| | Ladder logic - Wikipedia, the free encyclopedia |
| | Ladder logic has "contacts" that "make" or "break" "circuits" to control "coils." Each coil or contact corresponds to the status of a single bit in the programmable controller's memory. | | | Ladder logic can be thought of as a rule-based language, rather than a procedural language. | | | Ladder logic or the Ladder programming language is a method of drawing electrical logic schematics. |

| | Section 2: Host Communication While a H-series programmable logic controller is running, a host computer may send commands in the form of ASCII strings to the controller to read or write to the inputs, outputs, relays, timers and counters. | | | The ladder logic program can use any of its outputs or relays as a flag to indicate to the host processor that a certain logic state has been reached and requires the host computer's attention. | | | While this may be a waste of the logic processing power of the CPU, it may be useful if the application needs the host computer to directly control all the inputs and the outputs. |

| | The Basics of Ladder Logic |
| | In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most implementations are done using a specialized microprocessor-based device called a programmable logic controller (PLC). | | | Ladder logic uses switch or relay contacts to implement Boolean expressions. | | | An XOR implementation for two inputs, which is actually [(A AND B') OR (A' AND B)] where the prime mark indicates a logical NOT or inversion, requires a type-A and a type-B contact for both inputs. |

| | What is a Programmable Logic Controller (PLC)? |
| | Programmable logic controllers were first created to serve the automobile industry, and the first programmable logic controller project was developed in 1968 for General Motors to replace hard-wired relay systems with an electronic controller. | | | A modern programmabl logic controller is usually programmed in any one of several languages, ranging from ladder logic to Basic or C. Typically, the program is written in a development environment on a personal computer (PC), and then is downloaded onto the programmable logic controller directly through a cable connection. | | | The programmable logic controller circuitry monitors the status of multiple sensor inputs, which control output actuators, which may be things like motor starters, solenoids, lights and displays, or valves. |
