Proper management of alarms and alarm data can be a significant source of “hidden capacity” in a plant, as Air Products and Chemicals Inc (APCI) discovered when they implemented a comprehensive alarm management program at their Calvert City, KY ethylene vinyl acetate plant. Air Products was looking to make three improvements to their plant performance: a reduction in off-spec product, an increase in capacity by reducing cycle time and, due to reassignment of duties of the controlroom staff, a better way to present and prioritize alarms.

Alarm Reduction Using Exaplog 'A Case Study'
Information bombards operators today at an ever-increasing rate. This growing barrage of information is driven by additional measurements in the field and by inclusion of business data on the plant floor. Control systems only exasperate the problem if data is not properly filtered and tuned. At best, unorganized, unfiltered data can become useless. At worst, it can lead to confusion and operational mistakes. The job of the control engineer must now reach beyond traditional control to include data management on the plant floor.

PacifiCorp Energy Meets Power Demands with Alarms & Events Server
Our challenge was to implement an Alarms and Events server that extracts and stores event data from the Sequence of Events Recorder in our PLC controls system. Once that was in place, we needed to install a client application to view the stored alarms and events data. Many alarms are generated when a Generator is suddenly stopped. Our Scada system did not provide accurate event time stamp of the alarms or store the alarms for later use, noticeably increasing recovery time from an unplanned shutdown, leaving us unable to meet demands for power, and incurring significant down-time costs.
