PLC virtual lab

A Full PLC Virtual Lab in the Browser — A Station for Every Student, No Rig to Buy

Stand up a virtual PLC lab for a whole cohort in a day. Every student gets their own simulated PLC station — ladder editor, running controller, simulated I/O, plus an HMI builder and a robot cell — in any browser, on any device, including Chromebooks. No hardware rig to buy or maintain, no per-machine install, no admin rights. Every submission is auto-graded, and one instructor can see the whole class at a glance.

What a scalable PLC lab looks like

Give every learner a working station—and every instructor evidence.

The browser lab joins programming, simulated equipment, wiring diagnosis, multi-domain curriculum and objective attempt history so remote practice can prepare students for scarce physical bench time.

Why a virtual lab

The one-rig-per-student lab was never going to scale

A station for every student, instantly

A physical PLC trainer rig serves one student at a time, so a class shares a handful of benches on a rotation. A virtual lab gives all 30 students a full station at once — nobody waits, nobody is idle, and practice continues at home.

Nothing to buy, wire or maintain

A single trainer rig runs into the thousands; a full lab into the tens of thousands, before maintenance contracts and the panels that age out. A virtual lab is software — no capital request, no firmware that falls behind what graduates meet in the field.

No install, no admin rights, any device

It runs in a browser tab on Chromebooks, locked-down lab PCs, Macs, Linux and students’ own laptops. IT installs nothing per machine and distributes no license keys — the roll-out that usually stalls a program simply disappears.

Auto-graded, with live cohort progress

Every submission is marked against test cases the instant a student hits Run, and an admin console shows who is behind before an assessment. The virtual lab does the marking the physical bench never could.

The definition

What is a PLC virtual lab simulator?

A PLC virtual lab simulator is browser-based software that gives every student a complete simulated PLC workstation — ladder editor, running controller, simulated I/O and machine — instead of sharing one physical trainer rig. Each seat costs $199 per year, so a 30-student class runs about $5,970 — less than one mid-range hardware bench.

The cost-per-student arithmetic is the whole argument. A hardware trainer rig serves one student at a time, and the published rig prices in the comparison table below run $10,000–$50,000 before maintenance. A virtual lab simulator prices per student instead: every learner gets a full station simultaneously — in the lab, in the library, and at home — and seats are reassignable when someone withdraws. Budgeting a lab? See the PLC training equipment buying guide for the full hardware-vs-virtual procurement comparison, or the PLC trainer kit alternative page if you are pricing per-bench kits for a class.

What it replaces

Virtual PLC lab vs a hardware trainer rig vs desktop PLC software

The figures below are typical/published prices from the vendors’ own materials, not invented numbers. The point is not that hardware is bad — you should keep a bench for wiring — but that only a browser-based virtual lab deploys to a whole cohort in a day, on the devices students already own.

Every concept below is something a learner builds, runs and is auto-graded on in the browser — the same IEC 61131-3 logic model and the same HMI workflows they will meet on a real plant floor, with no rig and no install.

Students export portfolio PDFs of timestamped, name-attributed completions — verifiable evidence that supports your accredited assessment.

Deploy in a day

Set up a team, invite a cohort, assign a path — a full class can be writing graded ladder logic the same afternoon, no procurement cycle.

Pricing & rollout

Start a virtual lab free — scale with reassignable per-seat licensing

Trial the full virtual lab free and run a small pilot before involving procurement. When you roll out a managed cohort, Pro seats are $199/seat/year on annual billing, reassignable when a student leaves. Managed Teams access has a five-seat minimum; bulk and academic pricing is available on request. See full pricing →

Questions

PLC virtual lab — FAQ

A PLC virtual lab is a software environment that gives every student their own simulated PLC station — a ladder logic editor, a running PLC, simulated I/O and field devices, and (in this platform) an HMI builder and a robot cell — entirely in the browser. Instead of one hardware trainer rig shared by a class on a rotation, each learner writes, downloads and runs programs against a simulated process on their own device, and the lab auto-grades every submission. It replaces the part of a physical lab that never scaled — one rig per student, booked bench time, install and license overhead — while you keep a smaller hardware bench for the wiring and commissioning that genuinely needs metal.
