  1. The box won't move. Where would you look first?
  2. Compare the sensor signal with the ladder logic.
  3. Adjust the virtual sensor. Stopped does not mean safe.
  4. Should it run or stop?
  5. Now test your fix. Watch the conveyor and logic respond together. Finish every check in the free trial.

This is an excerpt from the real simulation, recorded with a local test account. It does not show a completed assessment. Full verification continues in the trial. Practice maintenance is not real LOTO.

Put an explanation into practice while it is still fresh. PLCTrain provides online PLC training through browser-based conveyor investigations, with optional coaching and account-saved progress. Inspect simulated inputs and ladder logic yourself, try a repair, and return to the investigation when you are ready.

  • Three conveyor fault investigations
  • Live PLC signals and moving sensors
  • Optional coaching and saved progress

Could they follow the evidence? Did they need help? Did they prove the repair? Those are the questions that make a practice session useful for coaching.

The next useful conversation

Can you trace the input without a hint?

Ask the learner to explain which physical sensor drives the PLC tag, then repeat an input-mapping exercise with a different fault. A correct repair with help is a starting point for coaching, not proof of independent skill.

What is PLCTrain?

What does the online training experience involve?

Start with the public troubleshooting guides or the gameplay recording to see the training approach. Create an account, confirm your email in the same browser, and sign in to open Conveyor Rescue. The training connects PLC terms to a visible machine: a photoeye changes, an input reports a state, and a ladder condition affects the belt. Explanations are available when needed. The demo is a bounded sample of practical troubleshooting, not a promise of a complete online PLC programming curriculum.

"The box will not feed."

Your callout
Operator report
"There is a box waiting on belt 1. The section ahead looks empty, but it will not move on. Can you take a look?"

Where would you look first?

The space ahead. The photoeye. The PLC input and rung. The motor output.

Choose your own starting point. Compare the machine with the signals, try a likely cause, and test what changed. A wrong lead is recoverable.

Moving once is not enough. Prove that the line feeds when clear and stops when the receiving station is full.

One complete investigation. Coach off until you ask.Training simulation only
01 / 03

Build an online practice session around one question.

  1. Read a focused explanation.

    Choose a guide about a confusing signal or ladder instruction. Predict what should happen on the conveyor before opening the investigation, rather than trying to memorize every PLC term at once.

  2. Try the decision yourself.

    Use the operator report to choose a check. Compare the machine and program, request coaching if needed, and make a correction supported by what you observed.

  3. Return to what needs practice.

    Your progress is saved to your account. Review an uncertain decision and repeat the check when you return. A later attempt gives you another opportunity to explain the signal path.

Future technicians & students

See what troubleshooting involves. Connect unfamiliar PLC terms to a machine you can watch and control.

Working maintenance technicians

Practice checking the evidence before changing parts or code. Repeat a fault and see how your decisions affect the line.

Maintenance managers & trainers

Try the demo yourself and decide whether this approach fits your team. Use a scenario to talk through what a technician would check and why.

Available in the free demo: conveyor troubleshooting, photoeye alignment, input mapping, and basic ladder logic.

Our focus: realistic decisions, visible signals, proof of repair and repeat practice. The next lessons will be tested with technicians before we expand the library.

After trying a repair, you can optionally share your experience and interests to help shape the next lessons.

Is this a complete online PLC course?

The free Conveyor Rescue demo is a sample of the training approach. It covers conveyor troubleshooting, photoeye alignment, input mapping, and basic ladder logic; it is not a complete vendor programming course or an accredited qualification.

Do I need to attend a scheduled class?

No scheduled class is required for the browser demo. You choose when to investigate and when to ask for the optional coaching included in the simulation.

Can I pause online training and return later?

Yes. Demo progress is saved to your account. Sign in with the same account when you return to continue your practice.

Do I need PLC experience before starting?

No prior ladder logic experience is required to begin. The visible conveyor and optional explanations connect unfamiliar input and program terms to behavior you can observe.

What do I need for online PLC training?

Use a modern browser and internet access. A larger screen makes the conveyor and ladder views easier to compare. No physical PLC, programming license, or training rig is required.

Can I evaluate the training before signing up?

Yes. The free troubleshooting guides and gameplay recording are public. Playing Conveyor Rescue requires a free account, email confirmation, and sign-in; no card is requested.
