目前,加工工业可望用 PC 构成一个功能虽有限但灵活多变的微机。实际上,各种小巧耐用的 PC 用场很多——尤其在顺控和开关量控制中更为合适。随着分散型控制的日益普及,把 PC 作为实用和投资效益高的就地或专用控制器来推广使用,肯定是预料之中的事。PC 的选用PC 的选用尚存在一些问题。各种 PC 的性能和结构不尽相同,部件和术语也不统 At present, the processing industry is expected to form a PC with a limited but flexible microcomputer. In fact, a variety of small and durable PC with many uses - especially in the sequence control and switching control more appropriate. With the increasing popularity of decentralized control, it is certainly expected that the PC will be promoted as a practical and cost-effective on-site or dedicated controller. PC use PC selection there are still some problems. The performance and structure of various PC are not the same, parts and terms are not unified
