An industrial automation course syllabus covers electrical basics, sensors and instrumentation, PLC programming, HMI and SCADA, drives and motors, PID control and industrial networks, ending in a project. The careers it leads to include PLC programmer, SCADA engineer, commissioning engineer and instrumentation technician. This post lists the modules, the jobs and a free way to study each part.
What is industrial automation?
Industrial automation means using control systems to run machines and processes with little manual work. A packaging line, a water treatment plant, a lift and a bottling plant all rely on sensors that measure, controllers that decide and actuators that act. A course in the subject teaches you to design, program, install and keep those systems running.
What does the syllabus include?
Names differ between colleges and providers, but the content settles into nine blocks. Use this list to read any syllabus.
- Electrical fundamentals. Voltage, current, power, three-phase supply, relays, contactors and motor starters. Start with the electrical fundamentals for technicians course if this is new.
- Sensors and instrumentation. Pressure, temperature, level, flow, 4 to 20 mA signals and calibration. See the industrial instrumentation course.
- PLC programming. Ladder logic, timers, counters, analog scaling, structured text. The Siemens TIA Portal course is a good beginner route.
- HMI design. Screens, alarms and navigation, covered in the HMI design course.
- SCADA. Tags, device connections, alarms and history, as in the Ignition SCADA course.
- Drives and motion. Variable frequency drives, soft starters and servos. The VFD course is the entry point.
- Process control. On-off and PID control, tuning and loop behaviour, in the PID control course.
- Industrial networks. Profinet, Modbus, EtherNet/IP and OPC UA, in the industrial communication course.
- Projects and practice. Panel drawings, commissioning, fault finding and a capstone.
Modern syllabi also add two newer topics. One is industrial cybersecurity, since controllers now sit on networks. The other is data and AI, such as logging machine data and using models to spot faults. The AI for industrial automation course is an example, and the OT and ICS cybersecurity course covers the security side.
How is the syllabus usually paced?
Here is a worked example of a self-paced year. It is a suggestion, not a standard. At 5 hours a week:
| Months | Focus | Approx. hours |
|---|---|---|
| 1 to 2 | Electrical basics and sensors | 40 |
| 3 to 4 | PLC programming | 40 |
| 5 | HMI | 20 |
| 6 | SCADA | 20 |
| 7 | Drives and PID | 20 |
| 8 | Networks | 20 |
| 9 to 12 | Project, security and review | 60 |
That adds to 220 hours. Faster learners compress it, and busy learners stretch it. If you are studying a degree or diploma, the weights differ, and the course might come with lab time on real hardware. The self-paced table is simply a map of the order that works.
Two public places help when you build your own syllabus. NPTEL lists over 3,200 courses for self-study (page opened 17 October 2026), and some are on control and automation, so check each course page for its current status and any exam arrangements. ISA publishes standards and training for automation professionals. Treat both as additions to hands-on practice, not replacements for it.
What careers does the syllabus lead to?
Each role uses a different slice of the nine blocks. A PLC programmer or controls engineer leans on PLC, networks and process control. A SCADA engineer uses SCADA, HMI and networks. A commissioning engineer needs wiring knowledge, PLC fault finding and a calm head on site, as in our guide to becoming a commissioning engineer. A technician calibrates instruments and keeps loops healthy. A maintenance engineer troubleshoots under pressure, and a panel designer turns a specification into drawings.
What you will be paid, and how many jobs exist, depends on your country, sector and employer. We avoid quoting a salary here because a single number would mislead. Use named public sources for your own country and date them. Our posts on PLC programmer salary by country and automation jobs by country show how to search, and the controls engineer career route lists the steps. No course can promise a job. What employers ask for is evidence: a project, a clear explanation, a certificate they can check.
How do you study the syllabus for free?
Use the free hubs. The free PLC courses hub, the SCADA hub, the instrumentation hub and the drives hub list the courses block by block. The PLC foundations path is a ready order for beginners. Practise in simulators: the free lab guides to a PLC simulator and a ladder logic simulator need no hardware.
For a 12-week plan built from free courses, read a free industrial automation course with certificate: a 12-week curriculum. For where each course fits, see free learning paths to a controls, automation or industrial AI role.
Where does an internship fit?
A syllabus gives you knowledge. A project gives you proof. EDWartens offers free engineering internships in tracks such as PLC, SCADA and HMI, instrumentation, commissioning and control panel. All are free to join, with no application or interview, any start date and a length from one week to 24 months. They are training, not employment, and no stipend is paid. The certificate and other documents are optional paid add-ons, shown in your currency before you pay and verifiable at /verification. Whether a university gives credit is its own decision. Start from the engineering internships page.
Course, diploma or degree: which route?
The syllabus is similar across routes, but the depth, the time and the proof differ. A short online course teaches one block, such as PLC or SCADA, in weeks. A diploma or certificate programme joins several blocks and usually adds lab time. A degree in electrical, electronics, instrumentation or mechatronics engineering gives theory such as control systems, circuits and signal processing, and its automation modules sit on top of that base. Fees and entry rules vary by provider and country, so check each one directly.
For a working technician or a student in a related branch, the practical choice is often a degree or diploma for the base, plus free courses and projects for the tool skills that employers list in job advertisements. For a career changer, a sequence of focused courses with a project at each step is usually faster to start. Neither route removes the need to practise. Employers read the same thing in both: what can you build, test and explain?
Which skills sit outside the syllabus?
Four skills rarely appear in a module list but decide how quickly a new engineer is trusted. Reading drawings is the first: electrical schematics, P&IDs and I/O lists. Documentation is the second, because a program that nobody can follow is a liability. Communication is the third, since a controls engineer talks to operators, electricians and managers in the same day. Safety awareness is the fourth: lock-out and tag-out, safe isolation and respect for energy. Our guides on safe isolation and the factory acceptance test checklist are a practical start, and the control panel wiring simulator lets you practise drawings and wiring on screen.
How to choose your first block
If you are new, start with electrical basics and a PLC. If you are an electrical or electronics student, begin with the PLC and sensors, since you already have the circuits. If you are a mechanical student, add electrical fundamentals first. Whatever your start, finish a project in each block before moving on. A syllabus is a list of things to learn, but a portfolio is the list of things you have done, and that is the list a hiring manager reads.
