Ladder diagrams were once the only way to record programmable controller programs, but today, other forms are standardized in IEC 61131-3. For example, instead of the graphical ladder logic form, there is a language called Structured text , which is similar to C, within the IEC 61131-3 standard.

It was first published in December 1993 [1] by the IEC; the current (third) edition was published in February 2013. [2] Part 3 of IEC 61131 deals with basic software architecture and programming languages of the control program within PLC. It defines three graphical and two textual programming language standards: Ladder diagram (LD), graphical
Ladder diagram may refer to: Message sequence chart, in Unified Modeling Language (UML) Ladder logic, a method of drawing electrical logic schematics. A ladder diagram represents a program in ladder logic. A method of juggling notation; One type of Feynman diagram
Diagrams for the cascade pattern, siteswap: 3 Shannon's theorem for the cascade pattern. Juggling notation is the written depiction of concepts and practices in juggling. [1] [2] Toss juggling patterns have a reputation for being "easier done than said" – while it might be easy to learn a given maneuver and demonstrate it for others, it is often much harder to communicate the idea accurately ...

Example Ladder Logic Diagram The schematic diagrams for relay logic circuits are often called line diagrams, because the inputs and outputs are essentially drawn in a series of lines. A relay logic circuit is an electrical network consisting of lines, or rungs, in which each line or rung must have continuity to enable the output device.
A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), [3] or after many moves with as few as three pieces in an endgame position.
