Machines, industrial systems, robots and construction equipment often remain in service for many years. Their electronic components, controls, supply chains and software versions move much faster.
This calls for resilient component supply in mechanical engineering: critical parts need to remain available and ready for production, maintenance, retrofit, aftermarket supply or re-manufacturing – from individual electronic components to control units and electronic assemblies.
btv technologies combines supply, protected storage, active component care and component services. For connected systems, btv SEEL® additionally helps protect microcontroller programming and document device identities and process steps in a traceable way.
When machines and electronics follow different cycles
Machines, industrial systems and construction equipment are designed for long operating lives. Electronic components, control units, software versions, supply sources and production sites follow their own cycles.
Sometimes a component is discontinued. Sometimes service demand changes, inventory coverage is no longer sufficient or a control unit needs to remain functional for later use. Connected machines also create requirements for firmware, device identity and traceability.
The goal is not to force one particular solution. The goal is to assess the specific supply situation early and protect, provide and document components so that machinery, service and the supply chain remain manageable.
Keeping electronics available throughout the machine lifecycle
A machine, industrial system, robot or construction machine can remain in the field for many years. Microcontrollers, memory devices, power semiconductors and other electronic components may become unavailable much earlier. At the same time, variants, software versions and demand patterns change throughout the product lifecycle.
For reliable spare parts supply in mechanical engineering, the availability of critical electronics determines whether maintenance, repair, retrofit and re-manufacturing can remain viable throughout the planned service life. Component discontinuation is only one possible trigger. Restricted availability, changing quantities or new service requirements can also require an early decision.
btv helps manufacturers structure supply for critical components and implement the required operational processes – aligned with production, service and aftermarket demand.
Supplying spare parts, retrofit and re-manufacturing predictably
Series demand can often be planned. Spare-parts, retrofit and service demand, by contrast, arises over many years, often in small quantities, across different variants and not always in the expected pattern.
For the spare parts supply of machinery and construction equipment, looking only at the original series is not enough. It requires supply logic with transparent inventory, clear call-offs and components that are available and ready for maintenance, repair, modernisation or re-manufacturing.
Keeping control units and assemblies functional
For machines, robots and construction equipment, simply storing electronic components is not always enough. Control units and electronic assemblies can require a coordinated protection and care concept throughout long storage periods – for example controlled storage conditions, documented storage cycles and, where technically appropriate and agreed, powering concepts and functional checks.
This helps keep components available and ready for maintenance, retrofit, aftermarket supply or re-manufacturing. For specific questions, an independent testing provider can be involved.
Programming connected machinery securely and traceably
For connected machinery, robots and construction equipment, programming becomes part of product security. Firmware, cryptographic keys and individual device identities need to be placed on microcontrollers in a controlled way. At the same time, it must remain traceable which component entered the supply chain with which programming and certificate status.
This applies to machine controls, robotics, telematics systems and remote-maintenance solutions. Products with digital elements may fall within the scope of the Cyber Resilience Act where their intended or reasonably foreseeable use includes a direct or indirect data connection to a device or network.
What belongs together should work together
Supply, storage, preparation, programming and logistics are often managed across different teams and service providers. Every additional handover creates coordination effort and can fragment information about inventory, processing status and material movements.
btv technologies connects the services that are relevant to your specific situation in one coordinated model. You decide which building blocks you need. btv manages the implementation through clearly defined interfaces – from supply through Storage and component services to secure programming and documented provision.
The result is not a standard package, but a supply-chain structure in which processes, responsibilities and information fit together.
btv TAK®: Structuring supply and call-offs for selected requirements
btv TAK® is not a fixed standard package for every bill of materials. It is configured around the specific components, product lines and supply-chain requirements of each customer.
With more than 70 modular services, btv TAK® can combine the elements that are relevant in the individual case – from component logistics, storage and call-off management to testing, programming, labelling, repacking, customs and transport management.
The advantage is that these steps are designed to work together. Rather than coordinating supply, storage, preparation and logistics across multiple providers and interfaces, you receive a model tailored to your supply chain, with clear responsibilities and traceable information on inventory, movements and process data.
Relevant when:
- production, service and retrofit requirements need to be considered together
- specific components, quantities or terms need a structured framework
- forecasts need review and call-off models need to be robust
- security of supply and cost efficiency must be assessed together
Storage: protected inventory – with btv LONGEVITY® where required
Not every sourcing or discontinuation risk calls for inventory. If another sourcing or product strategy is more economical, that option should be considered first.
Where selectively secured inventory is the best option, btv protects critical electronic components, control units and assemblies for the defined period and makes them available with appropriate documentation. This keeps components available for maintenance, aftermarket supply, retrofit or re-manufacturing.
The Storage service is structured in protection levels: from climate-controlled, ESD-safe and FM Global fire-protected storage through long-term storage to btv LONGEVITY® for particularly demanding components and long storage periods. Depending on the protection level, storage horizons range from a few years up to 50 years.
