傳統(tǒng)的繼電器控制系統(tǒng)中使用了大量的中間繼電器、時間繼電器。由于觸點(diǎn)接觸不良，容易出現(xiàn)故障。PLC用軟件代替大量的中間繼電器和時間繼電器，僅剩下與輸入和輸出有關(guān)的少量硬件元件，接線可減少到繼電器控制系統(tǒng)的十分之一到百分之一，因觸點(diǎn)接觸不良造成的故障大為減少。
PLC使用了一系列硬件和軟件抗干擾措施，具有很強(qiáng)的抗干擾能力，平均無故障時間達(dá)到數(shù)萬小時以上，可以直接用于有強(qiáng)烈干擾的工業(yè)生產(chǎn)現(xiàn)場，PLC大用戶公認(rèn)為最可靠的工業(yè)控制設(shè)備之一。 PLC用軟件功能取代了繼電器控制系統(tǒng)中大量的中間繼電器、時間繼電器、計數(shù)器等器件，使控制柜的設(shè)計、安裝、接線工作量大大減少。 PLC的梯形圖程序可以用順序控制設(shè)計法來設(shè)計。這種編程方法很有規(guī)律，很容易掌握。對于復(fù)雜的控制系統(tǒng)，如果掌握了正確的設(shè)計方法，設(shè)計梯形圖的時間比設(shè)計繼電器系統(tǒng)電路圖的時間要少得多。
可以在實驗室模擬調(diào)試PLC的用戶程序，輸入信號用小開關(guān)來模擬，可通過PLC發(fā)光二極管觀察輸出信號的狀態(tài)。完成了系統(tǒng)的安裝和接線后，在現(xiàn)場的統(tǒng)調(diào)過程中發(fā)現(xiàn)的問題一般通過修改程序就可以解決，系統(tǒng)的調(diào)試時間比繼電器系統(tǒng)少得多。
First, the development of PLC network technology, which has two trends: on the one hand, PLC network system is no longer a self-contained closed system, but rapidly develops to an open system. In addition to bing their own unique PLC network system to complete equipment control tasks, major brands of PLC can also network with the upper computer management system to realize inbation exchange, Become a part of the whole inbation management system; On the other hand, fieldbus technology has been widely used. PLC and other inbligent equipment installed on the site, such as inbligent instruments, sensors, inbligent solenoid valves, inbligent drive actuators, etc, It is connected through a transmission medium (such as twisted pair, coaxial cable and optical cable) and transmits inbation to each other according to the same communication protocol, so as to b a field industrial control network. Compared with a simple PLC remote network, this network has more flexible configuration, more convenient capacity expansion, lower cost, better perbance price ratio and more open significance.
