Virtual PLC Lab
A PLC trainer no institute has to buy. Students build real ladder logic in the browser and watch a simulated machine respond.
Syllabus
| Module | Covers |
|---|---|
| Days 1–2 · What a PLC Is | Hardware, the scan cycle, inputs and outputs, I/O addressing |
| Days 3–4 · Logic | AND and OR, NO and NC contacts, coils, reading a rung |
| Day 5 · Latching | Start/stop, self-holding circuits, emergency stop |
| Days 6–7 · Timers & Counters | TON, TOF, TP, CTU, CTD, rising and falling edges |
| Day 8 · Sequence Control | States, transitions, and a bottle-filling machine |
| Days 9–10 · Sensors & Actuators | Object sensors, proximity, limit switches, motors, valves |
| Days 11–12 · Machines | Conveyor lines and a full automatic object-handling machine |
What your students will be able to do
- Read a ladder rung and predict what it will do
- Explain the PLC scan cycle and why inputs are snapshotted
- Wire digital inputs and outputs to I and Q addresses
- Build AND and OR logic with series and parallel contacts
- Use NO and NC contacts to make a safe start/stop circuit
- Build a self-holding motor circuit with an emergency stop
- Apply TON, TOF and TP timers to the right problem
- Count events with CTU and CTD, including edge detection
- Run a machine as a state sequence
- Drive motors and read sensors on a conveyor line
Final test and certificate
Students who sit the Virtual PLC Lab final and score 50% or more receive a completion certificate from BrainBit Infotech Private Limited, carrying a number anyone can check on our certificate verification page.
Questions teachers ask
Do we need real PLC hardware?
No. The whole lab runs in a browser, including the scan engine and the machine simulation. It works with no internet once the page has loaded.
Is this a simulator or just slides?
A simulator. Students drag contacts and coils onto rungs, press RUN, and watch a virtual conveyor and sensors respond in real time.
Does it match a polytechnic syllabus?
It follows the usual first-year sequence: hardware and I/O, logic, latching, timers, counters, sequence control, then sensors and machines.
