COMAP Components System

COMAP consists of the basic module COMAP Professional and several optional modules. All of these modules can be freely combined with the basic module. In consequence of the individual combination of modules, COMAP can be tailored to the needs of your company.


The basic VPI version of COMAP cannot be combined with other modules.

Basic module COMAP professional

The basic module provides all the functionality to manage your assets and to make their technical parameterization:

The products, for example freight waggons, locomotives and wheelsets, are created and administrated in the Product Management. For each product a range of key data can be managed. In addition, measures taken or planned can be seen, as well as the assignment to the orders.

A product which has been created can be configured according to the definitions in the Structure Administration. This means, for example, that the structure of a gas tank waggon can be created according to VPI 08. The process can be done manually or take place at the click of a button based on structure and series templates Workshops have the possibility to configure a waggon structure for reception (waggon arrival) and a structure for dispatch (waggon departure). The product structure of the rolling stock at receipt and dispatch can be documented for each action taken. This permits the user to document modification measures in workshops and enables hire companies to identify changes during leasing period.

Sub-products can be installed or removed from a product structure. For instance, a wheelset can be installed to a waggon and all of the wheelsets data, including the attached photographs and documents, can be taken over into the waggon. In principle, this function allows the installation and removal of all waggon components.

Electronic work papers allow recording the individual data, which is acquired per product, and reporting back work executed and used material. According to the work profile, the user will see exactly the fields he needs in his area of work. Besides, he can see at a glance which compulsory data he has to enter. This information is based on the order and maintenance plan. In addition to recording new values, unchanged values can be validated.

Technical data can be recorded online and offline. Offline means that the computer or the mobile device which is used for data recording does not have to be connected to the server. Therefore, waggon data can also be recorded when there is no WIFI or UMTS/LTE connection. The synchronization takes place as soon as the device has reconnected.

In addition to the technical data, work executed and material used attachments, for example photographs, documents and protocols can be assigned to a product. The assignment takes place through the technical structure. For instance, a photograph can be assigned to the bearing on the inner A side of the third wheelset of the waggon.



Measures can be created and managed in COMAP. A measure specifies which actions have to be taken in a workshop and which technical data has to be documented. A measure can include scheduled maintenance plans as well as repair actions. It is possible to bundle single work steps, which for example derive from a project, with other measures. If multiple measures exist for one product, they can be merged together. This allows the user to commission and execute repair works and scheduled maintenance plans in one step.

Maintenance plans and work steps published by VPI can be used in the COMAP Base Module. Individual maintenance plans or work steps can be created and used in the Measure Management with the additional components “Work Step Catalogue” and “Project Management”.

Commissions and production orders can be created and administrated based on created measures in the component Order Management.

Commissions enable the ECM/keeper to generate detailed maintenance or repair orders which can be printed to PDF or sent digitally via VPI 08 to a workshop. A digital transmission requires using web services.

Workshops can create production orders and use work papers in COMAP to provide the production orders digitally. If production orders are provided and work is reported back digitally, the software validates the technical documentation regarding completeness according to the production order.

COMAP permits the ZIP-based data transfer according to VPI 08. This means that waggon and wheelset data can be received from and sent to any IT system which conforms to VPI 08. Events, attachments and planned/executed work steps as well as errors and defects can be transferred alongside the technical data. COMAP ensures that the generated ZIP files conform to the current VPI 08 scheme.

Through separate settings the export data can be filtered for each customer. This allows a contractually agreed amount of data to be set which has to be delivered to a specific customer.

The data history allows reviewing all data recorded for a product in a time history. Additionally, the software includes basic features of a document management system (DMS) and can access all historic attachments. This functionality covers major requirements of an ECM to hold available all technical data of its rolling stock including wheelsets. Furthermore, maintenance workshops can access the prior workshop cycles of a waggon or wheelset.

By setting up work profiles in COMAP one can determine which user can view and edit what type of product data. Additionally, it can be determined which user can report back what kind of work. An employee in wheelset processing will automatically only see the wheelset data and work steps according to his work station using his electronic work papers. This provides a high degree of transparency and data security.

The software takes the product configuration into account and ensures that only applicable data and work can be edited and reported back.

Work profiles can be created and administrated. This way, all input masks can be adjusted to the company’s own processes and users can be guided in their work. Additionally, an option in the work profile configuration can be set which allows filtering the input masks shown by client and/or order. This ensures that only relevant data will be recorded.

The Structure Administration is the basis for COMAP and allows the data modelling of products and components.

Product structures:
Product structures define all technical structures which form the basis for products (vehicles, wheelsets, etc.). Product structures determine composition and properties of products. Any kind of product structures can be created and administrated. Thus, COMAP is able to completely model locomotives, commuter trains or infrastructures.

