Verfahren und Vorrichtung zur Steuerung und Aktivierung von miteinander mittels eines Bussystems vernetzten Sensoren und/oder Aktuatoren

摘要

The invention pertains to a process for controlling and activating binary sensors and/or actuators (ASI slaves) that are linked using a bus system and are driven by a host computer through an ASI master, with feedback; the process makes available in a predetermined time characteristic (ASI master software) host computer signals delivered by the ASI slaves onto the bus system, and the ASI master is capable of putting the bus system in a secure state at any point in time. Though structured separately, the host computer is integrated in the ASI master as an autonomous computer. The ASI master software has priority over the host computer software such that at no point can the timing of the ASI master be changed or interrupted by the host computer or the host computer software; instead, the ASI master is capable of interrupting the host computer at any time, and the host computer software delivers its ASI data to the ASI master through an internal interface. Preferably, the ASI master software is decoupled from the software of the host computer, but data are exchanged between them.
