What I solve for you
From PLC challenges to complete plant automation – my expertise for your success
PLC Programming
TIA Portal for S7-1200/1500(F) and STEP 7 Classic for S7-300/400(F). Structured programming, modular function blocks and complete documentation for functional testing and acceptance.
Functional Safety
Safety concepts per ISO 13849, ProfiSafe programming and Distributed Safety. Failsafe PLC solutions (S7-1500F, S7-300F/400F) with emergency stop cascades and validated safety logic.
HMI Visualization & SCADA Engineering
WinCC Comfort/Advanced and WinCC Unified with multilingual operator interfaces, recipe management and batch control. Including HMI migration: upgrading legacy WinCC Flexible and Comfort panels to WinCC Unified – screens are rebuilt (partially AI-automated).
Drive Technology & Motion Control
Parametrization of SEW, SINAMICS and Danfoss frequency inverters. Positioning, motion control and axis coupling for precise motion sequences in production lines.
Process Control & Regulation
PID control, analog and digital control for pressure, temperature, flow and level. Process optimization and fine-tuning for stable production processes.
Commissioning & Worldwide Support
On-site commissioning of production lines worldwide. Operator training, functional testing and final acceptance as well as support until successful handover to your production.
Program Recovery & Reverse Engineering
When only an online snapshot without symbols, without described DBs and without network comments remains: re-documentation of S5 and S7-Classic programs, AI-assisted. Also reconstruction from scanned schematics when the E-Plan is missing. On request directly combined with migration to TIA Portal.
AI Workflows & AI Consulting
AI workflows have been part of my daily engineering work for nearly a year: AI-assisted PLC programming in TIA Portal V21, WinCC Unified panels pre-generated with AI and manually refined, TIA Openness for automated workflows. AI as a booster for grunt work, diagnostics and hard problems. Consulting for plant operators and integrators.
