PLC控制系統(tǒng)設計包括硬件設計和軟件設計。

　　1.PLC控制系統(tǒng)的硬件設計

　　硬件設計是PLC控制系統(tǒng)的至關重要的一個環(huán)節(jié)，這關系著PLC控制系統(tǒng)運行的可靠性、安全性、穩(wěn)定性。主要包括輸入和輸出電路兩部分。

　　(1)PLC控制系統(tǒng)的輸入電路設計。PLC供電電源一般為AC85-240V，適應電源范圍較寬，但為了抗干擾，應加裝電源凈化元件(如電源濾波器、1：1隔離變壓器等);隔離變壓器也可以采用雙隔離技術，即變壓器的初、次級線圈屏蔽層與初級電氣中性點接大地，次級線圈屏蔽層接PLC輸入電路的地，以減小高低頻脈沖干擾。

　　PLC輸入電路電源一般應采用DC24V,同時其帶負載時要注意容量，并作好防短路措施，這對系統(tǒng)供電安全和PLC安全至關重要，因為該電源的過載或短路都將影響PLC的運行，一般選用電源的容量為輸入電路功率的兩倍，PLC輸入電路電源支路加裝適宜的熔絲，防止短路。

　　(2)PLC控制系統(tǒng)的輸出電路設計。依據(jù)生產工藝要求，各種指示燈、變頻器/數(shù)字直流調速器的啟動停止應采用晶體管輸出，它適應于高頻動作，并且響應時間短;如果PLC系統(tǒng)輸出頻率為每分鐘6次以下，應首選繼電器輸出，采用這種方法，輸出電路的設計簡單，抗干擾和帶負載能力強。

　　如果PLC輸出帶電磁線圈等感性負載，負載斷電時會對PLC的輸出造成浪涌電流的沖擊，為此，對直流感性負載應在其旁邊并接續(xù)流二極管，對交流感性負載應并接浪涌吸收電路，可有效保護PLC。

　　當PLC掃描頻率為10次/min以下時，既可以采用繼電器輸出方式，也可以采用PLC輸出驅動中間繼電器或者固態(tài)繼電器(SSR)，再驅動負載。

　　對于兩個重要輸出量，不僅在PLC內部互鎖，建議在PLC外部也進行硬件上的互鎖，以加強PLC系統(tǒng)運行的安全性、可靠性。

　　對于常見的AC220V交流開關類負載，例如交流接觸器、電磁閥等，應該通過DC24V微小型中間繼電器驅動，避免PLC的DO接點直接驅動，盡管PLC手冊標稱具有AC220V交流開關類負載驅動能力。

　　(3)PLC控制系統(tǒng)的抗干擾設計。隨著工業(yè)自動化技術的日新月異的發(fā)展，晶閘管可控整流和變頻調速裝置使用日益廣泛，這帶來了交流電網的污染，也給控制系統(tǒng)帶來了許多干擾問題，防干擾是PLC控制系統(tǒng)設計時必須考慮的問題。一般采用以下幾種方式：

　　隔離：由于電網中的高頻干擾主要是原副邊繞組之間的分布電容耦合而成，所以建議采用1：1超隔離變壓器，并將中性點經電容接地。

　　屏蔽：一般采用金屬外殼屏蔽，將PLC系統(tǒng)內置于金屬柜之內。金屬柜外殼可靠接地，能起到良好的靜電、磁場屏蔽作用，防止空間輻射干擾。

　　布線：強電動力線路、弱電信號線分開走線，并且要有一定的間隔;模擬信號傳輸線采用雙絞線屏蔽電纜。
