The VPLC lab

A virtual controller wired to a process. Run the reference program to see it pass, then write your own, in ladder or in Structured Text, and download it here. Watch variables, modify them and force I/O as you would online with a real controller. Everything runs in this page.

A teaching and testing simulator. It is not a safety system and it does not replace commissioning on real hardware. Results are behavioural: timings and edge cases on a particular vendor's controller can differ.
