Abstract:
A field device in an industrial environment comprises a clock that is synchronized with a clock of at least one other field device. A timestamp generator component creates a timestamp for at least one of an alarm and an event created within the field device, the timestamp accords to the synchronized time. An alarm generator component analyzes data produced and/or consumed by the field device and generates an alarm and/or event based at least in part upon the analysis.
