in Chapter 4 ‘Characteristics of the rolling stock subsystem’, clause 4.2.8.2.8 ‘On-board energy measurement system’ is replaced by the following clause: ‘4.2.8.2.8 On-board energy measurement system 4.2.8.2.8.1 General (1) The on-board energy measurement system (EMS) is the system for measurement of all active and reactive electric energy taken from or returned (during regenerative braking) to the overhead contact line (OCL) by the electric unit. (2) The EMS shall include at least the following functions: Energy measurement function (EMF) as set out in clause 4.2.8.2.8.2, data handling system (DHS) as set out in clause 4.2.8.2.8.3. (3) A suitable communication system will send the compiled energy billing data sets (CEBD) to an on-ground data collecting system (DCS). The interface protocols and transferred data format between EMS and DCS shall fulfil the requirements set out in point 4.2.8.2.8.4. (4) This system is suitable for billing purposes; the data sets defined in point 4.2.8.2.8.3(4) provided by this system shall be accepted for billing in all Member States. (5) The EMS rated current and voltage shall be matched to the electric unit rated current and voltage; it shall continue to function correctly when changing between several traction energy supply systems. (6) Data stored in the EMS shall be protected against loss of the power supply and the EMS shall be protected from non-authorised access. (7) An on-board location function providing location data originated from an external source to the DHS shall be provided in networks where such function is necessary for billing purposes only. In any case, the EMS system shall be able to accommodate a compatible location function. If the location function is provided, it shall fulfil the requirements set out in specification referenced in Appendix J-1, index 116. (8) The fitment of an EMS, its on-board location function, the description of on-board to ground communication and the metrological control including the accuracy class of the EMF shall be recorded in the technical documentation described in clause 4.2.12.2 of this TSI. (9) The maintenance documentation described in clause 4.2.12.3 of this TSI shall include any periodic verification procedure to ensure the required accuracy level of the EMS during its lifetime. 4.2.8.2.8.2 Energy measurement function (EMF) (1) The EMF shall ensure the measurement of the voltage and current, calculation of the energy and production of energy data. (2) The energy data produced by EMF shall have a time reference period of 5 minutes defined by the Universal Time Coordinated (UTC) clock time at the end of each time reference period; originating from the time stamp 00:00:00. It is permitted to use a shorter measuring period if the data can be aggregated on-board into 5 minutes time reference period. (3) The accuracy of EMF for active energy measurement shall comply with clauses 4.2.3.1 to 4.2.3.4 of the specification referenced in Appendix J-1, index 117. (4) Each device containing one or more functions of EMF shall indicate: metrological control, and its accuracy class, according to the class designations specified in the specification referenced in clauses 4.3.3.4, 4.3.4.3 and 4.4.4.2 of the specification referenced in Appendix J-1, index 117. (5) The conformity assessment of the accuracy is set out in clause 6.2.3.19a. 4.2.8.2.8.3 Data handling system (DHS) (1) The DHS shall ensure the production of compiled energy billing data sets for energy billing purposes, by merging data from the EMF with time data and, when required, geographical position, and storing it ready to be sent to an on-ground data collecting system (DCS) by a communication system. (2) The DHS shall compile the data without corrupting them and shall incorporate data storage with a memory capacity sufficient to store the compiled data of at least 60 days continuous operation. The time reference used shall be the same as in the EMF. (3) The DHS shall have a capability to be interrogated locally on-board for audit and data recovery purposes. (4) The DHS shall produce compiled energy billing data sets, (CEBD), by merging the following data for each time reference period: — unique EMS consumption point identification (CPID) as defined in the specification referenced in Appendix J-1, index 118, — end time of each period, defined as year, month, day, hour, minute and second, — location data at the end of each period, — consumed/regenerated active and reactive (if appropriate) energy in each period, in units of watt-hour (active energy) and var-hour (reactive energy) or their decimal-multiples. (5) The conformity assessment of compilation and handling of data produced by DHS is set out in clause 6.2.3.19a. 4.2.8.2.8.4 Interface protocols and transferred data format between EMS and DCS The data exchange between EMS and DCS shall fulfil the following requirements: — The application services (service layer) of the EMS shall comply with clause 4.3.3.1 of the specification referenced in Appendix J-1, index 119. — User access rights for these application services shall comply with clause 4.3.3.3 of the specification referenced in Appendix J-1, index 119. — The structure (data layer) for these application services shall comply with the XML schema as defined in clause 4.3.4 of the specification referenced in Appendix J-1, index 119. — The message mechanism (message layer) for supporting these application services shall comply with the methods and the XML schema in clause 4.3.5 of the specification referenced in Appendix J-1, index 119. — The application protocols for supporting the message mechanism shall comply with clause 4.3.6 of the specification referenced in Appendix J-1, index 119. — The EMS shall use at least one of the communication architectures in clause 4.3.7 of the specification referenced in Appendix J-1, index 119.’;
