Thegeneral requ

    29、irements for the cabling and the physical layer are specified in EN 50325.EN 50325 is the international document for in-vehicle high-speed communication using the Controller Area Network(CAN) bus protocol. The scope of this document essentially is to specify the so-called data link layer and physica

    30、llayer of the communication link. The physical layer is subdivided into three sub layers. These are:a) Physical Signallingb) Physical Medium Attachmentc) Medium Dependent Interface4.2 Cabling4.2.1 General remarksIt is important to understand that electrical connections onto the bus have some impact

    31、upon the networkperformance, and that the practice is dependant upon the principles relevant to transmission lines rather thansimple electrical power circuits.4.2.2 Cable characteristicsThe main trunk circuit shall be at least a single twisted pair of nominal characteristic impedance of 120 at 1 MHz

    32、(tolerance 95 to 140 ). A shielded cable with overall braided shield is highly recommended especially forvehicles with electric drives, e.g. trams and trolley-buses. It is also recommended to provide an additional twistedpair in the cable to support ECUs with galvanic isolation. The cable shall not

    33、be connected in the form of a ring.4.2.3 Connections between devicesThe topology of the CAN-network is bus-shaped1), i.e. in contrast to a star-shaped or ring-shaped wiring thenetwork has two ends. At both ends, a nominal terminating impedance of 120 2)has to be connected betweenthe signals CAN_H an

    34、d CAN_L. Figure 1 shows a system with typical wiring.4.2.4 Galvanic isolationIt is recommended that isolation is applied if there are remarkable ground potential differences in different parts ofthe vehicle, or the bus length exceeds 200 m. A galvanic isolation is highly recommended practice for veh

    35、icles withelectric drives, e.g. trams and trolley-buses.However, it shall be ensured that all bus transceivers stay within their common mode voltage range at all times. It istherefore recommended to use only isolated ECUs (see Figure 2), or only non-isolated ones (see Figure 3)throughout the bus sys

    36、tem. If the bus system consists of both non-isolated, and isolated ECUs, their grounding hasto be designed carefully to prevent possible grounding problems. One approach to avoid ground loops is to supplypower to non-isolated ECUs via DC/DC converters.1) If repeaters are used, the network may appear

    37、 less bus-shaped. In this case the cable terminating and dead-end feederrequirements apply to each bus segment connected to the repeater.2) Depending on the bus configuration, deviations from 120 may be possible. It is, however, necessary to check theapplicability of other resistor values in each ca

    38、se. EN 50325-4 gives guidelines to this.NOTE The more nodes there are in the bus, the higher the termination resistor value should be.EN 13149-5:2004 (E)7It is also recommended that the power supply voltage for the isolated transceiver of the ECU is generated locallyinside the device by e.g. a DC/DC

    39、 converter. Some isolated devices need external supply voltage for theirtransceivers. To support both kinds of isolated ECUs now and in the future, it is recommended that the cable alsocontain both GND and CAN_V+.V+ and GND could be connected to the bus about in the middle of its length to minimise

    40、problems related to cableresistance especially if there are many ECUs supplied by V+, which introduces more current to these lines.Figure 1 Typical wiring of non-isolated devices using a shielded cable with one twisted pairFigure 2 Wiring example of isolated devices using a shielded cable with two t

    41、wisted pairsEN 13149-5:2004 (E)8The following rules should be followed when designing a CAN-network:a) The net shall be terminated at both ends with a resistor (between the signals CAN_L and CAN_H) as specifiedin EN 50325.NOTE See also guidelines in the CiA recommendation DR303-1 (see Bibliography).

    42、b) The shield CAN_SHLD should be connected only at one point to the earth potential (PE) unless other practicehas been found to be more appropriate.c) The overall allowed length of the trunk cable is dependent of the bit rate. See guidelines on recommendedoverall bus lengths in EN 50325-4.d) Dead-en

    43、d feeders shall be kept shorter than 0,30 m at 1 Mbit/s. At lower bit rates, EN 50325 allows longerdead-end feeders, but no exact rating is given. For lower than 1 Mbit/s bit rates, the rule of thumb for the dead-end feeder lengths given in the CiA recommendation DR303-1 (see Bibliography) can be us

    44、ed. However, incase of using dead-end feeder lengths obtained by DR303-1 formulas, the note given in EN 50325 aboutchecking the influence of cable resonator waves shall be followed.e) If unshielded cables are used, the allowable bit rate may be limited in order to meet the EMC requirements.Especiall

    45、y the length and the number of dead-end feeders (unterminated cables) should be kept to a minimum.This could be accomplished e.g. by using repeaters, see Annex B.f) A suitable cable type should be used. Always remember the voltage loss in the cable.Note: A guideline for selecting a cable is given in

    46、 the CiA recommendation DR303-1 (see Bibliography).g) Make sure not to wire CAN-lines directly next to disturbance sources. If this cannot be avoided, it isrecommended to use double-shielded cables.4.3 Devices and T-connectorsEach device (ECU) shall have a male bus cable connector. If the ECU suppor

    47、ts segment chaining of the cable, thesecond connector shall be the same connector type, but female. In the devices providing two bus cableconnections, and in the T-connectors, all the pins (including the free ones) shall be interconnected. The intention isthat there shall be no interruption on any b

    48、us cable wires to enable possible future specifications for the reservedpins. If the device contains both CAN_GND and GND pins, they shall be interconnected within the device.If the ECU is isolated, it is recommended that the power supply for the isolated transceiver be generated locallyinside the d

    49、evice by e.g. a DC/DC converter instead of utilising CAN_V+. It is recommended that CAN_V+ andGND be protected against reverse polarity.4.4 Connectors4.4.1 GeneralThe following connectors are preferred. When one of the following connectors is used in an application (both indevices and in T-connectors), the accompanying pin assignments shall be used.EN 13149-5:2004 (E)94.4.2 15-pin D-Sub type connectorFigure 3 15-pin D-Sub type connectorTable 1 Pin assignments for 15-pin D-Sub type connectorsP
