PLC simulator for Chromebook: test checklist
Direct answer
The learner can open, run and save a bounded PLC exercise in the browser and identify which later target-tool tasks still require another environment.
Written for students and instructors using managed or personal Chromebooks that cannot install Windows-only PLC engineering suites.

Scenario setup
ChromeOS version, browser, account policy, network, storage, keyboard, screen size, accessibility and target learning task.
I/O and state map
Browser editor and runtime through saved project state, scenario checks and exportable evidence.
Normal run
A start-stop and timer exercise completed, reopened and repeated from reset.
Boundary run
Managed-browser restrictions, blocked storage, offline loss, small screen, unsupported syntax and target transfer.
Injected fault
A browser, account, persistence, runtime, input or compatibility issue.
Target check
The accepted behavior recreated later in the required vendor environment and controller.
