Project
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 16 hours
OEE for five moulding machines: Node-RED on a Raspberry Pi as the edge gateway, Modbus TCP to MQTT to InfluxDB
Design, build, validate and document an edge gateway that counts shots and cycle time on five injection-moulding machines over Modbus TCP, publishes them as MQTT, stores them in InfluxDB and shows OEE per machine per shift on a Node-RED dashboard. You deliver the flows, your own tag and topic register, your own validation report against manual counts, and the backup and deploy procedure. The sample pack shows what an integrator hands over for a data project.
Sample document pack, 8 documents, filled in for the scenario
- URSUser Requirements: Machine Data and OEE, Moulding Shop
- SDSSoftware Design Specification: Edge Gateway EDGE-01
- RegisterTag and Topic Register: Machines IMM-01 to IMM-05
- IP planIP Plan and Device List: Moulding Shop VLAN 20

FAQ
Common questions
Is Node-RED a PLC replacement?
No. It moves data, builds dashboards and integrates systems; the PLC keeps control. The course is explicit about that boundary.
Do I need hardware?
No. Node-RED on your PC with simulated devices covers every module; a Raspberry Pi and a USB-RS485 adapter make the Modbus modules real.
Do I need to code?
A little JavaScript in function nodes, taught as you go.
Is the Node-RED for Industrial IoT 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 vendor qualification?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a vendor credential and is never described as one.
Who made the video lessons in the Node-RED for Industrial IoT 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 Node-RED for Industrial IoT course take?
Plan on about 26 hours in all, including the video lessons, notes and practice tasks. It is self-paced, so you work through the thirteen modules at your own speed.
Is the Node-RED for Industrial IoT 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 IIoT training in India as well?
Not as a separate course. EDWartens India runs the Automation Engineer Program (AEP), a classroom programme at its Electronic City centre in Bangalore. The Automation Engineer Program (AEP) covers PLC, SCADA, HMI, drives, measuring instruments, PID basics and control panel design, 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/automation-training-bangalore, and the programme itself at edwartens.co.in/courses/aep.
