Interbus
Encyclopedia
INTERBUS is a serial bus
system which transmits data between control system
s (e.g., PC
s, PLC
s, VMEbus
computers, robot
controllers etc.) and spatially distributed I/O modules that are connected to sensor
s and actuator
s (e.g., temperature sensors, position switches).
The INTERBUS system was developed by Phoenix Contact
and has been available since 1987. It is one of the leading Fieldbus
systems in the automation industry and is fully standardized according to European Standard EN 50254 and IEC 61158.
At the moment, more than 600 manufacturers are involved in the implementation of INTERBUS technology in control systems and field devices.
Serial communication
In telecommunication and computer science, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels...
system which transmits data between control system
Control system
A control system is a device, or set of devices to manage, command, direct or regulate the behavior of other devices or system.There are two common classes of control systems, with many variations and combinations: logic or sequential controls, and feedback or linear controls...

Programmable logic controller
A programmable logic controller or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines...

VMEbus
VMEbus is a computer bus standard, originally developed for the Motorola 68000 line of CPUs, but later widely used for many applications and standardized by the IEC as ANSI/IEEE 1014-1987. It is physically based on Eurocard sizes, mechanicals and connectors , but uses its own signalling system,...

Sensor
A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated...
s and actuator
Actuator
An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, usually in the form of an electric current, hydraulic fluid pressure or pneumatic pressure, and converts that energy into some kind of motion. An actuator is the mechanism by which...
