Abstract
Methods, systems, and computer-executable instructions for event synchronized reporting in an process control system are disclosed. 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 times 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 based on both the instances of occurrence of the synchronization parameter as well as historical process control data. Data from various historian databases may be accessed from process control system tools and integrated into a single report.
