A system (20) for handling data of a process with a primary controller (30) and a redundant controller (40). The primary controller (30) includes a primary processor that is operable to perform tracking data tasks by using a low speed bus to cooperate with a tracker controller (32) for storage of tracking data in a tracker memory. The primary processor is further operable to perform other tasks by using a high speed bus in cooperation with a primary memory (32). The second bus (37) has an operating rate considerably higher (for example, a factor of two or more) than that of the first bus (38).

L'invention concerne un système (20) pour traiter les données d'un procédé à l'aide d'un contrôleur primaire (30) et d'un contrôleur redondant (40). Le contrôleur primaire (30) comprend un processeur primaire permettant d'effectuer le traçage des tâches de données, au moyen d'un bus à faible vitesse pour coopérer avec un contrôleur de traçage (32) pour le stockage de données de traçage dans une mémoire de traçage. Le processeur primaire permet également d'effectuer d'autres tâches au moyen d'un bus haute vitesse en coopération avec une mémoire primaire (32). Le second bus (37) présente une vitesse d'exploitation considérablement plus élevée (par exemple, d'au moins un facteur de deux) que celle du premier bus (38).
