block 15 subsequently in a query block 16 it is checked whether data bus can is functioning properly if so the information received over data bus can is used for further processing function block 17 otherwise the information transmitted over supply line structure pl is used for further processing function block 18 in a function block 19 the information transmitted over data bus can or supply line structure pl is then processed the exemplary method steps represented by function blocks 15 through 19 may be executed in one component 2 3 4 which receives information the exemplary method according to the present invention is terminated in a function block 20 fig3 shows another exemplary embodiment of an exemplary method according to the present invention in which as in the exemplary embodiment of fig2 the information generated is transmitted over both data bus can and supply line structure pl and received by receiving component 2 3 4 in a query block 21 it is checked whether the information transmitted over data bus can is identical to the information transmitted over supply line structure pl according to this exemplary embodiment supply line structure pl for transmitting information is used for a plausibility check if the information transmitted over data bus can is identical to the information transmitted over supply line structure pl it may be assumed that the information has been transmitted without error in a function block.