Product Types:
Product types can be defined based on product structures. A product type, for example, is a waggon or wheelset. These two product types are preconfigured in COMAP for VPI users. Moreover it is possible to add other product types such as distributors, for instance. Products have the characteristic that they can be installed or removed in/from products and that they have their proper history.

List Administration:
The list administration allows defining selection lists for data fields of product structures. These lists specify a set of entries which the user can pick from in data recording for the data fields that they are connected with.

Series allow the user to create templates from which waggons or wheelsets are generated in the product administration. This way it is possible to define templates for waggons or trains with specific characteristics, such that a template could completely preconfigure a tank waggon with four wheelsets. In addition to the product structure, operating and maintenance limits can be defined.

Part catalogue:
Part catalogues can be defined for each component in the product structure. It is possible to create, for example, a catalogue for brakes. In data recording these catalogues can be accessed. Selecting a part from a part catalogue executing a measure will automatically set the defined values of the selected part. Parts from the catalogue can be used in series and work steps as well.

If COMAP is used to comply with VPI 08, the software will be preconfigured with the complete structure administration by Sternico. In combination with the Sternico Software Assurance the software and the configuration for VPI 08 will always be updated. The VPI configuration can be extended to fit the customer’s needs if necessary.

According to EWT (European Wheelset Traceability) an ECM has to provide for the traceability of wheelsets. The software guarantees a gapless traceability of all wheelsets as well as of all other components. The history of install/removal procedures that can be accessed is bidirectional. For example, a wheelset shows the waggons it was installed in and a waggon shows all wheel sets that were installed in it. The components which are to be traced can be defined freely by the user. This allows the user to trace bogies and distributers as well.

Views are tabular lists of products, measures and errors/defects which can be administrated in COMAP. For every product type a standard view exists which lists all products of the corresponding type. If wheelsets are managed in COMAP, the standard view lists all existing wheelsets. Aside from only listing products, a view has search and filter fields. This way, a wheelset with a specific wheelset number can be searched or a list can be requested which includes only wheelsets that are currently installed in a waggon.

The software uses standard views and allows the user to create further individual views and to use them for analyses. It is possible to define company-wide views which are available to all users or to set up individual views for single users. Within the definition of a view the user can access the complete technical data, master data as well as orders in any combination.

The following parameters can be accessed for each view:

  • Permanent filters which limit the listed products, measures and errors/defects
  • Search fields which are offered to the user using the vie
  • Information (columns) of the tabular list

For example, a view could be configured that lists all waggons which should be finished within the next five days. Or a view could be defined to search wheelsets of a certain type and customer. The list of wheelsets found could then show columns for the wheelset number, wheelset type, customer and the storage location.

COMAP includes master data for products such as the product status or a leaser. If additional master data is needed, those data fields can be defined. The user can create new data fields, for example, based on dates or selection lists as well as system tables like user accounts or departments and suppliers.

It is possible to define in which product types these fields can be accessed and which departments have the rights to read or write these fields.

The following example explains the functionality: The field „Priority“ is created based on a selection list for the product type „Waggon“.

The selection list has the entries „high“, „medium“ and „low“. Then the field will be assigned to the department „Production planning“ with rights to read and write the field while the department „Production“ only gets rights to read. Now the department „Production planning“ can access the field for every waggon to set a priority but the department „Production“ can only read the priority.

The Master Data Management the possibility to adapt COMAP to proper needs. Therefore, all data needed that is not part of the technical data can also be saved and documented. All those fields can be accessed in views as well.

Technical data which has been recorded can be signed by entering a PIN. Two different goals can be achieved by this. On the one hand data is protected from modifications. On the other hand signing data can be used to affirm the correctness of the data entered. This way, the data recording can be separated into two process steps. In the first step the worker records data and in a second step the data gets validated by QA and signed. Especially for safety relevant parts like brakes this verification is to aim for.

In general, COMAP can be used by all appliances that run a Microsoft Windows desktop operating system. Therefore, mobile use of laptops or tablet computers is possible. In order to enhance the usability of mobile devices the Mobile Package includes a special touch user interface has been developed for finger-tip operation. It is possible to switch between the standard and the touch user interface for each device as needed.

Additionally, the Mobile Package includes a special software for PDA devices running Windows Mobile. This way data can be recorded with handy devices suited for rugged environments. Furthermore, there is a function available to position products by scanning barcodes. This allows fork lift drivers, for example, to scan the barcode of a wheelset and a storage location and hereby place the wheelset into stock (prerequisite is the component „Positioning“).


The individual components expand the basic module and can be combined. Decide for yourself which functions you need.

This component allows setting up complex maintenance plans with a simple to use graphical editor. The plans may contain cyclic elements as well as coupled elements and are fully versioned including an approval process to comply with ECM requirements. The software automatically creates future measures based on the maintenance plans.

