Abstract: The method is characterised in that comparison operations (31) which can be evaluated by an evaluation routine (4) can be formulated at the time the programme (8) of the control device (1) is running and in that actions (32, 33) that can also be formulated at the time the programme (8) is running are triggered according to the result of the respective comparison operation (31). This enables the control device (1) to be diagnosed and/or monitored without interrupting its operation.

Abstract: A bus controller for an electronic device which has an intelligence (or processor) of its own and a memory having a plurality of individually addressable memory locations which are connected with each other via a system bus. The bus controller can be connected with at least the memory and a network bus. The network bus serves for networking several electronic devices with each other (including the electronic device). The bus controller manages at least one request-receipt queue with queue elements for requests to be received over the network bus, wherein the queue is organized as a double-linked list.
