摘要
目前市场上的总线协议标准种类繁多,其中IEC标准委员会主流的就有8种总线协议,新的协议也层出不穷,这里有工业领域特殊工艺流程应用的需要也有各个参与制定协议厂商自身经济利益的排他性考虑,总之现场总线协议标准目前还看不到统一的希望。面对目前多总线协议共存的情况,而每种总线不可能使用用于所有工业领域的现实。同样在同一系统中也可能存在多总线协议应用的问题。及用户会面临使其在同一系统中总线协议转换的问题。
various types of bus protocol standard on the market at present, the mainstream of IEC standards committee has eight kinds of bus protocol, the New Deal also emerge in endlessly, here are the needs of the industrial applications of special process also have the manufacturer＇s own economic interests in the development agreement exclusive consideration, anyhow there has no unified fieldbus protocol standard ofhopeo In the face of the multibus protocol coexistence, and each bus can＇t be used for all in the field of industrial reality.Also there are likely to be more in the same system bus protocol application problems.And the user will be facing in the same bus protocol conversion problem in the system.
