Abstract
The invention relates to a method for adjusting the data transmission rate in a fieldbus system () which is suitable to control safety-critical processes and which comprises at least one subscriber () connected to a fieldbus (), wherein in a first phase the subscriber/subscribers log on at a unit (central unit) centrally connected to the fieldbus with a first low data transmission rate. In a second phase the central unit () sets the data transmission rate at the subscriber/subscribers () to a predetermined higher second value. In a third phase the subscriber/subscribers () log on again at the central unit with a higher data transmission rate; and the central unit () shuts down the fieldbus () if it detects a deviation of the number of subscribers () logged on in the first and the third phase. The invention also relates to a fieldbus system for implementing said method
