Digital inputs can vary continuously, while analog inputs are limited to two states.

Digital inputs require more power than analog inputs.

Analog inputs are always faster than digital inputs.

Digital inputs are discrete (0 or 1), while analog inputs are continuous values.

Rungs in ladder logic represent the physical layout of the ladder.

Rungs in ladder logic are used to indicate the power supply voltage.

Rungs in ladder logic serve as a visual guide for wiring connections.

Rungs in ladder logic signify individual control instructions or operations.
