OPC A&E archivers are transforming simple alarm and event logs into valuable data stores. An
OPC A&E Archive is different than an OPC DA historian in that it provides a chronological record
of information, allowing quick diagnosis of what led up to a specific event, what the cause was,
and how was it handled by operational staff. Most process historians store data by tag, whereas
alarms and events are stored based on time. Historically many controls people would crowd
around trends and printed event logs trying to piece together what just happened. OPC A&E is
instrumental in better handling all of these problems. |
