工业装置使用微机控制已日益普遍。大多数经济效益明显,数据准确,控制灵活,产量和质量均有较大幅度的提高。但在拥有若干个装置的一个工段或一个车间,只使用一台微机,往往感到不能满足要求,尤其当工业装置之间在生产工艺上彼此存在联系,需要互通信息时,更是如此。因此,在工段或车间设置分布式微/小计算机系统是较为合 The use of computer control of industrial installations has become increasingly common. Most of the obvious economic benefits, accurate data, flexible control, production and quality have more substantial increase. However, in a section or a workshop with several devices, the use of only one microcomputer often fails to meet the requirements, especially when the industrial devices have a connection to each other in the production process and need to communicate information. Therefore, in the workshop or workshop set up distributed micro / small computer system is more appropriate
