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.
One point of contact. Your entire automation project.
We guide your project from concept through commissioning – new plants as well as retrofits of existing controllers (S5/S7-Classic to S7-1200/1500, HMI to WinCC Unified). Based in Luxembourg: on site at short notice in Luxembourg, Saarland and the Trier region, projects in Switzerland and across the DACH region, commissioning worldwide.

What we solve for you
From troubleshooting a single controller to automating a complete plant
K02
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.
K03
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).
K04
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.
K05
Process Control & Regulation
PID control, analog and digital control for pressure, temperature, flow and level. Process optimization and fine-tuning for stable production processes.
K06
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.
K07
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.
K08
AI-Assisted Data Analysis
Looking at it from the automation side, we show what your plant data can be used for, and then we build it: data access via OPC UA, dashboards, fault and downtime analysis, reporting. AI evaluates the data read-only; the PLC stays deterministic.
How we work: engineer + AI agents
We work in a hybrid way: the engineer designs the solution and sets the structure and style, while AI agents take on part of the routine work. Program, HMI and documentation are ready sooner, and the engineer keeps the direction.
“We” means David Prybisch as the responsible engineer, working with a well-established set of AI agents. He directs the agents, checks every result and feeds corrections back. Decisions and sign-offs are his to make.
The process
AI-assisted engineering
Clarifying requirements
We start by clarifying sequences, interfaces and constraints with you. Depending on the project, this leads to a functional specification; often the requirements specification, schematics and existing program are enough to work from.
Setting structure and style
The engineer defines the program structure, programming style, tag naming and screen concept. These rules are the framework the AI agents work within.
Program and HMI, AI-assisted
The PLC program and HMI are built by the engineer together with AI agents. The AI takes on part of the routine work, such as recurring blocks, tags and screens, or translating existing code to the target platform. That speeds up the build.
Review and rework
The engineer reviews the program and HMI in full and passes improvements back to the AI agents. A first draft rarely fits straight away, so this loop continues until both follow the defined structure and style.
Testing in simulation
The PLC program and HMI run together in simulation and are tested with AI assistance: sequences, edge cases and faults, as well as the interface between the two. Every tag has to arrive correctly on screen, every button in the controller. The results are logged.
On-site commissioning
The engineer downloads the program to the real controller, tests automatic mode, HMI and safety functions on the plant and sees it through to acceptance.
What you gain
More testing
Sequences, edge cases and faults are run through in simulation before the plant is built. Errors surface at the desk, not during commissioning.
Better groundwork
I/O lists, tag tables and program drafts are ready earlier. More of the engineer's time goes into design, review and coordination.
Documentation that did not exist before
Functional specification, comments and test logs are produced alongside the project, including for existing plants whose documents have gone missing.
Packages to get started
Fixed price after review
Clearly scoped services: we review your documents first, then quote a fixed price.
Schematic inventory analysis
I/O list and tag table from your PDF drawing set, as a basis for programming or a retrofit.
Example: a 51-page schematic turned into an I/O list and tag table in about eleven minutes.
Re-documentation
Functional specification derived from existing code, including S7-300 STL without symbols.
WinCC Unified screen package
Screens, alarms and tags derived from the PLC structure, tested in simulation.
Retrofit check
Effort estimate and hardware mapping for moving from S7-300 to S7-1200 or S7-1500.
Your project data
Project data is never used to train AI models. We work on our own systems rather than in public chat tools, agree the data flows with you before the project starts and sign a non-disclosure agreement (NDA) on request.
Project Areas
New development, retrofit, and technical support – with proven project experience
New Development of Production Lines
From concept phase to commissioning – PLC programming, safety concepts and material flow integration for new automation solutions.
View referencesRetrofit & Modernization
Migrate S5 and S7-Classic to S7-1200/1500, upgrade HMIs from WinCC Flexible or Comfort to WinCC Unified – screens rebuilt (partially AI-automated). Also possible without symbols, if online snapshot and scanned E-Plan are available.
