| 摘要 |
The invention relates to a method for temperature management in a network ( 1 ) with ring topology, wherein control devices ( 2 ) exchange data via the network ( 1 ) by means of transmitting/receiving units. The object of the present invention is to find a method and a data bus system which increases the fail safety of a network ( 1 ) with ring topology. For this purpose, the temperature near to the transmitting/measuring unit of at least one control device ( 2 ) is measured. As soon as the temperature at the transmitting/receiving unit ( 2 ) of the control device exceeds a predefined critical temperature T<SUB>krit</SUB>, the transmitting/receiving unit is switched off and wakeup requests put onto the network ( 1 ) by the control devices ( 2 ) are blocked.
