NOT Gate

The NOT Gate is an automation building that inverts an input signal. When it receives a Red Signal, it outputs Green, and when it receives Green, it outputs Red. In practice, it is used anywhere a control circuit needs the opposite state from another automation signal, such as turning a device on when its controlling condition is false and off when that condition is true.

It behaves like a bitwise NOT on the Automation Ribbon. For example, if the input ribbon is 4-bit RRGR, the output becomes 4-bit GGRG. This makes the NOT Gate useful as a simple signal inverter in larger automation networks, especially when combined with sensors, timers, and smart power management.

Like other automation gates, the NOT Gate can be placed behind buildings and tiles, and it can share space with pipes or wires. This allows it to be tucked into compact layouts without needing open floor space, which is helpful when routing automation through crowded industrial rooms.

Its basic behavior is straightforward:

• Input Red → Output Green
• Input Green → Output Red

Because the gate simply flips the state it receives, it is often used to convert a “disable when active” setup into an “enable when inactive” setup, or vice versa. This is especially handy when a connected building or sensor produces the opposite logic from what the rest of the circuit expects.

In automated power setups, this can be used to control generators and other devices indirectly. For example, a Smart Battery can manage a Coal Generator by sending Green when the battery charge falls below the lower threshold and Red when it reaches the higher threshold; a NOT Gate can be inserted when a circuit needs the reversed behavior. More generally, the gate lets a design react to a signal by doing the opposite of the normal response, reducing the need to rebuild the whole control chain.

The NOT Gate’s function is especially simple compared with many other automation components, but that simplicity is exactly what makes it useful. Whenever a logic line needs inversion, it provides a direct and reliable way to do so without changing the upstream source or rewriting the broader system.
