The title promises five PLCs in a day. Realistically? You are not finishing more than 41 hours of training before dinner unless you have discovered a way to pause time.
That slightly ambitious title aside, Learn 5 PLCs in a Day – AB, Siemens, Schneider, Omron & Delta is a remarkably large PLC programming course. It introduces several popular automation platforms rather than locking the entire curriculum to one manufacturer.
I believe it is a very good course for beginners, technicians and maintenance engineers who want to explore multiple PLC brands before deciding which platform to study more deeply.

Five PLC Platforms in One Course
The course covers five different PLC families:
- Allen-Bradley Micro850
- Siemens S7-200
- Schneider Electric M221
- Omron CP1E
- Delta DVP series
At the time of writing, the Udemy listing shows more than 41 hours of video, 278 lectures, over 36,000 students and a rating of 4.6 out of 5. The course was last updated in November 2025.
That is a serious amount of material. This is not one of those courses containing 90 minutes of theory, a certificate and a cheerful goodbye.
What Will You Learn?
The course begins with basic industrial control principles, including switches, relays, motor circuits, latching, interlocking and PLC wiring.
From there, it moves into programming topics such as:
- Ladder logic
- Timers and counters
- Set and reset instructions
- Rising and falling edges
- Data registers
- Comparison and mathematical instructions
- Function blocks
- Analogue inputs and outputs
- Modbus TCP/IP communication
- HMI design
- PLC troubleshooting
The curriculum also includes Factory I/O, Simumatik, Node-RED, Ignition SCADA and other simulation or communication exercises.
That variety is probably the course’s biggest strength. You are not only learning how to energise an output. You also see how PLC logic connects with conveyors, tanks, HMIs, VFDs, SCADA systems and industrial communication.
Practical Exercises Instead of Endless Slides
Several sections use realistic automation tasks.
The Allen-Bradley material, for example, includes a box-sorting project with conveyors, counters, indicators and a pneumatic pusher. Delta exercises cover tank control, analogue signals, palletising, Factory I/O and communication with a VFD through Modbus.
The Schneider section goes into process control, FIFO and LIFO instructions, shift registers, function blocks, Modbus communication and analogue VFD control.
That practical approach helps enormously. A timer instruction looks rather lifeless on its own. Put it into a tank-filling sequence or conveyor system and suddenly the reason for using it becomes obvious.
Do You Need Real PLC Hardware?
The course states that the required PLC software is included, and several exercises use simulation platforms such as Factory I/O, ITS PLC and Simumatik. This allows students to practise many of the lessons without immediately buying five different PLCs—which would be a rather expensive experiment.
Physical hardware is still valuable eventually. Simulators cannot fully recreate wiring mistakes, damaged sensors, loose terminals or the mild panic of downloading to the wrong controller. But they are an excellent starting point.
Who Is This Course Best For?
This course should suit:
- Beginner PLC programmers
- Industrial maintenance technicians
- Electrical and automation students
- Production engineers
- Technicians moving into automation
- Learners comparing different PLC brands
It may also help someone who understands one PLC platform but wants a guided introduction to several others.
Are There Any Downsides?
The course is broad, which means it cannot explore all five PLC ecosystems at an advanced professional level.
Some sections are much longer than others, and the programming environments vary considerably between brands. Moving repeatedly between Delta, Siemens, Allen-Bradley, Schneider and Omron may occasionally feel like changing cars every ten kilometres.
The title is also misleading. This is not genuinely a one-day course. It is a large training bundle that should be studied gradually, with time left for practice.
Final Verdict
Learn 5 PLCs in a Day is a very good multi-brand PLC course for learners who want broad exposure to industrial automation.
Its strongest feature is the sheer range of material: wiring, ladder logic, analogue signals, HMI development, Factory I/O, Modbus, SCADA and troubleshooting across five PLC families.
It will not make anyone an expert in every platform overnight. Nothing will. Still, it offers an affordable way to discover which PLC ecosystem suits you before investing in specialist courses or physical equipment.
