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 .
The functional block diagram can picture: [1] functions of a system pictured by blocks; input and output elements of a block pictured with lines; the relationships between the functions, and; the functional sequences and paths for matter and or signals [2] The block diagram can use additional schematic symbols to show particular properties.
DeKalb–Peachtree Airport (IATA: PDK, ICAO: KPDK, FAA LID: PDK) is a county-owned, public-use airport in DeKalb County, Georgia, United States. [1] The airport is located in the city of Chamblee, just northeast of Atlanta. It operates 24 hours per day, although it is uncontrolled from 11:00 PM EST to 6:30 AM EST (Monday through Friday) or 7:00 ...
Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
In addition, when the scope of a diagram crosses the common LAN/MAN/WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes. For example, if a network appliance is intended to be connected through the Internet to many end-user mobile devices, only a single such device may be depicted ...
The component diagram extends the information given in a component notation element. One way of illustrating a component's provided and required interfaces is through a rectangular compartment attached to the component element. [3] Another accepted way of presenting the interfaces is the ball-and-socket graphic convention.
These tools have capabilities in common with drawing tools and network monitoring tools. They are more specialized than general drawing tools and provide network engineers and IT systems administrators a higher level of automation and the ability to develop more detailed network topologies and diagrams.
Function Block Diagram is one of five languages for logic or control configuration [2] supported by standard IEC 61131-3 for a control system such as a programmable logic controller (PLC) or a Distributed Control System (DCS). The other supported languages are ladder logic, sequential function chart, structured text, and instruction list.
