Abstract:
This paper will discuss the final implementation of an Improved OPC data logging system and its improvements over the original. The improved solution focused on the hardware, software and administrative components of the system; taking the reliability and performance of each component into consideration. The software components include the database, the data acquisition and logging client application (DALC) and the various OPC servers; the hardware component includes the servers that will run the software components, power management and Redundant Array of Independents Disks (RAID) technologies; and the administrative component includes implementing automated routines to backup the important data and archive old logs.
