WebSPS – Online PLC Simulator
WebSPS is an intentionally simple simulation tool for PLCs. Most industrial-grade simulators are expensive and packed with features for simulating entire device setups. For those just starting out—whether for university or personal interest—these tools are often overkill. I launched this project to make getting started with PLC programming easier for everyone. All you need is a web browser.
