What is the difference between a PLC course and a SCADA course?

A PLC course teaches you to write controller logic: the ladder rungs, function blocks, and timers that make machines move. A SCADA course teaches you the supervisory layer above: the software that reads PLC tags, displays trends, logs data, and raises alarms. In practice, most SCADA engineers need both — you cannot configure a SCADA system well if you do not understand the PLC tag database it reads.

Can I do a PLC SCADA course online for free?

Yes. The free tier of this course includes all structured lessons and the first scenarios — no credit card required. The full 130-scenario library and certificate require a Pro subscription or Cert Pack purchase.

What software do I need for this PLC SCADA course?

Nothing — the entire course runs in your browser. No Studio 5000, no TIA Portal, no Ignition, no Windows requirement. Any modern browser on any operating system works.

How much does a PLC SCADA course cost?

Free to start (no credit card). Pro subscription for the full scenario library. The Cert Pack (certificate + portfolio PDF) is $99 one-time. For comparison, classroom PLC SCADA courses at technical institutes typically range from $800 to $3,000 for a multi-day course. Online courses on Udemy range from $20 to $200 but are video-only without hands-on execution.

What is covered in a PLC SCADA course?

A complete PLC SCADA course covers: (1) PLC fundamentals — scan cycle, I/O addressing, ladder logic; (2) SCADA tag architecture — mapping PLC registers to SCADA tags; (3) HMI development — screen design, widget binding, navigation; (4) Alarm management — ISA-18.2 alarm logic in the PLC layer; (5) Communications — Modbus TCP, OPC-UA concepts; (6) PID control — setpoint management from SCADA; (7) Data historians — tag selection and sampling concepts.

Can I do a PLC SCADA online course free?

Yes. The free tier includes all 18 lessons and the first two scenarios — no credit card required. The full 130-scenario library, interview tracks, and certificate require a Pro subscription ($29/mo) or the Cert Pack ($99 one-time).

How does this compare to a classroom PLC SCADA course?

Classroom courses typically cost $800–$3,000 for a 2–5 day intensive and require travel to a training centre. They have the advantage of hands-on hardware time. This platform costs nothing to start, is available anywhere, and provides more scenario reps than any classroom course — but does not replace hands-on wiring and commissioning experience.

What software do I need for this PLC SCADA course?

Nothing — the entire course runs in your browser. No Studio 5000, no TIA Portal, no Ignition licence, no Windows requirement. Any modern browser on any operating system works.

Is this a full PLC SCADA HMI course?

Yes for the PLC and HMI layers. The HMI Builder teaches widget placement, tag binding, and interlock verification against a live PLC simulation — the same mental model used in FactoryTalk View and WinCC. For SCADA server features (historian, reporting, redundancy), hands-on time in Ignition or WinCC is required.

Q: Does this PLC SCADA course include a certificate?

Yes. The Cert Pack ($99, one-time) includes a downloadable PDF certificate of completion and a portfolio PDF documenting your scenario results. The certificate is not a vendor certification from Rockwell, Siemens, or an ISA affiliate — it is evidence of demonstrated skills for your CV and portfolio.

130 hands-on scenarios covering every layer a SCADA engineer needs at the PLC level: ladder logic, HMI screens, Modbus TCP register maps, alarm logic, and PID control. Certificate of completion included. Free to start.

The discipline

What PLC SCADA programming actually is

A PLC (Programmable Logic Controller) is the controller that makes machines move. A SCADA system (Supervisory Control and Data Acquisition) is the software layer above it — the system that reads PLC tags, shows them on operator screens, logs them to a historian, and sends setpoint commands back down to the PLC. Most job postings that say "PLC SCADA" are asking for someone who can do both: write PLC logic that produces clean, well-named tags, and configure the SCADA system to read them correctly.

The PLC layer is the harder skill to acquire because it requires writing and testing executable code. The SCADA configuration layer is largely a drag-and-drop exercise once you understand the data model. This course prioritises the PLC layer — the part that makes or breaks a SCADA integrator's ability to deliver working systems.

Curriculum

PLC SCADA course curriculum

Six tracks from first principles to SCADA-ready. Estimated hours are for an engineer with no prior PLC experience working at a focused pace.

Track	What you learn	Est. hours	Certificate	Free?
PLC Fundamentals	Scan cycle, I/O addressing, contacts and coils, latching, timers, counters, state machines, debugging	8–16 hrs	Included in Pro + Cert Pack	Free
Core Building Blocks	Function blocks, structured text, analog I/O and scaling, SFCs, shift registers	8–16 hrs	Included in Pro + Cert Pack	Pro
Advanced Topics	PID control, alarm logic, safety systems, Modbus TCP, code organisation, troubleshooting	8–16 hrs	Included in Pro + Cert Pack	Pro
Machine Scenarios (130 total)	Traffic light, motor control, conveyor sort, tank fill, batch mixer, elevator, boiler, PID temp, packaging, wiring labs, VFD, safety, Modbus comms	40–80 hrs	Auto-graded; results in portfolio PDF	Pro
HMI Track	Motor start/stop panel, alarm dashboard, multi-screen navigation, tag binding exercises	6–12 hrs	Included in Cert Pack	Pro
Interview Tracks	Timed scenario challenges: basic ladder, timers and counters, interlocks, sequencers	4–8 hrs	PDF certificate on pass	Pro

Total estimated hours: 74–148 hrs for a complete beginner to SCADA-ready confidence.

Certification

Certificate of completion

The Cert Pack ($99 one-time) generates two documents: a PDF certificate of completion listing the tracks completed and a portfolio PDF showing your scenario results — the scenarios you passed, your solutions, and the grader's test case output.

The certificate is not a Rockwell, Siemens, or ISA certification. It is evidence of demonstrated PLC programming skills — the kind of evidence that carries weight when a hiring manager can see your actual scenario solutions alongside the certificate, not just a completion badge. Many of our users share the portfolio PDF with job applications or link to it from their LinkedIn profile.
