工業領域的設備集成化、數字化、網絡化、智能化已是必然趨勢，“信息孤島”早已
不能適應當今的信息化，急需將現場設備的控制與數據采集網絡化，那么具有通信作用的智能節點是使設備網絡化的關鍵。CP2200 是工業領域最小的以太網控制器，它再與單片機相結合，便可實現以太網智能節點，來完成工業領域中現場數據采集與控制的任務。

Abstract：It is necessary trend that facility is integrated, digitized, networked and smarted in
industrial field. “Information-isolated-island” early don’t adapt to information of nowadays.
Control and data acquisition of field device is need urgently networking. So smart node carring communication role is key point of making device networked. CP2200 is industry’s smallest Ethernet controller. The integration of CP2200 with monolithic processor is able to realize Ethernet smart node applied to control and data acquisition of industrial field.
