What the simulator does not emulate
A direct account of timing, firmware, safety, project-file, browser and catalog-access boundaries.
Canonical limitations
This is a learning and prototyping simulator, not a production PLC or a substitute for testing on the target controller and hardware.
Vendor dialect support teaches transferable syntax and logic patterns; it does not emulate every instruction or firmware behavior of each vendor runtime.
Scenario and lesson access varies by account state, plan, entitlement and staged feature rollout.
Native vendor project-file export is not guaranteed.
Operational boundaries
Not a production controller
The browser engine is for learning, prototyping and logic reasoning. It does not control plant equipment and must not be inserted into a production control path.
Not vendor firmware emulation
The learning dialects model selected syntax and semantics. They do not reproduce firmware revisions, task scheduling, module behavior, system flags or every instruction.
Teaching time is not wall-clock certification
Timers and scenario physics advance on a deterministic teaching clock. A displayed scan interval is not proof that a physical controller will execute at that period or with that jitter.
Not a safety-validation tool
E-stop, interlock and safety scenarios teach reasoning. They do not calculate PL/SIL, validate a safety function, replace a risk assessment or certify machinery.
No guaranteed native project export
Logic learned here must be recreated and verified in the target vendor environment. Native project-file export is not promised.
Availability varies
The source registry and seeder define 140 scenario records marked published, plus the separate sandbox definition. The number visible to a visitor can be lower because access depends on account state, tier, entitlement and staged feature rollout. The no-account /try experience is a guided first program; catalog scenarios use an account.
Browser and device constraints
A current desktop browser is the best editing surface. Smaller touch devices can open learning pages, but complex ladder, HMI, wiring and 3D workspaces may be more practical on a larger screen.
Do not paste production secrets
Use synthetic tags and training examples. Do not enter real plant credentials, proprietary programs, personal data or safety-critical production logic into a learning account.
