By means of combining the advantages of the pc104 bus embedded computer system and the profibus - dp fieldbus , manufacture a profibus - dp fieldbus communication main board based on pc104 bus embedded computer system . seeing from the combining , there has a very little information about it so far , so we must study in our selves . thit means we can do something in the field of industry watch 结合pc104总线嵌入式计算机系统和profibus现场总线的优点,研制一个基于pc104总线嵌入式计算机系统的profibus现场总线通信主卡。从pc104总线嵌入式计算机系统与profibus - dp现场总线技术结合来看,目前国内还不多见,可用的资料不多,基本要从头做起,在工业监控领域具有一定创新意义。
