Instructions Supported in Ladder Diagram
The supported ladder diagram instructions are useful while importing the ladder into Simulink. The instructions can be categorized into two:
Instructions that are implemented in Simulink® using ladder diagram blocks with same name
Instructions that are implemented in Simulink using other ladder diagram blocks.
The table lists the instructions that map to blocks in Simulink
