First I simulate it,
then I put it into production.

Python, test suite that runs on every modification. No release without green tests — applies to Telegram bots, webapps, and backend in the same way.

plcsim It is a soft-PLC that emulates a real PLC (IEC 61131-3: ST and Ladder) via browser. I write and verify the logic — valves, timers, alarms, state machines — without risking a plant shutdown or an incorrect command on real hardware.

Once verified in simulation, the logic moves to the real PLC (Delta or compatible) via Modbus — same protocol, same addresses, no rewriting required.

Once on-site, Vedetta it reads and writes to the same Modbus tags: live dashboard, history, alerts via Telegram. The same plant, controllable from anywhere.

The plant is described only once in a text file: valves, motors, instruments, alarms. From there I generate the program for Siemens TIA Portal and for Delta ISPSoft, with identical functions and addresses. Changing brands does not mean rewriting everything.

I use AI agents for repetitive tasks, but nothing enters a project unless it passes automatic testing: hundreds of test cases compared against specifications, followed by bench testing with real PLCs. Faster, without lowering standards.