For critical electronics, protection measures, documented storage cycles and the necessary component care can be aligned with the planned later use. Where required, powering concepts, functional checks and external analyses can be incorporated. Storage can also be distributed across multiple fire compartments where needed. btv’s storage locations in Unna and Werl provide additional options for inventory and call-off planning.
Relevant when:
- a component, control unit or assembly cannot be replaced at short notice
- long service, spare-parts or retrofit periods need protection
- the functional condition of stored electronics must be actively considered
- inventory needs to remain protected, documented and available on demand
- the storage strategy needs to consider multiple fire compartments or locations
Component services: prepared for production, retrofit and service
Procurement is not the final step for every requirement. Components often need testing, programming, labelling, packaging or preparation in a defined format – for a production line, retrofit, repair, re-manufacturing or a specific site.
btv combines these steps with supply so that parts arrive where they are needed and in the form in which they are required. This applies to electronic components in mechanical engineering as much as to robotics, control technology and construction equipment.
Relevant when:
- components need testing or programming before use
- labelling, packaging or taping improves process reliability
- material needs preparation for different plants, variants or service channels
- new or changed material flows need operational implementation
btv SEEL®: Programming, device identity and evidence
For connected machinery, simply loading firmware is not enough. The programming process must protect sensitive firmware and keys, respect the customer’s control of its own PKI and provide clear documentation.
btv SEEL® processes encrypted firmware in volatile memory within the programming environment. With btv SEEL® INTERCONNECT, the customer’s PKI remains under the manufacturer’s control. btv SEEL® UNLIMITED documents individual device identities and process steps with cryptographic signatures.
This creates an audit trail for programming, certificate allocation and traceability at component level – particularly relevant for connected machinery, robotics, distributed manufacturing and demanding security or compliance processes.
Relevant when:
- machines, robots or construction equipment need individual certificates or device identities
- firmware and cryptographic keys require protected processing
- production spans multiple sites or partners
- programming data and certificate allocation need auditable documentation
Cybersecurity begins before deployment
The Cyber Resilience Act applies to products with digital elements where they connect directly or indirectly to a device or network. It can therefore be relevant to connected machinery, robotics, remote maintenance, telematics and digital control systems.
Responsibility for end-product conformity remains with the respective manufacturer. However, the programming process is a critical part of the evidence chain: How does firmware reach the device? How are keys protected? Which certificate is assigned to which component? Which batch is affected by a security incident?
btv SEEL® helps manufacturers make these steps traceable from the point of programming. This is not a blanket promise of compliance; it is a documented basis for the manufacturer’s own security, quality and compliance processes.
Important for planning: CRA reporting obligations for actively exploited vulnerabilities and severe incidents have applied since 11 September 2026. The Regulation otherwise applies from 11 December 2027.
A typical project path
1. Understand the starting point
We consider affected components, control units or assemblies, product lifetimes, supply capability, variants, service requirements and existing sourcing or programming processes.
2. Align supply and protection concepts
Supply situation, inventory coverage, selectively secured inventory, Storage, btv LONGEVITY®, component services or an adjustment of material flows: together, we align the implementation that fits the commercial and operational context.
3. Set up the right implementation
We organise supply, protection concepts, call-offs, active component care, preparation, programming and logistics around your requirements – from an individual component to a control unit or electronic assembly.
4. Keep information available
Material movements, storage cycles, programming and the required process data remain traceable. This provides a reliable basis for operational management, quality processes and audits.

FAQ – direct, honest, to the point
This depends on product lifetime, the component or assembly, the planned service period, quantities and available sourcing options. For individual critical components, selectively secured inventory can be appropriate. The key is that storage, call-off and provision fit maintenance, aftermarket supply, retrofit or re-manufacturing requirements.
btv LONGEVITY® can be relevant when critical electronics need to remain protected and available throughout particularly long machine or service periods and replacement would involve significant effort. The protection concept is aligned with the component or assembly, storage period and planned application. Depending on requirements, documented storage cycles, powering concepts, functional checks or external analyses can be included.
Yes, provided that the protection concept, storage conditions and necessary care fit the specific unit. For control units or assemblies, this can go beyond storage alone – for example through controlled conditions, documented storage cycles and, where technically appropriate and agreed, powering concepts and functional checks.

When a source is constrained, demand changes or components need to be secured for maintenance, service, retrofit or re-manufacturing, btv supports structured supply and operational implementation. This can include inventory and call-off concepts, Storage, btv LONGEVITY®, component services, logistics and documented provision.
Technical evaluation and approval of an alternative component, as well as any design decisions, remain with the manufacturer. btv supports the operational implementation of the selected supply and process solution.
btv SEEL® supports protected, documented programming of microcontrollers. Encrypted firmware is processed in volatile memory. The customer’s own PKI can remain connected and under its control; individual device identities and process steps can be documented cryptographically. This creates a traceable basis for security, quality and compliance processes.
The CRA applies to products with digital elements and to the responsible economic operators, rather than to a programming service in isolation. End-product conformity remains the manufacturer’s responsibility. With protected programming, PKI integration, device identity and an audit trail, btv SEEL® can provide relevant evidence for the manufacturer’s processes.
