Abstract: Embodiments of the present invention include systems and methods for an online load of logic to a triple module redundant (TMR) control system using a cascading switch and designated controller. Application code having SFC logic may be first downloaded to a designated controller of the TMR system. After download to the designated controller, the other controllers of TMR system may be updated in a cascading (circular) pattern. After updating the second controller with the updated logic, the designated controller may provide correct state information to the second controller.

Abstract: Systems and methods are provided for converting Sequential Function Chart (SFC) logic to function block logic for execution by a programmable controller. In one embodiment, a method includes 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.
