- Free in the United States, as everywhere, and self-paced: lessons, notes and the final assessment are open at any hour, so your time zone and shift pattern do not matter.
- The optional certificate for learners in the United States is a one-off US$23.99. What you get for it
- Plants across the Americas most often run Allen-Bradley, Siemens and Inductive Automation; each has its own free course to take next.
- See automation and engineering jobs in the United States, and what the industry looks like in Houston, Detroit and Chicago.
- EDWartens also has a regional site for the United States, for classroom training and local support: edwartens.com/us.
The course project 路 about 18 hours
Mall booster pumps and generator changeover on an easyE4: pressure control, load shedding, time switches, remote display
Design, program, test and document the utility control of a four-storey mall in Lagos on one Eaton easyE4: a duty/standby hydro-pneumatic booster set on an analog pressure transmitter with alternation, anti-cycling, dry-run and pump-fail logic; the mains-to-diesel-generator changeover with feedback-checked breaker sequencing, load shedding and cool-down; fa莽ade, signage and car-park lighting on a weekly time switch and the astronomical clock; a remote touch display in the security room; and a data logger on the microSD card. You deliver the easySoft 8 project, your own I/O list, interlock list and FAT record. The sample pack shows what an integrator hands a mall's facilities department.
Sample document pack, 7 documents, filled in for the scenario
- FDSFunctional Design Specification: Utility Panel UP-1, Booster Pumps and Generator Changeover
- I/O listI/O List: Panel UP-1 (easyE4 base and expansions)
- BOMBill of Materials: Panel UP-1 and Field Devices
- Interlock listInterlock and Permissive List: Panel UP-1
- Alarm listAlarm List: Panel UP-1
- FATFactory Acceptance Test Record: Panel UP-1
- O&M manualOperation and Maintenance Manual: Panel UP-1 (Operation section)
Read inside the course and download as a workbook. The project is optional practice, marked when you submit it; the certificate needs only the modules and the final assessment.

A shareable EDWartens certificate
Finish every module and pass the final assessment, and the optional EDWartens certificate is yours. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up. See it below.
The course itself stays free whether or not you ever buy one.
Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.
Pairs well with
PLC programming 路 FreeSiemens TIA PortalFrom zero electrical knowledge to a working, simulated S7-1200 program, for nothing.
PLC programming 路 FreeSiemens TIA Portal in Three HoursThe first three hours of the Siemens TIA Portal course, cut to end on a win: what a PLC is, how it is wired, a project configured in TIA Portal, and your first ladder program running in simulation. Finish it in an evening or two, earn a certificate, and carry straight on into the full course.
PLC programming 路 FreeTIA Portal: Build a MachineOne machine, start to finish. Take a bottle filling line from a written specification and an I/O list to a structured S7-1200 program with a fill station, a capper, a reject sorter and an operator screen with alarms, then test it against a written record and archive it for hand-over. The lessons are the reference; the machine is yours, and it is what you submit.

Common questions
Is easySoft free?
Yes to download and simulate; a licence is needed only to download to a physical easyE4.
easyE4 or Siemens LOGO!?
Both are control relays for small tasks; easyE4 adds SmartWire-DT, more expansion and cloud connectivity. The free LOGO! course covers the other one.
Are all lessons official?
Yes, all from Eaton's English channel.
Is the Eaton easyE4 Control Relay with easySoft 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 an Eaton qualification?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not an Eaton credential and is never described as one.
Who made the video lessons in the Eaton easyE4 Control Relay with easySoft course?
