摘要
叙述了日本与欧美厂商的PLC性价比,由系统配置剖析它们在数字开关量和模拟量各自的优异,可根据具体要求,合理选配以求得到最佳性价比。同时,介绍目前世界上PLC的发展趋势。
In this paper,the ratio of the performance and price for PLC between Japan and Europe & American are described.The advantage and defect of on the digital switching amount and analogue is dissected bytheir sysematic configuration.According to concrete requirement,PLC can be reasonably selected to obtainoptimum ratio of the perfrmance and price.At present,the development of PLC in the world are introducedat the same thime.
