大家好,
我们为实验新购入了一款C系列 安全模块NI9351
但是根据产品指南, 和里面的示例, 我还是不太理解这个模块的具体作用,或者它可以用于紧急停止装置吗?
请问大家了解这个模块吗?
它的具体作用是什么,又怎么操作呢?
感谢.

你好,感谢帮助, 请问这个紧急安全功能具体指哪些呢?是否可以监测电流,或者是否可以与温度感应器或其他功能装置相连呢?例如温度过高,便停止供电这一类?

您好,
这模块里有 safety logic solver。
您可以链接感应器(例如温度感应器)到这模块,然后设定些您想要的紧急安全功能(例如温度过高时要暂停运作之类)。
sensor -> logic solver -> final element
