Course project, about 14 hours

A hillside hotel's water and sewage plant: LOGO! 8 for the tanks and garden, S7-200 SMART for the STP

Design, program, test and document two small control systems for one hotel. A LOGO! 8 fills the rooftop tank from the sump and waters the garden on a weekly timer. An S7-200 SMART runs the sewage treatment plant's blowers and sludge pumps on timed cycles, with a dissolved-oxygen probe. You deliver both programs, your own I/O lists and one test record. The sample pack shows what a small contractor hands over when the client is a hotel and not a factory.

Practise what you learn in the free 3D lab

Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.

Common questions

Is LOGO! a PLC?

Siemens calls it a logic module. It programs like a small PLC in FBD or LAD and is the right tool for building and small-machine tasks; the S7-200 SMART modules show the step up to a compact PLC.

Do I need hardware?

No. The LOGO!Soft Comfort demo simulates every block. A LOGO! 8 starter kit is inexpensive if you want to wire things.

Some source lessons are members-only. Are they included?

No. Fourteen members-only analog lessons from one series were left out; the analog module uses public lessons from two other creators instead.

Why is the S7-200 SMART here?

It is the natural next step from LOGO! for small machines in China, India and the other Asian markets where it is sold, and its free tool makes the basics quick to learn.

Is the Siemens Small Controllers: LOGO! 8 and S7-200 SMART course really free?

Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.

What certificate do I get, and is it a Siemens qualification?

Do I have to use the lab?

No. The lab is optional practice. You can skip it whenever you like, and it never blocks your progress, the final assessment or your certificate.

Is the lab free?

Yes. Every lab level for this course opens in your browser, free, with nothing to install.
