Checking interface component involves processor initiating check by sending data message to interface component, carrying out check using returned stored values emulating sensor values

摘要

The method involves a processor (1) initiating the check by sending a data message to the interface component (2), which transfers sensor values to the processor and returns a second data message in response containing permanently stored values. The processor caries out the interface component check using the values, which emulate sensor values. Independent claims are also included for the following: an arrangement for implementing the method.
