Abstract:
1. A method for monitoring a functioning of a field device, for process and manufacturing automation technology, the method comprising: storing, by the field device, complex measurement signals within a predetermined time window, wherein the complex measurement signal is provided by a field device, and wherein the complex measurement signal is produced from a number of individual measurements following one another in time; and monitoring an occurrence of a predetermined event in the field device; wherein the stored complex measurement signals are overwritten which when the predetermined event does not occur within the predetermined time window; and when the predetermined event occurs within the predetermined time window, both a first defined number of complex measurement signals, which were ascertained in time directly before the occurrence of the predetermined event, are stored, along with a second defined number of complex measurement signals, which were ascertained in time directly after the occurrence of the predetermined event, are stored, wherein: the event to be monitored is ascertained based on the complex measurement signals following one another in time.
