Replace your old control system with a new one, avoid unnecessary downtime
Do you operate a machine that still suits your needs, but its outdated control system and insufficient diagnostics are holding you back? We provide a complete overhaul of both the mechanical parts and the control system, including replacement of field instrumentation and cabling, as well as installation of a new control cabinet.
We have extensive experience, for example, with the transition from the SIEMENS S5 system to the new SIEMENS versions:
- Siemens S7 – 1200
- Siemens S7 – 1500
The result of the refurbishment is a functional machine with an up-to-date control system with a functional user interface, which allows you to reduce downtime to a minimum thanks to timely diagnostics.
Retrofit as an Alternative to Purchasing a New Machine
Retrofit and modification of existing machines represent an investment with the highest return and the shortest implementation time.
We specialize in machine retrofit and upgrades of production equipment. With our manufacturing experience, we offer retrofit as an attractive alternative to purchasing a new machine.
What We Modernize
- Mechanical retrofit: Renovation of mechanical components
- Control systems: industrial automation HW & SW: PLC hardware and software modernization
- Drives: Frequency converters and servo drives
- Electrical systems:New control cabinets, cabling, wire and terminal labeling, EMC / noise suppression, control cabinet cooling
- Compressed air distribution and control: Pneumatic terminals, air distribution systems, end devices
- Safety: Risk analysis, implementation of safety components, fencing and safety marking, validation of safety circuits
- HMI, operator panels and workstations: Ergonomics, control logic, alarm management, recipes
- Data acquisition and communication with higher-level systems / MES
An investment with the fastest return on investment (ROI)

We bring your machines back to life through retrofit
The result of the retrofit is a fully functional machine with a modern control system and an effective user interface, enabling early diagnostics and minimizing downtime. As a result, you gain:
- Complete renovation of mechanical components
- Replacement of electrical wiring and control cabinet
- Safety analysis and updated labeling
- Optimization of control elements
- Technical documentation and manuals
- Availability of spare parts and service
- Increased operational efficiency
- Fast and accurate diagnostics
- Minimal downtime, saving time and costs
- Extended equipment lifespan
When is a retrofit the right choice?
- The machine does not meet current safety standards
- Frequent downtime troubles you, or you just want to prevent it
- The machine is mechanically sound but technologically outdated
- PLC/HMI is obsolete, and the manufacturer has discontinued support
- Spare parts are not available
- Operators report non-ergonomic or difficult controls
- You need to increase performance or automate processes
