Abstract
A device collects messages, analog and digital signals from modules (e.g., ECUs, Electronic Controller Units) and sensors arranged on measurement objects in one or more distributed control systems. These systems may work with one or several protocols. The collected information can be of a considerable size, e.g., on the order of one several Gbytes, and can come from CAN or MOST systems arranged on machinery or a vehicle. A commentator system has a recording device for speech and/or image messages and these messages are converted to digital signals which may be distributed to a collection unit along with other signals obtained from the distributed system. Different tasks can be divided up between different experts or actors, and the analysis tasks themselves may be simplified.
