Which PLC software should you learn first?
The honest answer depends on where you want to work. Vendor preference varies strongly by geography and industry:
North American manufacturing jobs
Studio 5000 Logix Designer
Allen-Bradley is dominant in North American automotive, food and beverage, CPG, and oil and gas. The majority of North American job ads list Studio 5000 or RSLogix 5000.
European manufacturing, automation
TIA Portal (Siemens) + CODESYS
Siemens is the dominant platform in German, Italian, and broader European manufacturing. CODESYS covers Beckhoff, Wago, Phoenix Contact, and many others that are common in machine building.
Automotive, Asian manufacturing
GX Works3 (Mitsubishi) or TIA Portal
Mitsubishi is strong in Japanese automotive and Asian contract manufacturing. Siemens is also common in this sector.
Learning from scratch, any OS, no hardware
Browser-based practice + CODESYS
Start with browser-based IEC 61131-3 practice (no install, any OS, free) to build core ladder logic fluency, then download CODESYS (free IDE) for the real vendor software experience.
Start now, no install
Practice ladder logic free in your browser — every vendor's core instruction set
Every vendor's ladder logic — Rockwell, Siemens, Mitsubishi, Omron, CODESYS — implements the same core IEC 61131-3 contact/coil model. Normally open contact, normally closed contact, output coil, timer-on delay, timer-off delay, up counter, down counter. The vendor names for these instructions differ; the logic does not. Build that core fluency here, then transfer it to whichever vendor IDE you need.
