The simplest PiPLC program — a button controls an LED.

I/O Assignment¶

Address	Description
`I:0/0`	Push button (input)
`O:0/0`	LED (output)

How It Works¶

When I:0/0 is TRUE (button pressed), the XIC contact passes power to the OTE coil, which energizes O:0/0 (LED turns on). When the button is released, the LED turns off.
