1. A method, comprising:

  • receiving Sequential Function Chart (SFC) logic comprising Steps and Transition on a physical computing device;

    converting the Steps and Transitions of the Sequential Function Chart logic to function block logic on the physical computing device; and

    uploading the function block logic from the physical computing device to a controller, wherein converting the Steps and Transitions of the SFC logic comprises converting the Steps and Transitions of the Sequential Function Chart logic to the function block logic using a block library stored on both the physical computing device and in the controller, the block library comprising a plurality of specific function blocks implementing SFC functionality that provide executable code to convert Steps and Transitions of the SFC logic to the function block logic; and

    executing the function block logic in the controller by using the block library stored in the controller.
