Course project, about 4 hours

Carton conveyor with emergency stop, overload and strapper interlock: contacts, coils and a signed FAT on an S7-1200

Design, program, test and document a small carton conveyor for a printing works. It has a sealed-in run request, an emergency stop input, an overload input and a belt that waits for the strapping machine to clear. All of it is built from contacts and coils. You deliver the program, your own I/O list and FAT record, and a hand-over note. The sample pack shows what a system integrator delivers for a job this size.

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.

  • Practise safely, so a mistake costs nothing.
  • The lab checks your work like a site test, so you know when it is right.
  • Free, in your browser, with nothing to install.

Common questions

How is this different from the full Siemens TIA Portal course?

It is the first eight modules of that course, the same lessons in the same order. It has its own short final assessment and its own certificate. The full course goes on to timers, counters, analog scaling, function blocks and a WinCC HMI screen over 22 modules. This one stops once you have written and proven your first ladder rung, which takes about three hours of video. If you want more, you continue into the full course from module 9 and nothing is repeated.

Why would I take the short one rather than the full course?

Most people who start a 22-module course never reach the end, and the certificate is earned at the end. This course gets a working program and a certificate into your hands in an evening or two. It is also the honest test of whether PLC work suits you before you give it six weeks.

Do I need to buy TIA Portal?

No. Siemens publishes a free 21-day trial of TIA Portal with S7-PLCSIM included. It needs only a free Siemens account to download. Modules 1 to 3 need no software at all, so do those first and install before module 4.

Do I need a real PLC?

No. Every exercise runs in S7-PLCSIM, the simulator included in the trial. Nothing in this course assumes you have hardware.

What kind of computer do I need?

You need a 64-bit Windows 11 Pro or Enterprise PC with administrator rights, at least 8 GB of RAM and 20 GB free on the drive. Siemens recommends 16 GB and an SSD with about 50 GB free. TIA Portal V21 no longer supports Windows 10 Pro; older versions such as V17 still install on Windows 10. It does not run on macOS or Linux. A Windows virtual machine works if you give it plenty of memory.

Is the Siemens TIA Portal in Three Hours course really free?

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

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

You get an EDWartens Certificate of Completion for the starter course when you pass the final assessment. It has a unique number anyone can verify on our site. It is not a Siemens credential and we will never describe it as one.

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.

What can I do after the Siemens TIA Portal in Three Hours course?

After the Siemens TIA Portal in Three Hours course: Explain what a PLC does, where it sits in the automation pyramid and why it replaced the relay panel; Describe the scan cycle and the process image, and say what happens to a signal shorter than one scan; Wire a sinking or sourcing sensor to an S7-1200 input without guessing, and say what fail-safe means. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.

What software and hardware do I need for the Siemens TIA Portal in Three Hours course, and does it cost anything?
