"Add to cart" button Ladder logic is an integrated programming language for use in programmable logic controllers (PLCs). It was originally based on the ladder diagram, hence its name, which is still widely used today in industry because of its intuitive representation of the control flow relationship between operations and steps. Its use is not limited to programmable logic controllers, but is also used in computer systems hardwired to the hardware. Ladder logic is a programming language that can be used with PLCs to control machinery or processes. It uses the metaphor of a ladder with two sides, normally one side for inputs and outputs and one side for processing operations. The processing operations include "gates" which are linked by rungs or "rungs" (representing specific places in the program). Ladder logic was originally designed to mimic relay logic. Its main advantage is that it can directly interface with existing electromechanical control equipment already installed in many facilities; therefore, it has become the most common programming language found in PLCs. Ladder logic is primarily used to program PLCs; however, it may be used for other applications including sequencing, text processing and control panel programming. In ladder logic operations are connected by rungs to form a ladder diagram that, similar to a flowchart, illustrates the best order of execution of operations for achieving a programmed result. In PLCs, each rung is associated with a unique input or output instruction. One rung's output(s) become the input(s) to another rung's input(s); conversely, one rung's inputs become the output(s) of another rung. Thus, the instruction sets for various levels of rungs are independent. Each rung will have default or initial conditions that are defined when the rung is installed in the PLC. For example, consider a simple program to "turn on" a relay by sending it an output instruction to turn on a light. The program would be written as follows: The command ""G1 ON"" will cause the relay to turn on its contacts high while activating any other outputs that may exist in the PLC's hardware. This represents the following ladder diagram: Note that any input instructions at rung level 1 will be ignored until instructions at rung level 2 are given an input, and so forth. The third rung's input is both an input and an output, which is the case for all rungs that directly use inputs or outputs. Also, since any time an output turns on it becomes the input to the next rung, output 1 will also be sent to be used as an input 2 after output 2 has been used as an input 1. This causes the PLCs hardware to activate all outputs whenever one is activated. Below can be seen a ladder logic program example which illustrates how to turn on power supply B when power supply A turns on. cfa1e77820
