Ladderdiagrammina

Ladderdiagrammina is a diagrammatic notation used for representing sequential logic and process control, blending elements of traditional ladder diagrams with a compact minimalist notation. It is designed to convey the flow of signals across a ladder-like structure while emphasizing clarity and modularity for education, documentation, and formal reasoning about control logic.

The notation keeps the familiar ladder diagram layout: two rails representing signal paths and a series of rungs that encode condition-action rules. In ladderdiagrammina, each rung is described with concise symbols or labels for inputs, conditions, and outputs, and wires indicate the direction of signal flow. The minimalist aspect, indicated by the name mina, aims to reduce visual clutter and highlight essential dependencies between conditions and results. The approach is used to model relatively simple control tasks and to support straightforward reasoning about safety properties and state transitions.

Applications and use cases include PLC programming, process control documentation, and introductory instruction in sequential logic. Advocates emphasize improved readability, modularity, and ease of verification compared with more verbose representations. Limitations include potential ambiguity for complex circuits or systems with many interdependent states, and the need for consistent conventions across tools and teams. An example rung might express a rule such as: if input X is true and Y is false, then set output Q. Ladderdiagrammina remains a niche notation but is discussed in scholarly and professional contexts as a pedagogical and documentation aid for ladder-based control logic.
