Hach WIMS Direct Server-Side Utility to Custom SCADA Request Table (Q13645) is a utility that writes records to a data request table for variables that are cross referenced to a specfied SCADA Interface (Q13605). The Utility reads the WIMS vardesc table, writes records to EDORS.DCS_POINTS_TO_PROCESS based on specific rules. The DCS_POINTS_TO_PROCESS table is then read by a customer supplied utility that calls an Emerson API that calculates the requested data and stores the results in the EDORS.DCS_POINTS_RETRIEVED.
Interface Q13605 then loads the data in EDORS.DCS_POINTS_RETRIEVED.
Example DCS_POINTS_TO_PROCESS Table:
