 一般來講，控制系統網絡可分為3層：信息層、控制層和設備層(傳感/執行層)。傳統的控制系統在信息層大都采用以太網，而在控制層和設備層一般采用不同的現場總線或其他專用網絡。目前，以太網已經滲透到了控制層和設備層，很多的PLC和遠程I/O供應商都能提供支持TCP/IP的以太網接口的產品。以太網之所以給自動化市場帶來風暴式的革命，主要有3個原因：低成本的刺激和速度的提高；現代企業對實時生產信息有越來越多的要求；以太網的開放性和兼容性。
    早期的以太網，多節點共享同一個傳輸媒體，稱為共享以太網(Shared Ethernet)，節點間通信采用廣播方式，易發生沖突。共享以太網用CSMA/CD技術來避免沖突，即發送方檢測到沖突就暫停發送，隨機延遲一段時間后再重新發送直到成功。由于延遲時間是隨機的，不能事先知道，因而共享以太網的時間響應具有不確定性，不能用于強實時性場合。
    交換以太網(Switched Ethernet)的出現克服了這一缺點，以太網的交換機(Switch)是數據鏈路層(ISO/OSI參考模型第二層)的多端口網橋，也可以說是智能分配器。交換機將其管理的網絡以星型拓撲結構劃分為許多物理上互相隔離而邏輯上互相聯系的節點，每一節點單獨與交換機建立物理連接，在通信的時候交換機會在發送端口與接受端口間建立一個獨占的全雙工通道，它具有以太網的全部帶寬并避免沖突。
