Question

我搜索并研究了我的问题，但这有点困难，因为我没有真正的错误（代码）来搜索。

我尝试在我的RPI和PLC之间进行通信，运行脚本后我得到（python Temp_buiten.py）响应如下，但脚本的输出是正确的，我将值作为Float输入PLC就像我想要的但是我得到的每个循环都在我的命令行中响应：

pi@raspberrypi:~/scripts $ python Temp_buiten.py
@▒
A▒
pi@raspberrypi:~/scripts $

我不是python程序员，所以我希望有人可以帮助我。我尝试运行的脚本：

Dave看起来你正在使用的S71200 python库每次调用时都会打印到控制台。第106行source to S71200.py 我一定忘了把它拿出来。 -SimplyAutomationized
