Build your very first PLC program step by step — add instructions, set up the I/O, and see it run, all free in the browser-based ACC PLC Simulator.

⚡ QUICK ANSWER
Building your first PLC program comes down to a few steps: set up your I/O so the program knows which addresses are inputs and outputs, add your instructions on a rung — a contact for the input and a coil for the output — then run it and watch the logic execute. A simple starting program is one input turning on one output, which teaches the core pattern every ladder program builds on. You don't need any hardware to start: the free browser-based ACC PLC Simulator lets you add instructions, configure I/O, and see the program run right in your browser. Once the basic input-to-output rung makes sense, everything else — timers, counters, math — is built on the same foundation. The full walkthrough is in the guide below.
