Ladder Diagram Program
The Ladder Diagram program consists of the Ladder Diagram representation of the logic and program variables. The program executes Ladder Diagram rungs from top to bottom and from left to right. The program variables consists of local and external data types along with its data types, initial values and size. To understand the link between program structure in the Rockwell IDE and Program structure using Simulink PLC Coder™ refer to
When naming Programs choose different names for the Programs even if they are in different Tasks. Rockwell does not allow Programs to have the same names even if they are in different Tasks. For example, if you have an Input Task and Programs named Program and Program 1 these Program names will be unable for use in other Tasks in the same controller.
