PROBLEM TO BE SOLVED: To provide methods, systems and computer-executable instructions for event synchronized reporting in a process control system.SOLUTION: Events may be synchronized by a synchronization parameter, whose instances of occurrence may be non-contiguous in time. Examples of synchronization parameters may include a work shift, a work group, an individual's on-duty time, a logged-on period of an individual, the execution time of a process control entity, a batch run type, and a procedure or sub-unit of a batch run. Instances of occurrence of the synchronization parameter may be recorded into a process control event database. Event synchronized reports may contain at least one synchronization value on the basis of both the instances of occurrence of the synchronization parameter and historical process control data. Data from various historian databases may be accessed from process control system tools and integrated into a single report. |
