Event Analysis Package Process log analyzer helps optimize plant operation Analyzes DCS Event History to Help You Enhance Efficiency The Exaplog Event Analysis Package provides tools for managers, engineers and supervising operators to analyze DCS plant historical logs, and helps balance the process and enhance efficiency. Exaplog uses trend graphs to measure process request - operator action “balance”, and pie charts or tables to analyze event-type distributions, so helps you identify and reduce unimportant/ consequential alarms, identify and improve inefficient operation sequences – and so balance the process and enhance efficiency. Enhance Process Stability: Balance Process Events and Operator Actions The Event Balance Trend (EBT) shows the numerical balance between process requests (events such as alarms and messages) and operator actions (such as tag mode and setpoint changes), and the relative timings of event and operation peaks – which are indicators of process stability and controllability. When, Where, What (3W) Filters Help You Narrow Focus of Analysis Filters allow you to set items to display, set 3W include/exclude conditions and scope – e.g. (time) span, station or event type – in order to deduce the cause of a process unbalance. Filter settings can be saved for reuse. You can sort tables by keys such as message type and station IDs. Event Balance Trend Window (When) Category Sort Window (What) Lack of balance between process requests (+ axis) and operator actions (– axis) can indicate timing of process problems (areas for improvement). Events sorted by category (e.g. alarm, process status change) can be displayed as a pie chart or table. Message Summary Window Point ID Sort Window (Where) Displays time of events, type, and detail in order of event occurrence. Displays events, sorted by frequency, with tag names/station IDs.
