  2. Block diagram - Wikipedia

    en.wikipedia.org/wiki/Block_diagram

    A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams . Block diagrams are typically used for higher level ...

  3. Function block diagram - Wikipedia

    en.wikipedia.org/wiki/Function_block_diagram

    The function block diagram(FBD) is a graphical language for programmable logic controllerdesign,[1]that can describe the function between input variables and output variables. A function is described as a set of elementary blocks. Input and output variables are connected to blocks by connection lines. Inputs and outputs of the blocks are wired ...

  4. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    A simple flowchart representing a process for dealing with a non-functioning lamp. A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their ...

  5. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    Data-flow diagram. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system ). The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops.

  6. Block and tackle - Wikipedia

    en.wikipedia.org/wiki/Block_and_tackle

    A block and tackle [1] [2] or only tackle [3] is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads. The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load. The rope is threaded through the pulleys to provide mechanical ...

  7. Control theory - Wikipedia

    en.wikipedia.org/wiki/Control_theory

    Control theory is used in control system engineering to design automation that have revolutionized manufacturing, aircraft, communications and other industries, and created new fields such as robotics. Extensive use is usually made of a diagrammatic style known as the block diagram.

  8. State diagram - Wikipedia

    en.wikipedia.org/wiki/State_diagram

    A state diagram for a door that can only be opened and closed. A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states. Sometimes, this is indeed the case, while at other times this is a reasonable abstraction.

  9. Sequential function chart - Wikipedia

    en.wikipedia.org/wiki/Sequential_function_chart

    Sequential function chart ( SFC) is a visual programming language used for programmable logic controllers (PLCs). It is one of the five languages defined by IEC 61131-3 standard. The SFC standard is defined as Preparation of function charts for control systems, and was based on GRAFCET [ fr] (itself based on binary Petri nets [1] [2] ).
