The course project
Optional practice that ends in the kind of job the course prepares you for, with the documents that go with it.
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; façade, 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)

FAQ
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?
The creators named in the Credits block at the foot of this page, on their own YouTube channels. EDWartens did not make the videos and the creators are not affiliated with EDWartens. What EDWartens wrote is the study plan, the notes, the practice tasks and the assessments.
How long does the Eaton easyE4 Control Relay with easySoft course take?
Plan on about 10 hours in all, including the video lessons, notes and practice tasks. It is self-paced, so you work through the eight modules at your own speed.
Is the Eaton easyE4 Control Relay with easySoft course free in India, and what does the certificate cost?
Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹499 including GST for this beginner course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.
Is there classroom PLC training in India as well?
Yes. EDWartens India runs the Automation Engineer Program (AEP), a classroom programme at its Electronic City centre in Bangalore. In the Automation Engineer Program (AEP) you write and test PLC programs on wired PLC panels, taught in person at our Electronic City centre. This free course is separate and fully online; it is a good way to try the subject before deciding on classroom training. Details are at edwartens.co.in/plc-training-bangalore, and the programme itself at edwartens.co.in/courses/aep.
