# Configuring Digital Inputs
To make a Local I/O Channel operate as a digital input, first click the channel in the sidebar to go to the channel settings view:
Then click **Digital Input** in the view that appears:
Finally, click **Save**:
Digital inputs may have a **Polarity** of **Normal** or **Reversed**. In **Normal** polarity, if the **Raw Input** value is 0, the **System Value** will also be 0 (this value is written to the configured tag, which is **channel1** in this case):
In **Reversed** polarity, if the **Raw Input** value is 0, the **System Value** will be 1, and vice versa:
