You can collect, store, and view historical samples of object data with the Metasys Historical Data Management capability. With the information generated by this feature, you can manage energy usage, prove compliance to standards, and diagnose problems in your facility.
Each engine has a local buffer where it stores trend samples. You can configure the size of this buffer, in a number of samples. If a server exists on the site, you can send the trend samples to its database. This database supports backup, restore, and archival of data to long-term storage. You can display trend data as a graph or table of values on the SMP UI. The Trend widget in the Metasys UI displays more recent historical data as a graph. You can also copy trend data to the browser computer’s clipboard, and thereby transfer the data to spreadsheets, databases, and Microsoft Word documents.
The SMP UI makes it easier to detect system-level performance by displaying multiple trends on a single graph or table. You can either predefine multiple trends in a trend study or dynamically select various point trends to display on a single graph using the Trend Viewer or the Trend widget in the Metasys UI. The Site Management Portal UI also offers information on the rate of events, rate of samples, and number of samples that are lost.
