DeviceNet现场总线讲座第一讲现场总线发展概况与DeviceNet进入中国

现场总线是一个发展热点，但众多的现场总线往往使生产者和用户无所适从。是否已纳入ＩＥＣ标准、系统的开放性、技术能否得到有力的支持人格是否有竞争力等已成为人们选用何种总线的主要依据，ＤｅｖｉｃｅＮｅｔ已成为欧洲标准，即将成为ＩＥＣ标准。ＤｅｖｉｃｅＮｅｔ采用全球销售量最大的ＣＡＮ芯片，大规模的生产必将降低成本。ＯＤＶＡＣｈｉｎａ亦将提供优质的技术服务。

General Situation of Fieldbus and Introducing of DeviceNet into China

Fieldbus is the hotspot we are talking about and developing recently. But several kinds of the fieldbus often have baffled the device manufacturers and the users for fieldbus selection. Whether it is IEC standard, open, under available technical support and competitive or not is the major base on which to select the kinds of fieldbus. DeviceNet using CAN chip with the large scale over the world have been the European Standard and will be the IEC standard. The large scale manufacture consequentially result in the cost decreasing and ODVA China is avaiable to supply the high quality technical service as well.
