DeltaV™ S-series Sequence of Events Card
PDP_DeltaV S-series Sequence of Events Card
When a process upset occurs, events can take place very rapidly throughout your process area.
In order to correctly determine the cause of the upset, accurate recording and sequencing of the events is essential. DeltaV™ Sequence of Events provides a means of recording the events associated with a process upset, and using highly accurate time stamps to determine the precise order in which they occurred.
