Method and system for converting ladder logic to boolean logic in a process control system

摘要

Disclosed herein is a method of converting a ladder logic routine into Boolean logic. Boolean representations of the ladder logic elements of the ladder logic routine are collected in respective logic expressions for each ladder rung of the plurality of ladder rungs defining the ladder logic routine. Boolean logic elements are then resolved from the logic expressions. The Boolean logic elements are then stored in a memory in an order in which the Boolean logic elements are resolved to express the ladder logic routine in accordance with an execution order of the ladder logic routine.
