21.5.2                     BEMS Architecture

The BEMS uses a set of ODBC databases on the Project Node to collect real-time data (the default is Microsoft Access). These databases are separate and independent of the databases used for Analog Tag log, Scheduled reports and Data Log Trends.

The SCADA node collects the data for the BEMS and sends it to the Project Node via the WebAccess Network Service (webvrpcs.exe).

The Project Node also generates the BEMS Analysis displays. 

Both the SCADA node (VIEW and ViewDAQ) and the Project Node (BEMS Project Manager) can display the BEMS reports. Although VIEW and ViewDAQ are calling up an ASP page generated by the Project Node.

The SCADA Node and the Project Node can be the same computer.
