At least one signal is provided by the first processing unit on the basis of at least one communication from the control unit. The at least one provided signal is detected by the second processing unit connected with the first processing unit and is communicated to the control unit by way of the communications network. The at least one communicated signal is checked for the validity thereof by the control unit.
