Best PLC Programming Courses Online (2026): 10 Compared

The best PLC course is the one that matches the controller used in your target job and makes you execute, diagnose, modify, and explain working logic. For official platform training, shortlist Rockwell Training Services for Logix or Siemens SITRAIN for SIMATIC. For a broad self-paced catalog, compare RealPars and SolisPLC against the exact skills you need. Use the verified free PLC course list when budget is zero.

This page owns the online PLC course/provider comparison intent. The PLC training-program comparison is for employers, colleges, apprenticeships, multi-week programs and team procurement. That separation prevents a video subscription from being compared as though it were equivalent to a supervised lab program.

Provider scope and access were reviewed from official pages on 26 July 2026. Prices, regional catalogs, prerequisites, software entitlements and certificate rules change, so the live provider page controls. We do not claim measured employment outcomes or award a numerical “best” score without a published learner-outcome dataset.

How to choose a course

Three questions narrow the field:

Vendor focus: Allen-Bradley, Siemens, Mitsubishi, multi-vendor? Most North American jobs want AB; most European jobs want Siemens.
Evidence vs price: record the complete current cost, software/runtime entitlement, lab access, support window and assessment evidence. Price alone says nothing about transfer to the job.
Format: distinguish video, executable simulation, remote hardware, owned hardware, live instruction and individually assessed work. They solve different parts of the skill.

Before comparing providers, use the PLC training guide to see the curriculum, practice loop, hardware boundaries, and evidence a useful programme should cover.

Evidence, access and limitations

Catalog availability: The source registry and seeder define 140 scenario records marked published, plus the separate sandbox definition. The number visible to a visitor can be lower because access depends on account state, tier, entitlement and staged feature rollout. The no-account /try experience is a guided first program; catalog scenarios use an account.

This is a learning and prototyping simulator, not a production PLC or a substitute for testing on the target controller and hardware.
Vendor dialect support teaches transferable syntax and logic patterns; it does not emulate every instruction or firmware behavior of each vendor runtime.

Ownership disclosure: PLC Programming IO and PLC Simulation Software are operated by the same publisher. This is an editorial and commercial product placement.

Practice companion: PLC Simulation Software

PLC Simulation Software is the hands-on browser practice layer we recommend when an online course is mostly video, text, or quizzes. The simulator combines lessons, editable logic, simulated I/O, and scenario feedback. Its versioned product facts document the current free-account policy, lesson allowance, maintained dialect list, scenario-access caveat, and limitations.

Best for: repeating ladder-logic exercises, comparing supported syntax patterns, and producing test evidence while following a third-party or manufacturer course. Not for: earning a Rockwell, Siemens, Mitsubishi, Omron, Schneider, or other third-party credential. It is a learning and prototyping simulator, not a production PLC, hardware engineering IDE, or exact firmware emulator. Ownership disclosure: plcprogramming.io and PLC Simulation Software are operated by the same publisher; that relationship is why the claims above link to a machine-readable facts source.

1. RealPars industrial automation courses

RealPars publishes a membership catalog organized by courses and skill paths, including PLC programming and adjacent automation topics. Its current page says certificates are issued for completed courses and that selected partner courses can carry a partner-company certificate.

Best fit: learners who want a broad, structured automation catalog. Verify: the precise PLC family/version, exercises, feedback path, certificate issuer, included membership tier, cancellation rules and what is explanation versus executable practice.

2. SolisPLC

SolisPLC publishes online automation courses with Allen-Bradley and Siemens material plus adjacent HMI, vision, networking and controls topics.

Best fit: learners seeking specialist, project-oriented training. Verify: exact course access, support, projects, software/hardware prerequisites, subscription or one-time terms and whether submitted work receives individual feedback.

3. Rockwell Automation Training Services

Rockwell Automation Training Services organizes learning by technology track and job category, including PLC hardware/software programming, instructor-led courses, Learning+ subscriptions and certificate programs.

Best fit: teams or individuals working on an identified Allen-Bradley platform who need manufacturer training. Verify: course number, prerequisite path, controller/software version, e-learning versus instructor-led format, lab access, region, registration policy and the difference between course completion and a certificate program.

4. Siemens SITRAIN

Siemens SITRAIN offers learning events, virtual or physical classrooms, self-paced access and blended learning journeys. Siemens' current SITRAIN access page also describes virtual exercise labs for practical work in many courses.

Best fit: learners targeting SIMATIC/TIA Portal with a manufacturer-defined path. Verify: region, course or journey, TIA release, virtual-lab inclusion, live consultant access, membership period and certificate/assessment terms.

5. A current PLC course on a marketplace

Marketplaces such as Udemy can be useful for a narrow topic, but the platform is not the instructor. Evaluate the exact listing: named instructor, update date, software version, preview, curriculum, Q&A activity, downloadable files and recent reviews that discuss the current course.

Best fit: a bounded skill gap where you can inspect the course before purchase. Verify: live price and refund terms, because marketplace pricing and promotions vary.

Specialist and practice paths

6. Siemens SCE learning modules

Siemens SCE provides learning documents and modules for educational use. It is a strong theory-and-exercise source for SIMATIC learners, but software, access rights, hardware and certificates are separate questions. See the source-checked details in the free PLC course owner.

7. Mitsubishi Electric FA e-learning

Mitsubishi Electric publishes browser and selected offline e-learning around MELSEC, GX Works and automation topics. Use it when the target plant or role uses Mitsubishi, then separately verify the engineering-software and hardware path.

8. CODESYS learning and Development System path

CODESYS is useful for IEC 61131-3 practice and multi-language concepts. Separate the free Development System from runtime licences and demo limitations, and do not treat CODESYS behavior as proof for a different vendor controller.

Free and complementary paths

9. Schneider Electric University and other official vendor learning

Official vendor learning is strongest when it matches the target product family. The free owner records verified access boundaries for Schneider Electric University, Siemens, Mitsubishi, CODESYS, Inductive University, OpenPLC and other sources without assuming the IDE or certificate is included.

10. PLC Simulation Software as a practice companion

PLC Simulation Software combines browser lessons, editable logic and simulated I/O. It is useful for repeatable practice alongside another course, not for manufacturer certification or exact controller-firmware emulation. Ownership disclosure: it shares ownership with this site; current claims are linked to its versioned product facts.

Other sources worth checking

a local technical college with supervised, individually assessed hardware labs;
an OEM or integrator academy built around the equipment you maintain;
employer-delivered training with access to plant standards and an isolated test rig;
official manuals, sample projects and application notes paired with a reproducible project.

Recommended path for a complete beginner

If you are starting from zero, advance by evidence rather than a promised calendar:

Learn scan, I/O, Boolean logic, timers, counters, interlocks, analog scaling and safe test boundaries.
Pick the vendor visible in real target-job postings and learn its project, addressing/tag, download, online and diagnostic workflow.
Complete at least four acceptance-tested projects with normal, timeout, contradictory-input, restart and communications-loss cases.
Repeat one project on an isolated physical or remotely supervised rig and reconcile the wiring, program and HMI evidence.
Build a portfolio that states versions, assumptions, test cases, results and limitations.

No course can guarantee a job or a fixed completion time. The useful output is reproducible skill evidence aligned to the target role.
