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 ...
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.
EtherNet/IP – IP stands for "Industrial Protocol". An implementation of CIP, originally created by Rockwell Automation; Ethernet Powerlink – an open protocol managed by the Ethernet POWERLINK Standardization Group (EPSG). FINS, Omron's protocol for communication over several networks, including Ethernet.
In some applications there is an advantage to being able to designate one station having a higher priority. Token Ring specifies an optional scheme of this sort, as does the CAN Bus, (widely used in automotive applications) – but Ethernet does not. In the Token Ring priority MAC, eight priority levels, 0–7, are used.
An address bus is a bus that is used to specify a physical address. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus). The width of the address bus determines the amount of memory a system can address.
PSTN network topology is the switching network topology of a telephone network connected to the public switched telephone network (PSTN).. In the United States and Canada, the Bell System network topology was the switching system hierarchy implemented and operated from c. 1930 to the 1980s for the purpose of integrating the diverse array of local telephone companies and telephone numbering ...
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.
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.
