Method and device for monitoring and disconnecting control units in a network and a network
First Claim
1. A method for monitoring a plurality of control units in a network, comprising the steps of:
- providing to each control unit a security function for detecting a plurality of errors;
assigning a monitoring routine selected from a plurality of monitoring routines to each error;
assigning a shutdown matrix that is subdivided according to the plurality of errors to the security function;
selecting at least one of the plurality of monitoring routines according to the errors present in the shutdown matrix, wherein;
depending on at least one first condition, the shutdown matrix contains a plurality of shutdown strategies; and
on detection of at least one of the plurality of errors by one of the plurality of monitoring routines and depending on at least one of the at least one first condition and at least one second condition, performing one of the plurality of shutdown strategies in the network to shut down at least one of the plurality of control units.

Abstract
A method for monitoring control units in a network is described, each control unit including a security function for detecting errors, a monitoring routine being assigned to each error and a plurality of monitoring routines being available, a shutdown matrix which is subdivided according to errors being assigned to the security function, at least one of the monitoring routines being selected from the plurality of monitoring routines according to the errors present in the shutdown matrix, depending on at least one first condition, the shutdown matrix containing various shutdown strategies, and on detection of at least one error by the monitoring routine, one of the shutdown strategies is carried out in the network, depending on at least the first condition and/or at least one second condition, at least one control unit in the network being shut down.
