PLC主要功能 (1)邏輯控制功能。 (2)信號採集功能。 (3)輸出控制功能。 (4)數據處理功能。 (5)定時計數功能。 (6)遠程I/O功能。 (7)人機界面功能(HMI)。 (8)故障自診斷功能。 (9)通信聯網功能。 (10)實時通信和冗餘互備功能。
PLC主要有以下特點: 1.可靠性高 PLC用軟件代替繼電器控制係統中大量的中間繼電器和時間繼電器,接線可以減少到繼電器控制係統的十分之一以下,大大減少了觸點接觸不良的可能性。 2.抗幹擾能力強 I/O設計具有完善的通道保護和多種形式的濾波電路,以抑止高頻幹擾,削弱各模塊之間的幹擾影響。在係統的輸入/輸出回路中,採用光電隔離等措施可有效防止回路間的信號幹擾。 3.編程簡單、係統設計修改調試方便 PLC採用軟件方法取代繼電器控制係統中大量的中間繼電器、時間繼電器、計數器等器件,使控制櫃的設計、安裝、接線大大簡化。 4.模塊化結構、通用性強,維護簡單、維修方便 PLC產品係列化、標準化、模塊化,用戶可根據實際需求靈活選擇,無需用戶自己再進行設計和****硬件裝置。
PLC作為交付復雜的工業流程,鋼鐵行業的控制係統一般較大,經常多達數千點,小規模的子係統也在數百點。即主要是大中型PLC的市場。當然也有部分輔助機械或者小型係統會用到小型PLC,但比例極低只有將近2%,不能進入考量這個行業的戰略視線。
