    Abstract: A sequence of events (SOE) recorder facility in a process control network environment is described herein. The SOE recorder facility is hosted by a networked node that receives digital signal status change (event) data from a networked controller. The sequence of events recorder facility receives a configured set of digital data signals from the controller, temporarily buffers the events in chronological order according to timestamps assigned to the events by their sources (e.g., fieldbus modules). The data is thereafter copied/removed from the buffer and provided to multiple destinations including: a process database that maintains an archival copy of the received event data for rendering event reports, and an SOE client user interface for rendering event logs to printers and/or graphical user interface displays.
