The Hach WIMS Indirect 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.
For an example and description of the source data, see the article Source Data Example and Description.
The Interface uses a Collector (Q12784) that exports data from CSV files into OPSDATAXML files that will be read by the Interface. The Collector generates one of these files every hour and contains 60 data point for each tag that is being exported.
