Question 1

Can I draw ladder diagrams with this tool?

Accepted Answer

Yes. The Industrial symbol pack (114 symbols) includes contactors, overload relays, control relays, push buttons, limit switches, timers, and motor starters — everything needed to draw ladder-style control diagrams. Pre-built templates cover DOL and star-delta starters and three-wire start-stop seal-in circuits.

Question 2

Does it simulate ladder logic like a PLC?

Accepted Answer

It simulates the electrical circuit behind the ladder diagram — the built-in SPICE engine solves the actual voltages and currents in your control circuit. For rung-by-rung PLC ladder-logic execution with virtual I/O, our companion tool at plcsimulationsoftware.com runs ladder programs with virtual I/O in the browser.

Question 3

Is the ladder diagram tool free?

Accepted Answer

Yes. You can draw and export ladder-style control diagrams free on the starter plan with no signup to begin. Paid plans unlock unlimited diagrams, the full Industrial symbol pack, and complete SPICE simulation.

Question 4

What ladder diagram examples are included?

Accepted Answer

The template library and diagram library include DOL motor starters, star-delta starters, reverse-forward starters, start-stop seal-in circuits, and dozens of published ladder-logic reference diagrams you can open, edit, and export.

Question 5

Can I export ladder diagrams for documentation?

Accepted Answer

Yes. Export as high-resolution PNG, scalable SVG, or print-ready PDF with multi-page title-block support, plus a Bill of Materials CSV listing every contactor, relay, and device in the drawing.
