Do not put step logic directly inside the RUNNING state case. Instead, call the step chain’s Execute() method from the RUNNING state.

While there is a slight learning curve—especially for those accustomed only to ladder logic—the payoff in code reliability, debugging speed, and team collaboration is immense. For any medium-to-large TwinCAT project, especially those involving complex sequences or compliance with standards like PackML or OMAC, implementing the Sistema library is not just a recommendation; it is a . beckhoff sistema library
