Ladder diagram is a fantastic programming language for visual programmers like electricians. However, it can have a few limitations. Solutions to these limits are easy to work through with structured text programming. It feels like a higher-level language, allows easy code replication and commenting, and can still integrate well with basic PLC applications. Both are IEC 61131 languages, and have specific strengths for your application. Check out both styles of controllers on our webstore.
