In a bus network, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority. [3] A bus network forms a single network segment and collision domain. In order for nodes to share the bus, they use a medium access control technology such as carrier-sense multiple access (CSMA) or a bus ...
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...
Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1] [2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.
The Open Systems Interconnection (OSI) model is a reference model from the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection."
Token Bus was standardized by IEEE standard 802.4. It was mainly used for industrial applications. Token Bus was used by General Motors for their Manufacturing Automation Protocol (MAP) standardization effort. [4] This differs from Token Ring networks in that the endpoints of the bus do not meet to form a physical ring.
KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking: [4] Sensors (e.g. push buttons, thermostats, anemometers, movement) gather information and send it on the bus as a data telegram;
Bus contention is an undesirable state in computer design where more than one device on a bus attempts to place values on it at the same time.. Bus contention is the kind of telecommunication contention that occurs when all communicating devices communicate directly with each other through a single shared channel, and contrasted with "network contention" that occurs when communicating devices ...
Modbus or MODBUS is a client/server data communications protocol in the application layer. [1] It was originally designed for use with programmable logic controllers (PLCs), [2] but has become a de facto standard communication protocol for communication between industrial electronic devices in a wide range of buses and networks.
