大家好：问个问题行吗我按照NI的例子设定了modbus的slaver，同时安装了虚拟串口(左侧)，在开启后程序后，在虚拟串口的监控中没有发现VI并没有调用串口（COM8），但是我却能用调试软件正常调用对应的COM7串口，在正常使用时，我是把电脑和PLC相连，也发现是这样的情况，而且我的PLC的MODBUS主站调用其他MODBUS从站的数据一切正常。很显然就是labview程序这里没有调用COM8口，我一切都是按照NI的网站上来做的，地址在这里：http://digital.ni.com/public.nsf/allkb/9289275474D402678625795D0040CC02 ，只是把以太网改成了串口而已，难道还需要进行额外的配置吗，比如VISA？
