PLCs, or Programmable Logic Controllers, primarily use ladder logic programming due to its visual representation that resembles electrical relay logic diagrams. This format makes it particularly accessible for those in industrial settings who may be more familiar with traditional relay systems. Ladder logic consists of rungs that represent various logic operations, making it easy to understand and troubleshoot, even for those with limited programming experience.

The design of ladder logic allows for quick visualization of the control process and enables engineers and technicians to effectively implement and manage automation processes. It simplifies the process of creating control schemes and makes it easier to convey ideas among team members who understand the electrical concepts behind automation projects. Ladder logic is tailored specifically for industrial applications, which is why it remains the prevalent programming method used with PLCs, as opposed to other programming paradigms that might not align as closely with industrial control requirements.
