The Hach WIMS Direct Server-Side Interface to Trihedral VTS HMI imports data from Trihedral Engineering Limited's VT SCADA System into Hach WIMS.

The interface was developed to query data from the Trihedral VTS HMI History tables using the VTS ODBC Driver.  The interface requires that the VTScada default Historian Data Storage option is used which saves historian tags to a VTScada proprietary database system within the application's data folder.  The interface then queries data from the VTScada ODBC Server, an optional component of VTScada that must be purchased with your VTScada license agreement, via SQL Statements. 

You must install the VTScada ODBC driver - run VTSODBCDriverInstall.exe program from VTScada to install the driver.
