The Hach WIMS Direct Server-Side Interface to WonderWare InTouch HMI imports summarized values into Hach WIMS. The Hach HISTD2HW utility queries WonderWare HISTDATA utility via DDE, and creates Comma Separated Value (CSV) files. These CSV files are summarized by the interface and imported it into Hach WIMS database.

Also, the Best System LLC utility creates CSV files and these can be converted to import files for Hach WIMS using the BSYS2HW utility. The Best System LLC creates CSV files with data points at different times. The BSYS2HW utility fills in every minute gap with the previous known value.
