Siemens Brings Refurbished Automation Equipment to a Wider Market
Siemens has partnered with Sparepartsnow to expand access to refurbished industrial automation equipment in Europe.
The partnership adds manufacturer-refurbished Siemens products to the Sparepartsnow B2B marketplace. The initial portfolio includes drives, controllers, and HMI panels.
Siemens performs the refurbishment before the equipment reaches the marketplace. Therefore, customers can source used automation hardware through a channel supported by the original manufacturer.
This approach addresses a common issue in factory automation. Many plants still operate control systems that remain technically suitable after years of service.
Replacing every installed PLC, drive, or HMI can also require engineering changes. It may affect application software, wiring, commissioning procedures, and spare-part strategies.
For these applications, refurbished equipment can provide another lifecycle option.
Siemens Links Refurbishment With Industrial Automation Lifecycle Management
The partnership reflects a broader shift toward lifecycle management in industrial automation.
Factories often maintain Siemens PLCs, distributed control equipment, drives, operator panels, and other control-system hardware for long periods.
However, product availability can become difficult as platforms age. Original production may end before the surrounding machine or process reaches the end of its operational life.
Refurbishment can therefore support maintenance teams that need compatible replacement hardware without immediately redesigning an entire control architecture.
Siemens describes its refurbished products as previously used automation equipment restored to the original technical specifications and performance characteristics.
The distinction matters for engineers. Refurbishment does not mean adding new functions or increasing the original performance.
Instead, the objective remains restoring the equipment to its specified operating condition.
What Happens During the Siemens Refurbishment Process?
Siemens uses a standardized refurbishment process for qualifying automation products.
The process can include technical repair, replacement of worn components, required hardware updates, and required software updates.
Siemens also cleans the equipment and restores damaged housing components when necessary.
The company then performs functional and quality testing against its specifications and established quality requirements.
This process creates an important difference from ordinary used-equipment resale.
A conventional used PLC or drive may only receive a basic visual inspection. Manufacturer refurbishment applies a defined technical assessment and testing process.
For maintenance departments, that distinction can simplify the evaluation of replacement hardware.
Refurbished PLC and Control System Hardware Can Support Existing Plants
The potential value becomes clearer in long-running production facilities.
A machine may still depend on an established Siemens PLC platform because its application software already works correctly.
Replacing the complete control system could require programming changes, I/O verification, panel modifications, and production downtime.
A refurbished compatible controller can provide another option when the installed hardware requires replacement.
The same principle applies to HMI panels and industrial drives.
For example, a maintenance team may need a replacement drive for an established machine. If the surrounding motor, control logic, and cabinet design remain unchanged, compatible refurbished hardware may reduce the scope of the intervention.
Engineers must still verify the exact order number, firmware requirements, electrical ratings, communication interfaces, and application compatibility.
Refurbishment does not remove the need for engineering validation.
Drives, Controllers, and HMI Panels Form the Initial Portfolio
The initial Siemens portfolio covers selected drives, controllers, and HMI panels.
These product categories represent important components in factory automation systems.
Drives interact directly with motors and machine mechanics. Controllers execute automation logic and coordinate field-level signals.
HMI panels provide the operator interface for machine status, alarms, diagnostics, and process commands.
Consequently, the availability of replacement hardware can influence maintenance planning across several layers of a control system.
Siemens and Sparepartsnow plan to expand the product range and regional availability over time.
Cybersecurity and Compliance Remain Part of the Lifecycle Discussion
Industrial automation refurbishment also raises questions beyond physical condition.
Control-system hardware operates within electrical, functional, communication, and cybersecurity environments.
Siemens states that its refurbished products retain their original product characteristics. The company also addresses applicable safety, conformity, and cybersecurity requirements from the original market placement.
However, plant operators should still evaluate the complete system.
A refurbished PLC may be technically functional while the installed firmware remains unsuitable for a newer cybersecurity architecture.
Likewise, an older HMI may require compatibility checks with current engineering software.
Therefore, maintenance teams should evaluate the replacement part together with the surrounding control system.
Refurbishment Can Reduce Pressure on Industrial Spare-Part Strategies
Industrial maintenance teams commonly maintain spare inventory for equipment with long operating histories.
