Method for executing sequential function charts as function blocks in a control system

摘要

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.

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.
