A fieldbus control system is a form of decentralised control which links PLC's via a Controller Area Network (CAN) to control the manufacturing processes at the workshop-floor level. Such systems include Profibus, Netbus, LonWorks, Industrial Ethernet and many other. A programmable logic controller, PLC, or programmable controller is a small computer used for automation of real-world processes, such as control of machinery on factory assembly lines. ... Controller Area Network (CAN) is a multicast shared serial bus standard, originally developed in the 1980s by Robert Bosch GmbH, for connecting electronic control units (ECUs). ... LonWorks is a low bandwidth protocol created by Echelon Corporation for networking devices over media such as twisted pair, powerline and RF.

The exemplary fieldbus relay arrangements 560 are coupled to the fieldbus network via the spurs 550, which may provide power to the relay arrangements and communications with the other field devices attached to the fieldbus network.
This pressure sensing fieldbus device 780 may be used to monitor a pressure level 795, and may transmit a signal 760 to the fieldbus relay arrangement 700 when a particular predetermined alarm condition occurs.
This transducer block 830 may be used to convert the control signal into a form suitable for controlling the motor which is connected to relay outputs 850 of a relay module 840 of the fieldbus relay arrangement 800.
