1. A method of synchronizing work shift information in a process control system of a process control plant, the method comprising:
executing, by a processor of a computing device in communicative connection with an event historian database of the process control system of the process plant, computer executable instructions stored on a memory of the computing device to:
identify at least one work group in the process control plant, the at least work group including at least one individual;
identify at least one work shift in the process control plant scheduled for the at least one work group;
generate a work change control system event for each work change that has occurred, each work change including a time stamp, and each work change:
i) being indicative of a change in the process control plant from a first work shift to a second work shift, and identifying the first work shift and the second work shift, or
ii) being indicative of a change in the process control plant from a first work group to a second work group, and identifying the first work group and the second work group; and
cause the work change control system event for the each work change to be recorded in the event historian database of the process control system, the event historian database configured to store one or more events that have occurred and that correspond to process data generated by executing a control strategy to control an operation of a process in the process control system, the process control system having one or more control modules in conjunction with one or more function blocks at one or more field devices that perform one or more physical functions in the process plant to execute the control strategy, and the work change control system event and the one or more events corresponding to the process data generated by executing the control strategy being subject to a same data access interface; and
causing, by the computing device, an event synchronized report to be generated, the event synchronized report including at least one synchronized value based on the work change control system event and at least one entry corresponding to historical data, for a process control entity of the process control system, that transpired during an instance of occurrence of the at least one work group or the at least one work shift, and the at least one entry obtained from a centralized database of the process control system.
2. The method of claim 1, wherein the centralized database is at least one of: the event historian database, a continuous historian database, or a batch historian database.
3. The method of claim 1, wherein the computer executable instructions to generate the work change control system event comprise computer executable instructions to generate, as the work change control system event, at least one of:
4. The method of claim 3, wherein the computer executable instructions to generate the work change control system event comprise computer executable instructions to generate, as the work change control system event, at least one of:
5. The method of claim 1, wherein the computer executable instructions to identify the at least one work shift and to identify the at least one work group comprise computer executable instructions to identify the at least one work shift and to identify the at least one work group via a user interface of the process control system.
6. The method of claim 1, wherein the computer executable instructions to identify the at least one work shift and to identify the at least one work group comprise computer executable instructions to obtain an identification of the at least one work shift and to obtain an identification of the at least one work group from a different database.
7. The method of claim 1, further comprising obtaining, by the computing device, an indication of a reporting time interval, and wherein causing the event synchronized report to be generated based on the work change control system event comprises causing the event synchronized report to be generated based on the work change control system event, wherein the work change control system event at least partially occurred during the reporting time interval.
8. The method of claim 1, wherein causing the event synchronized report including at least one synchronized value to be generated comprises causing the event synchronized report to be generated, the event synchronized report including at least one of: an aggregate value, an average value, a percentage, or a total count.
