Modernisation and existing plants
A plant outlives its control system. When components are discontinued or a conversion is due, success is not decided by the spare part but by whether the planning knows the plant as it really is today.

One contact, not a distribution list
Whoever takes your project also works on it.
Your CAE system, not ours
EPLAN, WSCAD, ELCAD — with your part master.
Existing plants are our everyday work
Plant runs, documents do not match. That is where we start.
Capacity without a permanent post
Design capacity when you need it.
When this service is needed
- Control components are discontinued; the spare parts supply is getting tight.
- The plant is to be extended or converted – based on documents that are old.
- Production can hardly stop for the conversion.
- The plant contains historical changes that were never documented.
- Different parts of the plant follow standards from different decades.
Result
- A conversion planned on the real plant, not on its paper state
- A list of the deviations between drawing and plant
- Steps your own maintenance team can carry out
- Documentation that is correct after the conversion – the basis for the next one
Adjacent trades
- Control cabinet building
- PLC programming
- Installation
- Commissioning
- Inspections
We do not carry out these trades ourselves. On request we bring in specialised partners and coordinate the interfaces – you keep a single technical point of contact.
Whether a conversion succeeds without interrupting production depends on the plant, its condition and the downtime windows – we say so beforehand instead of promising it. What planning can do: cut the steps so interruptions stay short or fall into stops that are planned anyway.
Process
How we work together
- 01
As-is survey
We reconcile the documents with the plant and find what has changed unnoticed over the years.
- 02
Deviations and effort
You get the list of deviations and know what the backlog costs before placing the order.
- 03
Concept in steps
Replacement, reserves, sequence: the conversion is cut so the operation can absorb it.
- 04
Design
The new technology is planned and worked into the existing documentation.
- 05
Execution and feedback
The steps are carried out – by your maintenance team or coordinated partners – and documented.
Questions about this service?Show contact

Replacing discontinued components is the easy part of a retrofit. What tips such projects over are the changes of the past twenty years that never flowed back into the documents: the extra terminal, the relocated drive, the jumper somebody fitted and nobody noted. Anyone planning from the old drawings is planning on a plant that no longer exists in that form.
That is why the as-is survey comes before the concept. We reconcile the existing documents with the plant and first deliver a list of the deviations. Only then does the conversion concept follow: what gets replaced, which reserves are still available in the cabinets, and in which order it can be carried out without stopping production longer than necessary.
We cut the conversion steps so your maintenance team can carry them – with many customers they execute the steps themselves. Every change from conversion and commissioning is fed back into the documentation. What remains is a plant that runs and a set of documents that matches it, forming the basis for the next conversion.
Frequently asked
Our drawings are outdated – is that a problem?
It is the normal case, and exactly why every retrofit starts with the as-is survey. Reconciling drawings and plant is part of the service, not your prerequisite.
Can the conversion be done without interrupting production?
That cannot be promised across the board. It depends on the plant, its condition and the available downtime windows. We cut the conversion so interruptions stay short or fall into planned stops; in individual projects it succeeded without interruption.
Who carries out the conversion?
That is your choice. Many customers execute the steps with their own maintenance team – we plan them accordingly. Where trades are missing, specialised partners can be brought in; we coordinate the interfaces.
