PLC Programming and Retrofits in Merzig-Wadern
Control engineering for ceramics, machine building and existing plants in Merzig, Mettlach and Losheim am See.
Prybisch Automation is an engineering office in Luxembourg for Siemens automation (TIA Portal, WinCC Unified, retrofits). The Merzig-Wadern district borders Luxembourg: from our head office in Stadtbredimus it is about 20 minutes to Perl and 35 minutes to Merzig.

Automation engineering in the Merzig-Wadern district
The district combines ceramics production, machine building and mid-sized manufacturing, often with plants that have grown over decades. For such plants we replace S5 and S7-300 controllers with S7-1500 or S7-1200 in TIA Portal and move operator panels to WinCC Unified.
New plants we accompany from the functional specification through PLC programming to commissioning, with program and HMI tested in simulation beforehand. Because distances are short, commissioning can be split into several short visits that fit around your production.

Frequently Asked Questions
How quickly can you be in Merzig, Mettlach and Losheim am See?
From our head office in Stadtbredimus, driving time is about 20 minutes to Perl, 35 minutes to Merzig and 60 minutes to Wadern; Mettlach and Losheim am See lie within this range. How fast we actually reach you in case of a fault depends on ongoing assignments.
Do you know the district's industries, such as ceramics and machine building?
Yes. From our projects we know ceramics and refractories, machine and plant building, food and beverage, and recycling. Typical are plants that have grown over time, with controllers from several generations that are moved to TIA Portal step by step.
Do you also take on smaller jobs?
Yes, from a change to a single machine to a complete line, as well as troubleshooting on existing plants. Small jobs also start with a short review and an agreed scope.
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.
What does a move to WinCC Unified bring?
WinCC Unified is Siemens' current HMI platform and the successor to WinCC flexible and the classic Comfort panels. We derive screens, alarms and tags from the PLC structure and test them in simulation. The switch can often be done in the same shutdown as the PLC retrofit.
