An EXCEL5-based application that reports exceptions from a database of PI tags, PI-PC expressions, and other data. Exceptions are identified by comparing current/minimum/maximum values against limits. The spreadsheet format in combination with PI-PC DataLink enables the report to automatically: adjust limits for changing operating targets, select between alternate operating modes, suppress nuisance exceptions, and regroup similar exceptions based on user-defined criteria. Tables and charts, including related tag information, may be generated for any selected tag or expression directly from the exception report.
