这是做的一个plc的上位软件，具体的功能是读取PLC温度模块的数值，还有一块数字千分表的数值，然后采集这些数据做一个实时的表格，这个表格横坐标是时间纵坐标是膨胀率。这个程序是给客户做的膨胀率测试仪的上位机程序，PLC还有一部分控制功能。-This is a PLC to do the PC software, the specific functions of numerical read PLC temperature module, there are numerical a digital dial gauge, and then collect these data make a real-time table, this table is time abscissa ordinate expansion rate. This program is the expansion program in PC ratio tester to customers do, PLC there is a part of control function.
