PLC Visual Learning Studio
Industrial Control Automation
$12.99 · Designed for iPad. Not verified for macOS.
New: 19-image visual gallery with full-screen diagrams, interactive sandbox simulations, and P&ID schematics for all 5 IEC 61131-3 languages.
The complete PLC learning environment — built for engineers, technicians, and students.
PLC Engineering Lab is a structured, hands-on reference app covering Programmable Logic Controllers from first principles through advanced industrial applications. Whether you're studying for a certification, transitioning into automation, or need a fast reference on the job, this app has you covered.
LEARN — Structured Curriculum
Six courses, multiple modules, and step-by-step lessons covering every major PLC topic: system architecture, hardware, I/O wiring, all five IEC 61131-3 programming languages (Ladder Logic, Structured Text, Function Block, Sequential Function Chart, and Instruction List), PID control, industrial networking, SCADA, safety systems, and Industry 4.0.
• Progress tracking with completion badges
• Bookmarks to save your place
• Built-in quizzes to test your knowledge
• Estimated read times per lesson
CODE SANDBOX — Live Editor + Simulation
Write and simulate PLC code directly on your device using a full CodeMirror syntax-highlighted editor. Switch between Ladder Logic, Structured Text, Function Block, and Sequential Function Chart with one tap.
• Live simulation panel shows real I/O logic in action
• Motor Start/Stop latch with toggle inputs and LED outputs
• Traffic light state machine with variable watch
• SR flip-flop simulation for Function Block
• Step-by-step SFC machine sequencer
• Load built-in examples or write your own
PROJECTS — Interactive Diagrams
