为什么我的WSN串口节点不能返回端口错误?



主要软件:
主要软件版本: N/A
主要软件修正版本: N/A
次要软件: Driver Software>>NI-WSN
硬件: Wireless Sensor Network>>WSN Nodes

问题: 当使用串口节点WSN-3230或者WSN-3231的时候,我怀疑产生了一些错误,但是并没有返回任何的错误,这是为什么?

解答: 端口错误诸如奇偶校验不匹配或者是帧错误,是不会被返回的,除非数据被端口成功地读取。使用WSN串口节点的时候,只有成功读取了串口数据才会返回错误。如果你想要返回错误,但并不读取数据,你可以使用Serial Port Bytes at Port.vi来实现。
