PLC Simulation Software Overview

Key Strengths

  • Zero install, zero cost, zero licence keys — fastest path to running ladder logic
  • Cross-platform: works on macOS, Linux, ChromeOS and tablets where most PLC software won't run
  • Browser-based saves and shares — perfect for classrooms and self-paced courses
  • Multi-brand syntax support helps learners transfer skills between Allen-Bradley, Siemens, Mitsubishi and Schneider

Limitations

  • Browser-based environment — not a substitute for hands-on hardware programming
  • Cannot connect to physical PLCs or industrial networks
  • Limited to ladder logic, FBD, and ST — no SFC yet

Best For

Absolute beginners learning PLC programmingSelf-learners on macOS, Linux, ChromeOS or tabletsTechnical school and vocational classrooms

Siemens PLCSIM Overview

Key Strengths

  • Industry-standard Siemens emulator
  • Real firmware behaviour, not approximation
  • Tight TIA Portal integration
  • Trusted for production code validation and FAT

Limitations

  • Windows-only
  • Requires TIA Portal — large install (~6 GB+)
  • TIA Portal licence costs €1,200-2,000+/year for production use
