ClassicLadder is described as 'An open source project to have a free ladder and sequential (grafcet) programming software coded in C language (to be used for educational as PLC Simulator, training, in Software PLC on PC computers or embedded platforms, ...)' and is an app. There are seven alternatives to ClassicLadder for Windows, Linux, Mac, Web-based and SaaS. The best ClassicLadder alternative is CODESYS. It's not free, so if you're looking for a free alternative, you could try CODESYS or 4diac. Other great apps like ClassicLadder are LOGO! Soft Comfort, Automgen, Outseal and Studomate.
CODESYS is the leading manufacturer-independent IEC 61131-3 automation software for engineering control systems. It is used to program many hundreds of different controllers, PLCs, PACs and other automation system, even via an Industry 4.0 interface.
