You can use your computer browser to tell it what to do, or you can use a simple visual interface on your iPad/smartphone when you are in the family. How to control it? Hauntbox supports up to 6 inputs and 6 outputs. First, go to the settings page and set your input and o

I have mentioned some texts about the SCL Of The SIEMENS Automatic Control System some time ago. I suggest you briefly introduce the automatic control system here. Here I will give a brief introduction, in fact, we often see automated control in our daily lives. Systems, such as our crane-type elevator and crawler elevator, are applications of automated control systems. Let's make a simple analysis of this
