Runnable simulator field guide
Try the PLC simulator: test checklist
Direct answer
The visitor can predict, run and explain the first input-to-output behavior, then select the next appropriate practice surface.
Written for first-time visitors who want to run a real PLC exercise before creating an account or choosing a course.
Scenario setup
Device and browser readiness, exercise objective, starting state, input action, expected output, stop behavior and next-step intent.
I/O and state map
First user action through editable PLC logic and scan execution to visible I/O and machine response.
Normal run
The starter program run, changed once and repeated from reset with the result explained.
Boundary run
Blocked script, unsupported browser, hidden input, accidental edit, stale state, lost focus and assumption that animation proves hardware.
Injected fault
A browser, interaction, program, runtime, input, output, machine or expectation mismatch.
Target check
The working behavior saved or recreated in lessons, scenarios and the required target environment.
