How to understand ladder logic?

What is ladder logic programming?

  • Ladder logic programming is a coding language used to create circuit representations to help people build devices and to give instructions to controllers. While this can be used to build many different circuits, ladder logic programming primarily is used to make programmable logic controllers (PLCs).

What is a ladder logic program?

  • Ladder logic is widely used to program PLCs , where sequential control of a process or manufacturing operation is required. Ladder logic is useful for simple but critical control systems or for reworking old hardwired relay circuits.

What is a PLC ladder?

  • Ladder logic is a programming language used for PLC (Programmable Logic Controller) programming. It is a graphical PLC programming language which uses ladder diagrams to express logic operations with symbolic notation, much like the rails and rungs of a typical relay logic circuit.
