Automation engineering, end to end.
Independent support for machine and installation control systems, from the first concept through to commissioning. Everything is built in Siemens TIA Portal and Step7, using GRAFCET (DIN EN 60848) structured logic.
PLC Programming
Every program is written using the GRAFCET methodology (DIN EN 60848), so the logic follows clear steps and transitions instead of a maze of rungs nobody wants to touch. Documentation gets written as the program is built, not bolted on afterward, so the next person who opens the project can actually follow what it does and why.
- Siemens TIA Portal and Step7
- GRAFCET structure, step by step
- Documentation written alongside the code
Machine & Installation Design
I start with the process itself: what needs to happen, in what order, and where things could go wrong. From there I work out the hardware, the wiring concept and the control flow, so the electrical panel and the PLC program are designed to match each other from day one instead of being patched together afterward.
- Hardware and wiring concept
- Control flow mapped to the process
- Designed alongside the panel, not after it
Control System Optimization
Sometimes a machine already runs, it just does not run well. I go through the existing control system, find where the logic breaks down or slows things up, and rework it into something structured and reliable, without keeping the line down longer than it needs to be.
- Root cause analysis, not just patches
- Legacy logic rebuilt to GRAFCET structure
- Minimal downtime during the switch
Commissioning & Safety
Commissioning means walking through every safety-relevant scenario on-site, including what happens if a sensor drops out or a cable gets damaged. The system needs to fail safe every time, not just most of the time, so that gets checked before the machine goes into production, not after.
- On-site testing and sign-off
- Fail-safe scenarios checked, not assumed
- Handover documentation included
Four steps, one engineer throughout.
Concept & requirements
Before anything gets programmed, I need to understand the process itself: what has to happen, in what order, and where the real constraints are. Most of the important decisions get made here, not later.
Engineering & design
This is where the control architecture takes shape. Logic gets structured using GRAFCET (DIN EN 60848), and fail-safe behaviour gets built in from the start rather than added on afterward.
Programming & testing
The PLC program is written in Siemens TIA Portal or Step7 and tested in stages as it comes together, so problems get caught on the bench instead of on the machine.
Commissioning & handover
On-site commissioning covers every safety-relevant scenario, not just the easy ones to test. You get clear documentation at the end too, so the system does not depend on me being the only one who understands it.
