Abstract

The invention relates to a method for consistent recognition of errors in a distributed real-time computer system, comprising a plurality of node computers which exchange messages via a round-based real-time communication system. According to the invention, the node computers form functional groups. One node computer can be a member of several functional groups. A dedicated functional group member field is allocated to each functional group. A specified bit of the functional group member field is clearly allocated to each node computer involved in said functional group; each node computer manages a local version of the functional group member field of each functional group in which it is involved, and the sending node places the associated bit in the local functional group member field on RIGHT prior to sending a message or WRONG prior to sending a message according to whether the sending node considers that the operability thereof in the functional group is correct or not. The sending node copies all the local functional group member fields thereof in a message to be sent in order to transmit them to a recipient.
