1. Method for detection of the activity of a device in a network of distributed stations, in which the activity of one network station is checked by a search request to a network station by means of unprotected transmission protocol which is unprotected against packet losses, with at least one protected transmission protocol in which it is assured that a packet will actually reach its addressee, being made available for data access and/or for controlling a network station,wherein, if the sought network station does not respond to the search request, a data access and/or a control request to this network station is additionally made by means of the protected transmission protocol wherein the inactivity of the addressed network station is confirmed when the fact that the data access and/or the control request has failed is signalled via the protected transmission protocol.
