Method for monitoring a system

A method for monitoring a system that includes a control unit serving as a master, a plurality of control units serving as slaves, and a monitoring module, comprising:

• providing, in reply to an inquiry, in each instance a response from the master and the slaves;
• and
• checking by the monitoring module a joint response provided on the basis of responses of the providing step;
• wherein the joint response is provided taking into consideration one response defined as correct and one true response of the control unit respectively, and
• wherein the joint response g_Antw is ascertained according to the formula:
• g_Antw=g_Antw_d+ΣS_Antw_w (3) taking into consideration a sum of the true responses ΣS_Antw_w of the slaves.

A system, comprising:

• a control unit serving as a master;
• a plurality of control units serving as slaves;
• and
• a monitoring module, wherein in reply to an inquiry of the master and the slaves a response is given in each instance, and the monitoring module checks a joint response provided on the basis of the responses, wherein the joint response is provided taking into consideration one response defined as correct and one true response of the control unit respectively;
• wherein the control unit checks an inquiry as to whether the inquiry is correct or false and in which as a function of this the response is ascertained;
• wherein the response to a correct inquiry is provided as a function of an inquiry identification code defining the inquiry and a control unit identification code defining the control unit, and
• wherein the response Antw to a correct question is ascertained according to the formula:
• Antw=(Frage_Id+1)*Steuer_Id using the inquiry identification code Frage_Id and the control unit identification code Steuerg_Id.

A computer-readable medium having a computer program that is executable by a computer processor, comprising:

• a program code arrangement having program code for monitoring a system that includes a control unit serving as a master, a plurality of control units serving as slaves, and a monitoring module, by performing the following:
• providing, in reply to an inquiry, in each instance a response from the master and the slaves;
• and
• checking by the monitoring module a joint response provided on the basis of responses of the providing step, wherein the joint response is provided taking into consideration one response defined as correct and one true response of the control unit respectively;
• wherein the control unit cheeks an inquiry as to whether the inquiry is correct or false and in which as a function of this the response is ascertained,
• wherein the response to a correct inquiry is provided as a function of an inquiry identification code defining the inquiry and a control unit identification code defining the control unit, and
• wherein the response Antw to a correct question is ascertained according to the formula:
• Antw=(Frage_Id+1)*Steuerg_Id using the inquiry identification code Frage_Id and the control unit identification code Steuerg_Id.