Plan maintenance stays based on time and operational parameters, such as mileage or motor hours. In case of planning based on operational parameters, COMAP forecasts the date of the next limit. To make use of operational parameters the component Operating data management must be licensed.
COMAP automatically assigns maintenance plans to assets using conditions. E.g. COMAP could assign maintenance plans based on the asset series, plan A is assigned to series 4711 and plan B is assigned to series 0815. Another way to set up a condition is the use of lessors. This way it is possible to assign a different maintenance plan to an asset if the lessor transports special products, for instance in case of tank wagons which thus need a special treatment of gaskets.

It is also possible to set up component-based maintenance plans. Thus, for instance, it is possible to use time-based intervals for tank inspections and mileage-based parameters for wheelsets. According to the maintenance plans, COMAP plans and creates all measures including the correct maintenance levels automatically.
Control contractual lead-times and budgets combined with maintenance companies and maintenance levels and work to execute. Find overlong lead-times and interference factors easily using tabular and graphical reports and take appropriate actions.

This component allows the creation and administration of work step catalogues. Aside from work step code and name, instructions as well as drawings or other attachments can be specified for each work step. It is also possible to define which technical data has to be recorded when executing a work step.

Set up work steps can be used to create maintenance plans and work sequences for repairs. For each vehicle and vehicle configuration individual maintenance plans can be created based on the linkage between work steps, part type catalogues and product structures. Defined work steps and maintenance plans can be planned and commissioned using the Measure Management.

An integrated version control permits monitoring all changes including a release process. The version control takes into account the work step itself as well as the maintenance plans. Changes on work step level will inform the user automatically regarding effects in maintenance plans.

If the software is delivered with the VPI preconfiguration for VPI 08 by Sternico, all work steps defined by VPI will be available. The Sternico Software Assurance guarantees to maintain the software on the latest version of VPI 08.

The central function of this component is recording and managing defects. Different functionalities are available depending on the application area.

A maintenance workshop or a TOC/RU can record and classify defects. Furthermore, it is possible to define repair procedures based on work step catalogues which can be accessed during the recording of defects. This way, the list of work steps to be executed for a maintenance procedure can be extended by those work steps necessary to remove the defect. The collected data can be transferred to the ECM/keeper.

An ECM/keeper can receive notifications of defects on rolling stock from a TOC/RU or a maintenance workshop or create defects manually. COMAP allows classifying defects for analyses and follow-up procedures and offers a management to avoid future defects. Compensations can be managed adding costs and assigning responsibilities.

The Material and Spare Part Management extends the functionalities of part catalogues by information about quantity/stock, minimum quantity in stock as well as information about the storage location. Within the work step catalogue it is possible to assign material to a work step.

ECM/keeper can use the Material and Spare Part Management to control the replacement parts and material to be provided in different maintenance workshops. Maintenance workshops profit especially from the linkage with the product configuration and the data recording.

This component is used to plan shifts and qualifications of personnel. The shift planning in COMAP allows the administration of different shift rhythms and the assignation of personnel to shifts. Using week plans and a long term planning detailed shift plans can be created.

Qualifications and necessary trainings can be assigned to personnel and administrated. By linking qualifications to work steps COMAP ensures that sufficiently qualified personnel can confirm the completion of work steps. COMAP monitors as well if a worker can maintain his qualification due to the times he executed a work step in a set time frame.

Additionally, COMAP can be used to request over times for or relocation of personnel using a workflow process including approvals from works council.

The component Positioning allows adding location information to products as well as the history preservation. Depending on the type of product and type of position a variety of processes can be represented. For example, the complete storage movements can be visualized for a stored component like a distributor valve.

This component allows planning workshop schedules and workshop capacities. Visualize, plan and control measures and orders including internal and contractual lead-times.
Manage and control all events occurring during maintenance, which have effect on lead-times. Such an event could be missing material, which results in a state “Waiting for material X”. This state affects the actual lead-time negatively which may lead to an extension of the contractual lead-time.
Communicate events digitally between asset owner and workshop to inform e.g. about missing material and interrupted maintenance processes.

New build and modification projects can be administrated in the component Project Management. Products can be assigned to projects which can be scheduled using the component Measures Management. This allows for example the modification of brake pads for a group of waggons within a project. Each measure resulting from a project is tracked and the process can be supervised.

This component allows managing contracts between lessor and lessee as well as management mandates. A contract contains terms and conditions such as rates or validity periods for assets (e.g. locomotives or wagons). It is possible to configure contract chains and parallel lease of assets beside the simple case of direct lease.

Management mandates control the responsibilities given by the asset owner to the asset administrator. This includes e.g. ECM duties or ordering services from workshops in the name of the asset owner.

