Two PLC Programming Giants
Siemens TIA Portal is the market leader for Siemens PLCs. CODESYS is the universal platform supporting 500+ manufacturers. Both follow IEC 61131-3 standard. Understanding the differences helps you make the right career decision.
Siemens TIA Portal
The gold standard for Siemens S7-1200 and S7-1500 programming. Market leader in India with massive installed base. Expensive licence required. Only works with Siemens hardware. Supports LAD, FBD, ST, SCL. Industry demand is very high — most automation jobs in India require TIA Portal experience.
CODESYS
Universal platform supporting Beckhoff, WAGO, Schneider, ABB, Festo, and 500+ others. Free download with unlimited projects. Supports all five IEC 61131-3 languages. Built-in simulation mode. Strong in European markets and growing in India. 2-hour runtime limit on free version.
Which Should You Learn?
Answer: Both. Learn Siemens TIA Portal for the Indian job market — it is the most demanded PLC software. Learn CODESYS for versatility — it works with any brand and is free to practice. The combination makes you the most employable automation engineer.
How ABC Trainings Teaches Both
The base PLC/SCADA course covers Siemens TIA Portal. The Industry 4.0 add-on introduces CODESYS and OpenPLC for multi-brand experience and free home practice.
Is CODESYS free?
Yes. Free download with unlimited projects. Only limitation is 2-hour runtime on simulation which resets with restart.
Can I get a job with only CODESYS?
In India, Siemens dominates. CODESYS alone is less marketable. Both together is ideal.
