Engineering & Specification
Functional specification, safety matrix, hardware selection, network planning to NAMUR — the basis everyone refers back to later.
Services
Field-proven automation solutions
From PLC programming through commissioning to retrofit, program recovery and AI-assisted data analysis – engineering services for modern production lines in the Saar-Lor-Lux region.
Scope of services
Three areas, one point of contact. Channels with a branch lead to the full description.
Automation
Control, visualization, drives and commissioning — from the functional specification to acceptance.
A01
Retrofit S5/S7 → TIA Portal
S5 and S7-Classic to S7-1500 or S7-1200, WinCC Flexible and Comfort to Unified. The plant keeps running; the changeover happens in the shutdown window.
View serviceA02
Retrofit CODESYS → TIA Portal
WAGO 750/PFC and Beckhoff TwinCAT to S7-1500 with WinCC Unified. The existing code is read and documented; program and HMI are rebuilt in TIA Portal.
View serviceA04
PLC Programming
TIA Portal for S7-1200/1500 (incl. F), STEP 7 Classic for S7-300/400 (incl. F). Structured to IEC 61131, ProfiSafe included.

A08
Commissioning & Service
On-site commissioning worldwide, function testing, acceptance, operator training. Experience on four continents.
View serviceA09
Program Recovery & Reverse Engineering
When all that remains is an online snapshot without symbols: re-documentation from the running system, reconstruction from scanned circuit diagrams.
A10
PLC & Visualization for Panel Builders
You supply the cabinet and the installation, we supply the program, visualization, system test and commissioning. Your customer gets one complete project.
View serviceOT Security
Securing the automation layer up to the boundary with the office network. Corporate IT is not part of it.
B01
Zone and Cell Segmentation
Network structure of the automation layer, separation of individual plant cells and a controlled transition to the office network — instead of a flat network where every controller reaches every other.
B02
Remote Maintenance and Remote Access
A connection the plant establishes outbound, released on site instead of standing permanently open. Over cellular where no plant network is available — with a site assessment beforehand rather than trial and error.
B03
Hardening Controllers and Visualization
User and permission concept, firmware and patch levels, shutting down services that are not needed. Plus technical groundwork for NIS2 requirements at plant level.
Data Paths & AI
Making what the plant produces usable — in analysis, in reports, in the ERP.
C01
Plant Data & OPC UA
Opening up data sources in the controller and passing them upward cleanly — OPC UA, MQTT, database.
View serviceC02
AI-Assisted Data Analysis
Fault and downtime analysis, shift and maintenance schedules, machine data into ERP or dashboard.
C03
AI-Assisted Engineering
How our projects are built, in daily use rather than a test setup: program drafts checked against the functional specification, AI-assisted re-documentation, machine evaluation of technical documents. Review and commissioning stay with the engineer.

Frequently Asked Questions
Answers on retrofit, program recovery, AI-assisted data analysis and commissioning in the Saar-Lor-Lux region
What are your core service areas?
Commissioning of new production lines and retrofit of existing systems – both equally weighted. Based in Luxembourg, on site at short notice in Saar-Lor-Lux, projects in Switzerland and across the DACH region, commissioning worldwide. Engineering at a fixed price after review; commissioning is usually billed on a time basis (hourly or daily rates).
Which retrofit migrations do you offer?
S5 and S7-300/400 to S7-1200 or S7-1500 (Failsafe variants included) with TIA Portal, plus HMI retrofit to WinCC Unified (from WinCC Flexible, WinCC Comfort/Advanced or older touch panels). Complete package: program conversion, hardware migration, commissioning and operator training – with minimal downtime.
Can you recover a PLC program when no symbols remain?
Yes. Typical case: only an online snapshot available, data blocks not documented, no network comments. The basis for reconstruction is online snapshot + scanned E-Plan pages. From these we reconstruct symbols and documentation, AI-accelerated. Works for S5 and S7-Classic (S7-300/400). On request directly combined with migration to TIA Portal.
How does HMI migration to WinCC Unified work?
WinCC Flexible (S7-300/400 world) and WinCC Comfort/Advanced (the old TIA WinCC) cannot be auto-migrated to Unified – all screens must be rebuilt. AI-assisted workflows take the grunt work (pre-generating screens), followed by manual refinement. Often combined in the same retrofit step with the PLC migration.
What exactly does AI-assisted data analysis cover?
Looking at it from the automation side, we show what your plant data can be used for, and then we implement it: data access via OPC UA, dashboards, fault and downtime analysis and reporting. AI evaluates the data read-only; the PLC stays deterministic. What you end up with is analysis running in your plant, not a slide deck.
Which areas do you cover?
We are based in Stadtbredimus, Luxembourg, on the Moselle right at the German border. Within Saar-Lor-Lux we can be on site at short notice: Luxembourg, Saarland (Saarbrücken, Saarlouis, Merzig-Wadern), Rhineland-Palatinate (Trier, Saarburg, Bitburg) and Lorraine – from Stadtbredimus it takes approx. 35 minutes to Merzig and approx. 40 minutes to Trier or Saarlouis. Beyond that, we take on projects across the DACH region (Germany, Austria, Switzerland) and commissioning worldwide, with over 30 international commissionings on four continents so far. Projects in Switzerland are handled through remote engineering combined with on-site commissioning: PLC programming for projects in Switzerland.