The operating data management is divided in two parts. On the one hand it provides the interfaces and services, for retrieving the operating data from the assets (e.g. locomotives). The services have been developed regarding availability and scalability so that can be transferred reliably in case of larger fleets and numerous operating parameters. The operating parameters include parameters like operating hours, mileage, oil temperature etc. as well as geoinformation and error messages or conditions.

On the other hand the component provides the possibilities for evaluating and processing the collected information. For example, fault conditions can be set in relation to selectable operating parameters. Load spectrums can be formed and these can be used for the maintenance planning. Repair measures can be derived and performed from these parameters.

The Rule Designer serves the quality assurance of technical data recorded or imported. Templates can be created with the designer that define how technical parameters of a product are linked together. For example, a rule could be established which defines that only a certain type of wheel sets X can be installed in bogies of type Y. If this rule gets violated while entering data or importing data, COMAP impedes saving invalid data.

The user can define as many rules as needed and connect them via logical links. In addition, mathematical operations can be used to verify, for instance, tolerances:
|Diameter wheel A - Diameter wheel B| < 1mm

The configuration is being carried out using a graphical user interface which allows addressing all structure elements, attributes, selection lists and parts.

Assuring the data quality when using digital data Exchange plays a central role for ECM/keepers. By using digital data Exchange with maintenance workshops many manual tasks will not be applied anymore, and part of the conventional quality assurance is reduced automatically. To build an efficient process that assures high quality, an automated validation of data using a proper rule based system is necessary.

Aside from existing checks for errors, maintenance Workshops can assure that errors while entering data will be reported to the user instantly using the Rule Designer. This guarantees a high data quality directly at the beginning of the process chain.

The web portal gives possibilities to analyze data in the software and graphical plotting of data. Different data sets can be connected and configured such that the individual Evaluation of data is possible. Dashboards can be created as Websites to show data in a graphical manner and in form of tables. These websites can be used in the local intranet or integrated into web portals for clients. The management and clients Profit from relevant live data evaluations.

The Report Configurator allows integrating individual Reports and protocols in COMAP which can be generated at the click of a button. Any PDF document with data fields can be uploaded as a report template and then be used.

PDF templates imported to COMAP can be linked to technical data, master data or orders by a report configurator. To link the data fields, the configurator supports a variety of functions to fill the report/protocol appropriately. These functions can be used to model very complex reports. This way a report is created that can be filled with live data at a click of a button. Specific customer report templates can be configured for each report. This allows, for example, creating the Operating Authorization reports for client A and client B which differ only in a few data fields easily.

If customers are assigned to products using the Order Management, COMAP can create all documents needed for a specific order at one click. The documents generated will be linked to the product, and archived with the technical structure and sent to the customer electronically via VPI 08.

Additionally, COMAP includes the released Standard VPI protocols like the Operating authorization or the Wheelset repair log. These can be filled with data from the COMAP database and generated into PDF files.

This component allows to administrate all measuring Equipment in the maintenance workshop. For each measuring device data like measuring units and measurement range can be specified aside from master data. Attachments like photos and documents can be stored as well as departments can be assigned to each measurement equipment. In addition, the calibration intervals of equipment is supervised. All calibration processes are version controlled with the relevant data.

A measuring equipment can be assigned to an attribute in the Structure Administration. In this case the software checks if measuring units of the device and the attribute coincide. This will influence the behavior of input fields in data recording and it can be guaranteed that a measuring equipment is specified. To assure a high data quality the user can only select among measuring equipment which is assigned to him and is calibrated at the time.

The assignment of measuring equipment to the data recorded allows printing those device numbers on protocols which the data is listed on. It is also possible to analyze data by listing, for example, all measurements of a specific measuring Equipment in a specific timeframe. This way all products that have been measured by a measuring equipment can be identified.

Webservices can be used to connect external systems. They can be created and configured freely via the graphic user interface. The technical data and the order in which the data has to be sent or accessed through the new connection can be defined by the user.

This way it is possible to exchange data with other systems, such as ERP systems or manufacturing machines which leads to a high software integrity and thus, to an ideal dataflow within the company. For example, an ERP system could access the technical data which is needed for order processing automatically from COMAP.

The component Plugins allows COMAP to integrate specially created function blocks, so called Plugins. A Plugin includes a specific user interface as well as an interface to machines and can be placed directly into a work profile. This way, data from machinery can be accessed directly from data recording. This procedure is especially suited for machinery without its own user interface like torque wrenches.

Additionally, a remote operation of a machine can be realized from within a work profile. For example, a coining machine can be connected to label wheelset marks. The worker can transferall relevant data to the machine and execute the labelling process. A Plugin has to be created for its specific usage by Sternico.
