Write Ladder and Structured Text in CODESYS and control realistic digital twins in SIMUMATIK, from logic circuits to a complete can filling and labelling line. Free, and no PLC hardware needed.
“I have done many courses on PLC programming, but the one I did through Code and Compile was definitely my favorite.”
SIMUMATIK gives you the machine. CODESYS gives you the PLC. You write the logic that brings it to life.
Run realistic 3D machines in your browser, with no installation.
Link the CODESYS soft PLC to the twin through the SIMUMATIK gateway.
Solve 13 logic circuit exercises and watch each one run on the twin.
Write the same logic in ST and learn when each language fits best.
Control conveyors, sensors and a filling station in a real industrial sequence.
Add sealing and labelling and coordinate a complete production line.
What a digital twin is, how SIMUMATIK works and how it connects to CODESYS.
Exercises 2.1 to 2.13: solve logic tasks in Ladder and ST and test them on the twin.
Automatic can filling, then sealing and labelling, the way real packaging lines run.
More free videos, and how to get your own SIMUMATIK license to keep building.
One complete lesson is open to everyone. Want more? The SIMUMATIK Academy has free videos too.
Solve your first eight logic exercises and watch the twin respond.
