In our VTScada tutorial, we used a digital I$/$O tag to indicate the status of the pump. Why did we use a digital rather than an analog I$/$O tag?

Question $6$ options:

Becuase the pump has a gauge that gives us a value between $0$ and $100.$

Because the pump has only two states, on or off.

Because the pump is controlled by a switch.

Because analog tags are only used for flow rate.
