instructions supported in ladder diagram
the supported ladder diagram instructions are useful while importing the ladder into simulink. the instructions can be categorised 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
