Reporting on time such as shifts, days, or months is a familiar concept, and many SCADA systems store their process tag history in a continuous time series dataset.
In discrete processes, process information becomes available only when the process has executed e.g., the start/stop times of a product run, machine cycle or filter backwash.
For systems that log continuously, the discrete time frames are crucial to retrieving the appropriate process data.
XLReporter manages the metadata of a discrete process by storing information like its identifier, start and end time using Event Frames.
The Event Frame can be built directly from live events in the process or from an existing transactional database such as a batch or alarm database.
This workshop demonstrates how discrete reports are “stacked” from multiple event frames to produce a hierarchical report e.g., a report of batches displaying detailed information about each lot run over the batch.
