30、ase protocol to providesolutions to users in industrial environments who have a need for simple communications and diagnostics.The application layer of each network has been created to meet specific performance and marketrequirements.The objective of the interface user is a gain in productivity that
31、 may be realised through reduced wiring,reduced start up time, improved quality of output and reduced down time. The interfaces described providelow-cost connectivity between low-voltage switchgear, controlgear, control circuit devices, switching elementsand controlling devices (e.g. programmable co
32、ntrollers, personal computers, etc.) and eliminate expensivehardwiring. The direct connectivity provides improved communication between devices as well as importantdevice-level diagnostics not easily accessible or available through hardwired I/O interfaces.The interfaces described are based on a bro
33、adcast-oriented communications protocol - Controller AreaNetwork (CAN). The CAN protocol was originally developed by Robert Bosch GmbH for the Europeanautomotive market for replacing expensive, wire harnesses with low cost network cable on vehicles. As aresult, the CAN protocol has fast response and
34、 high reliability and the protocol has been standardised as ISO11898. Chips are available in a variety of packages with temperature and noise immunity ratings well suitedto the industrial automation market. Demand for CAN is the key driver in the low price with highperformance characteristic of CAN
35、chips.As a result of the common use of CAN, the interfaces described provide a common set of capabilities that areideally targeted to applications which include simple devices, limited distance and limited amount of data pertransmission.1 ScopeThis European Standard applies to controller-device inte
36、rfaces that provide defined interfaces betweenlow-voltage switchgear, control gear, control circuit devices, switching elements and controlling devices (e.g.programmable controllers, personal computers, etc.). It may also be applied for the interfacing of otherdevices and elements to a controller-de
37、vice interface.This standard specifies requirements for controllers and devices utilising these interfaces, including not onlythe communication protocol specification, but also associated relevant electrical and mechanicalcharacteristics. It also specifies the electrical and EMC tests required to ve
38、rify the performance of eachcontroller-device interface when connected to the appropriate controllers and devices.This part 1 establishes a consistent terminology and format for the subsequent interfaces. It also harmonisesrequirements of a general nature in order to reduce the need for testing to d
39、ifferent standards, increaseunderstanding and facilitate comparisons of controller-device interface standards. Those requirements of thevarious controller-device interface standards which can be considered as general have therefore beengathered in this part 1.In addition to meeting the specific requ
40、irements stated in this part 1, the controller-device interfaces includedin this standard are documented in the English language in accordance with the requirements specified in this part 1, are already in use in commercial products and running in industrial plants, are available in quantity and at
41、low price, are available from several sources and commercialised openly, to satisfy the tests specified, amongst others, in EN 61000-4-2, EN 61000-4-3, EN 61000-4-4,EN 61000-4-5, and EN 61000-4-6 against the test levels specified in EN 50082-2, have appropriate mechanisms for transmission error dete
42、ction, are open, widely accepted, well documented, stable and support inter-operability,EN 50325-1:20026 are complete and describe the necessary interfaces in sufficient detail to enable error-freeimplementation, are free of any restriction related to testing the implementation.For each controller-d
43、evice interface only two documents are necessary to determine all requirements andtests: the general requirements of this standard, referred to as “part 1“ in the relevant parts covering thevarious types of controller-device interfaces; the relevant controller-device interface standard hereinafter r
44、eferred to as the “relevant controller-deviceinterface standard“ or “controller-device interface standard“.The solutions described in this standard have been used for many years by industry to solve applicationrequirements involving low-voltage switchgear and controlgear. They are characterised by:
45、their ability to power connected devices directly from the network; their ability to operate in harsh environments typified by those encountered at the machine level bycontrols in industrial applications; usage of the sophisticated medium access rules of CAN which allows both organisation of traffic
46、 basedon user-assigned priorities and efficient resolution of occasional access conflict; a wide range of exchange services allowing precise tailoring of data exchange to the actual applicationneeds as well as simultaneous distribution of data to a selected set of connected devices; their capability
47、 to simultaneously support data acquisition, diagnostics, messaging andprogramming/configuration as required, amongst others, for systems interfacing controllers tolow-voltage switchgear and controlgear in industrial applications.NOTE The controller-device interface standards currently part of this
