  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.

Practice the checks that support a maintenance decision. PLCTrain provides browser-based PLC maintenance training with simulated conveyor faults. Compare a stopped belt, its photoeye input, and the ladder conditions controlling it. Diagnose the mismatch, explain a correction, and demonstrate both feeding and stopping.

  • 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 can a maintenance team practice here?

A run request, a PLC output command, and actual conveyor motion describe different things. Practice separating them before choosing a repair. In an observed session, a trainer can ask which condition prevents feeding, what evidence supports that explanation, and which test would disprove it. Review the individual practice record to discuss hint use and verification. The sample skills report illustrates a possible coaching conversation; it is not an available live team dashboard, a preventive-maintenance system, or a workplace qualification.

"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

Practice a maintenance investigation through handover.

  1. Describe the operating condition.

    Use the operator's complaint and the visible receiving zone to state the expected behavior. Explain whether a stopped belt is an appropriate response to a full station or evidence of a mismatch.

  2. Separate the request from the response.

    Compare the run request, photoeye state, named input, and ladder condition. Identify what supports the chosen correction instead of treating a replacement component as proof of diagnosis.

  3. Explain the proof of repair.

    Repeat clear and occupied receiving conditions and complete the transfer. In the debrief, describe what changed, what each check demonstrated, and which assumptions still needed coaching.

A shared machine.
A useful maintenance debrief.

Use the three Conveyor Rescue investigations to observe evidence selection and repair verification. The demo concentrates on sensor and PLC signal reasoning. It does not reproduce every drive, electrical, mechanical, or safety-system fault found on a real production line.

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.

Who is this PLC maintenance training for?

It is for maintenance technicians, students entering maintenance, and trainers observing diagnostic decisions. The demo connects a familiar conveyor complaint with sensor evidence and basic PLC logic.

Does this teach preventive maintenance schedules?

No. Conveyor Rescue focuses on diagnosing a modeled conveyor fault and verifying its correction. It does not provide preventive-maintenance schedules, asset management, or equipment-specific service procedures.

What should a trainer observe during practice?

Ask why the learner selected each check, how the physical input relates to the program tag, and whether the final tests demonstrate both feeding and stopping. Discuss any coaching prompts needed along the way.

Are team dashboards or employer reports included?

The demo includes individual practice records. The manager report shown on the page uses illustrative sample data; it is not a live team dashboard or an automatically delivered employer report.

Does completing the demo authorize work on machinery?

No. It records practice in a simulation. Real equipment work still requires the relevant training, authorization, documentation, and site procedures.

How can we try the maintenance training?

Create a free account, confirm the email, and sign in to Conveyor Rescue. A trainer can observe an investigation and discuss the decisions afterward. No physical PLC or card is needed.
