工业领域的设备集成化、数字化、网络化、智能化已是必然趋势,“信息孤岛”早已不能适应当今的信息化,急需将现场设备的控制与数据采集网络化,那么具有通信作用的智能节点是使设备网络化的关键。CP2200 是工业领域最小的以太网控制器,它再与单片机相结合,便可实现以太网智能节点,来完成工业领域中现场数据采集与控制的任务。关键词:智能节点;以太网;CP2200;TCP/IP 协议Abstract:It is necessary trend that facility is integrated, digitized, networked and smarted inindustrial 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.Keywords:Smart Node; Ethernet; CP2200; TCP/IP Protocol
