Prosys OPC to Database (OPC2DB) is a stand-alone Windows application used for logging data from OPC servers to databases.
OPC2DB can be run in Windows operating system, which has any Edition (Express, Workgroup, Standard, Enterprise) of Microsoft SQL Server 2005 installed, along with ADO database drivers.
If SQL Server 2005 is locally available, OPC2DB can also generate a local database for the logging. Otherwise the database must exist either locally or on a remote computer where it can be accessed.
