Abstract (en)
[origin: US2012158363A1] A method for monitoring the functioning of a field device, wherein the field device provides a complex measurement signal, which is produced from a number of individual measurements following one another in time, comprising method steps as follows: the complex measurement signals are stored within a predetermined time window; the occurrence of a predetermined event is monitored in the field device; the stored complex measurement signals are overwritten for the case, in which the predetermined event does not occur within the predetermined time window; for the case, in which 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 event, are frozen, as well as a second defined number of complex measurement signals, which were ascertained in time directly after the occurrence of the predetermined event, are stored.
