Read what happens in the video
- The box won't move. Where would you look first?
- Compare the sensor signal with the ladder logic.
- Adjust the virtual sensor. Stopped does not mean safe.
- Should it run or stop?
- Now test your fix. Watch the conveyor and logic respond together. Finish every check in the free Conveyor Rescue demo.
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.
Connect the PLC signals to the machine. PLCTrain provides browser-based PLC training for maintenance technicians. Trace simulated photoeye inputs and ladder logic, diagnose a conveyor fault, and verify the repair without physical equipment.
- Free web demo: three guided conveyor faults
- Live PLC signals and moving sensors
- Optional hints and repeatable practice

19 live calls. One troubleshooting method.
The same iPhone and Android experience: a live plant pinned above the tabs and controls. Adjust a sensor and watch the response. Turn the phone sideways for a larger plant view.
Plant networking
Check PLC, HMI, laptop and switch links. Follow ping paths and compare addresses before making a change.
Sensors
Inspect proximity, limit and 4–20 mA behavior, with live plant responses to your adjustments.
Basic electrical
Trace 24 VDC, fuse and contactor-coil paths. Take meter readings before a virtual parts change.
Predict → prove → repair → close. One next action. Fresh proof before closeout. The coach helps you find evidence and refuses to choose the cause. Wrong calls have visible, reversible consequences.
Coming, not included: Conveyor A9–A10 and dedicated PLC-functions, motors/VFDs and safety drills. No public app-store release yet. The browser demos on this page remain separate.
Make the training budget go further
Training shouldn’t end when the trip does.
A week away can introduce new skills. Give technicians a place to keep practicing the decisions they need on the floor—without booking another trip.
One technician. One week away.
- Course tuition
- $5,000
- Travel and stay
- $2,000
- Illustrative total
- $7,000
Before wages, overtime coverage, or time away from the plant. Example budget, not a market average or a quote from a specific provider.
Make troubleshooting practice a routine.
- Practice where you work. Browser demos and the mobile pilot need no travel or physical PLC.
- Make decisions and see the result. Inspect signals, test a repair, and repeat the checks.
- Coach across shifts. Use the same exercise to discuss each technician’s reasoning.
- Budget for the team. Agree access, training scope, and price before enrollment.
The plant responds to your decisions. No countdown or reward for rushing. The goal is an explanation you can support and a repair you can verify.
For maintenance: See what technicians check, where they need a hint, and what to practice next.
For finance: Compare the full team quote with tuition, travel, and coverage costs. Review cost per active learner and evidence of progress.
PLCTrain complements hands-on equipment and vendor training. Learning time still has a cost. This example does not claim $7,000 in savings, superior learning outcomes, or a qualification to work on equipment.

Which check changed your mind?
Ask the technician to explain the evidence behind the change, then try another call without help. A completed simulation is a starting point for coaching, not a qualification.

What is PLCTrain?
A place to practice troubleshooting.
PLCTrain puts the learner in control of the investigation, with explanations available when needed. Observe the simulated conveyor, read its inputs, and follow the conditions controlling a motor output. Conveyor Rescue introduces photoeye alignment, input mapping, and basic ladder logic through three fault investigations, with optional explanations and saved progress.
Inside Line Call / no account needed
"The box will not feed."
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.
01 / 03
Practice the PLC basics behind a conveyor fault.
Predict.
Record the response you expect before changing the plant.
Prove.
Observe the plant, trace a signal or take a reading.
Repair.
Make a virtual change supported by your evidence.
Close.
Pass fresh checks and remove temporary forces. Motion alone does not close a pilot call.
Inside Line Call
The same symptom.
Three different causes.
The public Line Call preview includes: three connected belt zones, each with its own photoeye (a light sensor) and ladder rung (one line of PLC logic). Work through three open investigations and test the complete transfer.

Your first callout is waiting
Try fixing it yourself.
Start Line Call immediately. Inspect the receiving photoeye, trace the input and ladder logic, then prove the repair with optional hints. Existing member training remains available through sign-in.
Try the public Line Call previewFree in your browser. No account or approval needed for Line Call.
Already have an account? Sign inDo I need ladder logic experience?
No. This PLC training demo introduces inputs, outputs, and basic ladder conditions through a visible conveyor. Optional coaching explains the signals as you investigate.
What equipment do I need?
Use a modern browser with internet access. No physical PLC, training rig, or vendor programming software is needed. A larger screen gives the machine and ladder logic more room.
Is this real PLC training?
This is practical PLC training in a simulation: you inspect signals, diagnose a conveyor fault, and verify your correction. The free demo is an introduction to this approach, not a complete vendor programming course or an accredited qualification.
What is in the mobile pilot?
19 live calls: eight Conveyor Rescue investigations, five plant-networking calls, three sensor drills and three electrical drills. The iPhone and Android internal pilot shares the same plant and training behavior. Access is by invitation through training@plctrain.com; there is no public store download yet.
Where do pilot records live?
The mobile pilot has a local roster of up to 10 seats per site, captured names, completed method summaries and CSV export. Settings and records stay on the device. Names are not authenticated identity; cloud sync and signed exports are not included. Browser demos and web-account progress stay separate.
Why do you ask about my background?
After a repair, you can optionally share your experience and interests. Your answers help PLCTrain decide what to build next, and the site owner can see them. You can skip every background question. Creating an account does not sign you up for marketing.
What happens after I sign up?
Confirm your email in the same browser you used to sign up. Your Conveyor Rescue demo unlocks automatically. Other training still needs approval. No payment details are requested.
Does this replace real equipment training?
No. PLCTrain is a simulation, not a qualification or permission to work on live equipment. Follow your site's training and safety procedures for real work.
How does the training-cost example work?
The example adds $5,000 in tuition to $2,000 in travel and stay for one technician: $7,000 before wages or coverage costs. It is an illustrative budget, not a market average or a savings claim. Compare your actual course costs with a PLCTrain team quote and the training scope you need. Simulation complements hands-on and required vendor training.
Which practice needs an account?
The public Line Call repair preview and beginner lessons need no account. Line Call resets on refresh; lesson drafts stay in this browser. The separate free Conveyor Rescue demo includes three guided faults and account-saved progress: create an account, confirm your email, then start. No card or physical PLC is required.
Want guided practice with account-saved progress?
Create a free Conveyor Rescue account for three guided fault scenarios, hints, and video guidance. Your public Line Call session stays separate and does not transfer.