This strategy becomes harder when manufacturers discontinue older hardware families.
A refurbished marketplace can add another sourcing channel between new production and conventional used equipment.
That option can matter for plants operating legacy PLC, DCS, motion-control, or factory-automation systems.
The benefit depends on product availability, technical compatibility, testing requirements, and the plant’s maintenance policy.
Therefore, procurement teams should compare refurbished equipment with new, replacement, and retrofit options for each application.
Circularity Is Becoming More Relevant to Factory Automation
The Siemens and Sparepartsnow partnership also reflects a wider interest in circular industrial technology.
Industrial automation hardware contains electronic components, metals, plastics, and other resources.
Extending equipment use can reduce the need for immediate replacement of complete assemblies.
The environmental benefit depends on the actual refurbishment process, transport requirements, replacement components, and additional service life.
Therefore, circularity should be assessed across the complete equipment lifecycle rather than through refurbishment alone.
For industrial users, lifecycle extension can also support maintenance continuity.
Keeping suitable hardware available can help plants avoid unnecessary system changes when existing equipment still meets process requirements.
Practical Application: Maintaining a Legacy Siemens Production Line
Consider a production line that uses an established Siemens controller, HMI, and variable-speed drive system.
The machine remains mechanically suitable for production. However, one controller fails after years of operation.
A complete automation migration could involve hardware replacement, software conversion, cabinet work, testing, and commissioning.
A compatible refurbished controller could provide another maintenance route.
The engineering team would first confirm the exact order number and hardware configuration.
It would then verify firmware, communication interfaces, I/O requirements, and application compatibility.
After installation, engineers would perform functional checks before returning the machine to production.
This approach does not eliminate modernization planning. Instead, it can provide additional time for a controlled migration strategy.
Refurbished Automation Does Not Replace Modernization
Refurbishment and modernization serve different engineering objectives.
Refurbishment focuses on extending the useful service life of existing hardware.
Modernization usually changes the control architecture, hardware platform, software environment, or communication technology.
A plant may therefore use both strategies during different lifecycle stages.
For example, a refurbished PLC can maintain production while engineers prepare a larger migration project.
This staged approach can help separate immediate maintenance requirements from long-term automation investment.
The correct choice depends on equipment condition, production requirements, engineering resources, lifecycle status, and system compatibility.
Siemens and Sparepartsnow Could Expand the Secondary Automation Market
The partnership creates a direct connection between OEM refurbishment capability and a specialized B2B marketplace.
That model could influence how industrial users source discontinued or previously used automation hardware.
The initial European focus also provides a defined starting point for the program.
Siemens says the portfolio and geographic availability will expand progressively.
From an engineering perspective, the most important factor will be product-level availability.
Industrial buyers rarely need refurbishment as an abstract concept. They need a specific controller, drive, HMI, or spare module that matches an installed system.
Therefore, searchable part numbers, technical documentation, test information, and compatibility data will remain important to the success of this model.
Industry Perspective: Lifecycle Availability Matters as Much as Product Performance
From a maintenance perspective, industrial automation hardware has value beyond its original purchase date.
A controller can remain part of a validated machine architecture for many years.
When that controller becomes difficult to source, the plant faces a lifecycle-management problem rather than a simple purchasing problem.
Manufacturer refurbishment addresses part of this challenge by keeping selected equipment in circulation.
At the same time, engineers should continue to assess obsolescence, cybersecurity exposure, software support, and spare-part availability.
In practice, the strongest maintenance strategy often combines short-term replacement planning with longer-term modernization planning.
What This Means for Industrial Automation Buyers
The Siemens and Sparepartsnow agreement gives European industrial customers another route for sourcing refurbished Siemens automation products.
The initial offering covers selected drives, controllers, and HMI panels.
Siemens performs the refurbishment and testing before the products enter the marketplace.
For plants running established Siemens control systems, this model may support longer equipment lifecycles.
However, buyers should verify every replacement against the installed system.
Part number, hardware revision, firmware, electrical ratings, communication interfaces, software compatibility, and application requirements all deserve review.
As industrial automation moves toward longer and more managed lifecycles, refurbishment may become one component of a broader spare-parts and modernization strategy.
