PLC Programming in Saarland

PLC programming, control system retrofits and commissioning for plant operators and machine builders from Merzig to Homburg.

Prybisch Automation is an engineering office in Luxembourg for Siemens automation (TIA Portal, WinCC Unified, retrofits) and provides automation engineering in Saarland, mainly for steel, recycling and the beverage industry. Saarlouis is about 40 minutes from our head office in Stadtbredimus.

Automation engineering in Saarland

A typical Saarland plant runs on S5 or S7-300 controllers whose offline project is missing or no longer matches the installed state. We migrate them to S7-1500 or S7-1200 in TIA Portal and replace old operator panels with WinCC Unified. If symbols are missing, we reconstruct the program from the running PLC.

For machine builders and engineering teams short on capacity, we take on defined packages: program sections, HMI, safety technology or commissioning at an end customer's site.

Every project starts with a functional specification that serves as the benchmark for program, testing and acceptance. We test program and HMI in simulation before the plant stops, so the on-site window is reserved for conversion and commissioning. At the end you receive a commented TIA project, test reports and documentation in standard formats.

Frequently Asked Questions

How far is Saarland from Stadtbredimus?

From our head office in Stadtbredimus, driving time is about 35 minutes to Merzig, 40 minutes to Saarlouis and Dillingen, 50 minutes to Völklingen and 65 minutes to Saarbrücken. On-site appointments can therefore be arranged at short notice.

Which industries do you serve in Saarland?

Mainly steel, recycling and the beverage industry, plus machine building. We also have project experience with automotive suppliers, in water and wastewater and in waste-to-energy.

Can you step in for commissioning at short notice?

Yes, if the schedule allows. We take on commissioning for machine builders facing capacity bottlenecks, in Saarland as well as at end customers abroad. How short the notice can be depends on ongoing assignments.

Do you work to our standards?

Yes. We adopt your block libraries, naming conventions and HMI templates and deliver program sections that fit into your project. Where no standards exist, we propose a structure and document it.

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.
