Automation engineering in Trier and the Eifel
For companies in the Trier region our main work is retrofits: S5 and S7-300 controllers to S7-1500 or S7-1200 in TIA Portal, old operator panels to WinCC Unified. We rebuild the program in FBD and LAD with meaningful symbols. If the offline project or symbols are missing, we reconstruct the program from the running PLC.
Companies with sites in Luxembourg, Saarland and Rhineland-Palatinate get the same process everywhere: one contact, a consistent program structure and the same documentation for every site.

Frequently Asked Questions
How far is it to Trier, Saarburg and Bitburg?
From our head office in Stadtbredimus, driving time is about 30 minutes to Saarburg, 40 minutes to Trier, 55 minutes to Bitburg and 80 minutes to Prüm. Konz, Schweich, Hermeskeil and Wittlich lie within this range.
Do you have experience with food and beverage plants?
Yes. For a beverage producer we brought ten individual plants together in a central WinCC Unified overview, read-only and without changing the plant programs. Commissioning took place in August 2026; the last plants follow once the site IT has cleared the network access.
Do you train our operators and maintenance staff?
Yes. After commissioning we train operators and maintenance staff at the plant. The functional specification, test reports and the commented TIA project stay with you, so your team can handle faults on their own.
Can you replace old S5 or S7-300 controllers?
Yes, it is our most frequent assignment. We migrate S5 and S7-300/400 to S7-1500 or S7-1200 G2 in TIA Portal and replace WinCC flexible and Comfort panels with WinCC Unified. The program is rebuilt in FBD and LAD so that your maintenance team can read it themselves when a fault occurs. Control cabinet and wiring can often stay in place.
What if neither an offline project nor symbols exist any more?
Then we reconstruct the program from the running PLC: symbols, comments and a description of the current state, for S5 and S7 Classic. If the circuit diagram is missing too, we work from scanned drawings. The result can go straight into a migration to TIA Portal.
