When choosing the economy,it is necessary to meet the requirements of control scalability,controllability,input-output ratio,etc.,combined with the reference conditions,and finally adopt the more economical PLC.The number of I/O points has a lot of influence on the price.Each I/O unit needs to increase some investment.When the number of interfaces is established to a fixed number,the matching memory size,rack,motherboard,etc.will continue to increase.Therefore,the increase in the number of points has an impact on factors such as processor selection,memory size,and control function requirements.It should be considered comprehensively when estimating and selecting,so that all control systems can get the best performance-price ratio.
选择经济性时,要用满足控制的可扩展性、可控制性、投入产出比等要求,结合参考条件,最后采用经济较突出的PLC。I/O点数对价格有很多影响,每建立一块I/O单元就需提高一些投资,当接口量建立到固定的数量后,匹配的存储器大小、机架、母板等也要持续变多,所以点数的升高对处理器选择、存储器大小、控制功能要求等因素都有影响。在估算和选择时应全面考虑,使全部控制系统得到最优的性能价格比。
