摘要
项目主要实现了在西门子PLC基础上利用中断程序功能和端口的自由口通讯方式,采集电阻率测试仪发出的微电压信号,并对该数据进行转换及处理.
This paper mainly studied on the collection of the micro voltage signal from the resistivity tester, and the data transformation and processing by using interrupt program function and port free port communication way based on Siemens PLC.
