是比較困難的一步，要設計好梯形圖，首先要十分熟悉控制要求，同時還要有一定的電氣設計的實踐經驗。

（6）    將程序輸入 PLC

當使用簡易編程器將程序輸入 PLC 時，需要先將梯形圖轉換成指令助記符，以便輸入。當使用可編程序控制器的輔助編程軟件在計算機上編程時，可通過上下位機的連接電纜將程序下載到 PLC 中去。

（7）    進行軟件測試

程序輸入 PLC 后，應*行測試工作。因為在程序設計過程中，難免會有疏漏的地方。因此在將 PLC 連接到現場設備上去之前，必需進行軟件測試，以排除程序中的錯誤，同時也為整體調試打好基礎，縮短整體調試的周期。

（8）    應用系統整體調試

在 PLC 軟硬件設計和控制柜及現場施工完成后，就可以進行整個系統的聯機調試，如果控制系統是由幾個部分組成，則應先作局部調試，然后再進行整體調試；如果控制程序的步序較多，則可*行分段調試，然后再連接起來總調。調試中發現的問題，要逐一排除，直至調試成功。
