Profinet implements the interfacing to peripherals. [1] [2] It defines the communication with field connected peripheral devices.Its basis is a cascading real-time concept. Profinet defines the entire data exchange between controllers (called "IO-Controllers") and the devices (called "IO-Devices"), as well as parameter setting and diagnosi
Profibus electrical connector. Profibus (usually styled as PROFIBUS, as a portmanteau for Process Field Bus) is a standard for fieldbus communication in automation technology and was first promoted in 1989 by BMBF (German department of education and research) and then used by Siemens. [1]
Protocols for industrial Ethernet include EtherCAT, EtherNet/IP, PROFINET, POWERLINK, SERCOS III, CC-Link IE, and Modbus TCP. [1] [2] Many industrial Ethernet protocols use a modified media access control (MAC) layer to provide low latency and determinism. [1] Some microprocessors provide industrial Ethernet support.
A bus coupler is a device which is used to couple one bus to the other without any interruption in power supply and without creating hazardous arcs. A bus coupler is a breaker used to couple two busbars to perform maintenance on other circuit breakers associated with that busbar. It is achieved with the help of a circuit breaker and isolators.
Additionally more and more components are added to rail vehicles that need far more bandwidth than any field bus can provide (e.g. for video surveillance), so switched Ethernet IEEE 802.3 with 100 Mbit/s is being introduced into train sets (according to the EN 50155 profile). Still all the alternate vehicle buses are connected to the Wire Train ...
INTERBUS is a serial bus system which transmits data between control systems (e.g., PCs, PLCs, VMEbus computers, robot controllers etc.) and spatially distributed I/O modules that are connected to sensors and actuators (e.g., temperature sensors, position switches). The INTERBUS system was developed by Phoenix Contact and has been available ...
The BatiBUS defined in 1989 and used mainly in France, the Instabus extended to the European Installation Bus (EIB) and the European Home Systems Protocol (EHS) merged in 1999 to the Konnex) (KNX) standard EN 50090, (ISO/IEC 14543-3). In 2020 495 Member companies offer 8'000 products with KNX interfaces in 190 countries worldwide.
The hub-and-spoke tree topology of Ethernet makes it very easy to add and remove devices without upsetting the operating network. Because Foundation HSE is based on unmodified Ethernet, standard Ethernet tools can be used for installation qualification, testing, and troubleshooting. These tools speed up the resolution of communication problems.
