ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhat is Configuration Management ?Definition according to IEEE Std-729-1983:“Configuration Management is the process of identifying anddefining the items in a system, controlling the change of theseitems throughout their lifecycle, recording and reporting the statusof items and change requests, and verifying the completeness andcorrectness of items”4


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhat is Configuration Management ?Definition according to EN50126-1999:“A discipline applying technical and administrative direction andsurveillance to identify and document the functional and physicalcharacteristics of a configuration item, control change to thosecharacteristics, record and report change processing andimplementation status and verify compliance with specifiedrequirements.”5


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhat is Configuration Management ?Or simpler:All measures to take care that a system that is made up ofdifferent parts continues to work properly over time, even if someof these parts change.6

ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhat is Configuration Management ?Or as an example:If you go on abusiness trip andtake your new mobilephone with you, butaccidentally togetherwith your old batterycharger, then yourConfigurationManagement hasfailed8


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhat is Configuration Management ?EN50126-1999:Life Cycle Phase 13 – Modification and retrofitThe objective of this phase shall be to control system modificationand retrofit tasks to maintain system RAMS requirements.… to establish, implement and regularly review a process tocontrol system modification and retrofit in the context of RAMS,including:- a RAMS impact analysis on the change- a procedure for verifying, validating and accepting the RAMSperformance of the system following modification and retrofitKey Output: A validated modified system.9

ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhat do we configure in ERTMS/ETCS?Examples:ERTMS/ETCS Standard• If the UNISIG SRS is updated to version 3.0.0, most otherdocuments have to be updated as well.ERTMS/ETCS Products• HW/SW components onboard a locomotive have to fittogetherERTMS/ETCS Applications• Assigning values to variables to identify balises, traincategories, track gauges etc. has to be coordinated.12


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhat do we configure in ERTMS/ETCS?Examples:Products versus Standard• If the SRS is updated to version 3.0.0, products will have tobe updated too to remain compliant.Projects versus Products• Projects have to use products only that fit together, soupdating a project to SRS 3.0.0 has to be done in parallelwith updating the products.Projects versus Standard• Engineering rules specified have to be followed in theengineering phase.13

ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhy Configuration Management ?The main reasons for running a Configuration Management inERTMS/ETCS areSafety and AvailabilitySafety can only be maintained if the configuration of a systems iskept consistent at all times.The availability of a system also depends largely on a propersystem configuration.15


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhy Configuration Management ?Safety Example:Extract from an FAA accident report:PROBABLE CAUSE: "(1) The captain and first officer's inadequatecockpit discipline, which resulted in the flight crew's attempt totakeoff without the wing flaps and slats properly configured; and(2) the failure of the takeoff configuration warning system to alertthe crew that the airplane was not properly configured for thetakeoff.16


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhy Configuration Management ?Availability Example:Recent press release:On 11. November 2004, more than 5500 EC-cashiers, bank tellermachines etc. have been out of service in Vienna due to a faultysoftware that had been installed the night before.17


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSWhy Configuration Management ?Safety and Availability Example:Rail (and road) traffic was interrupted for several hours becausethe vehicle configuration was incompatible with the infrastructure:18

ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSHow do we configure ERTMS/ETCS?Different measures have to be taken to ensure that a system isconfigured correctly at all times. These measures can be ofProcedural or Technical NatureSome of these measures have to be harmonized, others arespecific to individual countries, user, suppliers or projects.20


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSHow do we configure ERTMS/ETCS?Example of procedural measures:Handling of Variables in ERTMS/ETCSUIC and UNISIG have together specified a procedure to ensurethat values assigned to variables in the ERTMS/ETCS languageare correctly coordinated.One of these variables is the country code that serves a number ofpurposes, for example to ensure that the correct national shuntingspeed is supervised, or that a position report of a train is handledcorrectly.21


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSHow do we configure ERTMS/ETCS?Example of technical measures:System version managementA concept called “System Version” will be introduced in theERTMS/ETCS SRS 3.0.0.This forms the basis for future upgrades, as it ensures that an upanddownward compatibility between certain versions exists andthat an asynchronous upgrade of onboard and tracksideequipment is possible.22

ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSHow do we configure ERTMS/ETCS?Influence on the Trans European use of ERTMS/ETCS:• It will be possible to operate two subsequent major systemversions at any time• It will be possible to keep balises, loops and radio infillunits with even older system versions in useHowever• The introduction of new versions will require the eliminationof older versions, at least on interoperable parts of thenetwork, within certain time limits• The on-board equipment will have to be fitted to operateaccording to two system versions25


ALCATEL * ALSTOM * ANSALDO SIGNAL * BOMBARDIER * INVENSYS RAIL * SIEMENSHow do we configure ERTMS/ETCS?Example where a similar procedure is used:TCAS(Traffic Alert and Collision Avoidance System)• Most current version is 7.0• 7.0 is downward compatible to the previous version 6.04a• Version 7.0 is mandatory to operate in Europe, as it’sadvanced features are used in the crowded Europeanairspace• Version 6.04a can still be operated in North America forsome time, however planes operating worldwide had to beupgraded26
