A logic controller includes a memory for storing representations of boolean logic. The boolean logic includes AND and OR boolean logic functions having target values and a plurality of inputs. The processor of the logic controller has input/output circuitry and communications circuitry which provide a plurality of input/output digital logic signals. The processor employs the digital logic signals and solves the boolean logic representations. A firmware routine solves each boolean logic functions when the value of any of its inputs is equal to its target value.
Cet automate programmable comprend une mémoire de stockage de représentations de logique booléenne, laquelle se compose de fonctions logiques booléennes ET et OU comportant des valeurs cibles et plusieurs entrées. Le processeur de l'automate programmable possède des circuits d'entrée/sortie et des circuits de télécommunication fournissant plusieurs signaux logiques numériques d'entrée/sortie. Ce processeur emploie les signaux logiques numériques et résout les représentations logiques booléennes. Une routine de microprogrammation résout chaque fonction logique booléenne lorsque la valeur de l'une quelconque de ses entrées est égale à sa valeur cible.
