Sequence of events recorder facility for an industrial process control environment

A method for managing, by a networked computer including a computer-readable medium having computer-executable instructions for a sequence of events management facility, sequence of events data created in a process control network environment including control modules, the method comprising the steps of:

• receiving, by an event data interface, timestamped event data originating from a digital field control process input and provided to the sequence of events management facility via a network communications link;
• maintaining, by a sequence of events server, the received timestamped event data, the maintaining step comprising:
• temporarily storing, by an event buffer interposed between the event data interface and a process database, the received timestamped event data from the event data interface,
• copying the received timestamped event data from the event buffer to the process database, and
• providing, by an event data client application interface, access by sequence of events client applications to the timestamped event data received by the sequence of events management facility, thereby providing user access to sequence of event data based upon timestamped event data originating from a process control system;
• and
• providing, by a buffer writer, received timestamped event data in chronological order to the event buffer.
