Public transport - Road vehicle scheduling and control systems - Part 5: CANopen cabling specifications
This European Prestandard specifies the choice and the general application's rules of an onboard data transmission bus between the different equipment for service operations and monitoring of the fleet. This applies to equipment installed onboard buses, trolley buses and tramways only as part of a bus fleet operation. It excludes tramways when they are operated as part of a train, subway or metro operation. This equipment includes operation aid systems, automatic passenger information systems, fare collection systems, etc.
The equipment directly related to the safety-related functioning of the vehicle (propulsion management, brake systems, door opening systems, etc.) are excluded from the scope of the present standard and are dealt with in other standardisation bodies.
For the described application two bus systems are standardised. Part 1 to part 3 describe the WORLDFIP bus system and part 4 to part 6 describe the CANopen bus system. There is no ranking between the two bus systems.
This European Prestandard covers the link between equipment inside a single vehicle. Although it could be applied to multiple vehicles, this application is not explicitly covered by this standard.
Part 4 of this European Prestandard specifies the CANopen-based network. This specification describes the general architecture in terms of hierarchical layers according to the ISO reference model for Open Systems Interconnection (OSI) specified in ISO 7498.
Part 5 of this European Prestandard specifies in detail the connectors and the connector pin assignment and the cabling.
Part 6 of this European Prestandard specifies in detail the application profiles for the virtual devices in public transport.

Part 5: CANopen cabling specifications
This European Prestandard (ENV) was approved by CEN on 26 March 2002 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Introduction
This European Prestandard is part 5 of ENV 13149, which gives rules for on-board data transmission
systems.
This part 5 together with part 4 and part 6 describes a complete solution independent from part 1, part 2 and
part 3.

1 Scope
This European Prestandard specifies the choice and the general application's rules of an onboard data
transmission bus between the different equipment for service operations and monitoring of the fleet. This
applies to equipment installed onboard buses, trolley buses and tramways only as part of a bus fleet
operation. It excludes tramways when they are operated as part of a train, subway or metro operation. This
equipment includes operation aid systems, automatic passenger information systems, fare collection
systems, etc.
The equipment directly related to the safety-related functioning of the vehicle (propulsion management, brake
systems, door opening systems, etc.) are excluded from the scope of the present standard and are dealt with
in other standardisation bodies.
For the described application two bus systems are standardised. Part 1 to part 3 describe the WORLDFIP
bus system and part 4 to part 6 describe the CANopen bus system. There is no ranking between the two bus
systems.
This European Prestandard covers the link between equipment inside a single vehicle. Although it could be
applied to multiple vehicles, this application is not explicitly covered by this standard.
Part 4 of this European Prestandard specifies the CANopen-based network. This specification describes the
general architecture in terms of hierarchical layers according to the ISO reference model for Open Systems
Interconnection (OSI) specified in ISO 7498.
Part 5 of this European Prestandard specifies in detail the connectors and the connector pin assignment and
the cabling.
Part 6 of this European Prestandard specifies in detail the application profiles for the virtual devices in public
transport.

4 Requirements
All specific requirements for the applications, mentioned in the scope are described in the following chapters.
The general requirements for the cabling and the physical layer are specified in EN 50325-1.
EN 50325-1 is the international standard for in-vehicle high-speed communication using the Controller Area
Network (CAN) bus protocol. The scope of this standard essentially is to specify the so-called data link layer
and physical layer of the communication link. The physical layer is subdivided into three sublayers. These
are:
1 Physical Signalling
2 Physical Medium Attachment
3 Medium Dependent Interface
4.1 Cabling
4.1.1 General remarks
It is important to understand that electrical connections onto the bus have some impact upon the network
performance, and that the practice is dependant upon the principles relevant to transmission lines rather than
simple electrical power circuits.

especially for vehicles with electric drives, e.g. trams and trolley-buses. It is also recommended to provide an
additional twisted pair in the cable to support ECUs with galvanic isolation. The cable shall not be connected
in the form of a ring.

between the signals CAN_H and CAN_L. Figure 1 shows a system with typical wiring.
4.1.4 Galvanic isolation
It is recommended that isolation is applied if there are remarkable ground potential differences in different
parts of the vehicle, or the bus length exceeds 200 m. A galvanic isolation is highly recommended practice for
vehicles with electric drives, e.g. trams and trolley-buses.
However, it shall be ensured that all bus tranceivers stay within their common mode voltage range at all
times. It is therefore recommended to use only isolated ECUs (see Figure 1), or only non-isolated ones (see
Figure 2) throughout the bus system. If the bus system consists of both non-isolated, and isolated ECUs,
their grounding has to be designed carefully to prevent possible grounding problems. One approach to avoid
ground loops is to supply power to non-isolated ECUs via DC/DC converters.
It is also recommended that the power supply voltage for the isolated transceiver of the ECU is generated
locally inside the device by e.g. a DC/DC converter. Some isolated devices need external supply voltage for
their transceivers. To supp
