CA 2309587

Control program statements are graphically displayed as flowchart logic (42). The runtime engine (32) associated with the process control computer monitors (12) and maintains state data (65) indicating whether a program statement was executed on every pass, on at least one but not all passes. The user is thus provided with useful logic flow information (72) even though the executing program (62) may operate cyclically at a speed faster than the user can directly perceive.

Des instructions de programmes de commande sont affichées graphiquement sous formes d'une logique (42) d'organigrammes. Le moteur (32) d'exécution associé à l'ordinateur de commande de processus surveille (12) et conserve des données d'état (65) indiquant si une instruction de programme a été éxécutée à chaque passage, sur au moins un des passages et non sur tous les passages. L'utilisateur dispose ainsi d'informations (72) utiles relatives à l'organigramme logique même lorsque le programme (62) d'exécution peut fonctionner cycliquement à une vitesse supérieure à ce que l'utilisateur peut directement percevoir.
